Effects of a Leukocyte Depleting Arterial Line Filter on Perioperative Morbidity in Patients Undergoing Cardiac Surgery: A Controlled Randomized Trial

Leukocyte filtration in patients undergoing cardiac surgery with extracorporeal perfusion showed no measurable effects on postoperative morbidity. However, although not statistically significant, a decrease was observed in the rates of perioperative infection, fever, and hyperdynamic states.
