随着剖宫产手术率的不断上升,剖宫产所致并发症亦相应增加。子宫下段横切口感染所致晚期产后出血,是严重并发症之一。我院自1981年1月1日～1984年12月分娩总数13041例,剖宫产1298例占9.95％,子宫下段横切口剖宫产1060例,占剖宫产手术81.66％,发生晚期产后出血2例,占下段横切剖宫产0.19％。现把这2例报告如下。例1 24岁,住院号387789。孕1产1,因剖宫产术后30天,阴道大流血、不省人事,于1981年10月6日急诊入院。患者于1981年9月6日因滞产30小时,破水2小时,宫口开大4cm,胎儿宫内窘迫,于硬膜外麻醉下行子宫下段横切口剖宫产。手术按常规进行,娩出胎儿较困难。切口以Ⅰ号铬制肠线连续缝合肌层两层,并以00号铬制肠线连续缝合膀胱反折腹膜。切口7天拆线,Ⅰ期愈合。术后10天出院。产后30天早 With the rising rate of cesarean section operation, the complications caused by cesarean section also increased accordingly.
