Total Parenteral Nutrition – Indications & Complications & Nursing Care

Spread the love

Total parenteral nutrition can provide an individual with the necessary nutritional support and provision of therapeutic nutrients to maintain or restore optimal nutrition status and health. Total Parenteral Nutrition bypasses the digestive system by dripping a nutritionally adequate hypertonic solution containing glucose, protein, hydrolysates, minerals and vitramins directly into the venous system through an indwelling catheter into the superior vena cava or another main vein.

Total Parenteral Nutrition Contents

MACRO-NUTRIENTS:

  • Carbohydrates (glucose)
  • Proteins (amino acids)
  • Lipids (fatty acids)

OTHERS:

  • Electrolytes

TPN Bag consisting of Macro-Nutrients + Electrolytes – Retrieved from https://www.mims.com/hongkong/drug/info/olimel%20n9e-periolimel%20n4e?type=full on 2nd June 2021

MICRO-NUTRIENTS:

  • Multi-Vitamins (eg. Vitamin B)
  • Trace Elements/Minerals (eg. Selenium & Manganese)

A bag of TPN provides the patient with about 2270kcal nutritional intake. This high calorie intake is not considered to be too much since patients on TPN are usually fighting inflammation, requiring wound healing etc.

Indications for Total Parenteral Nutrition

Total Parenteral Nutrition is indicated for patients who:

  • are lacking nutritional requirements (commonly related to health-related conditions)
  • have documented inadequate oral intake (common indication in the elderly)
  • experience an unpredictable return of their GI function (eg. malabsorption leading to lack of good nutritional outcome)
  • are on a prolonged nil-by-mouth period (eg. patients undergoing GI surgery)

DIGESTIVE DISORDERS:

  • GI fistulae
  • major GI surgery
  • uncontrolled malabsorption (eg. in Chron’s Disease)
  • short bowel syndrome (gastroschisis, volvulus & necrotising enterocolitis)
  • severe enteropathy (genetic-related issues such as microvillus atrophy, tufting enteropathy, congenital, auto-immune)
  • dysmotility or pseudo-obstruction
  • severe acute pancreatitis

NON-DIGESTIVE DISORDERS:

  • post-chemotherapy
  • radiotherapy
  • severe mucositis
  • bone marrow transplant
  • multi-organ failure in extensive trauma and burns
  • immature gut

Contraindications for Total Parenteral Nutrition

  • functioning GI tract (if the problem is with the upper GI tract and the lower GI tract is fully functioning, enteral feeding directly into the jenunum would be recommended)
  • need for <5 days of TPN with no severe malnutrition
  • difficulty in obtaining venous access
  • poor prognosis that doesn’t warrant aggressive nutritional support
  • if risks outweigh the benefits

TPN and CVCs Complications

  • catheter and systemic infections
  • catheter obstruction eg. blocked lumens
  • pneumothorax (may happen during catheter insertion)
  • thrombosis (may happen during catheter insertion)
  • bone disease
  • hepatobiliary disease (eg. TPN-induced liver failure due to the nutritional infusion being administered directly into the venous system)
  • renal disease

Patient Monitoring

  • vital signs (temperature to monitor for sepsis; blood glucose monitoring due to TPN containing 40% glucose)
  • intake & output
  • weight (especially malnourished patients)
  • fluid requirements
  • patient complaints
  • CVC exit site (monitor for signs of inflammation)
  • overall clinical status
  • blood (renal: U&E, Mg, Ca, Phos, Cr; heamat: CBC, INR; liver function: Alk Phos, Bil.; Glucose and Lipid, Iron and Ferritin; Albumin)
  • MRSA nasal swabbing (if patient is colonised with MRSA, treatment is required prior to developing into an infection)

