Role of Omega-6 Fatty Acid Metabolism in Cardiac Surgery Postoperative Bleeding Risk

Postoperative bleeding in patients undergoing cardiac surgery is a frequent problem, and this study aimed to test the contribution of metabolic perturbations to platelet dysfunction after cardiac surgery. Patients undergoing elective surgical aortic valve replacement were included in the study. The results suggested that preoperative levels of arachidonic acid may be more relevant than platelet count to anticipate and prevent postoperative blood loss in these patients.
