目前,国内多用利凡诺羊膜腔内注射进行中期妊娠引产。临床实践证明该法操作简便,成功率高,感染率低。但该法胎膜残留率较高,为其主要缺点。我科过去对胎膜残留者于产后三天常规清宫,但清宫时发现宫腔内刮出的组织极少,刮出物经病理证实为变性坏死的蜕膜。 At present, the domestic use of rivanovol intramuscular injection of mid-term pregnancy induced labor. Clinical practice has proved that the method is simple, high success rate, low infection rate. However, the method of residual membrane rate higher, as its main drawback. My department in the past on the residual fetal membranes in the postpartum routine three days of the Qing, but found in the palace when the curettage out of the organization rarely, scraped by the pathology confirmed degeneration and necrosis of the decidua.
