Requesting blood component for TransfusionRequesting blood component for Transfusion

It is a medical responsibility to prescribe blood components or blood products.

The decision to transfuse is based on an assessment of the patient’sassessment of the patient’s clinical conditionclinical condition rather than a given level of hemoglobin.

for e.g. blood transfusion of patients with chronic stable anemia is probably unjustifiable if the hemoglobin level is above 7g per 100ml

All cellular blood products must be infused through an approved blood administration set which already incorporates an in-line filter (170u). It is recommended that administration sets be replaced every 12 hours to prevent bacterial growth. Only sodium chloride 0.9% (normal saline) must be used for priming and flushing.

Special white cell reduction filters are no longer required ( unless a special sticker is found on the blood unit ) as all blood products are filtered at the Blood Transfusion Centre soon after collection from the donor using highly effective techniques.
