THE BENEFIT OF THE HEMONETICS CELL SAVER APPARATUS DURING CARDIAC-SURGERY

This retrospective chart review of 155 patients having coronary artery bypass graft surgery (CABG) over a two-month period determined whether the use of a cell saver apparatus (CSA) (1) reduced or increased the requirements for homologous blood; (2) increased the incidence of postsurgical bleeding; (3) was costeffective. Two groups of patients were identified. Group 1 (n = 99) received both CSA processed red blood cells and homologous blood components. Requirement for homologous blood products was reduced in the first 24 hr after surgery (0.5 ± 1.0 vs 1.3 ± 1.8 units; P < 0.05) when compared with Group 2 (n = 56) in whom only homologous blood products were utilized. More patients in Group 1 had no transfusion requirements (45 vs 8; P < 0.05) and there was no increased risk of major haemorrhage. When the capital costs are included, utilization of the CSA was not costeffective. We conclude that utilisation of a CSA was safe, with no increased risk of bleeding, reduced requirements for homologous blood transfusions, but added to the cost of the procedure. © 1990 Canadian Anesthesiologists.
