Physiology of the Respiratory System

Spread the love

Physiology of the respiratory system refers to the act of respiration, also known as breathing or pulmonary ventilation. Pulmonary ventilation involves repetitive cycles of inhalation and exhalation, in which movement of oxygen happens from the outside environment to the cells within tissues, followed by the removal of carbon dioxide in the opposite direction. A pressure difference between air pressure within the lungs and the air outside of the body causes air to flow in and out of the lungs.

Common Respiratory Terms:

  • Eupnoea: respiratory rate at rest
  • Bradypnoea: decreased respiratory rate
  • Tachypnoea: increased respiratory rate
  • Apnoea: temporary cessation of breathing
  • Dyspnoea: difficulty breathing
  • Orthopnoea: difficulty breathing when laying down
  • Respiratory Arrest: permanent breathing cessation
  • Hyperventilation: fast breathing rate in which Carbon Dioxide is expelled faster than it is produced, lowering the Carbon Dioxide level in the blood leading to an increase in the blood pH
  • Hypoventilation: slow breathing rate in which Carbon Dioxide in the blood is increased due to not expelling it at the same rate as it is produced

Normal Respiratory Rates:

  • Adults: 12-20 breaths per minute
  • Children: 18-30 breaths per minute
  • Infants (up to 1 year): 30-60 breaths per minute

Respiratory muscles used in quiet inspiration:

  • Diaphragm – lowers to increase the thoracic cavity depth
  • External Intercostal Muscles – elevate the ribs leading to widening of the thoracic cavity

Respiratory muscles used in forced inspiration:

  • Sternocleidomastoids and Pectoralis Minor – elevate the sternum and ribs leading to the widening of the thoracic cavity
  • Scalenes – elevate ribs 1 and 2 leading to the widening of the thoracic cavity
  • Internal Intercostals (part of) – elevate the ribs leading to widening of the thoracic cavity

Respiratory muscles used in quiet expiration:

  • Diaphragm
  • Thoracic Cage
  • Lung Elasticity

Respiratory muscles used in forced expiration:

  • Internal Intercostals (part of)
  • Rectus Abdominis
  • Internal and External Obliques
  • Transversus Abdominis

Neural Breathing Control

Breathing happens through repetitive brain stimuli within the medulla oblongata:

Inspiratory neurons activate during quiet and forced inspiration, firing impulses leading to the diaphragm (through the phrenic nerve) and the external intercostal muscles (through the intercostal nerves) contracting. The inspiratory muscles relax when the inspiratory neurons stop firing, causing expiration.

Expiratory neurons activate during forced expiration.

The Respiratory Rate is affected by the Respiratory Centres, namely:

  • Central Chemoreceptors – found in the medulla oblongata
  • Peripheral Chemoreceptors – found in major blood vessels

These respond to the changes in Oxygen, Carbon Dioxide levels and pH of the blood. For example, if there is a decrease in Oxygen level, an increase in Carbon Dioxide level and a decrease in the blood pH, the Respiratory Rate is automatically increased so as to compensate for the lack of Oxygen.

Breathing can be manipulated through the cerebral cortex, which sends impulses to the diaphragm and intercostal muscles, bypassing the medulla oblongata and pons in the process. However, an increase in Carbon Dioxide level reduces the ability to control breathing manipulation.

The Pressure Gradient

The pressure gradient is the difference between the atmospheric pressure (pressure of the outside air) and the intrapulmonary pressure (pressure within the lungs). Pressure and resistance work together in determining airflow.

During inspiration, the rib cage elevates and the diaphragm depresses and flattens, leading to an increase in the thoracic volume, causing the intrapulmonary pressure to fall when compared to atmospheric pressure. Thus, air flows into the lungs.

During exhalation, the rib cage descends and the diaphragm rises in the form of a dome. Lungs recoil to a smaller volume, which causes the intrapulmonary pressure to increase when compared to atmospheric pressure. Thus, air flows out of the lungs.

Resistance to airflow depends on:

  • Thoracic Wall Compliance – if the thoracic wall tissues are non-compliant, the thoracic cavity doesn’t increase, which inhibits the lungs to increase in size during inhalation
  • Bronchial Diameter – bronchoconstriction causes resistance to airflow
  • Alveolar Surface Tension – alveoli walls are lined by a thin film of water that creates tension at their surface

Respiratory Volumes

Tidal Volume (TV) is the volume of air inspired or expired in a normal respiratory cycle.

Inspiratory Reserve Volume (IRV) is the maximum volume of air that can be inspired during forced respiration. This does not include the tidal volume (forced inspiration amount).

Expiratory Reserve Volume (ERV) is the maximum volume of air that can be expired during forced respiration. This does not include the tidal volume.

Residual Volume (RV) is the volume of air left in the lungs following forced expiration. RV allows gas exchange to happen between respiratory cycles, allowing the alveoli to stay inflated.

Respiratory Capacity refers to the combination of more than one volume.

Total Lung Capacity (TLC) is the combination of all lung volumes:

Tidal Volume + Expiratory Reserve Volume + Inspiratory Reserve Volume + Residual Volume = Total Lung Capacity

Vital Capacity (VC) is the amount of air an individual can move in or out of the lungs:

Tidal Volume + Expiratory Reserve Volume + Inspiratory Reserve Volume = Vital Capacity

Inspiratory Capacity (IC) is the total amount of air that can be inhaled:

Tidal Volume + Inspiratory Reserve Volume = Inspiratory Capacity

Functional Residual Capacity (FRC) is the amount of air remaining in the lung following a normal tidal expiration:

Expiratory Reserve Volume + Residual Volume = Functional Residual Capacity

A PEFR measures Forced Expiratory Volume (FEV), which is the maximum amount of air that can be forcefully exhaled in one second.

IV Complications – Signs & Symptoms, Prevention and Management

Spread the love

More than 90% of hospitalised patients receive some form of IV therapy. Unfortunately, about 1/5 of these patients experience IV complications due to lack of administration care and adequate monitoring.

Phlebitis

IV complications
Retrieved from https://casereports.bmj.com/content/2016/bcr-2016-216448.full?sid=39b2cfd9-37f2-447d-bb40-64e8335a1d3c on 2nd April 2021

Phlebitis is the inflammation of the vein which is caused whenever the used cannula is too large for the chosen vein, or when the cannula is not secured in place. Using the smallest cannula possible depending on the patient and the fluid being administered will reduce the chance of phlebitis to occur during IV therapy administration.

