延期妊娠并有羊水过少68例分析

Clinical analysis 68 oligohydraminos in post expected date of confinement pregnancies.

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231例及羊水过少组68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、引产率、产后出血率及剖宫产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 analyse the effects of oligohydramnios in post expected date of confinement pregnancies on both mothers and their babies. Methods: We retrospectively reviewed the records of 299 multiparas in post expected date of confinement pregnancies. Women were divided into two groups(oligohydramnios group n=66,nonnal amniotic fluid group n=231).Characteristics of amniotic fluid, placental maturity, fetal distress,asphyxia neonatorum,labor induced,postpartum hemorrhage and cesarean section were compared between these two groups.Results: The rate of amniotic fluid turbidity Ⅱ～Ⅲ degree,plaental maturity Ⅲ+degree,fetal distress,asphyxia neonatorum,labor indeced,postpartum hemorrhage and cesarean section in oligohydramnios group were significantly higher than those in nornal amniotic fluid group(P<0.05) .Conclusion: In post expected date of confinement pregnancies or prolonged pregnancies,oligohydramnios is a most specific and sensitive marder to diagnostic chronic fctal anoxia in uterus. Once it is accurately diagnosed, we must actively terminate the pregnancy. Cesarean section should be the first choice,if the vaginal delivery can't be expected to initiate in a short period.
