We get massive transfusions so rarely that any type of review wouldn't be feasible. However, our protocol states that, after every 10th units of packed cells transfused, the patient is to be drawn for coag profile (PT, APTT, FIB, platelet count), K+, and ionized CA. A full summary of the incident, including chart review, is to be done by the blood bank supervisor, reviewed and signed by the pathologist, and reviewed at the next transfusion committee meeting.
