The resistance index (RI) of uteroplacental blood flow velocity waveforms (VWF) was investigated by continuous Doppler ultrasound in 286 nonselected pregnant women with singleton pregnancies at 18-21 weeks (n = 129) and at 31-33 weeks (n = 157) of gestation to evaluate the validity of this method as a screening procedure for abnormal pregnancy outcome (intrauterine growth retardation, pregnancy-induced hypertension and fetal asphyxia). The sensitivity of predicting pregnancy outcome was 26.6% at 18-21 weeks and 17.6% at 31-33 weeks of gestation. It was concluded that this method is too insensitive as a screening tool for the prediction of intrauterine growth retardation and pregnancy-induced hypertension in a low-risk nonselected pregnant population.
采用连续多普勒超声研究了286例单胎妊娠的未选择孕妇在妊娠18 - 21周（n = 129）和31 - 33周（n = 157）时子宫胎盘血流速度波形（VWF）的阻力指数（RI），以评估该方法作为异常妊娠结局（宫内生长受限、妊娠高血压和胎儿窒息）筛查程序的有效性。预测妊娠结局的敏感性在妊娠18 - 21周时为26.6%，在妊娠31 - 33周时为17.6%。得出的结论是，在低风险未选择的孕妇群体中，该方法作为预测宫内生长受限和妊娠高血压的筛查工具过于不敏感。