TPN Bag Changing Technique

  1. use an aseptic non-touch technique
  2. hand hygiene
  3. don apron
  4. clean work surface with 70% alcohol and let dry
  5. cover with sterile drape
  6. place all sterile items on it: sterile IVI tubing, syringe and needle
  7. other needed items should be placed in a cleaned tray
  8. apply alcohol handrub
  9. don gloves
  10. switch off volumetric pump
  11. disconnect previous TPN line from the needleless valve attached to the central venous catheter
  12. mix the 3 compartments of the new TPN bag and hang on drip stand – DO NOT TOUCH CONNECTION PARTS
  13. disinfect the needleless valve with 2% chlorhexidine in 70% alcohol and leave to dry
  14. spike TPN bag with infusion line and prime whilst still capped
  15. remove cap and connect to patient through the needleless valve
  16. add additives Additrace and Cernevit to the TPN bag from the injectable port using an aseptic non-touch technique
  17. dispose of materials appropriately

Peripheral Vascular Access – Sites, Indications & Contraindications

Spread the love

Peripheral vascular access is commonly sought through the non-dominant upper extremity due to a reduced risk of dislodgement, thrombosis and thrombophlebitis. However, peripheral venous line cannulation can be done successfully through various sites in the body.

Peripheral Vascular Access Sites

Upper Extremity: The metacarpal veins on the dorsum of the hand drain proximally through the dorsal venous arch into the cephalic and basilic veins in the forearm. These connect by the median cubital and median antebrachial veins in the antecubital fossa region, prior to continuing up the arm.

Lower Extremity: lines may be placed from the dorsal venous plexus of the foot which become the great and small saphenous veins in the leg.

Scalp: may be appropriate in neonates or infants. Sites include the frontal, occipital, superficial temporal or posterior auricular veins.

Retrieved from https://www.researchgate.net/figure/Simplified-schematic-of-the-arterial-supply-of-the-skull-lateral-view-Vessels_fig2_328171256 on 1st June 2021

Preferred veins for cannulation are straight, distal and non-branched (since venous valves are usually located close to branching points). When accessing a vein, a tourniquet is to be placed proximally to the site to create engorgement in the vein. Vein should feel spongy and should not pulsate on palpation (indication of an artery rather than a vein). Avoid veins that are hard to the touch due to possible thrombosis.

Indications for Peripheral Vascular Access

  • administration of IV medications
  • administration of IV fluids
  • phlebotomy (prior to medication and/or fluids to avoid dilution or contamination of blood samples)

Contraindications for Peripheral Vascular Access

While there are no absolute contraindications for cannulation, there are relative contraindications for which clinical judgement on benefits and risks of procedure is warranted. These include:

  • coagulopathy
  • local infection
  • burns
  • compromised skin at planned insertion site
  • previous lymphatic nodal clearance
  • arteriovenous fistula formation
  • deep vein thrombosis

In the case of extended treatment, it is best to opt for a central venous catheter rather than peripheral vascular access, as this offers lower failure rates in relation to long-term use.

Optimum PVA Outcome

  • prompt placement of peripheral vascular access when required
  • regular monitoring of line function
  • consideration regarding need for venous access
  • removal of lines when no longer indicated
  • early intervention in the case of complications

Chemotherapy Administration

Spread the love

Cancer is a disease in which some body cells start to divide rapidly, leading to a spread to other parts of the body. Tumour cells tend to grow in a much more rapid way than normal cells. Chemotherapy administration stops this cell division process by killing them.

Chemotherapy administration routes include oral, subcutaneous, intramuscular, intravenous, intrathecal (into the spinal fluid) , intravesical (into the bladder to treat bladder cancer) and topical (eg. in melanoma).

