羊水过少对围生儿的影响(附268例报告)

目的 探讨妊娠晚期羊水过少对围生儿的影响.方法 2000年6月-2007年6月住院治疗的妊娠晚期羊水过少孕妇268例(羊水过少组),另随机抽取同期住院分娩且羊水量正常的孕妇300例作为对照(对照组),比较分析羊水过少对围生儿及分娩结局的影响.结果 羊水过少组中胎儿窘迫、羊水粪染、新生儿窒息、吸人性肺炎及围生儿死亡率明显高于对照组(P＜0.05),胎儿生长受限(FGR)、妊娠高血压疾病(HDCP)、过期妊娠等妊娠并发症及胎儿畸形的发生率也明显高于对照组(P＜0.05).羊水过少组剖宫产率明显高于对照组,且羊水越少剖宫产率越高、新生儿评分越低(P＜0.05).结论 羊水过少是妊娠晚期的严重并发症,严重威胁围生儿生命,同时合并妊娠并发症时风险更大,选择最佳分娩方式及时终止妊娠可明显改善围生儿预后.

Influence of oligohydranmios on perinatal infants

Objective To explore the effects of oligohydramnios in the late trimester of pregnancy on perinatal infants.Methods Two hundred and sixty-eight pregnant women with oligohydramnios,admitted from June 2000 to June 2007,were involved in present study,and homochronous 300 pregnant women with normal volume of amniotic fluid were enrolled as control group.The clinical data were analyzed to evaluate the influence of oligohydramnios on perinatal infants and on the outcome of delivery.Results The incidences of newborn distress,meconium-contaminated amniotic fluid,apnoea neonatorum,aspiration pneumonia and perinatal infant mortality were obviously higher in the oligohydramnios group than those in control group(P<0.05),and the incidences of pregnancy complications,such as fetal growth restriction(FGR),hypertensive disorder complications of pregnancy(HDCP),prolonged pregnancy and fetal anomaly were also obviously higher in oligohydramnios group than that in control group(P<0.05).The rate of cesarean section was much higher in oligohydramnios group than that in the control group.And the less the amniotic fluid,the higher the rate of cesarean section was,and the worse the newborn Apgar's Scores would be(P<0.05).Conclusions Oligohydramnios is a severe complication in late trimester of pregnancy,which could seriously imperil the health of the newborn.The risk would increase if there is some complicating condition during pregnancy.It is important to choose a proper modus of delivery and to terminate the pregnancy timely in order to improve the prognosis of the neonate.
