A series of 142 adult patients undergoing open-heart surgery were studied. All known blood-conservativing methods were utilized in an attempt to use as little blood as possible. Hemodilution, autologous transfusion, prevention of wasting of blood, and management of postoperative anemia were the measures employed. An average of 2.66 units of blood were given per patient during the entire hospital stay. Twenty patients were not given any blood at all. The patients were removed from cardiopulmonary bypass without difficulty when the hematocrit reading was in the high teens or low twenties. Later in the postoperative period the patients seemed to progress without difficulty with hematocrit readings of 22 to 25 percent.
对142例接受心脏直视手术的成年患者进行了研究。采用了所有已知的血液保存方法，试图尽量减少血液使用量。所采取的措施包括血液稀释、自体输血、防止血液浪费以及处理术后贫血。每位患者在整个住院期间平均输注2.66单位血液。20例患者根本未输血。当血细胞比容读数处于十七八或二十一二时，患者顺利脱离体外循环。在术后后期，血细胞比容读数为22%至25%时，患者似乎也顺利康复。