A Chemotherapy Treatment Chart includes:

  • chemotherapy name
  • dosage
  • route
  • date and time for each chemotherapy administration (be it on the same day or on different days)
  • patient details
  • medications to be administered along with chemotherapy eg. antiemetics to counteract nausea caused by chemotherapy
  • signature, name or initials of medical officer prescription in chemotherapy administration chart
Excerpt from a Chemotherapy Protocol – Retrieved from http://nssg.oxford-haematology.org.uk/lymphoma/documents/lymphoma-chemo-protocols/L-80-r-chop-21.pdf on 31st May 2021

In reference to the above protocol excerpt:

  • R-CHOP-21 is the name of the protocol
  • The letters RCHOP refer to the chemotherapies being administered
  • P is referring to Prednisolone
  • 21 refers to the number of days per chemotherapy cycle
  • The protocol outlines all details related to the chemotherapies being administered and how all medications should be administered to one specific patient

Prior To Chemotherapy Administration

  1. Medical assessment needs to be carried out and documented on file (patient has to be deemed fit for chemotherapy prior to treatment start)
  2. Parameters as well as height and weight need to be taken as baseline (patient shouldn’t be given when or if patient is severely unwell, as chemotherapy worsens patient condition)
  3. Informed consent should be acquired from the patient and placed in file
  4. Routine tests such as blood tests, allergies and pregnancy result should be acquired and checked by the medical officer
  5. Re-discuss side effects with patient
  6. Get chemotherapy from designated locations

First Check – Prior to Chemotherapy Administration

  • Patient identity details
  • Name of Chemotherapy
  • Dose of Chemotherapy
  • Route of administration
  • Date and Time of administration
  • Chemotherapy drugs sequence
  • Duration of infusion
  • Rate of administration
  • Pharmacist signature
  • Expiry date and time
  • Uncompromised integrity of chemotherapy bag
  • Known drug allergies
  • Protect from light if required

With reference to the above, the information on the chemotherapy treatment chart and the chemotherapy plastic bag must be compared and matched. Check should be carried out independently by two different nurses at the patient’s side immediately prior to administration.

Second Check – Prior to Chemotherapy Administration

  • Patient identity details
  • Name of chemotherapy
  • Chemotherapy dose and volume
  • Route of administration
  • Date and Time of administration
  • Expiry date and time
  • Pharmacist signature
  • Check for precipitation in chemotherapy container

With reference to the above, the information on the chemotherapy plastic bag and the chemotherapy container inside must be compared and matched. Check should be carried out independently by two different nurses at the patient’s side immediately prior to administration.

Third Check – Prior to Chemotherapy Administration

  • Patient identity details
  • Known drug allergies

With reference to the above, the information on the chemotherapy container must be checked with patient. Check is usually carried out by the nurse administering the chemotherapy.

Once all checks are performed, the two nurses sign on the treatment chart, indicating that the chemotherapy administration can be started.

Preparation – Prior to Chemotherapy Administration

  • Anaphylactic reaction/shock tray (Hydrocortisone, Chlorphenamine – antihistamine, Ventolin for bronchospasms, flushes, oxygen masks etc.)
  • CPR trolley
  • Emergency call bell
  • Hypersensitivity tray
  • Extravasation kit
  • Hot and Cold pack
  • Chemotherapy spillage kit
  • Emergency shower

Oral Chemotherapy

  • compliance with prescribed drug schedule
  • check dietary requirements in relation to oral drug administration
  • handle with gloves
  • do NOT crush chemotherapy tablets/capsules

Drug Administration

  • Administer chemotherapy preferably via a central line
  • If a cannula is being used (eg. if chemotherapy needs to be administered urgently), insert cannula immediately before chemotherapy administration in large veins in the upper limbs (use either the pink or the blue cannulas for chemotherapy administration); chemotherapy should NOT be administered via cannulas in the lower limbs or over bony prominences or in small veins
  • Avoid repeated punctures to the same vein during the same venepuncture session as this increases the risk of extravasation
  • Use clear dressing over insertion site to see any leakages immediately (do not use bandages or occlusive dressings)
  • Tell patient to report immediately any signs or symptoms such as stinging, burning sensation, tenderness, pain or any other sensation at the infusion site
  • Check for venous return (back-flow) prior to chemotherapy administration

