目的:探讨分析彩超监测胎儿肾动脉血流指标在胎儿宫内窘迫中的预测价值。方法:选择2009年1月~2012年1月做彩色多普勒超声波胎儿检查的50例孕妇,按照胎儿是否出现宫内窘迫分为实验组和对照组,其中实验组的29例孕妇胎儿出现宫内窘迫,21例孕妇胎儿无宫内窘迫设为正常对照组,就两组足月孕妇肾动脉血流速度值、脐动脉血流速度值、阻力指数、搏动指数以及新生儿脐血血气分析和新生儿Apgar评分等应用彩色多普勒检测,并对检测结果记录并进行比较分析。结果:实验组的宫内窘迫胎儿肾动脉血流速度值、脐动脉血流速度值、阻力指数、搏动指数均明显高于对照组,差异有统计学意义(P<0.05)。正常对照组的新生儿脐血血气分析以及新生儿Apgar评分均明显优于宫内窘迫胎儿,差异有统计学意义(P<0.05)。结论:彩超监测胎儿肾动脉血流指标在了解胎儿情况以及筛查胎儿宫内窘迫中有较好的临床价值,对胎儿的宫内窘迫具有较好的预测价值,值得临床推广应用。
Objective: To investigate the predictive value of color Doppler ultrasound in detecting fetal renal artery flow index in fetal distress. Methods: Fifty pregnant women who underwent fetal color Doppler ultrasound examination from January 2009 to January 2012 were divided into experimental group and control group according to whether intrauterine fetal distress occurred or not, of which 29 cases Fetal distress in 21 pregnant women without intrauterine distress was set as the normal control group, the two groups of full-term pregnant women renal blood flow velocity value, umbilical artery blood flow velocity value, resistance index, pulsatility index and neonatal cord blood gas analysis and Neonatal Apgar score and other applications of color Doppler detection, and the test results were recorded and compared. Results: Fetal renal artery blood flow velocity, umbilical artery blood flow velocity, resistance index and pulsatility index in experimental group were significantly higher than those in control group (P <0.05). The neonatal umbilical blood gas analysis and neonatal Apgar scores of the normal control group were significantly better than those of the uterine distress fetus, the difference was statistically significant (P <0.05). Conclusion: The color Doppler ultrasonography can detect fetal renal artery blood flow index in better understanding of the fetus and fetal distress. It has good predictive value for fetal intrauterine distress and is worthy of clinical application.
