Problem: underbite
Scheduled for orthognathic surgery
Hb is 11.7 g/dL
Packed red cells are requested
What would you request?
Group, Screen and Hold (GSH) Group:
ABO, Rh grouping
Screen:
antibody screen and identification
Hold:
hold the sample for 48h
How to make a request for GSH Inform patient the possibility of a
transfusion Fill in request form Confirm patient’s identity Take blood sample Label sample at bedside

What would you request?
Group cross-match (GXM)
Group: ABO, Rh grouping
Screen: antibody screen and identification
Cross-match: Immediate spin/ RT LISS 370C AHG
How to make a request for GXM
Making a request for GXM
Inform patient the likelihood of a transfusion Fill in request form Confirm patient’s identity Take blood sample Label sample at bedside
NEVER use pre-printed labels NEVER pre-label tubes
Send sample and request form to BB Collect blood with blood collection slip and blood
box
Blood collection slip
GXM vs. GSH
GSH Blood is not
prepared for patient ONLY the sample is
processed BUT can easily
convert to GXM if required
GXM Blood is prepared for
patient Sample is cross-
matched with donor red cells
BUT this increases workload
Case 3
En SY, 56 year-old man
Presented to A&E with torrential per-rectal bleeding
O/E: Pale+++ PR: 120 BP: 106/60
Packed cells are requested
What would you request?

Send sample + request form a.s.a.p
Discuss with blood bank MO on call
Doctor or staff to standby at BB with an ice box
Verify blood upon release
Form: Complete Information COMPLETE INFORMATION
Case 4
21 year-old lady

Collection slip issued once plasma is ready
Form: Complete Information COMPLETE INFORMATION
Case 6
26 year-old lady
Elective LSCS for transverse lie
Group B, D negative
GXM 2 units PRBC
Requested for PRBC to be in OT
Case 7
45 year-old lady
Long-term anticoagulation for recurrent DVT
Admitted for elective knee arthroscopy
Warfarin stopped 5 days
INR 1.6 on day before surgery
2 units FFP requested
Case 6 – cont’d
LSCS uneventful
PRBC returned
Was GXM necessary?
Why bring PRBCs to OT when it takes only 20 minutes to convert GSH to GXM?
Case 7 – cont’d
FFP brought to OT
INR 1.3 on day of surgery
Arthroscopy went well
FFP transfused anyway after procedure
Reason: need to write explanation letter to BB
Returning unused blood
Best practice is NOT to remove blood/ components from BB until needed
Packed red cells, whole blood are stored in blood refrigerators at 4±2°C
Domestic refrigerators are not meant for blood
Plasma products (FFP, CryoP) are kept frozen and thawed ONLY upon request
Once thawed, they cannot be frozen again
Returning unused blood
However, DO NOT TRANSFUSE if deemed UNNECESSARY
Best to return than to transfuse inappropriately
If returned: Place PRBC, WB and FFP in blood box with ice Return platelets in blood box without ice Fill in ‘borang pemulangan darah’ or brief
explanation letter (memo)
Blood bank WILL NOT reprimand you
Returning unused blood/ blood components
Call & inform BB
Complete ‘ borang pemulangan darah’ or write a memo
Return blood/ components in separate plastic bags with ‘borang pemulangan darah/ memo’
Memo
Name of patient and AM no.
Type of blood/ component
Blood bag no.
Reason/s for returning the blood/ component
Return of Used blood BagProper return of blood components
Improper return of used blood
The next time you decide to transfuse
Stop, think and ask yourself …
Is it really necessary?
Be aware of the risks of transfusion and the morbidity/ mortality associated with it! Febrile/ non-febrile transfusion
reactions
Wrong blood
Bacteremia
Transfusion-related acute lung injury (TRALI)
Transfusion-transmitted infections (TTI)
