*
To adjust intraoperative blood loss and transfusion for age and bodyweight, the total amount in milliliters was divided by the estimated circulating blood volume (CBV) in milliliters. CBV was calculated using a method validated by Schmidt and Thews (39).
†
Severe hemorrhage was defined as intraoperative blood loss > than 50% of CBV (3).
