摘　　要：目的　运用脐血流音频多普勒信号零极点模型评价胎盘功能。方法　对 3 0例正常与 19例异常妊娠妇女进行彩色多普勒超声检查 ,测定脐血流音频多普勒信号和血流阻力指数 (RI) ,并运用零极点模型分析脐血流音频多普勒信号参数分布规律 ,比较两种方法对异常妊娠的检出率。结果　以零极点模型获得的参数 (d、e)对异常妊娠的检出率较RI高 (P <0 .0 5 )。结论　脐血流音频多普勒零极点模型是一种评价胎盘功能的新方法。Objective To evaluate the value of zero pole distributioin of audio Doppler in umbilical artery when monitoring placenta function.Methods Audio Doppler of umbilical artery was analyzed by zero pole distribution of 30 normal pregnant women and 19 abnormal pregnant women,and compared with the resistance index(RI).Results The method of zero pole distribution was better than RI in assessment of abnormal pregnancy(P< 0.05 ).Conclusion The zero pole distribution of audio Doppler in umbilical artery is a new and sensitive method to evaluate placenta function.
