Key result
Autologous blood scavenging using the Sorenson Receptal Device significantly reduced intraoperative homologous blood replacement (1.2 vs 2.7 units) compared to homologous transfusion alone.
Why the study?
Does autologous blood transfusion using the Sorenson Receptal Device reduce the need for homologous blood replacement in patients undergoing aortic surgery?
Cohort (n=50)
Does autologous blood transfusion using the Sorenson Receptal Device reduce the need for homologous blood replacement in patients undergoing aortic surgery?
Absolute Event Rate: 1.2% vs 2.7%
Autologous blood scavenging during aortic surgery reduces intraoperative homologous blood requirements but does not significantly decrease total hospital homologous blood use.
May reduce intraoperative transfusions in aortic surgery; leaves open effects on total hospital use and outcomes.
Twenty-five patients having aortic surgery had blood scavenged using the Sorenson Receptal Device (Group A) and were compared with twenty-five patients having homologous blood transfusion (Group H). Mean intraoperative blood loss was similar in both groups, Group A 3224 (SD 2392) ml, Group H 2999 (SD 1579) ml, but the mean homologous blood replacement was significantly different intraoperatively, Group A 1.2 (SD 1.7) units, Group H 2.7 (SD 1.8) units. Total intra-hospital homologous blood replacement was not significantly different, Group A 4.0 (SD 3.4) units, Group H 5.5 (SD 5.8) units. Mean haemoglobin concentration in the scavenged blood was 8.5 (SD 2.1) g/dl compared to 10.8 (SD 2.4) g/dl in the median aged homologous blood units crossmatched for Group H. Mean red cell half life in the scavenged blood was the same as that for the homologous blood, 24 (SD 5) days, but plasma-free haemoglobin and bacterial contamination was greater in the scavenged blood. There was no difference in the incidence of postoperative renal dysfunction, coagulopathy or mortality between the two groups of patients.

Davies et al. (1987) conducted a cohort in Aortic surgery (n=50). Autologous blood scavenging using the Sorenson Receptal Device vs. Homologous blood transfusion was evaluated on Mean intraoperative homologous blood replacement (units). Autologous blood scavenging using the Sorenson Receptal Device significantly reduced intraoperative homologous blood replacement (1.2 vs 2.7 units) compared to homologous transfusion alone.
