目的 探讨延期妊娠并发羊水过少对母婴的影响。方法 采用回顾性分析方法 ,对延期妊娠分娩的产妇羊水正常组 2 31例及羊水过少组 6 6例进行对比分析。结果 羊水过少组中羊水Ⅱ度以上粪染、胎盘成熟度Ⅲ + 级及胎盘钙化、胎儿窘迫、新生儿窒息率、引产率、产后出血率及剖宫产率均显著高于羊水正常组。结论 羊水过少是胎儿宫内慢性缺氧最敏感的特异性指标 ,不论是延期妊娠还是过期妊娠 ,一经确诊应积极引产 ,估计短时间内不能分娩者 ,宜剖宫产结束分娩。
Objective To investigate the effect of oligohydramnios with delayed pregnancy on maternal and infant. Methods A retrospective analysis was performed to compare the data of 2131 cases of normal pregnant women with amniotic fluid during delivery and 66 cases of oligohydramnios. Results In group with oligohydramnios, amniotic fluid grade Ⅱ and above were meconium-stained, placental maturity Ⅲ + grade and placental calcification, fetal distress, neonatal asphyxia, induction rate, postpartum hemorrhage rate and cesarean section rate were significantly higher than normal amniotic fluid group. Conclusions: Oligohydramnios is the most sensitive and specific indicator of fetal chronic hypoxia, whether delayed or outdated pregnancy, once diagnosed should be active induced labor, it is estimated that a short period of time can not give birth, cesarean section should end childbirth.
