目的为超声诊断羊水过少寻求更为适宜的诊断标准。方法分别以羊水指数(AFI)≤5 cm和羊水池最大切面≤2 cm×2 cm 为诊断标准超声诊断羊水过少，采用χ2检验分析两组围产结局。结果 AFI≤5 cm组中有45.2％的孕妇羊水池最大切面>2 cm×2 cm。羊水池最大切面≤2 cm×2 cm组的胎心率异常，羊水II度以上粪染率均高于AFI≤5 cm组(P<0.05)，新生儿5 min低Apgar评分(≤7分) 率和剖宫产率两组差异无显著性意义(P>0.05)。结论以羊水池最大切面≤2 cm×2 cm为标准超声诊断羊水过少更为准确。

Objective　To determine a more appropriate diagnostic criteria of ultrasonography for the oligohydramnios.Methods　Oligohydramnios were determined by ultrasonography in the two groups that were amniotic fluid index (AFI)≤5 cm and the largest pocket of amniotic fluid ≤2 cm in two prependicular planes respectively.χ2 test was used to analyse the perinatal outcome between the two groups.Results　Among the patients with AFI ≤5 cm, 45.2% of them had a largest pocket of amniotic fluid >2 cm×2 cm.The incidence of fetal heart rate abnormalities and the thick meconium were increased in the group with the largest pocket amniotic fluid ≤2 cm×2 cm when compared to the group with AFI ≤5 cm (P<0.05). There were no significant difference between the two groups in the incidence of low Apgar score at 5 minutes and in the cesarean section (P>0.05).Conclusions　It is more accurate criteria that oligohydramnios are diagnosed by ultrasonography with the largest pocket of amniotic fluid ≤2 cm×2 cm.
