Safe Transfusion Flashcards
Universal donar
O negative
Universal recipient
AB positive
Why can O blood be given safely to all groups in a life threatening situtation
There are no A or B antigens to react with the recipients antibodies
Incompatible ABO group reactions
Massive immune response leading to:
shock and Disseminated Intravascular coagulation.
Death from: circulatory collapse, severe bleeding or renal failure within minutes or hours
What legislation governs transfusion documentation
UK Blood Safety and Quality Regulations
Decision to transfuse must be recorded in the case note
record of administration of each blood component
proof of fate of components whether transfused or discarded
Why shouldn’t you prime an administration set with Dextrose or Ringers Lactate
Can cause haemolyis or lead to clotting of transfused components
Why cant platelets be administered through a set previously used for red cells or other components
Could cause aggregation of cells
Why should administration sets have mesh filter
to remove mircoraggregates
What documented MUST be completed for each component transfused
Donor number
date and time of transfusion
Signature of persons undertaking checking procedure
should be completed on traceability and hospital transfusion documentation
Details of transfusion must be included
IF blood component not transfused must inform HTL so that full traceability maintained
Signs and symptoms of mild transfusion reaction
Pyrexia
Signs and symptoms of severe transfusion reacton
Pyrexia, rigors (shivering) Hypotension Loin/Back pan increasing anxiety pain at infusion site respiratory distress dark urine severe tachycardia unexpected bleeding DIC) late stage
Management of Severe Transfusion Reaction
1.STOP the transfusion
Replace admin set, maintain IV access with normal saline to maintain systolic BP,check patient and component compatibility)
- Call doctor to see patient urgently..
- Assess patient (Check urine for signs of hameoglobinuria, commence appropriate treatment; Maintain airway, give high flow O2, administer adrenaline and/or diuretic and resuscitate
- Inform HTL and return component
- Document event in patient notes
Management of mild transfusion reaction
Stop transfusion (check patient and component compatibility)
Seek medical advice
Assess patient
Commence appropriate treatment
If signs and symptoms worsen within 15 minutes treat as severe reaction
Haemolytic transfusion reaction
Rare type of transfusion reaction usually seen in patient who have developed red cell antibodies from a past transfusion or pregnancy.
Symptoms occur days after the transfusion suggesting that cells are being destroyed abnormally quickly
fever
falling Hb or a rise in Hb less than expected
jaundice
haemoglobinuria (black wee wee)
Hazards of transfusion?
Administration of wrong blood
Wrong blood in tube
Inappropriate or unnecessary blood transfusion
Handling and storage errors (biggest source)
Lab errors
