中期妊娠引产,是计划生育工作辅助补救措施之一。目前在中期妊娠引产常用的方法有多种,如文献上报导羊膜腔内注入葡萄糖、酒精、尿素、前列腺素、天花粉、穿心连、高渗盐水等,获得较满意的效果。我们自1975年以来,曾先后用过天花粉、过饱和盐水等经腹壁注入羊膜腔内引产,其中天花粉羊膜腔内注入引产共285例,成功率96.85％,平均引产时间为4天8小时36分。但由于天花粉存在过敏反应,我们又出现过轻型过敏反应例子,故现已很少采用。过饱和盐水羊膜腔内注入引产成功率高,惟原法需要用羊水交换,水续见繁。自1976年2月份起,我们开始使用过饱和盐水经腹壁注入羊膜腔内引产(不作羊水交换)至1977年7月底为止,已累积500例,平均引产时间为1天17时18分。从临床实践来看,还是较简便,安全,效果好的。最近我们在翻阅文献过程中发现,此法最早应用于1937年,从40年代至50年代间有报导。据
Midwifery induction of labor is one of the supplementary remedies for family planning work. At present, there are many commonly used methods of induction of labor during the second trimester of pregnancy. For example, glucose, alcohol, urea, prostaglandin, trichosmia, pericardium, and hypertonic saline are injected into the amniotic cavity in the literature to obtain more satisfactory results. We have been used since 1975, has been used trichosanthin, saturated saline and other transabdominal injection of amniotic fluid into the abdomen through the abdomen, which trichostatin injection of induced abortion within the amniotic cavity a total of 285 cases, the success rate of 96.85%, the average induction time of 4 days 8 hours and 36 minutes . However, because of the allergic reaction to TCS, we have seen examples of mild allergic reactions, it is now rarely used. Supramolecular saline into the amniotic cavity into the high success rate of induction of labor, but the original method needs amniotic fluid exchange, water continue to see complex. Since February 1976, we started to inject amniotic fluid via the abdominal wall with saturated saline (without amniotic fluid exchange) until the end of July 1977, and we have accumulated a total of 500 cases with an average induction period of 17:18 on the 1st. From a clinical point of view, it is more convenient, safe and effective. In the recent literature review, we found that this method was first applied in 1937 and reported from the 1940s to the 1950s. according to
