摘　　要：目的：评价彩色多普勒超声检查在围产儿监护方面的价值。方法：对２２例胎儿宫内缺氧（宫内窘迫组）和６例围产儿死亡（围产儿死亡组）的胎儿胎盘血管超声结果进行分析，同时与同期５５５例妊娠３６～４０周正常妊娠胎儿（正常妊娠组）比较。使用仪器为ＵＭ９ＨＤＩ彩色多普勒超声诊断仪。结果：与正常妊娠组比较，胎儿宫内窘迫组胎儿肾动脉、脐动脉和胎盘床动脉阻力均显著升高，大脑中动脉阻力无变化；围产儿死亡组中，除胎儿外周血管阻力升高外，其大脑中动脉阻力明显降低，以及脐动脉和肾动脉舒张期血流缺如或返流。结论：胎儿宫内缺氧使胎儿血液动力学发生明显的变化，血液动力学变化，对预测胎儿宫内缺氧具有一定的价值。Objective:ToevaluatethevalueofcolorDopplerultrasoundexaminationinperinatalmonitoring.Method:Dopplerultrasoundresultsof22caseswithfetalstressand6caseswithperina-talmortalitywereretrospectivelyanalyzed,andcomparedthatof555normalpregnancieswithsamegestationalage(36to40weeks)usingUltramark9HDIcolorDopplerultrasound.Results:There-sistanceoffetalumbilicalartery(FUA),fetalrenalartery(FRA)andplacentalbedartery(PBA)infetalstressgroupweresignificantlyhigherthanthatinnormalpregnantgroup;therewerenochangesofresistanceinmiddlecerebralartery(MCA).Inperinatalmortalitygroup,theresistanceofFUA,FRAandPBAwerethehighest,theresistanceofMCAwasthelowest,andend-diastolicflowinFUAandFRAwereabsentorreverse.Conclusion:Theresultsshowedthatfetalandplacen-talflowdynamicsstudyexami-nedbycolorDopplerultrasoundisanefectivemethodintheassess-mentoffetalwel-being.
