      【摘要】 目的 研究胎儿肾动脉(RA)与大脑中动脉(MCA)血流阻力指标比值预测妊娠期糖尿病（GDM）胎儿
宫内缺氧的价值。方法 选取2013年8月至2015年2月来我院就诊并被确诊为GDM的孕妇58例作为观察组，选
择同期145例正常妊娠孕妇作为对照组。应用脉冲多普勒技术测量两组胎儿MCA及RA血流阻力指标，如阻力指
数(RI)、搏动指数(PI)和 S/D值，计算RA与MCA阻力指标的比值。结果 观察组胎儿RA的 PI值、RI值、S/D值
均高于对照组，MCA的PI值、RI值、S/D值均低于对照组，差异均有统计学意义(P<0.05)；观察组胎儿阻力指数比
值(RIRA/MCA)、搏动指数比值(PIRA/MCA)及S/D比值(S/DRA/MCA)均高于对照组，差异均有统计学意义(P<0.05)；以上指标分
别大于1.15、1.33、1.41时预测胎儿宫内缺氧的特异性和敏感性分别为92%、90%。结论 RA、MCA血流阻力指标
比值预测胎儿宫内缺氧有重要的临床价值。

【Abstract】 Objective To study resistant parameter ratios of renal artery (RA) and middle cerebral artery
(MCA) in predicting fetal intrauterine hypoxia in gestational diabetes mellitus (GDM). Methods Fifty-eight pregnant
women diagnosed with GDM treated in our hospital from August, 2013 to February, 2015 were selected as the observa-
tion group, and 145 healthy pregnant women were selected as the control group. The MCA and RA blood flow resistant
index (RI), pulsatility index (PI) and systolic/diastolic (S/D) ratio were measured by Putsed Doppler, and the resistant pa-
rameter ratios of RA and MCA were calculated. Results The RI, PI and S/D of fetal RA in the observation group were
significantly higher than those in the control group, and the RI, PI and S/D of fetal MCA in the observation group were
significantly lower than those in the control group (P<0.05). The ratios of RIRA/MCA, PIRA/MCA and S/DRA/MCA in the obser-
vation group were significantly higher than those in the control group (P<0.05). At RIRA/MCA>1.15, PIRA/MCA>1.33 and S/
DRA/MCA>1.41, the specificity and sensitivity for predicting fetal intrauterine hypoxia was 92% and 90%, respectively.
Conclusion Resistant parameter ratios of RA to MCA have significant clinical values in predicting intrauterine hypoxia.
