During a recent seven mouth period of time, patients with intrathoracic and intraabdominal injury had recovery of shed blood utilizing a Haemonetics Cell Saver. Blood is suctioned from the surgical field or with tube thoracostomy. Autotransfusion is sufficient for four patients; five others patients need blood transfusion, for intraoperative or postoperative hemorrhage. However, the decrease of transfusion requirement is evident, and autotransfusion is equivalent to 8.6 concentrated red cells units for each patient, as 2.6 homologous bank blood concentrated red cell units. The difficulties are nurse training, and cost (to be compared with homologous bank blood cost); but autotransfusion with Haemonetics Cell Saver 4 is sizeable part of transfusion therapy of acute trauma.