Personal Protective Equipment

  • gloves (one set of gloves is enough)
  • use double gloving only in the case of chemotherapy spillage or topical application of chemotherapy
  • cover cuts and scratches with waterproof dressing to avoid infiltration of the skin by chemotherapy
  • gloves should be worn at all times when in contact with bodily fluids from patient receiving chemotherapy
  • plastic apron or if available, gown during chemotherapy administration
  • gown should be used in the case of chemotherapy spillage
  • goggles or full face visor should be used when dealing with spillages (if chemotherapy is splashed into eyes, rinse continuously with cold running water for 10-20 minutes and seek medical advice)
  • masks should be worn in chemotherapy spillage event
  • shoe covers should be worn for spillage management
  • handle chemotherapy below waist level to avoid spillages on face
  • pregnant nurses should avoid administering chemotherapy
  • items that come into contact with chemotherapy should be discarded into the appropriate chemotherapy waste bins

Chemotherapy cannot be cleaned by alcohol handrub…use soap and water instead.

In the case of Extravasation…

  1. STOP infusion and DISCONNECT tubing
  2. WITHDRAW as much drug from cannula or central line as possible
  3. DO NOT FLUSH!
  4. Inform medical officer
  5. Open extravasation kit
Extravasation – Retrieved from https://www.pinterest.com/pin/504966176945168896/ on 1st June 2021

In the case of Hypersensitivity Reaction…

Hypersensitivity reaction manifests as uticaria, bronchospasm, rash, abdomen cramping and hypotension, usually with treatments such as Rituximab. If the patient has a high risk of hypersensitivity reaction, premedication is given as steroids and antihistamines.

Central Venous Access Devices – CVCs & PICC Line Insertion & Care

Spread the love

Central Venous Access Devices (CVAD) are catheters inserted into a vein through the venous system, which are then advanced to the lower third of the superior vena cava, which has a higher blood flow than any other peripheral vein. This allows irritant drugs and fluids to get diluted quickly, thus avoiding damage to the vein.

Central Venous Access Devices
Retrieved from https://edu.cdhb.health.nz/Hospitals-Services/Health-Professionals/pdu/Documents/CENTRAL%20VENOUS%20ACCESS%20DEVICE%20%20Resource%20Book%202011.pdf on 30th May 2021

A Central Venous Access Device is a central venous catheter which is inserted either through a peripheral vein (PICC Line) or through a proximal central vein, usuall through the internal jugular vein, subclavian vein or femoral vein (CVC).

A CVAD is inserted using a sterile technique in a theatre setting.

Central Venous Access Devices
Retrieved from https://globalmedikit.in/product/triple-lumen-central-venous-catheter-set-seldinger-technique/ on 30th May 2021

Indications for Central Venous Access Devices

ACCESS FOR DRUGS:

  • irritant drug infusion (eg. Chemotherapy & Total Parenteral Nutrition)
  • poor peripheral access (eg. patient is experiencing a hypovolaemic shock)
  • long term drug administration (eg. IV antibiotic treatment for weeks)

ACCESS FOR EXTRACORPOREAL BLOOD CIRCUITS:

  • renal placement therapy (dialysis)
  • plasma exchange

Both of the above are high-flow procedures for which peripheral venous access cannot be chosen.

