Objective: To investigate the intraoperative transfusion requirements in off-pump coronary artery bypass grafting (OPCABG) and the cost implication of blood products and cell savers on a background of limited resources.

Methods: Prospective data collection identified 60 patients undergoing OPCABG surgery at the Eric Williams Medical Sciences Complex, Trinidad and Tobago. Data relating to these patients (including preoperative haemoglobin (Hb), graft number, presence of diabetes, ejection fraction, preoperative serum creatinine, intraoperative blood use and blood loss) and costing for cell saver disposables and prepared donor (or allogenic) blood were obtained.

Results: Twenty units of packed red blood cells (pRBCs) were given in theatre to 27% (16 of 60) of patients. Transfusion requirement was significantly lower in patients with fewer grafts, higher preoperative Hb level and non-diabetic patients. Cell saver disposables and one unit of pRBCs were estimated to cost TT$5000 and TT$1700, respectively. Each patient’s transfusion cost TT$2125.00 per
unit.

Conclusion: The study demonstrates the financial implications of routine cell saver use in OPCABG in a setting of limited resources. The cost-effectiveness of routine cell saver use remains to be elucidated, but we recommend the selective use of cell savers in patients who are at a higher risk for transfusion.
