Background:
Off-pump coronary artery bypass surgery should have a significantly lower risk of postoperated bleeding than on-pump surgery. However, the use of a cell saver has been considered necessary, with significant additional cost incurred. Can we consider performing off-pump coronary artery bypass surgery without a cell saver?
Patients And Methods:
A prospective observational study was performed in 68 consecutive patients operated on for 2- or 3-vessel coronary lesions by the off-pump technique.
Results:
The mean number of distal anastomoses was 2.7 ± 0.7. Both internal thoracic arteries were used in 45 patients, and sequential revascularization was performed in 27, with 140 (77.8%) arterial grafts. Cell savers were used in 21 (30.9%) patients. In these 21 patients, the mean volume retransfused after treatment was 315 ± 177 mL. Postoperatively, 11 (16.2%) patients were transfused with packed red blood cells, with a mean volume of 636 ± 234 mL per patient. The 2 factors identified as associated with a higher risk of autotransfusion were female sex and a lower preoperative hemoglobin.
Conclusions:
The use of a cell saver in off-pump surgery is useless in most cases. Careful surgical hemostasis is essential to limit hypovolemia.
