羊水过少对围生期结局的影响

目的：探讨妊娠晚期羊水过少对围生期结局的影响。方法：2005年1月至2007年12月汕头市妇女儿童医院应用B型超声测定羊水指数（AFI）,对估计羊水量及分娩时直接测定羊水总量〈300m l的371例妊娠妇女临床情况及围生期结局进行分析。结果：羊水过少高发于孕40-42＋6周,占10.07%（154/1529）;有妊娠合并症、并发症的高危妊娠羊水过少大多数发生于孕37-39＋6周,占72.09%（124/172）,围生儿死亡率为53.9/万。应用B型超声测定羊水指数作为监测羊水量的指标,符合率为95.89%（303/316）,剖宫产率为71.43%（265/371）。结论：诊断羊水过少的孕妇,应依据综合检查结果及妊娠是否存在高危因素选择最佳分娩方式及时终止妊娠,可以明显改善围生儿预后。

Oligohydramnion Influence on Perineonatal Outcome

Objective： To research the effects of oligohydramnion in third trimester on the perinatal outcomes. Method： From Jan. 2005 to Dec. 2007, B - type ultrasonography was used in our hospital to determine the volume of amniotic fluid and amniotic fluid in labour. The clinical condition and perineonate mortality rate of 371 cases of women with total amniotic fluid in labour less than 300ml, also be analyzed. Resuit： Occurrence of oligohydramnion in 40 ~ 42 ＋6th gestational week occupied 10.07% （ 154/1529 ） ; occurrence of oligohydramnion with high - risk pregnancy in 37 - 39 ＋6th gestationa[ week occupied 72.09% （ 124/ 172）. The perineonate mortality rate was 5.39‰. To determine oligohydramnion with AFI, the accord rate was 95.89% （303/316 ）, The rate of cesarean section was 71.43% （265/371 ）. Conclusion： The gravid women with oligohydramnion during labour diagnosed by B -type uhrasonography should select the best method of delivery , or pregnancy should be terminated, basing on comprehensive examination and whether there exist high risk factors to improve the perienatal outcomes.