Signs & Symptoms:

  • warm to the touch around the insertion site
  • redness and/or tenderness at insertion site or along the vein
  • bulge over the vein

Management:

  • at first sign or symptom of phlebitis stop IV infusion immediately
  • apply warm compresses onto the area
  • if further IV infusion is required, insert a new catheter into a different vein and into a different site, preferably choosing a bigger vein and opposite arm
  • document patient condition and management

Air Embolism

IV complications
Retrieved from https://vascularaccess.com.au/2017/05/14/air-embolism-understanding-why-it-occurs-and-how-to-prevent-it/ on 2nd April 2021

Air Embolism a.k.a. gas embolism occur when one or multiple air bubbles enter the blood stream through a vein or artery and blocks it. Air embolism is one of the most dangerous IV complications as it can cause death.

Signs & Symptoms:

  • blue skin hue
  • anxiety
  • dizziness
  • nausea
  • headache
  • muscle pain
  • joint pain
  • hypotension
  • dyspnoea
  • gasp reflex
  • persistent cough
  • tachypnoea
  • respiratory failure
  • shock
  • confusion
  • syncope / loss of consciousness
  • seizures
  • stroke
  • syncope

Management:

  • if air embolism is noted, flush or infusion administration should be stopped immediately and the rotating haemostatic valve (RHV) should be fully opened
  • if patient is unresponsive administer first aid, prioritising airway (A), breathing (B) and circulation (C) and if necessary resuscitate. Once resuscitated and stabilised, patient should be administered 100% oxygen treatment through a non-rebreather mask to ensure full body oxygen perfusion.
  • document patient condition and management

IV Site Infection

IV complications
Retrieved from https://sites.google.com/site/refreshersfornurses/infection on 3rd April 2021

A localised infection around the IV cannula site can be prevented by use of veins that are not small or fragile, not in extremities, not in areas that may need to be flexed and not in veins situated in sites with oedema or neurological impairment. Adherence to IV therapy safety procedures, maintaining a clear, dry dressing and frequent monitoring can help lessen the chance of infection.

Signs & Symptoms:

  • redness
  • swelling
  • burning sensation
  • discomfort
  • discharge
  • increase in temperature

Management:

  • when noted, infusion should be stopped immediately
  • remove cannula
  • clean site of infection
  • administer antibiotics as prescribed
  • monitor patient’s vital signs
  • document patient condition and management

Flare Reaction

IV complications
Retrieved from https://www.bjmp.org/content/unusual-reaction-iv-pethidine-case-report on 3rd April 2021

Venous flare reaction is usually a localised allergic response to the administration of an irritant via IV. To minimise risk for a flare reaction, patient’s allergy history should be taken prior to therapy administration, and administration should ideally happen slowly through an infusion pump. Additionally, monitor patient during infusion administration for any pain or discomfort.

Signs & Symptoms:

  • redness along the vein or at cannula site
  • tenderness
  • itchiness
  • warm to the touch
  • swelling
  • hypotension
  • anaphylaxis

Management:

  • stop irritant administration immediately
  • administer antidote if available
  • monitor for worsening of patient condition
  • document condition and management

Extravasation

IV complications
Retrieved from https://www.researchgate.net/publication/319654406_Chemotherapy_Extravasation_Management_21-Year_Experience on 3rd April 2021

Extravasation is the unintentional leakage of vesicant fluids or medications into the vein’s surrounding tissue. It can be prevented by ensuring proper drug dilution as per recommended guidelines prior to IV administration.

Signs & Symptoms:

  • discomfort, blanching and/or burning sensation at IV site
  • cool sensation at IV site
  • swelling at or right above IV site
  • blistering
  • skin sloughing

Management:

  • stop IV therapy administration immediately by disconnecting IV tube from cannula
  • aspirate any residual drug
  • administer antidote if available
  • document patient condition and management

Infiltration

IV complications
Retrieved from https://sites.google.com/site/refreshersfornurses/infiltration on 3rd April 2021

Infiltration is the accumulation of fluid in the IV surrounding tissue caused by the needle puncturing the vein wall or by eventual needle misplacement. Stabilising chosen vein extremity and taping cannula firmly to the skin can help prevent infiltration.

Signs & Symptoms:

  • little or no flow of IV infusion or bolus
  • cool to the touch
  • hard to the touch
  • swollen and pale infusion site
  • fluid leakage from infusion site
  • pain, tenderness, irritation and/or burning sensation at infusion site

Management:

  • stop infusion immediately and remove cannula
  • elevate effected extremity
  • apply warm compresses to encourage absorption (apply ice to the swelling if noticed within 30 minutes of infiltration onset)

Thrombophlebitis

IV complications
Retrieved from https://www.gastroepato.it/en_tromboflebiti_superficiali.htm on 4th April 2021

Thrombophlebitis is an inflammation that causes the formation of a blood clot, which blocks one or more veins, usually in the legs. Superficial Thrombophlebitis occurs when the affected vein is closer to the surface of the skin, whilst Deep Vein Thrombosis (DVT) occurs when the affected vein is at a deeper level.

To prevent thrombophlebitis, one needs to avoid prolonged periods of standing and elevate legs when sitting down. Improving blood circulation helps. This can be done by regular exercise.

Signs & Symptoms:

  • sudden or gradual swelling in the affected area
  • tenderness and/or pain in the affected area
  • redness or discolouration in the affected area
  • warm to the touch

Management:

  • apply heat to affected area
  • elevate
  • use of NSAIDs
  • wear compression stockings

Haematoma

IV complications
Retrieved from https://www.myiv.com/category/blog/page/11/ on 4th April 2021

A haematoma is leakage of blood from the blood vessel into the surrounding soft tissue. As one of the possible IV complications, a haematoma occurs when an IV catheter passes through multiple walls of a vessel, or when not enough pressure is applied to an IV site after catheter removal.

Signs & Symptoms:

  • redness
  • swelling
  • pain
  • disfiguring bruises

Management:

  • during the first 24hrs from the formation of a haematoma apply ice packs wrapped in cloth for 20 minutes (you can repeat this multiple times)
  • after the first 24hrs from the formation of a haematoma apply warm, moist compresses to the affected site for 20 minutes (you can repeat this multiple times in the second 24hrs post haematoma formation)
  • do not massage affected area
  • compress and elevate if affected area is a limb

Electrolyte Imbalance

IV complications

Electrolytes are minerals that carry an electrical charge in the blood, tissues, organs and everywhere within the body. An electrolyte imbalance is the result of too much or too little water.

Signs & Symptoms:

  • fatigue
  • lethargy
  • nausea and vomiting
  • diarrhoea or constipation
  • dysrhythmias
  • tachycardia
  • convulsions or seizures

Management:

  • monitor for dehydration
  • monitor ECG for prolonged QT interval
  • IV fluids
  • diet changes (eating more foods containing lacking electrolyte)
  • check current drug prescriptions for any possible replacement need (eg. loop diuretics may be changed to potassium-sparing diuretics in the case of loss of potassium)

Acute Hypervolaemia

Retrieved from https://en.wikipedia.org/wiki/Edema on 5th April 2021

Hypervolaemia is a condition in which there is excess fluid in the blood. Whilst an adequate amount of water is necessary for the body to function well, excessive fluid leads to an imbalance, resulting in complications.

