slide-10
SLIDE 10

Mild Transfusion Reaction

 Fever > 38⁰C and rise 1-2 ⁰ from baseline and/or

pruritis or rash but with no other features

 Management:

 Restart transfusion, paracetamol if febrile, anti-

histamine for rash, slow rate of transfusion

 Careful observation

slide-11
SLIDE 11

Severe Transfusion Reaction

  • What is the differential diagnosis?
  • Acute Haemolytic Transfusion Reaction
  • Anaphylaxis
  • TACO
  • TRALI
  • Bacterial contamination
slide-12
SLIDE 12

Management of severe reaction

 Stop transfusion, disconnect giving set, administer IV NaCl 0.9%  Check ABC  High flow O2 if dyspnoeic  If wheeze: salbutamol nebuliser  If hypotensive; lie flat and elevate legs  Consider the diagnosis and treat accordingly

slide-13
SLIDE 13

Scenario 3

 26 year old man post splenectomy, RTA  Hb 7.3 postoperatively. Prescribed 2 units RCC  5 minutes into 1st unit RCC:  BP 80/40, HR 100, SpO2 85%, RR 24, Temp 36.5  O/E: critically unwell, wheeze, stridor, generalised rash

slide-14
SLIDE 14

Shock/Hypotension with evidence of Anaphylaxis:

 ABC  IM Adrenaline 0.5 ml of 1:1000 (repeated if necessary)  Rapid fluid resusitation (crystalloid)  IV Chlorpheniramine 10 mg  IV Hydrocortisone 200 mg  Inhaled/IV Salbutamol

slide-15
SLIDE 15

Scenario 4

 77 year old lady admitted with #NOF Hb 7.1  1 hour into 2nd unit RCC, becomes unwell, short of breath  BP 124/80, HR 95, RR 28, SpO2 80%, Temp 36.9  O/E: no signs of anaphylaxis, crackles throughout both lung fields,

JVP elevated

 What is your differential diagnosis?

slide-16
SLIDE 16

Severe dyspnoea without shock

 Differential Diagnosis:

 TACO (Transfusion associated circulatory overload)  TRALI (Transfusion associated acute lung injury)

 Management:

 Discontinue transfusion, high flow O2, urgent Chest X-Ray  TACO: Diuresis  TRALI: Ventilatory support

slide-17
SLIDE 17

Scenario 5

 55 year old lady day 2 post right hemicolectomy for CRC  Hb 7.1, prescribed 2 units RCC by SROC  1st unit transfused uneventfully  2nd unit commenced:  After 5 minutes; complains of new flank pain, fever  Call to SIOC: “Temp is 39.1, should we stop the transfusion? Do you

want to take blood cultures?”

slide-18
SLIDE 18

Scenario 5

 SIOC attends immediately  Patient acutely distressed, diaphoretic, bleeding from surgical

wound and IVC site, urine reddish brown

 BP 90/50, HR 109, Temp 39.1, SpO2 96%, RR 18  What do you do?  What is the differential diagnosis?

slide-19
SLIDE 19

Shock/Hypotension with no evidence

  • f overload or anaphylaxis

 Differential Diagnosis:

 Acute Haemolysis (ABO incompatibility)  Bacterial contamination (sepsis)

 Management:

 Discontinue transfusion and manage as per all severe reactions  If ABO incompatible, contact lab immediately  If bacterial contamination suspected; take blood cultures and start

Piperacillin/Tazobactam and Gentamicin

A quick word on platelets…

slide-21
SLIDE 21

What is a bag of platelets

 “pool” of platelets:

a preparation of platelets derived from 4 units of whole blood,

  • ie. 4 donors

 Apheresis platelets:

single donor platelets, collected specifically from a platelet donor at the IBTS

slide-22
SLIDE 22

Platelet practicalities

 One unit of platelets (pooled or apheresis) is sufficient for one Adult

Therapeutic Dose (ATD)

 One ATD should increase the platelet count by 20-40 x 109/L  Platelet shelf life: 5 days, at room temp (22 degrees), on an agitator

slide-23
SLIDE 23

Platelet practicalities

 Platelets are always in very high demand; be sensible  All platelets must come from IBTS in Dublin. NONE stored in Cork  Cost of one pool of platelets: € 826  If platelets are ordered and subsequently they are not actually

required/clinical scenario changes:

 Contact the blood bank immediately as these platelets could be

used for transfusion to a different patient

slide-24
SLIDE 24

Indications for platelet transfusion

 Prophylactic

1.

Prevent spontaneous bleeding

2.

Prior to an invasive procedure

 Therapeutic; in active bleeding

slide-25
SLIDE 25

Prophylactic Transfusion

Indication Target Platelet Count Stable patient 10 x 109/L Febrile patient 20 x 109/L Prior to invasive procedure 50 x 109/L Prior to invasive procedure at a critical site 100 x 109/L

Patients taking antiplatelet medications who require urgent invasive procedures?

  • Platelet transfusion has an undetermined role in this setting
  • Each case should be considered individually
slide-26
SLIDE 26

Invasive Procedures

Procedure Target Platelet Count Non-critical site:

  • Lumbar Puncture
  • OGD & Biopsy
  • Liver Biopsy
  • Transbronchial Biopsy
  • Epidural Anaesthesia
  • Laparotomy

50 x 109/L Critical site:

  • Intracranial
  • Ophthalmic
  • Spine

100 x 109/L

slide-27
SLIDE 27

Therapeutic Transfusion

 Indications for platelets when bleeding:  Active major bleeding e.g. haematemesis

Platelets <50 x 109/L

 Active CNS bleeding

Platelets <100 x 109/L

 Patients requiring massive blood transfusion: follow massive transfusion

protocol

 Active major bleeding on antiplatelet treatment

slide-28
SLIDE 28

Specific scenarios

 Idiopathic Thrombocytopaenic Purpura (ITP)

 Platelet transfusion rarely required, even in severe thrombocytopaenia  Usually only require platelet transfusion in an emergency setting

 TTP, HUS, HIT, DIC

 Complex haematological disorders  All associated with thrombocytopaenia, bleeding AND thrombosis  Require specialist assessment prior to platelet transfusion  Transfusion can be life-saving in major haemorrhage
