摘要
本文总结了我院近两年来B型超声诊断延、过期妊娠羊水量215例,探讨羊水量与孕周、羊水过少与胎儿预后、分娩方式之间的关系。结果表明:羊水过少既可发生在过期妊娠,也可发生在延期妊娠;羊水过少组胎儿预后差,剖宫产率达62.2％,显著高于对照组(38.4％)。因此,对延、过期妊娠羊水过少者必须加强监护,尽早处理。在选择分娩方式方面,可适当放宽剖宫产指征,以利降低围产儿的发病率和死亡率。
From July, 1985 to June, 1987, the amniotic fluid volumes in 215 cases of delayed and prolonged pregnancies were examined with ultrasound type B. The relationship between oligohydramnios and fetal prognosis and mode of delivery and the relationship between amniotic fluid volume and weeks of gestation were discussed. The statistical results indicated that oligohydramnios occured not only in prolonged pregnancy, but also in delayed pregnancy. The fetal prognosis of group of delayed and prolonged pregnancies with oligohydramnios was worse than that of normal-group and the cesarean section rate (62.2%) of the former group was higher than that (38.4%) of the latter group. Therefore, The pregnant women with oligo-hydramios should be carefully monitored and early measures should be taken. In order to reduce the perinatal morbidity and mortality, it is necessary to appropriately relax the requirement of indications of cesarean section.
