廿世纪初德国产科工作者首创腹膜外剖腹产。由于抗生素应用的进展,对本术式有了争议。许多人认为虽对母体安全,但手术时长,难度大,并发症多,且不易掌握,故无必要。本文逐项观察对比1972～1983十年间536例剖腹产中的腹膜外剖腹产346例和经腹膜者190例。腹膜外术式采用耻骨上腹部半月状横切口,暴露和切开腹直肌鞘,用手钝性剥离 Bogros 氏间隙(骨盆腹膜下腔),暴露子宫下段,前表面开一矩形间隙,沿子宫筋膜切开,采用中国乐氏提出的借助宫旁筋膜注入生理盐水进行分离的方法在子宫筋膜平面以牵开器和助手的手进一步暴露子宫下段,做横行切口,胎儿胎盘娩出后,在腹膜外间隙常规放置引流,若 Bogros 氏间
German obstetric workers started the first extraperitoneal caesarean section in the early twentieth century. Due to the progress of the application of antibiotics, this operation has been controversial. Although many believe that maternal safety, but the operation time, difficulty, complications, and not easy to grasp, it is not necessary. This article one by one observed and compared 536 cases of caesarean section during 1972 to 1983, extraperitoneal caesarean section in 346 cases and peritoneal in 190 cases.
