我院自1985年开始实行计划分娩,其孕周由过期妊娠、延期妊娠到近2年的妊娠大于38周,使过期妊娠发生率逐渐下降。本文随机选择计划分娩200例与同期自然分娩100例相比较,结果计划分娩组总产程较自然分娩组平均缩短1小时余,无早产儿、新生儿呼吸窘迫综合征及足月低体重儿发生。孕38～39周3日内引产成功率明显高于过期妊娠者引产成功率(P<0.01),宫颈成熟者3日内引产成功率明显高于宫颈未成熟者(P<0.05)。因此认为:对妊娠大于38周孕妇实行计划分娩可有效地降低过期妊娠的发生率及过期妊娠对母儿的危害,并可达到缩短产程之目的。
Our hospital since 1985, the planned delivery, the gestational age by the expired pregnancy, delayed pregnancy to nearly 2 years of pregnancy greater than 38 weeks, so that the incidence of late pregnancy decreased gradually. This randomized planned delivery of 200 cases compared with 100 cases of natural childbirth during the same period, the results of planned delivery labor group compared with the average delivery time shortened an hour more than normal, no premature children, neonatal respiratory distress syndrome and full-term low birth weight infants. The successful rate of induction of labor in 38 days to 39 weeks of pregnancy was significantly higher than that of expired pregnancy (P <0.01). The success rate of induced labor in 3 days of cervical ripeners was significantly higher than that of cervical immature (P <0.05). So that: the planned delivery of pregnant women more than 38 weeks of pregnancy can effectively reduce the incidence of overdue pregnancy and maternal and child pregnancy overdue pregnancy, and can shorten the birth process.