Signs & Symptoms:

Management:

  • watch fluid intake
  • minimise sodium intake
  • monitor weight and report any changes and swelling immediately
  • diuretics
  • if present manage other existing comorbidities such as heart failure and chronic kidney disease to minimise hypervolaemia

Anaphylaxis

Retrieved from https://www.healthline.com/health/anaphylaxis on 5th April 2021

Anaphylaxis is a severe immediate hypersensitive reaction which is usually triggered by an allergen. Identifying the signs and symptoms of an anaphylactic shock is crucial as this is a life-threatening situation requiring immediate treatment.

Signs & Symptoms:

  • hives / itching
  • flushed or pale skin
  • dizziness or fainting
  • hypotension
  • bronchoconstriction / swollen tongue and/or throat leading to wheezing and dyspnoea
  • weak rapid pulse

Management:

  • epinephrine shot administered immediately
  • maintain a patent airway
  • if required, antihistamines and / or steroids may also be administered
  • oxygen administration
  • bronchodilators
  • monitor blood pressure, heart rate and oxygen saturation

Speed Shock

Retrieved from http://www.cwladis.com/math104/lecture6.php on 5th April 2021

Speed Shock is a systemic reaction to a drug being administered rapidly, leading to toxicity onset. An infusion device ensures that a drug is administered at the recommended rate.

Signs & Symptoms:

  • headache
  • flushed face
  • chest tightness
  • irregular pulse
  • syncope
  • loss of consciousness
  • shock
  • cardiac arrest

Management:

  • Stop IV immediately

  • Report reaction
  • Do not leave patient unattended
Retrieved from https://www.pedagogyeducation.com/Class-Catalog/Infection-Control/Goal-Zero-Catheter-Related-Blood-Stream-Infections.aspx on 5th April 2021

Catheter Related Bloodstream Infection (CRBSI) is a complication resulting from the use of IV catheters. Septicaemia can also result from a CRBSI, causing a prolonged hospital stay. CRBSI can be prevented using an aseptic non-touch technique (ANTT) during insertion, use of PPEs, disinfecting external surfaces of the catheter hub and connecting ports, and removing and/or replacing at the appropriate time.

Signs & Symptoms:

  • fever
  • chills
  • hypotension
  • signs of infection proximal to the insertion site of the PVC (peripheral venous cannula)

Management:

  • removing catheter immediately when a CRBSI is noted
  • administrating antibiotics
  • maintaining infection control

Adverse Drug Reactions

An adverse drug reaction (ADR) is a harmful or unpleasant reaction resulting from an IV infusion which can be caused by a single or a combination of drugs. An ADR can be prevented by avoiding consumption with alcohol, reading instructions and consuming medication only as prescribed, and taking note of any previous reactions to the same ingredients. Avoid taking over-the-counter medications with vitamins.

Signs & Symptoms:

  • phlebitis
  • infiltration
  • extravasation
  • speed shock
  • shock
  • cardiac arrest
  • venous spasms (presenting as cramping and pain above IV site)

Management:

  • stop drug administration immediately

Chronic Pain Management – The Nurse’s Role In Pain Management & Care

Spread the love

Acute pain acts as a warning, signalling that you’ve been hurt. It is typically mild and short-lasting, or severe, lasting for a few weeks or months, disappearing when the underlying cause of pain is treated (eg. surgical wounds, broken bones and childbirth). On the other hand, chronic pain can last for months or years, and has no definite cause (eg. arthritis, back and neck pain, fibromyalgia, CRPS and headaches). Chronic pain management can help reduce the negative impact on an individual’s quality of life, however, complete pain relief is quite difficult to achieve.

Ineffective chronic pain management can be the result of:

  • inaccurate pain assessment leading to inadequate pain treatment
  • opioids misconceptions by clinicians and patients
  • fears about pain management side effects

Chronic Pain Management Patient Journey:

  1. Consultation resulting in a referral
  2. Outpatient visit
  3. Consultant review
  4. Follow-up

The nurse’s role during an outpatient visit requires him/her to:

  • Listen and assess the patient’s situation
  • Evaluate and take action
  • Advise
  • Organise care and/or treatment
  • Prepare the patient for any required pain intervention
  • Follow-up
  • Document all information

  • Ibuprofen
  • Naproxen
  • Diclofenac
  • Arcoxia
  • Analgesic Creams
  • Paracetamol
  • Sulphadol

Injection Based Interventions

  • Occipital Nerve Block
  • Trigger Points Injections
  • Sympathetic Block
  • Joint Infiltration – Facets, Sacroiliac, Knees & Elbows (effect may last for up to a year, but may also prove to be ineffective, depending on the individual)
  • Epidural (usually infiltrated with Fentanyl, Morphine or Steroid)
  • Dorsal Root Ganglion PRF
  • Radiofrequency Neuroablation / Denervation (effect lasting for 6-12 months, at times for years, however, procedure is more risky and may result in deficits in the lower limbs…usually combined with other interventions including multimodal analgesia and alternative therapies)

Medication used in most spinal injections is Lidocaine, which is a local anaesthetic. Marcaine is a different type of anaesthetic which is used along with a strong anti-inflammatory steroid, namely Depomedrone.

Long Term Medication for Chronic Pain Management

  • Codeine
  • Tryptizol
  • Baclophen
  • Lyrika / Pregabalin
  • Tramodol
  • Palexia / Tapentadol
  • Morphine
  • Fentanyl Patches
  • Methadone
  • Cannabis Oil

Intrathecal Pump and Dorsal Column Stimulator

Intrathecal drugs are perceived to be much stronger than oral medication, making this an ideal option for nerve pain that is difficult to treat.

The intrathecal pump’s battery life span is usually 5-7 years long. The pump is refilled with medication by inserting a needle through the skin directly into the filling port located at its centre. Medication dose adjustments can be made through an external program device.

Prior to implant, a trial is performed to assess toleration. Pump provides relief in spasticity and chronic pain through a catheter, releasing a medicinal directly to the intrathecal space (spinal cord area), preventing pain signals from reaching the brain.

In the Spinal Cord Stimulator, an electrode (or sometimes multiple electrodes) is implanted through the skin into the epidural space of the spinal canal. An electrical stimulation that feels like a gentle vibratory sensation causes the pain sensation to be blocked. The electrodes used in this procedure are highly expensive, and so, a trial with a temporary system is necessary prior to a permanent device being implanted.