ACCESS FOR INTERVENTION MONITORING:

  • central venous pressure
  • central venous O2 saturation
  • pulmonary artery pressure
  • temporary transvenous pacing
  • targeted temperature management
  • frequent blood sampling

Central Venous Access Devices Contraindications

  • site trauma
  • site infection
  • vein thrombosis or stenosis (narrowing)
  • coagulopathy (impaired ability to clot blood, leading to increased risk of bleeding) and thrombocytopaenia (decreased number of platelets in blood, leading to increased risk of bleeding)
  • vessel haemorrhage
  • proximal vascular injury eg. blunt or penetrating injury on site

CVAD Classification

  1. Site (jugular or subclavian or femoral or brachial)
  2. Lumens (single or double or triple or quad)
  3. Time (short term or mid term or long term)
  4. Type (central or peripheral)
  5. Tunnelling (tunnelled or non-tunnelled <6 weeks or totally implantable port-a-cath for years)

Central Venous Catheter Insertion

  • May be inserted under ultrasound directed technique
  • Inserted by an anaesthetist in a theatre setting
  • Anatomical landmarks can be used in emergency situations
  • Trendelburg position (supine with head declined) is used during procedure to avoid air embolus

CVC (central venous catheter) is inserted through the internal jugular vein, subclavian vein or femoral vein.

PICC (peripherally inserted central catheter) is inserted through a peripheral vein eg. basilic vein or cephalic vein.

Protective Measures and Protective Equipment for Insertion

Sterility and an aseptic technique with PPEs including sterile gown, sterile gloves and sterile drape. In case of increased risk of contact with blood or body fluids, eye and/or full protection should be used.

2% Chlorhexidine Gluconate in 70% Isopropyl alcohol should be used and allowed to dry (in case of patient sensitivity use Povidone-Iodine instead).

Dressing used should be sterile, semi-permeable and transparent to allow insertion site observation.

Blood is aspirated from all lumens to confirm lumen patency.

Chest x-ray is to be performed prior to use so as to rule out pneumothorax and confirm correct placement.

Central Venous Access Devices
Retrieved from https://www.ausmed.com/cpd/articles/-central-venous-catheters on 30th May 2021

Central Venous Access Devices Tip Placement

  • CVAD position must be verified through an x-ray prior to use
  • CVC distal tip inserted into the upper body must be placed in the cavoatrial junction (the point in which the superior vena cava meets the right atrium)
  • CVC distal tip inserted through the femoral vein must be placed in the inferior vena cava right above the diaphragm level
  • PICC line distal tip inserted into a peripheral vein must be placed resting in the superior vena cava

Incorrect catheter tip placement increases the risk of mechanical and thrombotic complications. Tip positioning depends on the indications for catheterisation and the chosen site of insertion in the patient.

CVC Care

  • Use an aseptic technique for CVC care
  • Needleless injection ports must be changed once a week
  • Catheter site must be cleaned at least once a week using 2% chlorhexidine in 70% alcohol unless visibly soiled
  • Ports should be cleaned with 2% chlorhexidine in 70% alcohol prior to use
  • Use a gauze dressing if entry site is bleeding or oozing until resolved; otherwise use a transparent semi-permeable dressing for easy observation of entry site
  • Push-pause technique with 0.9% saline in a 10ml syringe is recommended for flushing of lumens, as this technique creates turbulence and allows the flushing of any debris in the lumens
  • Apply positive pressure (hold plunger down) when disconnecting syringe to avoid air entering the catheter
  • Apply central line dressing using aseptic technique; Use a sterile dressing pack and sterile gloves (since you’re accessing entry site); Disinfect skin with 2% Chlorhexidine in 70% Alcohol foam; Write date of dressing change on dressing
  • Replace administration set immediately after blood products administration; after 24 hours after total parenteral nutrition containing lipids; otherwise within 72 hours
  • Remove catheter if no longer required

CVC Blood Sampling

CVC blood sampling must be performed using a Vacutainer via a needleless injection cap to maintain a closed system and prevent being contaminated with patient blood. Following blood sampling from a CVC, flush using at least 20ml 0.9% sodium chloride using a 10ml and another 10ml syringe.

CVAD Care in the Community

Patient family members may be required to care for a CVAD within the community setting. Teaching correct procedures is crucial in avoiding unnecessary infections.

