目的:探讨延期妊娠并发羊水过少妊娠结局及其相关因素。方法:选择2010年1月～2012年6月在我院住院分娩的孕产妇486例,其中延期妊娠并发羊水过少108例,回顾性分析相关临床资料。结果:①羊水过少产前超声检查总体符合率为91.67%。②羊水过少组引产率、产后出血率、难产率及产褥感染率均比羊水量正常组明显增高,P<0.05有显著性差异。③羊水过少组胎儿窘迫和新生儿窒息发生率均明显高于羊水量正常组,差异有统计学意义(P<0.05)。④两组巨大儿和低出生体质量儿发生率比较,差异无统计学意义(P>0.05)。⑤108例孕产妇中,发现脐带因素21例,羊水混浊度Ⅱ度及以上26例,胎盘Ⅲ级44例,伴有钙化87例,胎盘发育异常15例,胎盘见梗死灶6例,绒毛膜羊膜炎9例。结论:羊水过少可直接影响胎儿宫内生长环境,强化孕产妇系统管理,严密监护,积极处理,适当放宽手术指征对于延期妊娠孕产妇改善母婴并发症具有重要意义。
Objective: To investigate the relationship between prolonged pregnancy associated with oligohydramnios and its related factors. Methods: 486 pregnant women were hospitalized in our hospital from January 2010 to June 2012. 108 cases of oligohydramnios with delayed pregnancy were analyzed retrospectively. Results: ① oligohydramnios prenatal ultrasound combined with the overall compliance rate of 91.67%. ② In oligohydramnios group, the rate of induced abortion, the rate of postpartum hemorrhage, the rate of dysthymia and the rate of puerperal infection were significantly higher than those in the normal amniotic fluid group, P <0.05 had significant difference. ③ oligohydramnios fetal distress and neonatal asphyxia were significantly higher than the incidence of normal group, the difference was statistically significant (P <0.05). There was no significant difference between the two groups in the incidence of macrosomia and low birth weight (P> 0.05). ⑤108 cases of pregnant women, found in 21 cases of umbilical cord factors, amniotic fluid turbidity Ⅱ degree and above 26 cases, placenta grade 44 cases, with calcification in 87 cases, 15 cases of placental dysplasia, placental infarction in 6 cases, chorionic amniotic membrane 9 cases of inflammation. Conclusions: Too little oligohydramnios can directly affect the intrauterine growth environment, strengthen the maternal system management, closely monitor and treat it actively. It is of great significance to relax the indications for pregnant women and maternal to improve the maternal and infant complications.