Physiotherapy for Respiratory Conditions in Adults and Paediatrics

Spread the love

A physiotherapist assesses, treats, monitors, follows and cares for patients with lung and heart disorders. Breathing disorders targeted by physiotherapy include asthma, bronchitis, emphysema, cystic fibrosis, pneumonia, chest trauma as well as cardiac-induced respiratory failure. Physiotherapy for respiratory conditions includes basic chest physiotherapy, which aims to provide:

  • assistance for airway clearance – using chest physiotherapy
  • optimum functional capacity – catering for the patient’s full functioning
  • problem oriented care – finding out what the cause of the problem is and then managing the discovered problem
  • holistic management – patient is seen as a whole, where not the initial complaint is targeted, but anything else associated with the same patient, thus, a patient requiring basic chest physiotherapy may also be provided with assistance regarding obesity, nutrition and lifestyle changes

Physiotherapy for respiratory conditions challenges include:

  • inability to clear chest
  • inability to breathe easily
  • reduced exercise tolerance
  • reduced lung capacity
  • reduced functional capacity
  • poor self management due to being unable to function normally

Chest Physiotherapy (CPT) provides a method for bronchial hygiene by:

  • Turning
  • Postural drainage
  • Chest percussion and vibration
  • Specialised cough techniques a.k.a. directed cough

These strategies help in reducing dyspnoea, improving ventilation and perfusion and increasing respiratory function by causing bronchial secretions to move to the central airway via gravity.

NOTE: CPT is contraindicated for asthma patients. Instead, a different technique is used for asthma where the patient is encouraged to huff instead (as if misting a mirror with their breath).

CPT Indications:

  • poor exercise tolerance
  • decreased mobility
  • potential postural deformities
  • mucus plugging causing acute lung or lobar collapse
  • increased secretions or secretion retention affecting respiration

Low secretion level should be targeted by gentle methods of excretion; High secretion level should be targeted by tougher methods which provide more efficacy, whilst taking into consideration how frail the patient is.

Physiotherapy for Respiratory Conditions

NOTE: With reference to the above positions, patients who have undergone gastric surgery, facial surgery or cardiac surgery, as well as the elderly or the frail, SHOULD NOT be positioned tipping down.

Vibrations vs Shakings: Vibrations are gentler than shakings; shakings are of high magnitude, thus vibrations are preferred where the patient is frail eg. elderly or has osteoporosis.

Manual Hyperinflation: an ambubag is used to expand lung eg. if lung has collapsed. In case of secretions, the use of an ambubag is combined with shakings to clear secretions.

With reference to the above image:

Breathing Exercises Cycle ACBT helps with reducing heart rate, reducing anxiety and reducing respiratory rate;

Breathing Control: small breaths that are controlled; help expand lungs

Thoracic Expansion: larger breaths; Sitting low limits breathing capacity; breathe deeper to encourage more air into the alveoli…air seeps behind secretions and mobilises them when breathing out

FET Forced Expiratory Technique: completes cycle by facilitating excretion of secretions

Physiotherapy in the ITU Setting

Patients in acute, critical and ITU setting are in poor health conditions. It is indicated that with every day spent in bed, patients lose 30% of their muscle fibers. Physiotherapy for respiratory conditions in such settings is focused on:

  • Deconditioning – reversible changes in the body due to lack of physical activity.
  • Impaired Airway Clearance – poses risk for the patient to develop an infection, major atelectasis and other related problems such as impaired gas exchange and airflow limitation.
  • Atelectasis – a complete or partial collapse of the entire lung or lobe of the lung due to alveoli deflating or possible filling with alveolar fluid; Atelectasis is one of the most common respiratory complications post surgery.
  • Intubation avoidance – insertion of an endotracheal tube through the mouth and into the airway for ventilation purposes; assists with breathing during anesthesia, sedation, or severe illness.
  • Weaning failure – failure in reducing ventilatory support, where patient is unable to breathe spontaneously and so cannot be extubated.

Physiotherapy for respiratory conditions improves respiration through airway clearance and improvement in gas exchange, as well as muscle function through the prevention of muscle atrophy, loss of strength, loss of muscle fiber, and polyneuropathies (peripheral neuropathy / damage of multiple nerves).

In ITU setting, pulmonary infections can happen due to ventilator acquired pneumonia and through lobar atelectasis. Prevention of lung collapse is also very important in ITU setting. Techniques mentioned further above help increase lung expansion. Upkeep of the respiratory system helps in avoiding late development of complications.

Pulmonary exacerbation can lead to:

  • muscle weakness
  • haemoglobin reduction
  • reduction in testosterone levels in both males and females
  • hypoxia
  • systemic inflammation
  • possible concomitant heart failure

Paediatric Physiotherapy for Respiratory Conditions

Physiotherapy can be initiated from as early as a few days after birth. In intensive care, physiotherapy can reduce the risks associated with endotracheal tube obstruction.

In short term treatment, the main aim is that of eliminating obstructive secretions from the airway, which reduces breathing work, improves efficiency of mechanical ventilation, improves gas exchange, prevents or resolves complications, leading to early weaning from ventilator use.

In long term treatment, the main aim is that of preventing postural deformities, improving tolerance to exercise and providing better quality of life.

A ventilated paediatric patient risks:

  • ventilator associated pneumonia
  • oxygen toxicity
  • hyperinflation
  • atelectasis
  • impaired mucociliary clearance
  • decreased funcitonal residual capacity (FRC)
  • endotracheal tube insertion
  • inadequate humidification of vent gases leading to increased secretions which then cause obstruction, infection, atelectasis = chronic disease.

Paediatric breathing mechanics are different. Babies are more fragile and need to be treated in a more gentle way. Constant monitoring and lung clearance help in avoiding the development of ventilator associated pneumonia. Oxygen should be monitored frequently as excessive oxygen in babies can cause blindness, mental and brain related problems.

Physiotherapy is contraindicated (unless advised otherwise) in:

  • very premature babies
  • unstable / severely ill child
  • pulmonary haemorrhage
  • pulmonary oedema
  • pulmonary hypertension
  • raised intracranial pressure
  • platelet count less than 50 (in less than 100 it may be indicated with extra care)

NOTE: Bronchiolitis is a very common condition affecting babies up to around 4 years of age. Bronchiolitis restricts respiratory function.

Palliative Care

If a patient has no possible treatment option (such as in lung cancer, cystic fibrosis, COPD), quality of life can still be improved through physiotherapy. It helps the patient to cope and live comfortably with his/her condition.

Dosage Calculations for Nursing Students – Accurate Patient Safety & Care

Spread the love

Accuracy in dosage calculations and solution rates is a highly important aspect of safe nursing care. The following notes and examples provide simple methods of dosage calculations, solution rates and conversion tables that can help provide safe easy methods to ensure drug administration safety for our patients.