  • Change dressing weekly unless soiled or not intact, cleaning insertion site with 2% chlorhexidine in 70% alcohol prior to dressing change
  • Aspirate and flush lumens weekly if not regularly used
  • Take a shower, not a bath, to reduce infection risk
  • Swimming (submerging of CVC) is not recommended
  • Avoid vigorous physical activity so as not to dislodge CVC
  • Implanted ports require no such restrictions

CVC Complications

DELAYED: central line dysfunction and/or infection

IMMEDIATE: vascular, cardiac and/or pulmonary

INFECTIOUS : sepsis (widespread infection) and/or site infection

EMBOLIC: thrombosis (eg. air embolus)

MECHANICAL: dislodgement, incorrect plaement, catheter damage and/or catheter migration

If occlusion within the catheter is noted, ask patient to cough and take deep breaths and raise arm over head, as occlusion can be a positional issue.

Central Venous Catheter Blood Stream Infection (CVCBSI)

A CLABSI (central line associated bloodstream infection) is an infection that develops within 48 hours of a central line insertion, which is unrelated to any other infection site.

EXTRALUMINAL COLONISATION – originating from skin insertion site, commonly occurring in non-tunnelled CVCs

INTRALUMINAL COLONISATION – originating from catheter hub, commonly occurring in long-term lines eg. tunnelled CVCs

HEMATOGENOUSLY COLONISED – originating from a distant infection site

Phlebotomy – Withdrawing Venous Blood for Blood Testing Purposes

Spread the love

Phlebotomy is the introduction of a needle into a vein to withdraw a sample of blood for haematology (to assess blood cell composition eg. Complete Blood Count CBC), biochemistry (to assess electrolytes) or bacteriology (blood cultures) reasons.

Venepuncture is a highly invasive common diagnostic advanced skill regulated by institutional or ward protocols.

Blood investigations are required for:

  • evaluating treatment progress
  • screening for specific diseases
  • ensuring that a drug is within its therapeutic level (eg. checking digoxin levels to prevent digoxin toxicity)
  • checking for the patient’s wellbeing

Venepuncture Preferred Sites:

  • Basilic Vein
  • Cephalic Vein
  • Medial-Cubital Vein

The basilic vein on the dorsum of the hand can also be accessed, whilst foot veins should be accessed only as a last resort.

AVOID:

  • amputation, mastectomy or lymphoedema sides
  • fractured limb
  • paralysis sides
  • AV graft or fistula
  • IV infusion sites
  • frequently used areas for venepuncture

DO NOT USE:

  • pulsating vessels (they are probably arteries)
  • haematoma
  • oedema
  • inflammation or infection
  • fibrous veins (rigid, cordlike veins that roll)

Factors Influencing Venous Circulation

  • VASOCONSTRICTION – anxiety, stress, shock, cold
  • VASODILATION – warm, mechanical irritation, chemical irritation
  • BLOOD PRESSURE DROP
  • THROMBOSIS
  • LOW IV COMPONENT – dehydration, haemorrhage

Phlebotomy Procedure

Equipment Needed for Venepuncture

  • tourniquet
  • alcohol swabs
  • non-sterile gloves
  • vacutainer OR syringe & needle
  • blood sample bottles
  • sharps container
  • gauze swab
  • adhesive dressing

Nurse Safety Procedures:

  • hand hygiene
  • gloves
  • dispose of used items correctly
  • handle needles safely
  • dispose of needles in the sharps box

Patient Safety Procedures:

  • confirm patient identity
  • perform skill only if needed
  • cross-contamination prevention
  • disinfect skin

In the case of difficult venous access:

  • tap gently onto the vein
  • put arm in warm water to encourage vasodilation
  • lower arm below the level of the heart
  • ask for assistance
  • use advanced imaging techniques

NOTES:

When taking blood, mix sample bottle between 8-10 times after withdrawal.

Bleeding following venepuncture can take up to 10 minutes to stop, thus, tell patient to apply pressure to avoid haematoma formation.

