Key result
Use of a cell saver during elective abdominal aortic aneurysm surgery significantly reduced intraoperative bank blood transfusion compared to conventional drainage (0.6 vs 3.3 units, P<0.0001).

The use of a cell saver during elective abdominal aortic aneurysm surgery significantly reduces the need for perioperative bank blood transfusion.
May reduce bank blood transfusion in elective AAA repair; hypothesis-generating and requires RCT confirmation before practice change.
One hundred and two patients undergoing elective abdominal aortic aneurysm repair and admitted to ICU at RPAH in 1989/90 were studied. In forty patients a cell saver was used during the operative procedure (Group CS) while in the remaining sixty-two patients intraoperative blood loss was drained and discarded conventionally (Group NCS). Preoperative ASA grade and postoperative APACHE score were similar in these two groups. The amount of bank blood transfused intraoperatively was less in Group CS than in Group NCS (0.6 +/- 0.2 vs 3.3 +/- 0.3 units) (mean +/- SEM) (P less than 0.0001). The total amount of bank blood transfused during hospital admission was also less in Group CS (1.5 +/- 0.4 vs 4.8 +/- 0.4 units, P less than 0.0001). Of Group CS, 22 patients (55%) received no bank blood compared to two patients (3%) in Group NCS. There was no difference between the groups with respect to postoperative haemoglobin and creatinine levels. ICU stay was similar in both groups. We conclude that use of the cell saver reduces perioperative bank blood transfusion in elective abdominal aortic surgery.

Brown et al. (1991) conducted an observational in Elective abdominal aortic aneurysm (n=102). Cell saver vs. Conventional drainage and discarding of intraoperative blood loss was evaluated on Amount of bank blood transfused intraoperatively (units) (p=<0.0001). Use of a cell saver during elective abdominal aortic aneurysm surgery significantly reduced intraoperative bank blood transfusion compared to conventional drainage (0.6 vs 3.3 units, P<0.0001).