Volume (ml) / Time (mins) X Drop Factor = Drip Rate (drops/minute)

Drop factor is usually 10, 15 or 20 (unless indicated otherwise, drop factor should be assumed as 20)

Example 1: Jane has an order for 500mg Clarithromycin every 6 hours. The drug comes in 250mg capsules. How many capsules does Jane require?

1 capsule contains 250mg, so since Jane requires 500mg, the nurse should administer 2 capsules.


Example 2: A digoxin ampule contains 500mcg in 2ml. If a patient is prescribed 350mcg, what volume should he receive?

500mcg = 2ml; 350mcg =?

2ml x 350mcg = 700 / 500 = 1.4ml


Example 3: 625mg are prescribed to a patient. Tablets come in 1.25g each. How many capsules should the nurse administer?

1250mg = 1 capsule; 625mg =?

625mg / 1250mg = 0.5 = half a tablet


Example 4: Heparin contains 5000units per ml. How much Heparin should be administered if a patient requires 6500units?

5000 units = 1ml; 6500 units =?

6500 units / 5000 units = 1.3ml


Example 5: A patient is prescribed IV paracetamol at 15mg per kg. The patient weighs 45kgs. How much paracetamol should be administered by the nurse?

1kg = 15mg; 45kgs =?

45kgs x 15mg = 675mg


Example 6: A patient needs 500ml of 0.9& NaCl. Drip chamber is set to 25ml per hour. How long will the fluid take to be administered to the patient?

25ml = 1hr; 500ml =?

500ml / 25ml = 20 hours


Example 7: 300ml of blood needs to be transfused over 4hrs at 20 drops/ml. What is the drip rate?

volume in ml / time in minutes = 300ml / 240 minutes = 1.25 x 20 (drop factor) = 25 drops per minute


Example 8: A patient is to receive 2lt of 5% Dextrose in the next 15 hours. What is the flow rate?

15hrs = 2000ml; 1hr =?

2000ml / 15hrs = 133ml/hr


Example 9: A patient needs 750ml of 0.9%NaCl to be administered over 9 hours at 10 drops per ml. What is the drip rate?

750ml / 540 minutes = 1.3888 x 10 (drip factor) = 13.88 = 14 drops/min


Example 10: Calculate the required flow rate when administering one litre of fluid over 4 hours.

4 hours = 1000ml; 1hr =?

1000ml / 4hrs = 250ml per hour

IV Drug Preparation & Administration by PVC, Volumetric & Infusion Pump

Spread the love

IV Drug Preparation and Administration by PVC Peripheral Venous Cannula (Venflon)

Considerations

  • Use ANTT (aseptic non touch technique) to maintain sterility
  • Check PVC site during patient washings or every 2 to 3 hours
  • Complications include extravagation, as well as infection, feeling hot to the touch and redness; in such case remove cannula immediately
  • Flushing with 5ml saline using a 10ml syringe helps by reducing pressure, maintaining vein integrity
  • Bolus is administered from the cannula top port while an infusion via a pump is administered through the side port (in this case position a swab beneath port to keep patient clean from any dripping blood and wear gloves to protect yourself from the patient’s blood)
  • IV tubing shouldn’t be used for more than 72 hours

Preparation

  • Prepare supplies
  • Check the expiry date of every item you are using for the procedure
  • Wipe medication and saline bottle tops/caps with 2% Chlorhexidine for 30 seconds and allow to dry
  • Prepare flush with 0.9% saline; use 10ml syringe but flush with 5ml saline. You may prepare a syringe with 10ml saline if administering a bolus in between. In case of an infusion by pump for longer duration prepare only 5ml saline in a 10ml syringe and flush using a new syringe after infusion is administered
  • Prepare required medication dosage following manufacturer instructions
  • Label all medications and do not leave unattended

Method

  • Apply hand hygiene
  • Confirm patient identity, explain procedure and gain consent
  • Check cannula site for phlebitis and/or infiltration and extravasation
  • Wear gloves if opening the cannula side port due to risk of contact with body fluids (patient’s blood)
  • Wipe cannula with 2% Chlorhexidine for 30 seconds and allow to dry
  • Flush with 0.9% saline; use 10ml syringe but flush with 5ml saline…this reduces pressure and maintains vein integrity. Use push-pause technique (helps open any light blockages/crusting).
  • Administer medication at a slow rate or as recommended
  • Flush again with 5ml 0.9% saline
  • Close cannula port with a new port cap
  • Apply hand hygiene
  • Document procedure

Acute Postoperative Pain – Classification Assessment Management & Care

Spread the love

Acute pain is characterised by a quick onset which may be severe, yet lasts for a shorter period of time when compared to chronic pain. Acute postoperative pain should be managed in the best way possible so as to restore or improve the patient’s quality of life, reduce morbidity, facilitate a quick recovery, leading to an early postoperative discharge.

Pain should be classified as acute, chronic or acute-on-chronic, nociceptive, neuropathic or inflammatory. Classification of pain helps in patient assessment as well as treatment.

Acute Pain:

  • immediate onset eg. cut or injury
  • usually lasts less than 3 to 6 months
  • can act as a warning
  • usually easier to treat
  • usually has an end

Chronic Pain:

  • lasts relatively longer than acute pain (more than 3 to 6 months)
  • has no purpose
  • can lead to pain behaviours
  • is very difficult to treat

Nociceptive Pain:

  • caused as a result of an injury eg. bruising, inflammation, fractures, burns
  • includes post-surgery cuts/wounds

Neuropathic Pain:

  • results from a nerve trauma
  • may include components of cancer pain, phantom limb pain, pinched nerve (eg. carpal tunnel)
  • may manifest as widespread nerve damage a.k.a. peripheral neuropathy which is frequently caused by diabetes mellitus

Nociceptive Pain:

Nociceptive pain can be divided into two categories, both of which involve nociceptors, which are the pain-detecting receptors which can be found in the body.

  • SOMATIC PAIN – a sign of tissue damage which may be either superficial or deep (bones, joints, skin, muscle, connective tissue etc). This type of pain is usually described as throbbing, aching and localised.
  • VISCERAL PAIN – originates from inner organs within the body (eg. angina). This type of pain is usually described as dull and is not usually localised.

Why Pain Relief?

