1

What are the indications for transfusing red cells?

- Severe acute anaemia
- improve QOL in otherwise uncorrectable anaemia
- prepare for or recover from surgery
- Reverse damage by own red cells e.g. sickle cell

2

What are the indications for platelet transfusion?

HAemorrhage
Bone marrow failure
Prophylaxis for surgery
Bleeding Cardiopulm bypass

3

What are the indications for giving FFP?

Replace fluid in Massive HAemorrhage
DIC with bleeding (replaces clotting factors)
Prophylaxis

4

What do you need to do before giving FFP?

Get it out early, stored frozen so takes a while to thaw

Test the PT & aPTT

5

When do we use cryoprecipitate and what do we need to do before using it?

If they have a low fibrinogen

Stored frozen so give time to thaw and test fibrinogen

6

When ordering blood (non-emergency) you send 2 samples to the blood bank, what do they do with them?

Group & screen
Cross Match
Coomb's Test
- Direct = Autoimmune
- Indirect = Cross matching issue

7

What do you do if you need blood immediately?

Ask for Type O RhD -ve red cells
Or AB plasma

If it's urgent but not immediate you can ask for type specific and if it's not urgent at all they will do a full cross match

8

What do you do if a patient has a massive haemorrhage?

Dial 2222 (universal in uk)

It'll get you an immediate supply of 6 units red cell, 4 units ffp & 1 unit platelets

9

What are the major complications of a blod transfusion?

TACO - Transfusion associated circ overload
Fever
TRALI - Tranfusion associated lung injury
Acute Haemolysis
Infections
Anaphylaxis

10

What do we do if someone has a reaction to a transfusion?

Stop it
Check patient identity against component label


Fever - give anti-pyretic & send back to lab for testing

Urticaria - give anti-histamine & monitor for anaphylaxis


Watch out for dyspnoea, shock etc.

11

What is Haemolytic Disease of foetus & Newborn?

Mum with Anti-D Abs passes them on to Rhd +VE baby --> Haemolysis

12

How do we prevent and treat HDFN?

Give mothers Anti-D at 28wks & at delivery, this should prevent baby developing RhD

Antibody titres & doppler US --> Intrauterine transfusion

13

What is NAIT?

Neonatal Alloimmune Thrombocytopenia

Similar to HDFN but for platelets

14

What other transfusion-type interventions can we do for other cells?

Leucapharesis
Bone marrow transplant
Lymphocyte infusions
Other banks e.g. milk, tendons, faecal etc
Gene therapies
