本文分析了我院１９９１～１９９４年早产４５２例，其中ＰＲＯＭ１８９例。ＰＲＯＭ发生率为４１．８％，围产儿病死率为７４．６‰，胎儿宫内窘迫率为８．５％，新生儿窒息率为１２．６％．ＰＲＯＭ组产前感染率为５．８％，高于对照组（Ｐ＜０．００５）。６３．６％的感染发生在破膜２天之内。ＰＲＯＭ组产后子宫内膜炎发生率为３．７％，高于对照组（Ｐ＜０．０５）。ＰＲＯＭ的潜伏期在４８小时内者占６７．７％。ＰＲＯＭ组剖宫产率为２５．４％。ＰＲＯＭ的主要危险是早产和产前、产后感染。本文对早产和ＰＲＯＭ的相互关系及处理进行了讨论。
This article analyzes our hospital from 1991 to 1994 452 cases of preterm labor, of which PROM189 cases. The incidence of PROM was 41.8%, perinatal mortality was 74.6%, fetal distress rate was 8.5% and neonatal asphyxia rate was 12.6%. The prenatal infection rate in PROM group was 5.8%, higher than that in control group (P <0.005). 63.6% of the infections occurred within 2 days of rupture of membranes. The incidence of postpartum endometritis in PROM group was 3.7%, which was higher than that in control group (P <0.05). The incubation period of PROM accounted for 67.7% in 48 hours. The rate of cesarean section in PROM group was 25.4%. The main risks of PROM are prematurity and prenatal and postnatal infections. This article discusses the relationship and management of preterm labor and PROM.
