心内直视手术中输自体血临床研究

１９８９～１９９３年的４年中，共进行心内直视手术时输自体血１７５５例（其中成人１５５５例，儿童２００例），共放出自体血１０５万ｍｌ，平均每例放血６００ｍｌ。患者年龄最小生后６２天，最大７４岁，体重最轻４．５ｋｇ，最重９８ｋｓ。本文推道了临床情况放血方法及一系列临床科研工作。此项工作培养了干部，节约了库血，减轻了患者经济负担和减少手术后肝炎发生的危险，应广为宣传应用。

STUDY OF AUTOLOGOUS BLOOD TRANSFUSION IN OPEN HEART SURGERY

Reduction in the volume of homologous blood trnsfused during and after open heart surgery could save bank blood and reduce the incidence of serum hepatitis, transfusion reaetions, and the sequelae due to progressive deterioration of blood stored in acidcitrate-dextrose solution. We used autolgous transfusion technique in 1775 patients. A total of 105l168 ml of autologous blood was withdrawn prior to bypass.The fresh autologous blood was transfused after bypass. We have also studied the hemodynamics, blood oxygen saturation, microcirculation and blood rheology during moderate hemodilution. It is concluded that autologous blood donations are safe for patients with cardiac disease and effective in significantly reducing bank blood need in patients undergoing open heart surgery.
