过期妊娠对围产儿的影响早已被公认,如果合并羊水过少则对围产儿的影响更为明显。现将我院1983年1月至1984年12月过期妊娠158例中合并羊水过少的27例进行分析。资料与分析一、羊水过少诊断标准及测量方法:人工破膜时无羊水流出或极少流出,并于产时或术中直接目测羊水量,同时参考B超检查结果综合判断。由于羊水量难以准确估计,因此以羊水量明显减少,即少于或等于100ml定为羊水过少[1]。二、发生率:我院1983年1月至1984年12月住院分娩共1641人,过期妊娠158例,其中合并羊水过少27例,占分娩总数1.64％;占过期妊娠总数17.06％。三、过期妊娠合并羊水过少对围产儿的影响见表1。
The impact of overdue pregnancy on perinatal children has long been recognized, if combined with oligohydramnios, the impact on perinatal children is more apparent. Now in our hospital January 1983 to December 1984 expired 158 cases of pregnancy with oligohydramnios 27 cases were analyzed. Data and Analysis First, oligohydramnios diagnostic criteria and measurement methods: artificial rupture of membranes without amniotic fluid outflow or minimal outflow, and during labor or intraoperative direct visualization of amniotic fluid volume, while the reference to B-ultrasound findings combined judgment. As amniotic fluid volume is difficult to accurately estimate, so a significant reduction in amniotic fluid, that is less than or equal to 100ml as oligohydramnios [1]. Second, the incidence: January 1983 to December 1984 in our hospital a total of 1641 hospital deliveries, 158 cases of expired pregnancy, including 27 cases of oligohydramnios, accounting for 1.64% of the total number of deliveries; accounting for 17.06% of the total number of outdated pregnancies. Third, expired pregnancy oligohydramnios on perinatal impact in Table 1.