Phlebotomy Problems:

ARTERIAL STAB:

  1. immediately remove needle
  2. apply firm pressure and elevate for more than 5 minutes until bleeding stops
  3. assess movement, sensation and circulation of affected limb
  4. consult physician

NERVE DAMAGE:

  1. immediately remove needle
  2. examine movement, sensation and circulation of affected limb
  3. consult physician

HAEMATOMA PREVENTION:

  1. insert needle at correct angle to avoid opposite vein wall perforation
  2. hold vacutainer and needle steadily whilst taking blood
  3. remove tourniquet prior to removing needle
  4. apply pressure on puncture site immediately following needle removal

Administration of Blood and Blood Components

Spread the love

Administration of blood and blood components can be indicated to restore blood volume where there is inadequate tissue perfusion, to replace platelets, coagulation factors and other plasma proteins, as well as to increase the haemoglobin concentration and the blood oxygen carrying capacity.

Administration of blood and blood components
Retrieved from https://stanfordbloodcenter.org/should-you-be-donating-platelets/ on 29th April 2021

Red Cell Concentrates – indicated for anaemia and acute blood loss: help increase oxygen carrying capacity through raising haemoglobin concentration in the patient. Can be stored in a temperature of 4 +/-2°C for 42 days (or for 28 days if irradiated). If unused or left for more than 30 minutes in the transport box, Red Cell Concentrates should be returned to the Blood Bank to minimise the risk of bacterial growth.

Fresh Frozen Plasma – indicated for warfarin reversal in a bleeding patient, in DIC (Disseminated Intravascular Coagulation) in a bleeding patient, or in Thrombotic Thrombocytopenia Purpura during plasma exchange. Can be stored in a temperature of less than -25°C for 3 years; must be used by 6 hours following thawing if stored in the blood transport box.

Platelets – indicated for massive haemorrhage / DIC, acute leukaemia, lumbar puncture, gastroscopy, biopsy, liver biopsy, laparatomy and eye operations: help prevent and/or treat haemorrhage in patients with Thrombocytopenia or Platelet Function Defect. Can be stored in a temperature of 22 +/-2°C for 5 days in an agitator. Platelets should be transfused immediately…they should NOT be stored outside the Blood Bank.

Prior to blood units being collected from the Hospital Blood Bank, patient must be ready to be transfused: WEARING ID band; HAVING patent IV access; RECORDING of patient baseline observations.

Blood should be collected in the appropriate transport boxes with the necessary ice pack and separator. Platelets should NOT be packed with ice packs.

Collection should be done only when providing a legibly filled out Blood Issue Form.

Once collected, blood component should be delivered without delay to the responsible healthcare professional.

Procedure for Administration of Blood Products & Blood Components

  1. Decision – potential risks and benefits as well as alternatives to blood transfusion should be considered during discussion between the doctor and patient. Information should be given so the patient can make an informed decision (leaflet should also be given to the patient or relatives prior to transfusion).
  2. Prescription – blood components can only be prescribed by a medical practitioner.
  3. Collection – prescribed blood components should be picked up from the HBB (Hospital Blood Bank) ONLY when the patient is ready to be transfused (See Collection of Blood Units from HBB)
  4. Inspection – check expiry date, integrity of pack, discolouration or haemolysis, and that platelet pack does not show clumps or looks cloudy. Transfusion should be started immediately after being collected from HBB. DO NOT STORE in medicine fridges!
  5. Transfusion – only qualified healthcare professionals with transfusion training can transfuse blood components. Procedure must be performed by 2 healthcare professionals, both of who need to sign the Nurses Record – Blood Product Transfusion Form. Overnight transfusions should be avoided unless absolutely necessary. Blood components should be gently mixed prior to administration. The blood administration set used for transfusion should contain an integral clot filter for all blood components (170-200 µm -micrometer). Blood administration set should be primed with the blood component or 0.9% normal saline. Platelets should NOT be transfused through an administration set which has already been used for blood transfusion. DO NOT flush out the blood in the administration line once transfusion is finished.
  6. Administration Rate RCC should be transfused over 90-120 minutes (less tolerant patients should be transfused at a slower rate with extra monitoring, not exceeding 4 hours of transfusion); Platelets should be administered over 30-60 minutes immediately following availability; Plasma should be infused at a rate of 10-20ml/kg/hr, not exceeding 4 hours of transfusion.
  7. Note – administration set should be changed at least every 12 hours in RCC and FFP transfusion. Transfusion completion should happen within 4 hours following removal from temperature controlled storage. RCC and FFP exposed to temperatures of over 40° may cause a severe transfusion reaction.
  8. End of Transfusion – wear gloves and remove empty blood bag and administration set (change set if infusion is to be continued); flush the cannula, document observations; fill in Traceability Form and send to HBB; dispose of blood administration set and bag in a yellow bag (clinical waste).

