摘　　要：目的探讨脐动脉S/D比值在双胎妊娠中预测胎儿发育状况的临床意义。方法2007年8月～2009年7月在本院住院分娩的双胎妊娠孕妇225例,应用超声脐动脉血流检测仪,在B超探头引导下分别对2个胎儿进行脐动脉血流检测,选择2个胎儿脐动脉S/D值差>0.4,110例为研究组,2个胎儿脐动脉S/D值差<0.4,115例为对照组,并随访两组新生儿体重及分娩结局。结果①在研究组中胎儿不均衡生长发生率为61.3%,明显高于对照组中的23.5%,2组比较差异具有统计学意义(P<0.05)。②在研究组中当S/D值异常时发生围生儿不良预后明显高于对照组,2组比较差异有统计学意义(P<0.05)。③在研究组中发生S/D异常为67.3%,且母体并发症发生率明显高于对照组,2组比较差异有统计学意义(P<0.01)。结论脐动脉S/D比值在双胎妊娠中对胎儿协调发育和围产儿预后具有较好的预测价值。Objective To discuss the clinical meaning of the S/D ratio of umbilical artery in forecasting fetal growth of Twins. Methods Two hundreds and twenty-five of twins delivering in our hospital from August 2007 to July 2009 were investigated and the S/D ratio of umbilical Artery were detected by a SOD-Ⅵ device under type-B ultrasonic.one hundred ten twins and with the S/D>0.4 between two fetals as study group and one hundred and fifteen twins with S/D<0.4 of them as control group.,and the delivering & perinatal outcome was observed.Results The S/D ratio of discordant growth in stufy group was 61.3% was higher rhan those in control group 23.5%(P<0.05)..The prevalence of poor perinatal outcome and pregnancy complications were significantly higher in study group whose's S/D≥ the 95th percentile than those in normal(P<0.001).Conclusion The S/D ratio of umbilical artery is a good method to forecast discordant growth in twins.
