Key result
A phosphorylcholine-coated cardiopulmonary bypass circuit significantly reduced blood loss during the first 6 postoperative hours compared to an uncoated circuit (171 vs. 285 mL, p=0.024).
Why the study?
Does a phosphorylcholine-coated cardiopulmonary bypass circuit reduce blood loss and preserve platelet function in adults undergoing CABG or mitral valve repair?
RCT (n=40)
randomized
No

Absolute Event Rate: 171% vs 285%
p-value: p=0.024
Phosphorylcholine-coating of the cardiopulmonary bypass circuit significantly reduced early postoperative bleeding, particularly in CABG patients, though it did not significantly affect platelet function markers.

Reduces early blood loss after CABG or mitral repair; extends RCT evidence for phosphorylcholine-coated circuits.
Marguerite et al. (2012) conducted an RCT in Coronary artery bypass graft surgery (CABG) or mitral valve repair using cardiopulmonary bypass (n=40). Phosphorylcholine (PC)-coated cardiopulmonary bypass circuit vs. Uncoated cardiopulmonary bypass circuit was evaluated on Blood loss during the first 6 postoperative hours (p=0.024). A phosphorylcholine-coated cardiopulmonary bypass circuit significantly reduced blood loss during the first 6 postoperative hours compared to an uncoated circuit (171 vs. 285 mL, p=0.024).
