AimOur primary aim was to assess the impact of intraoperative cell saver usage on patient exposure to allogenic blood transfusion during elective coronary artery bypass. The secondary endpoint was the impact of cell savage on the units of blood and blood products transfused perioperatively.MethodsA prospective observational cohort study with a historical cohort as a control group was performed in a single tertiary care center. One hundred and twenty-four patients undergoing primary on-pump coronary artery bypass grafting were included. Intraoperative cell salvage was performed in 60 patients (study group) but not in the control group (n = 64). Transfusion data, intensive care unit stay, hospital stay, and postoperative complications were evaluated in the cell saver and control groups.ResultsThe number of patients exposed to allogenic red blood cell transfusion was significantly less in the study group (55% vs. 82.8%; p = 0.001) and the units per patient was also less in the study group (1.10 ± 1.7 vs. 2.25 ± 2.289 units; p = 0.002). However, there was no significant difference in terms of units of purified plasma fraction, platelets, or cryoprecipitate transfused. Intensive care unit stay, total hospital stay, number of reexplorations, complications, readmissions, and 28-day mortality were similar in both groups.ConclusionsIntraoperative cell salvage with a cell saver in patients undergoing primary elective coronary artery bypass decreases the proportion of patients exposed to allogenic red cell transfusions and the number of units of red blood cells transfused.© The Author(s) 2015.
