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 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 ’ explanation letter (memo) or brief Blood bank WILL NOT reprimand you
Returning unused blood/ blood components Call & inform BB Complete ‘ borang pemulangan darah ’ write a memo or Return blood/ components in separate plastic bags with ‘ borang pemulangan darah/ memo ’