Patient Observation During Transfusion

  • Patient should be monitored by regular visual observations which should also be documented, throughout the transfusion phase of each transfused unit.
  • Record baseline observations of temperature, pulse, respiration and blood pressure prior to transfusion, 15 minutes into the transfusion and at the end of the transfusion plus more if needed.
  • Transfusion reaction signs include: fever, nausea, respiratory distress, back/flank or IV site pain, skin changes, uticaria, diarrhoea, shaking, headache, hypo/hypertension, chest pain, urine colour changes, tachycardia, oliguria, jaundice, unusual feelings.
  • Acute transfusion reactions include Acute Haemolytic Transfusion Reactions, Febrile Non-Haemolytic Transfusion Reactions FNHTR (mild or moderate fever, chills or rigors without any other known cause – if patient is otherwise stable administer paracetamol and restart transfusion at a slower rate), Acute Allergic & Anaphylactic Transfusion Reaction, Transfusion Associated Circulatory Overload (TACO), Transfusion Related Acute Lune Injury (TRALI) and Hypotensive Transfusion Reaction.
  • Delayed transfusion reactions include Delayed Haemolytic Transfusion Reaction, Transfusion-Associated Graft-Versus-Host Disease, Post Transfusion Purpura and Transfusion Transmitted Infection.
  • If transfusion reaction is suspected STOP/PAUSE immediately; report reaction to nursing officer, medical officer and the Blood Bank; assess airway, breathing and circulation and if need be call for resuscitation team; maintain venous access through slow normal saline administration; record observations (temperature, pulse, RR, BP, SPO2 and Urinary Output); if patient experiences temperature rise of <1.5°C, transfusion can be paused so patient can be administered necessary medication, and later on if symptoms subside can be restarted on transfusion.
  • Document reaction time, signs and symptoms, name of consulted physician, treatment and patient response, and plan.

The law stipulates that “Member States shall ensure that blood establishments, hospital blood banks, or facilities retain the data for at least 30 years in an appropriate and readable storage medium in order to ensure traceability” – Directive 2005/61/EC

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
  • Monitor ABC’s (Airway, Breathing, Circulation)
  • 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
  • do not discard syringe…keep for further investigation
  • monitor vital signs
  • provide reassurance
  • perform CPR or administer Oxygen if required

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)

Retrieved from https://www.nursingtimes.net/clinical-archive/medicine-management/how-to-calculate-drug-doses-and-infusion-rates-accurately-16-10-2017/ on 20th March 2021
Retrieved from https://www.pinterest.com/pin/AT0jj4KssO4ZYz_XPFSR0ecqpZFz5MQdVud_EtbkgM3p9oWpV4APsmk/ on 20th March 2021

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

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
Accessed from https://www.pinterest.com/pin/AducalWbg8Y2seyS3UYT1lIUzDEoUNEebnW8ArPfuuTWJ6f4ygco7VM/ on 7th March 2021

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
