摘要
目的：研究胎儿肾、脑动脉血流参数和羊水指数与围产儿预后的关系，探讨预测胎儿不良结局的方法。方法：应用彩超Ｄｏｐｐｌｅｒ，根据羊水指数（ＡＦＩ）值，将临产妇分为羊水量过少组、减少组和正常组。测定各组胎儿脑动脉（ＭＣＡ），肾动脉（ＲＡ）血流参数（Ｓ／Ｄ、ＰＩ、ＲＩ）及胎儿小时尿量（ＨＦＵＰＲ），Ｍ／ＲＰＩ。结果：羊水量减少组的胎儿ＲＡ的血流参数明显高于正常组（Ｐ＜０．０１）。ＡＦＩ与ＭＣＡＰＩ，ＨＦＵＰＲ，Ｍ／ＲＰＩ间呈正相关关系（ｒ＝０．２０６，０．５６９，０．３７９；Ｐ＜０．０５～０．０１），而与ＲＡＰＩ及围产儿预后呈负相关关系（ｒ＝－０．３９７，－０．７０２；Ｐ＜０．０１）。
Objective:In order to find a convenient and feasible method of predicting and monitoring perinatal outcome, we studied the correlation between the flow parameters of fetal MCA,RA,amniotic fluid index and perinatal outcome.Methods:According to AFI, 96 patients of third trimester gestation with or without oligohydramnios were divided into three groups. That was,groupl 1(AFI<5.0 cm);group 2(AFI 5.1～8.0 cm);group 3(AFI 8.1～18.0 cm). HFUPR,M/R PI and the flow parameters(S/D,PI,RI) of fetal MCA and RA of each group were measured by using colour Doppler ultrasonography.[WT5”HZ〗Results:The flow parameters of fetal RA in group 1 and group 2 were significantly higher than those of group 3,whereas those of MCA and HFUPR were more lower than those of grop The differences were significant(P<0.01). The positive correlations were observed between AFI and MCA PI,HFUPR.Not only were there negative correlations AFI and RA PI,but also poor perinatal outcome. Conclusions:AFI can be used as a convenient and feasible method of predicting and monitoring perinatal outcome.
