摘要/Abstract

摘要： 文章分析了超声脐动脉收缩期末最大血流速度（S）/舒张期末最大血流速度（D）值联合胎心率监测对新生儿窒息的临床诊断价值。选取发生新生儿窒息的98例产妇作为窒息组，新生儿正常的98例产妇作为未窒息组，比较两组胎心率监测情况和脐动脉血流动力学指标阻力指数（RI）、搏动指数（PI）、S/D值。分析胎心率监测和S/D值与阿氏评分的相关性，比较胎心率监测和S/D值单一及联合监测对新生儿窒息的诊断效能。结果显示，窒息组胎心率监测异常率（87.76%）高于未窒息组（18.37%）（P<0.05）。窒息组脐动脉RI、PI、S/D值均高于未窒息组（P<0.05）。胎心率监测异常、S/D值与阿氏评分呈负相关（P<0.05）。胎心率监测和S/D值联合检测的灵敏度及准确率均显著高于单一检测（P<0.05）。超声脐动脉S/D值联合胎心率监测对新生儿窒息的诊断效能高于单一检测。

Abstract: The aim of this study was to analyze the clinical diagnostic value of maximum blood flow velocity at the end of systole (S)/peak blood flow velocity at end of diastole (D) combined with fetal heart rate monitoring in the clinical diagnosis of neonatal asphyxia. Ninety-eight parturients with neonatal asphyxia were regarded as the asphyxia group, and normal newborns were regarded as the non-asphyxia group (n=98). The fetal heart rate monitoring and the umbilical artery hemodynamic index resistance index (RI), pulsatility index (PI) and S/D values were compared between the two groups. The correlation between fetal heart rate monitoring, S/D value and Apgar score was analyzed. The diagnostic efficacy of fetal heart rate monitoring and S/D value single or combined monitoring for neonatal asphyxia was compared. The abnormal rate of fetal heart rate monitoring in the asphyxia group (87.76%) was higher than that in the non-asphyxia group (18.37%) (P<0.05). The RI, PI and S/D values of the umbilical artery in the asphyxia group were higher than those in the non-asphyxia group (P<0.05). Abnormal fetal heart rate monitoring and S/D value were negatively correlated with Apgar score (P<0.05). The sensitivity and accuracy of combined detection of fetal heart rate monitoring and S/D value were significantly higher than that of single detection (P<0.05). Ultrasound umbilical artery S/D value combined with fetal heart rate monitoring is more effective than single detection in the diagnosis of neonatal asphyxia.
