异体输血可引起感染、免疫学反应及移植物抗宿主病等并发症。1989年起作者开始对择期手术且需要输血的儿童实施预先自体血回输(PABT),并对该技术的有效性及安全性进行了探讨。 13名拟择期手术术中可能需要输血的患儿,年龄9个月至10岁(中位年龄21个月),体重7.3～33.6kg(中位体重10.5kg)。其中先天性巨结肠8例、良性肿瘤3例、先天性食管狭窄及肾盂积水各1例。PABT主要程序如下:手术前1～2周预先从患儿动脉、静脉或中央静脉系统采血,采血量以采血后患儿血细胞比容维持
Allogeneic blood transfusion can cause infections, immunological reactions and graft-versus-host disease and other complications. In 1989, the authors began to carry out PABT in children undergoing elective surgery and requiring blood transfusion, and discussed the effectiveness and safety of the technique. Thirteen children scheduled for elective surgery who may need blood transfusions, ranging in age from 9 months to 10 years (median age 21 months), and weighing 7.3 to 33.6 kg (median body weight 10.5 kg). One of 8 cases of Hirschsprung’s disease, 3 cases of benign tumors, congenital esophageal stricture and hydronephrosis in 1 case. PABT main program is as follows: 1 to 2 weeks prior to surgery from children with arterial, venous or central venous blood collection, blood collection to maintain blood hematocrit in children
