I recently completed my rotation in the IM floor. A patient of ours once needed a blood transfusion and the blood was not flowing as ordered so we decided, in consultation and with the approval of the in-house IM resident, that we needed to place a pressure cuff around the blood bag.
The medical consultant of the patient, upon seeing the patient, ordered that the pressure cuff be removed as it could cause the blood to coagulate. Is this true?
As a student nurse, I have sometimes witnessed blood bags during transfusion with pressure cuffs to ensure adequate flow within the 4 hour period allowed for BT. I have not heard or encountered any problems related to clotting due to the use of a pressure cuff.