  1. BASIC HUMAN RIGHT
  2. PAIN & SUFFERING REDUCTION = restore quality of life
  3. QUICKER RECOVERY – early discharge = lower cost & less sick leave
  4. REDUCING RISK OF DEVELOPING PERSISTENT PAIN
  5. ENHANCING PATIENT SATISFACTION

Acute Postoperative Pain

Factors influencing acute postoperative pain include:

  • lack of patient education
  • fear of analgesia and associated complications
  • inaccurate pain assessment leading to inaccurate pain management
  • lack of human resources

Inefficient postoperative pain relief reduces rehabilitation and functional outcome:

poor pain management = patient immobilisation = longer hospital stay = increased cost of patient care = increased chronic pain development risk = long term disabilities and complications

Complications arising from poor pain management include:

  • increased risk of deep vein thrombosis (DVT)
  • increased risk of pulmonary embolism (PE)
  • increased risk of respiratory problems (eg. pneumonia & hypoxaemia)
  • increased risk of cardiac complications
  • increased heart rate and blood pressure
  • increased gastrointestinal (GI) symptoms (eg. paralytic ileus & anastomotic failure)
  • increased risk of muscoskeletal symptoms (eg. muscle spasms & immobility)
  • increased immunological risks (eg. infection, delayed wound healing, pressure sores)
  • increased psychological risks (eg. anxiety, depression, fatigue, fear & insomnia)

The Nurse’s Role in Acute Postoperative Pain Management

ASSESS = correct preoperative and postoperative pain assessment using the available pain assessment tools such as SOCRATES and Pain Severity Assessment Tool

ADMINISTER = correct administration of safe and effective analgesics

EDUCATE = teach patient about helpful therapies including therapeutic therapy eg. position change

COMMUNICATE = best communication practice includes the patient, caregivers and healthcare professionals

REASSESS = monitor pain level and severity to identify patient improvement or deterioration

DOCUMENT = documentation of all pain management methods used

Patient History

  • Current Pain Medication – seek accuracy regarding drug name, dose, frequency, route and duration
  • Medical History – look for possible drug interactions, allergies and intolerances to certain medications (eg. in patients with renal disease avoid morphine and NSAIDS; in patients with cardiovascular disease check if patient is on any anti-coagulants / avoid NSAIDs)

IMPORTANT: Always treat each patient as a unique individual:

  • don’t assume – every individual has a different perspective
  • evaluate – monitor for painkillers side effects
  • check for interactions – keep a list of the patient’s drugs for interaction monitoring
  • respect religious and cultural considerations – do not judge, respect and empathise; be aware of specific patient needs and beliefs, and explain treatment need within a holistic context

Effective Pain Management

  • regular pain intensity assessment
  • provide written instructions
  • balance analgesia administration (oral, IM, IV and patient controlled analgesia PCA)
  • include alternative methods of pain control
  • educate patient and/or family about pharmaceutical pain management
  • continuous training of medical and nursing staff

PCA – Patient Controlled Analgesia refers to analgesia administered through a pump. It contains a syringe prefilled with pain medication which is connected directly to the patient’s IV line. This pump can be set to deliver a small constant flow of pain medication through a bolus.

Postoperative Pain Control Plan

  1. Identify patient queries
  2. Dispel myths
  3. Address patient concerns including those about opioid use and addictions
  4. Address fear of tolerance
  5. Age-related pain expectation

Multimodal Analgesia

  • NSAIDs (non-steroidal anti-inflammatory drugs)
  • Opioids (have effects similar to those of morphine)
  • Anticonvulsants (suppress the excessive rapid firing of neurons during seizures)
  • Antidepressants (used to treat major depressive disorder, some anxiety disorders, some chronic pain conditions, and to help manage some addictions eg. valium and amitriptyline – may cause drowsiness leading to an increased risk of falling)
  • Non-pharmaceuticals (eg. heat reduces pain and muscle spasms; ice reduces swelling, pain and tissue damage; physiotherapy and occupational therapy improve mobility and decrease pain)

Common Painkillers

  • Paracetamol – headaches, muscle aches, arthritis, backaches, toothache, cold and fever
  • Voltaren, Diclofenac and Catafast – NSAIDs
  • Codeine – opioid/narcotic used for pain and as a cough suppressant
  • Pethidine – opioid used frequently as a postoperative analgesic
  • Morphine – opioid pain medication
  • Tramodol – narcotic that treats moderate to severe pain
  • Tapentadol and Palexia – opioid/narcotic used to treat moderate to severe pain
  • Lyrica and Pragiola (Pregabalin) – antiepileptic drug
  • Gabapentin – antiepileptic drug

Opioids Adverse Effects may include:

  • respiratory depression and sedation
  • nausea and vomiting
  • allergies
  • confusion and delirium especially in the elderly
  • constipation

The more medications are being taken by the patient (polypharmacy), the higher the risk for adverse effects. Always educate your patient about possible side effects.

Appendicectomy Preoperative Intraoperative & Postoperative Nursing Care

Spread the love

Abdominal pain is most commonly caused by appendicitis, which may lead to the most frequently performed surgical procedure – Appendicectomy. While this can happen at any age, it is a common occurrence in the young.

Appendicectomy
Retrieved from http://www.crcftlauderdale.com/education/anatomy-of-the-colon.php on 9th March 2021

The appendix is a closed ended narrow tube measuring about 6mm in diameter and 7cm long. It is found in the right iliac region of the abdomen, beneath the ileocecal valve (McBurney’s point).

Appendicectomy
Retrieved from https://nadanotes.com/2018/04/07/acute-appendicitis/ on 9th March 2021

Appendicitis = Inflammation of the appendix:

  1. Acute Appendicitis
  2. Acute Appendicitis with mass
  3. Acute Appendicitis with Peritonitis
appendicitis
Retrieved from https://www.pinterest.com/pin/68117013089501104/ on 9th March 2021

Management of Appendicitis:

  • PROMPT TREATMENT: prevents morbidity and mortality
  • PREOPERATIVE CARE: supporting patient and management of symptoms
  • INTRAOPERATIVE CARE: appendicectomy
  • POSTOPERATIVE CARE: preventing complications and providing reassurance and comfort

Appendicectomy & Appendectomy = same procedure, different terminology.

Appendicectomy Preoperative Care

Apart from following the normal preoperative care techniques, an appendicectomy requires the following as well:

  • NIL BY MOUTH – no foods, drinks or oral medications should be taken as soon as decision is taken for an appendicectomy
  • IV FLUIDS ADMINISTRATION – dehydration is probable due to vomiting being a normal symptom of appendicitis
  • VITAL SIGNS MONITORING – a fever over 38.5°C may be due to the rupture of the appendix
  • NO ANALGESIA – pain needs to be monitored, not subsided, as it indicates what is happening with the appendix; regular analgesia should be administered to help the patient feel more comfortable prior to appendicectomy
  • NO HEAT – increases the risk of perforation and rupture of the appendix
  • NO LAXATIVES – induced peristalsis increases the risk of perforation and rupture of the appendix
  • VOIDING – patient should be encouraged to void if undergoing surgery for which no bowel preparation is recommended such as in appendicectomy, as avoiding incontinence during the operation leads to a lesser chance of infection

Intraoperative Negligence:

If a foreign body such as a swab is left accidentally in the patient during surgery, the patient may experience symptoms such as sepsis, localised discomfort, skin protrusion, nausea and constipation. If this goes unnoticed for a longer time, more serious complications may arise, such as abscess formation, fistulas, bowel perforation, and extreme localised pain.

