Autotransfusion in hepatic transplantation.

Hepatic transplantation is often accompanied by a large volume of intraoperative blood loss which may place extraordinary transfusion demands on a community blood bank. In an effort to conserve blood bank resources, intraoperative autotransfusion has recently been used in our adult patients undergoing orthotopic hepatic transplantation. A group of seven patients receiving autotransfusion was studied and compared to another group of five patients who did not receive autotransfusion. In spite of receiving more blood during the transplant procedure, the autotransfusion group required a mean of 7.9 units less banked blood. Post-transplant transfusion requirements and bleeding complications were similar in both groups. Hematocrit and total bilirubin were not adversely affected, while transient elevation of BUN and serum creatinine appeared to be unrelated to the salvage process. This procedure was found to be safe and cost-effective, while conserving blood bank resources.
