Thrombocyte levels of patients undergoing open heart surgery were studied to compare effects of a bubble with a membrane oxygenator. Loss of platelets, which is not explained by hemodilution, is smaller in membrane oxygenation and normal level of platelets is readily established postoperatively compared to conventional bubble oxygenation.
