Clinical practice
Red cell transfusion
Two questions need to be answered before transfusion of red cells is undertaken:
Some general indications for red cell transfusion are listed in Table 42.1.

Practicalities of red cell transfusion
All those involved in the prescription and administration of blood should follow local guidelines with respect to patient identification and the checking of the compatibility and viability of the transfused units. Critical information is contained on the blood bag and the attached compatibility label (Fig 42.1). No discrepancies are permissible. Most serious adverse transfusion reactions are due to transfusion of the wrong blood to the patient (Fig 42.2). Errors can be reduced by newer technologies such as bar coding and radiofrequency chips – these generally rely on machine readable data on patient wristbands.
