摘　　要：目的探讨超声多普勒血流参数在胎儿缺氧诊断中的应用价值。方法选取2021年1月-2023年6月金溪县人民医院收治的60例孕妇,其中包括30例胎儿缺氧孕妇(研究组)及30例正常孕妇(参照组),两组孕产妇入院后均实施超声多普勒检查,比较两组胎儿脐动脉、大脑中动脉的搏动指数(PI)、阻力指数(RI)以及收缩期峰值血流速度与舒张末期血流速度比值(S/D),并分析不同孕周、不同缺氧程度的大脑中动脉PI、RI、S/D。结果研究组脐动脉PI、RI、S/D值高于参照组,差异有统计学意义(P<0.05);研究组大脑中动脉PI、RI、S/D值低于参照组,差异有统计学意义(P<0.05);37~40周、>40周大脑中动脉PI、RI、S/D值低于32~36周,差异有统计学意义(P<0.05);处于重度缺氧状态的胎儿大脑中动脉PI、RI、S/D值低于处于轻度缺氧状态的胎儿,差异有统计学意义(P<0.05)。结论超声多普勒血流参数在胎儿缺氧诊断中的应用价值较高,可为临床治疗提供有效的参考依据。Objective To explore the application value of ultrasound Doppler blood flow parameters in the diagnosis of fetal hypoxia.Methods A total of 60 pregnant women admitted to Jinxi County People′s Hospital from January 2021 to June 2023 were selected,including 30 pregnant women with fetal hypoxia(study group)and 30 normal pregnant women(reference group).Both groups of pregnant women were examined by ultrasound Doppler after admission.The pulsatility index(PI),resistance index(RI)and the ratio of peak systolic blood flow velocity to end diastolic blood flow velocity(S/D)of fetal umbilical artery and middle cerebral artery were compared between the two groups,and the PI,RI and S/D of middle cerebral artery with different gestational weeks and different degrees of hypoxia were analyzed.Results The PI,RI and S/D values of umbilical artery in the study group were higher than those in the reference group,and the differences were statistically significant(P<0.05).The PI,RI and S/D values of the middle cerebral artery in the study group were lower than those in the reference group,and the differences were statistically significant(P<0.05).The PI,RI and S/D values of middle cerebral artery in 37-40 weeks and>40 weeks were lower than those in 32-36 weeks,and the differences were statistically significant(P<0.05).The PI,RI and S/D values of fetal middle cerebral artery in severe hypoxia were lower than those in mild hypoxia,and the differences were statistically significant(P<0.05).Conclusion The application value of ultrasonic Doppler blood flow parameters in the diagnosis of fetal hypoxia is high,which can provide an effective reference for clinical treatment.