To avoid such complications:

  1. count instruments and swabs during setup prior to surgery commencement
  2. count again before surgery begins
  3. count again as closure begins
  4. count again during skin closure

Pay special attention in the case of obese patients.

Appendicectomy: Open Method

Preferred method of surgery in the case of:

  • perforated appendicitis
  • peritonitis
  • history of abdominal surgery
  • paediatric patients
  • appendicular abscess

An open method appendicectomy provides good exposure, is easier to perform and straightforward. However, pelvic structures cannot be seen well, it takes longer for the patient to recover post-operation, it increases the risk of hernias and adhesions due to the weakening of the abdomen tissue by the manipulation of the bowels.

Appendicectomy: Laparoscopy

Preferred method of surgery in the case of:

  • lower complication rate
  • helps diagnose other conditions especially in women
  • preferred method for women, obese patients and athletes
  • provides better cosmetic results
  • causes less postoperative pain
  • patient can return to normal activity early

However, a laparoscopic appendicectomy takes longer to be performed, and comes at a much higher cost. Not all surgeons use this method as it requires experience. Carbon Dioxide is used to inflate the abdomen to allow surgeons to work, which may cause shoulder pain. Additionally, lack of mobilisation may lead to a needed open procedure nonetheless.

Appendicectomy
Retrieved from https://medlineplus.gov/ency/presentations/100001_3.htm on 10th March 2021

Appendicectomy Postoperative Care

If patient experiences peritonitis, antibiotics are administered IV to treat infection.

Peritonitis may develop after an appendicitis. This happens due to bacteria spread which may go unnoticed during appendicitis.

A drain may be inserted during surgery. Monitor drainage, which should decrease in time…if not, patient could be experiencing a haemorrhage.

Patient should be encouraged to mobilise as soon as possible to prevent the formation of emboli. In addition, anti-coagulants may be administered subcutaneously post-operatively, and anti-embolism stockings should be worn.

Patient may be started on food slowly only after bowel sounds can be heard, which proves good function of bowels.

Appendicectomy  peritonitis
Retrieved from https://www.pinterest.es/pin/68117013089501100/ on 9th March 2021

The patient is discharged once no fever is recorded and bowels are functioning well. Drain is removed once infection is fully resolved. Stitches are removed 7-10 days post-surgery; this can be done at a health centre. A histopathology report is later given during an outpatient visit.

No need of special diets, exercise or other lifestyle factors are required post appendicectomy.

IV Therapy Safety – Recognising Ways To Deliver Quality IV Infusion Care

Spread the love

More than 90% of hospitalised patients receive some form of IV therapy. Unfortunately, about 1/5 of patients on IV therapy experience complication or death due to lack of administration care, especially since IV medication is administered directly into the venous system. This emphasises the importance of IV therapy safety.

IV therapy safety
WHO, 2017. Medication Without Harm. Retrieved from https://www.who.int/initiatives/medication-without-harm on 7th March 2021

High Risk Medication = drugs with a high potential of significant harm to the patient if administered incorrectly eg. Potassium Chloride, Glucose (50% or more), Sodium Chloride (more than 0.9%), anticoagulants (injectable), Vitamin K, Insulin and Opiates.

Label Medication = this can be beneficial especially in the case of multiple medication syringes. Label one medication at a time whilst preparing them (do not pre-label empty syringes) and take only labelled medication near your patient to avoid mistakes. Do not administer any unattended or unlabelled medications.

Flushing = use 10ml syringe for flushing, especially in Central Line; flush with double the medication amount using a bigger than needed syringe (eg. flush 5ml using a 10ml syringe)

Peripheral Venous Cannula (PVC) Site Care:

  • use smallest cannula size possible
  • label with date and time
  • remove after 3 days
  • use transparent dressings to assess site
  • clean around cannula site using 2% Chlorhexidine in 70% Isopropyl
  • do not attempt to cannulate more than two times, if unsuccessful seek assistance
  • clean infusion equipment with Clinell (NOT an alcohol swab)
  • IMPORTANT! a cannula infection can cause sepsis and even death…remove if unnecessary, do not leave in situ just in case

Fluid Therapy: 5 R’s of Fluid Management

  1. Resuscitation
  2. Routine Maintenance
  3. Replacement
  4. Redistribution
  5. Reassessment

Fluid therapy is administered as a continuous infusion for a maximum of 24 hours followed by a review, or a bolus. Always assess for dehydration and fluid overload!

IV Line Management

  • replace IV tubings whenever cannula is changed
  • do not disconnect tubing and lines unless really necessary
  • change tubing every 96 hours

Perioperative Nursing – Preoperative Intraoperative & Postoperative Care

Spread the love

Perioperative Nursing Care

Perioperative nursing care includes:

  1. Preoperative Phase: when the patient is prepared and transferred to the theatre prior to undergoing surgery;
  2. Intraoperative Phase: during surgery and in the recovery room;
  3. Postoperative Phase: from the recovery room to the ward and until discharge, ending completely after being reviewed at the Outpatients Department.

Preoperative Nursing Care

Surgery may be required for the following reasons:

  • when further exploration is required to reach a proper diagnosis
  • as a preventative measure such as for the prevention of cancer spread
  • for treatment purposes
  • for palliative purposes such as the removal of tumors
  • for cosmetic and reconstructive purposes

PLANNED SURGERY: not an urgent requirement. It is usually scheduled weeks, months and at times years ahead.

EMERGENCY SURGERY: urgent requirement, usually performed for lifesaving purposes, as well as to stop bleeding (eg. internal bleeding) or to preserve an organ or limb (eg. in compound/open fractures where bones are protruding from the skin.

Types of surgeries:

  • Minor Surgery (eg. cyst removal or suturing)
  • Minimally Invasive (eg. infiltrations, injections)
  • Keyhole Surgery (eg. laparoscopy)
  • Major Surgery (eg. hysterectomy)

Preoperative Considerations include:

MEDICAL HISTORY: this should include information about the patient’s current health condition, known allergies, current medications list, drug abuse, past surgeries experience if any, and the identification of risk factors especially in the case of past problems with anesthesia.

PSYCHOSOCIAL STATE: evaluating the patient’s situation in relation to psychological and social wellbeing can help identify possible barriers to the recovery phase post-surgery. Reassurance can help alleviate fear, anxiety and stress pre-surgery. If needed, a patient can be referred to a social worker for additional support eg. if patient has left children behind at home, alleviating fears and concerns about their care helps reduce the person’s anxiety and stress.

EDUCATION: the patient should be provided with clear and understandable explanation with regards to what the surgery entails as well as what perioperative nursing care may be required, both verbally and in writing. The patient should also be advised about postoperative monitoring equipment which may be needed, as well as possible tubes, drains and other related equipment use in perioperative nursing care. Pain management should also be discussed with the patient in advance.

