Key result
Cardiopulmonary bypass significantly reduced peak platelet force development compared to baseline (5255 vs 11,600 dynes, P=0.01), with recovery inversely correlating with postoperative blood loss.

Platelet force recovery after CPB may stratify bleeding risk; leaves open utility of force measurements for guiding management.
Observational (n=8)
Does cardiopulmonary bypass reduce platelet force development and correlate with postoperative bleeding in patients undergoing aortocoronary revascularization?
Absolute Event Rate: 5255% vs 11600%
p-value: p=0.01
Cardiopulmonary bypass significantly reduces platelet force development, and this reduction correlates with postoperative blood loss, highlighting a potential mechanism and monitoring tool for CPB-induced coagulopathy.
Greilich et al. (1995) conducted an observational in Aortocoronary revascularization (n=8). Cardiopulmonary bypass vs. Before cardiopulmonary bypass was evaluated on Peak platelet force development (p=0.01). Cardiopulmonary bypass significantly reduced peak platelet force development compared to baseline (5255 vs 11,600 dynes, P=0.01), with recovery inversely correlating with postoperative blood loss.
