摘　　要：目的应用彩色多普勒超声检测晚孕期胎儿脐动脉（UA）、大脑中动脉（MCA）及肾动脉（RA）阻力参数,评价其在胎儿宫内轻度缺氧中的价值。方法选取孕30~40周的孕妇212例,分为高危妊娠组83例和正常对照组129例。应用彩色多普勒超声检测胎儿UA、MCA和RA收缩期峰值流速与舒张末期流速比值（S/D）、阻力指数（RI）及搏动指数（PI）。结果高危妊娠组UA的S/D、RI、PI较对照组均增高（P〈0.01）;MCA的S/D、RI、PI较对照组均降低（P〈0.01）;联合脐动脉S/D〉2.63、RI〉0.61、PI〉0.99和大脑中动脉S/D〈4.0、RI〈0.77、PI〈1.47作为临界点预测高危妊娠胎儿宫内缺氧的灵敏度、特异度分别为96%和91%。结论联合检测脐动脉与大脑中动脉阻力参数对尽早发现胎儿宫内缺氧具有重要意义。Objective To evaluate the value of color Doppler ultrasonography in detecting resistant parameter of blood flow of fetus in late pregnancy on the prediction fetal hypoxia slightly,including middle cerebral artery（MCA）,umbilical artery（UA）,and renal artery（RA）.Methods A total of 212 late pregnant women with a gestation age of 30-40 weeks were selected,including 83 cases of high-risk pregnancy group and 129 cases of normal control group.The ratio of the systolic peak velocity and diastolic velocity（S/D）,resistance index（RI）and pulsatility index（PI）of MCA,UA and RA were measured by color Doppler ultrasonography.Results The S/D,RI and PI of fetal UA in the high-risk group were significantly higher than those in normal group（P〈0.01）.The S/D,RI and PI of fetal MCA in the high-risk group were significantly lower than those in normal group（P〈0.01）.The sensitivity and specificity of the resistant parameter of UA and MCA in predicting fetal hypoxia was 96% and 91%respectively.Conclusion It is very significant to detect resistant parameter of UA and MCA on the prediction fetal hypoxia slightly.
