彩超监测胎儿肾动脉血流预测胎儿宫内窘迫临床分析

目的：分析彩超监测胎儿肾动脉血流预测胎儿宫内窘迫临床价值。方法方便选取并回顾性分析在该院定期产检和分娩的90例孕妇的临床资料，依据胎儿是否存在宫内窘迫现象分为研究组(n=48)及对照组(n=42)，使用彩超对孕妇的肾动脉血流相关指标进行检测，并统计新生儿Apgar评分。结果研究组的脐动脉血流速度值、肾动脉血流速度值、搏动指数、阻力指数分别为(3.24±0.51)、(6.47±2.03)、(1.24±0.14)、(0.74±0.11)，均明显高于对照组的(2.13±0.31)、(5.33±1.22)、(0.95±0.09)、0.55±0.07)，差异有统计学意义(P<0.05)；研究组Apgar评分>7分为16例(33.33%)，明显低于对照组的31例(73.81%)，差异有统计学意义(P<0.05)。结论彩超监测胎儿肾动脉血流可准确预测胎儿宫内窘迫的严重程度，提高胎儿成活率。

Clinical Analysis of Fetal Renal Arterial Blood Flow by Color Doppler Ultra-sonography in Predicting Fetal Distress in Uterus

Objective To analyze the clinical value of fetal renal arterial blood flow by color Doppler ultrasonography in predicting fetal distress in uterus. Methods The clinical data of 90 cases of pregnant women with regular prenatal examina-tion and giving birth in our hospital were retrospectively analyzed, and they were divided into the research group (n=48) and control group (n=42) according to whether there was the distress in uterus phenomenon in fetus, the renal arterial blood flow relevant indexes of pregnant women were detected by color Doppler, and the Apgar scores in newborns were counted. Re-sults The umbilical artery blood velocity value, renal artery blood velocity value, pulsatility index and resistance index in the research group were obviously higher than those in the control group, (3.24 ±0.51), (6.47 ±2.03), (1.24 ±0.14), (0.74 ± 0.11) vs(2.13±0.31),(5.33±1.22),(0.95±0.09),(0.55±0.07)], and the differences were obvious(P<0.05), the number of preg-nant women whose Apgar score>7 in the research group was obviously lower than that in the control group (16 cases vs 31 cases), (33.33% vs 73.81%), and the differences were obvious(P<0.05). Conclusion Fetal renal arterial blood flow by color Doppler ultrasonography can accurately predict the severity of fetal distress in uterus and improve the fetal survival rate.
