Key result
Phosphorylcholine-coated cardiopulmonary bypass circuits resulted in a greater platelet drop compared to balanced-coated circuits (effect size 108.4 vs 68.5).
Why the study?
Bleeding is common in cardiopulmonary bypass surgery due to malfunctioning platelets, prompting investigation into whether different biocompatible circuit coatings affect platelet function.
Does a phosphorylcholine-coated CPB circuit compared to a balanced-coated CPB circuit affect platelet drop in patients undergoing cardiac surgery?

Randomized
No
Does a phosphorylcholine-coated CPB circuit compared to a balanced-coated CPB circuit affect platelet drop in patients undergoing cardiac surgery?
Absolute Event Rate: 108.4% vs 68.5%
In patients undergoing cardiac surgery, phosphorylcholine-coated CPB circuits were associated with a greater drop in circulating platelets compared to balanced-coated circuits.
No takes yet. Share an insight, caveat, or question.
May not yet alter CPB circuit selection; leaves open whether PC-coating better preserves platelets than balanced circuits.
Saleem et al. (2023) conducted an RCT in Patients undergoing cardiopulmonary bypass surgery (n=50). Phosphorylcholine-coated cardiopulmonary bypass circuit vs. Balanced-coated cardiopulmonary bypass circuit was evaluated on Platelet drop (pre-operative to post-operative effect size). Phosphorylcholine-coated cardiopulmonary bypass circuits resulted in a greater platelet drop compared to balanced-coated circuits (effect size 108.4 vs 68.5).