INVESTIGATION: blood tests (including CBC, urea, electrolytes and creatinine, INR or APTT and glucose), X-Rays, MRIs and CT Scans, ECG and a crossmatch (a.k.a. X-Match). Wherever possible, preoperative care should include the treatment of any existing infections, monitoring and if possible stabilising existing chronic diseases such as hypertension and diabetes, dietary deficiency and fluid and electrolyte imbalance correction, and if need be, weightloss in obese patients.

RISK FACTORS: can impact surgery success and recovery. Risk factors include age, malnutrition or obesity, pregnancy, as well as infection, diabetes, CVD, renal disease, malignancy, pulmonary disease, hepatic disease, immobility and hypovolaemia (excessive bleeding).

INFORMED CONSENT: patient signature should be acquired by the consultant prior to surgery. The nurse should make sure that information about the procedure or surgery is provided and any questions are addressed so the patient is able to give informed consent; the nurse should also make sure that informed consent has been acquired.

Preoperative Nursing Care:

  • address anxiety through communication and if needed adding music therapy, deep breathing, etc; address any body image concerns in relation to the surgery
  • nail polish should be remove so SP02 can be monitored correctly
  • bathing (4% chlorhexidine solution if patient is MRSA colonised; 2% chlorhexidine solution if undergoing a major operation; soap and water if patient is undergoing minor operation
  • shaving should be done using hair clipper so as to avoid skin abrasions, thus minimising the risk of developing a Surgical Site Infection; shaving should be done closest to the surgery time so as to avoid having enough time for bacteria from cultivating within any possible skin abrasions
  • make sure surgery site has been pre-marked by surgeon or consultant prior to being transferred to the theatre
  • keep patient warm using blankets if needed, as this will help prevent development of SSIs
  • surgical site observation
  • monitoring and documentation of patient vital signs
  • fasting and/or intake restrictions
  • possible need of medication restriction eg. drugs affecting coagulation
  • checking for dentures and loose teeth
  • bowel preparation (if needed)
  • tubes eg. nasogastric tube or urinary catheter (although these may be inserted during surgery)
  • administration of recommended pre-surgery medication eg. prophylactic antibiotics
  • completing pre-op checklist
  • if a patient with diabetes is scheduled for surgery, he should be started on the diabetic protocol since being NBM makes him prone to hypoglycaemia
  • in the case of an amputation, make sure that the leg to be amputated has been marked by the physician
  • if patient has left children behind at home, talk and empathise with the patient to help alleviate any concerns; if need be, refer to a social worker so as to ensure help will be provided during this time and during post-op period
  • if spiritual concerns are involved eg. existential problems, referring to a spiritual advisor may also help
  • if patient seems to be experiencing psychological issues in relation to surgery, referring to a psychologist may help
  • if patient is eager to know, explain the whole procedure eg. where patient is to be transferred to, what to expect right after surgery, recovery area, post-op pain management, etc.

NOTE: If patient is on Steroids pre-op for inflammation, consider that steroid side-effects include hyperglycaemia (attn. if patient is diabetic), affecting the immune system (attn. if patient is immunocompromised), and affecting the peripheral nervous system (attn. if patient has been or is being amputated or has existing issues with his arms and legs).

Transferring patient from ward to the theatre:

  1. Check patient ID
  2. Check allergy bracelet
  3. Explain procedure
  4. Ensure patient safety
  5. Provide accurate handover to the theatre nurse

Postoperative Nursing Care

This period starts right after surgeons finish the operation (an anesthetist and a theatre nurse stays with the patient after surgeon leaves), up until the 1st review after discharge as an outpatient.

Patient Assessment Right After Surgery

PULSE: monitor pulse volume and regularity

SKIN: check for any signs of cyanosis and monitor SPO2

CONSCIOUSNESS: is the patient conscious or semi-conscious? Prior to transfer to ward, patient should be fully conscious

AIRWAY: assess respiratory rate and depth

Patient Assessment In Recovery Room

  • understand and follow up on anesthetist and surgeon’s instructions
  • pain management: PCA pump if provided; prescribed medication, including PRN medication if needed
  • monitor vital signs and level of consciousness
  • assess level of pain, at rest and when ambulating; if noticing increased pain during ambulation, prophylactic pain medication may be administered pre-ambulation so as to reduce the pain and increase effectiveness of ambulation
  • monitor surgical site for bleeding and signs of infection
  • monitor input and output for urinary retention and/or for renal function indications
  • assess for signs of complications post-surgery, especially in relation to cardiovascular and pulmonary related comorbidities eg. Pneumonia (see pneumonia prevention section in link for preventative measures)
  • monitor for fluid imbalance (possible loss of fluid during surgery)
  • report any changes in patient condition and document changes
  • keep NBM for a couple of hours due to relaxed reflexes as an effect of anaesthesia
  • for diabetic patients, keep monitoring for hypoglycaemia especially whilst NBM

Patient Transfer From Theatre to Ward

Patient needs to be fully conscious and stabilised before being transferred to the ward. Monitor for any neurological impairment such as lack of movement of limbs, IV fluids and drip rate, drains, as well as same monitoring undergone in the recovery room.

Post-Surgery Investigations

  • check CBC (haemoglobin due to bleeding during and post-surgery, white cells, platelets, sodium, potassium, urea [to monitor for kidney function], creatinine and glucose [in diabetic patients, glucose status should be checked routinely])
  • X-Rays
  • MRI
  • CT Scan

Patient Care In The Ward

  • Observe IV Infusion,IV Pumps and Cannula Site
  • Assess For Nausea: patient may be administered an antiemetic drug to prevent nausea and vomiting
  • Personal Hygiene: bathing and mouth care
  • Patient Repositioning: to avoid pressure sores
  • Monitor for Confusion and Delirium
  • In case of Altered Level of Consciousness post-op, provide safety eg. side rails pulled up, personal items at reach etc
  • Monitor for Drug Allergy Symptoms
  • Patient Mobilisation: earliest possible ambulation if not contraindicated as it helps prevent complications in relation to respiration, deep vein thrombosis and pulmonary oedema; assist during ambulation
  • Encourage Deep Breathing and Coughing Exercises
  • Promote Exercise and Movement
  • Ensure Adequate Fluid Intake: start with encouraging small sips if not contraindicated
  • Wound Care: assess for infection and change dressings as required
  • Tracheostomy Care: including suctioning if present
  • Monitor for Urinary Retention: can cause restlessness, bladder distension, suprapubic discomfort and confusion; insert catheter to eliminate retention and confusion
  • If Increased Wound Bleeding is noticed, DO NOT remove the existing bandages, but apply extra pressure with another bandage on top and inform physician
