目的分析足月妊娠妇女超声检查提示羊水过少且其原因不明的选择阴道试产与直接剖宫产的新生儿窒息情况。方法选择2003年5月至2007年5月应用超声测定羊水指数(AFI)<5cm且其原因不明自愿选择阴道试产的孕妇118例与羊水过少直接选择剖宫产分娩的124例的新生儿窒息情况进行比较分析。结果剖宫产组新生儿窒息发生率明显低于阴道分娩组,两组比较差异有统计学意义(P<0.05)。结论超声诊断羊水过少的足月妊娠的妇女直接剖宫产能明显降低新生儿的窒息率。
OBJECTIVE: To analyze neonatal asphyxia by vaginal trial and direct cesarean section underwent ultrasound examination in term pregnant women, suggesting that oligohydramnios are deficient. Methods From May 2003 to May 2007, 118 cases of pregnant women with vaginal bleeding less than 5 cm were selected and their reasons for vaginal bleeding were unknown. One hundred and eighty-two newborns with 124 children with oligohydramnios were selected directly by cesarean section. Asphyxia comparative analysis. Results The incidence of neonatal asphyxia in cesarean section group was significantly lower than that in vaginal delivery group, the difference was statistically significant (P <0.05). Conclusions Direct cesarean section with ultrasound in term pregnancies with oligohydramnios can significantly reduce neonatal asphyxia.
