摘　　要：目的检测胎儿大脑中动脉(MCA)、脐动脉(UA)阻力指标比值并分析临床价值。方法应用彩色多普勒技术测定580例妊娠36～41周孕妇的胎儿MCA和UA的收缩期与舒张期血流速度比值(S/D),按计算所得MCA/UA比值分为异常组(<1.3)260例与正常组(≥1.3)320例,追踪母婴结局及分娩方式。结果两组病例的脐带异常、胎儿窘迫和胎儿生长受限的发生率及分娩方式差异有显著性。结论 MCA/UA比值是测定胎儿宫内安危较为灵敏的指标,可指导临床早期诊断,及时采取正确的处理措施,提高产科防治质量。Objective Test the resistance index ratio of fetal middle cerebral artery （MCA） and umbilical artery （ UA）, analysis of the clinical value. Method Using Color Doppler Technique to test 580 cases of pregnancy 36 - 41 weeks pregnant women of fetal MCA and UA systolic and diastolic velocity ratio, according to the calculated MCA（ S/D）/UA（S/D） ratio is divided into abnormal group （〈 1.3 ） and 260 cases of normal group （ ≥ 1.3 ） in 320 cases, tracking pregnancy outcome and mode of delivery. Result In two eases, the incidence of umbilical cord abnormalities, fetal distress and fetal growth restriction and the mode of delivery was statistically significant. Conclusion the MCA （S/D）/UA （S/D） ratio is the determination of fetal distress more sensitive indicators, can guide the clinical early diagnosis, to take timely and correct treatment measures, improve the quality of obstetric control.
