Abstract: | Objectives. Off-pump coronary surgery reduces transfusions, however, many patients still receive blood. This trial aims to clarify the effect of using a cell saver intraoperatively. Design. In 60 patients shed blood was collected in the cell saver reservoir intraoperatively; randomization and processing or discharge were performed immediately after surgery. Primary outcome measures: proportion of patients receiving allogeneic blood, and average number of units per patient. Secondary outcome measures: blood loss, hemoglobin levels, complications, and costs. Results. Cell saver group versus control group; received transfusions: 17/30 vs. 14/29 (p?=?0.28), allogeneic units: median 1 (interquartile range 0 – 2) vs. 2 (IQR 0 – 7) (p?=?0.06), intraoperative net blood loss: median 300 ml (IQR 193 – 403) vs. 610 ml (IQR 450 – 928) (p?<?0.001). Control group patients had more complications leading to transfusion. Hemoglobin levels and costs were comparable between groups. Conclusions. Use of cell saver reduced intraoperative net blood loss and seemed to reduce transfusions by 1 unit per patient, however, this was probably attributable to more complications leading to transfusion in the control group. In the future larger trials are necessary. |
