Symptoms
|
Management
|
Citrate Toxicity
|
Circumoral paraesthesia
Muscle twitching
Nausea and/or vomiting
Chills
Syncope
Tetany (rare)
Palpitations/arrhythmia
|
Avoidance:
- Warn patient of symptoms
- Oral calcium supplements before/during procedure
- Use the recommended anticoagulant solution in the correct proportions
- Slow infusion rate
Treatment:
- Stop or slow infusion
- Oral calcium supplements
- 10% calcium gluconate 5 ml slow infusion if serious reaction
|
Inadequate Citrate
|
Clotting in extracorporal circuit
DIC
Haemolysis
|
Avoidance:
- Use the recommended anticoagulation solution in the correct proportions
- Monitor:
- delivery of anticoagulant
- return IV line for clotting
- colour of plasma (red = haemolysis)
|
Heparin related
|
Bleeding
Allergy/anaphylaxis
Thrombocytopenia
|
Treatment:
- Protamine Sulphate – to reverse heparin.
- Side effects: chills, light headedness, allergy and/or anaphylaxis, dyspnoea, and/or chest pain, flushing.
|
Thrombocytopenia
|
Petechiae, Bleeding
|
Avoidance:
- Monitor platelet count 20-30% decrease expected
Treatment:
- Platelet transfusion if platelets<50 x 109/L
|
Transfusion reactions to blood and blood products
|
Allergic Anaphylaxis
|
hives, itch facial oedema, dyspnea
|
Treatment:
- Antihistamine ± hydrocortisone
|
Transfusion transmitted infection
Hepatitis B/C, HIV, CMV
ABO incompatible reaction
|
Delayed adverse reaction Haemolysis
|
- Specific to virus transmitted.
Avoidance:
- Use ABO compatible products.
Treatment:
- Stop infusion – supportive care, IV fluids – contact TMS/ Haematologist
|
Transfusion related acute lung injury
|
Severe dyspnea, hypoxia
|
- Supportive care/ICU ± hydrocortisone
|
Hypervolaemia
|
Dyspnea
Oedema
|
Avoidance:
- Monitor fluid balance – judicious use of albumin; finish with a small negative fluid balance. Must replace at least 75% of total calculated plasma volume
|
Hypovolaemia
|
Hypotension
Syncope
|
Avoidance:
- Use colloid solutions (albumin, HES etc.)
Treatment:
- Give IV fluids – colloids or normal saline
|
Abnormal electrolytes
Low calcium
Others, uncommon
|
See above
|
- Adjust composition of electrolyte solutions to correct these.
|
Hypothermia
|
Chills
|
- Use blood warmer
- Warm replacement fluids
- At risk patient groups:
- sickle cell disease
- cold haemagglutinin disease
- paraproteinaemia
- cryoglobulinaemia
- children
|
Complication of venous access
|
See previous comments
|
|
Haemolysis
|
Fever, red urine, red plasma
Renal impairment
|
Avoidance:
- Use ABO compatible blood and blood products. Monitor:
- Pressure in returning line.
- Ensure no kinking or twisting of lines and that these are fitted correctly into the machine.
- Monitor colour of plasma.
Treatment:
- Stop and resolve cause – see above
|
Air Embolus
|
Dyspnea, chest pain
|
Avoidance:
- Monitor drip chambers and returning line
Treatment:
- Procedure, turn patient onto their left side head down.
- Notify TMS/Haematologist
|
Equipment Contamination
|
Septic type
|
- Do not prime equipment more than 1 hour before the procedure.
|
Bacterial contamination
|
Septic shock
|
Avoidance:
- Inspect all replacement fluids to ensure no evidence of microbial contamination or defects in the container.
Treatment:
- Stop procedure, call TMS/Haematologist.
- Give IV fluids to maintain BP.
- Administer IV antibiotics.
