羊水过少对围生期结局的影响

Oligohydramnios: its influence on perineonatal outcome

目的探讨晚期妊娠羊水过少对围生期结局的影响.方法 2003年7月至2004年12月郑州市妇幼保健院应用超声测定羊水指数(AFI),对估测羊水量及分娩时羊水总量＜300mL的230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7.58%(101/1332);有妊娠合并症、并发症的高危妊娠羊水过少多发生于孕37～39+6周,占71.43%(75/105).围生儿死亡率为43.5/万.用超声测定羊水指数作为监测羊水量的指标,符合率为95.92%(188/196).剖宫产率为71.74%(165/230).结论诊断羊水过少孕妇,应根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.

Objective To do research on the effects of oligohydramnios in third trimester on the perinatal outcomes. Methods From Jul. 2003 to Dec. 2004, ultrasonography was used in Zhengzhou City Mother and Child Health Care Hospital and other hospitals to determine the volume of amniotic fluid and amniotic fluid in labour. The clinical condition and perineonate mortality rate of 230 cases of women with total amniotic fluid in labour less than 300ml, also be analyzed. Results Occurrence of oligohydramnios in 40 -42^＋6 th gestational week constituted 7. 58% （101/1332） ;occurrence of oligohydramnios with high-risk pregnancy in 37 -39^＋6 th gestational week constituted 71.43% （75/105）. In 98 cases of fetal distress, 69 were with contaminated amniotic fluid of degree Ⅱ and 26 cases of degree Ⅲ, one dead fetus. The perineonate mortality rate was 4. 35‰. To determine oligohydramnios with AFI, the accord rate was 95.92% （188/196） , The rate of cesarean section was 71.74% （ 165/230 ）. Conclusion The gravid women with oligohydramnios during labour diagnosed by 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.
