摘 要:目的探讨彩色多普勒超声检测母体子宫动脉的血流动力学参数及血流评分在妊娠期糖尿病孕妇中的诊断价值。方法于2017年9月至2019年8月选择我院产科门诊收治的70例妊娠期糖尿病孕妇(观察组)与70例健康孕妇(对照组)作为研究对象,采用彩色多普勒超声诊断仪对孕妇子宫动脉血流动力学参数进行检测,根据超声血流频谱图评估子宫动脉血流评分。比较两组的子宫动脉血流动力学参数、子宫动脉血流评分、舒张早期切迹发生率、不良妊娠结局;分析子宫动脉血流动力学参数、子宫动脉血流评分、舒张早期切迹与妊娠期糖尿病的相关性;比较观察组不同子宫动脉血流评分孕妇的妊娠结局。结果观察组的子宫动脉搏动指数、阻力指数、S/D值、血流评分、舒张早期切迹发生率均高于对照组,子宫动脉收缩期最大流速、舒张期最小流速均低于对照组(P<0.05)。搏动指数、阻力指数、S/D值、血流评分、舒张早期切迹均与妊娠期糖尿病呈正相关,收缩期最大流速、舒张期最小流速与妊娠期糖尿病均呈负相关(P<0.05)。观察组不同子宫动脉血流评分孕妇的胎儿胎龄、新生儿体重、新生儿Apgar评分有显著差异(P<0.05)。结论彩色多普勒超声检测孕妇子宫动脉血流动力学参数、血流评分可对妊娠期糖尿病予以反映,还可对妊娠期糖尿病孕妇的妊娠结局进行预测。Objective To investigate the diagnostic value of color Doppler ultrasound in detecting maternal uterine artery hemodynamic parameters and blood flow score in pregnant women with gestational diabetes mellitus.Methods From September 2017 to August 2019,70 pregnant women with gestational diabetes mellitus(observation group)and 70 healthy pregnant women(control group)admitted in obstetrics department clinic of our hospital were selected as study objects.The hemodynamic parameters of uterine artery in pregnant women were detected by color Doppler ultrasound diagnostic instrument,the score of uterine artery blood flow was evaluated by ultrasonic blood flow spectrum.The uterine artery hemodynamic parameters,uterine artery blood flow score,incidence of early diastolic notch and adverse pregnancy outcomes were compared between the two groups;the correlation between uterine artery hemodynamic parameters,uterine artery blood flow score,early diastolic notch and gestational diabetes mellitus were analyzed;the pregnancy outcomes of pregnant women with different uterine artery blood flow scores in the observation group were compared.Results The uterine artery pulsation index,resistance index,S/D value,blood flow score and incidence of early diastolic notch in the observation group were higher than those in the control group,while the systolic maximum flow velocity and diastolic minimum flow velocity of the uterine artery were lower than those in the control group(P<0.05).Pulsatility index,resistance index,S/D value,blood flow score and early diastolic notch were positively correlated with gestational diabetes mellitus,while systolic maximum flow velocity and diastolic minimum flow velocity were negatively correlated with gestational diabetes mellitus(P<0.05).There were significant differences in gestational age of fetus,neonatal weight and neonatal Apgar score of pregnant women with different uterine artery blood flow scores in the observation group(P<0.05).Conclusion Color Doppler ultrasound detecting uterine artery hemodynam
