多普勒超声评估高危妊娠胎儿静脉导管血流动力学及其对宫内缺氧的预测价值
Doppler Ultrasound Assessment of Fetal Venous Catheter Hemodynamics in High-risk Pregnancy and its Predictive Value for Intrauterine Hypoxia
摘要
Abstract
Objective:To explore the value of Doppler ultrasound in evaluating the hemodynamics of fetal venous catheter in high-risk pregnancy and predicting intrauterine hypoxia.Methods:112 pregnant women from January 2020 to January 2022 were selected and divided into high-risk pregnancy group(62 cases)and normal group(50 cases).Doppler ultrasound was used to detect hemodynamic parameters(PS,ED,A)of venous catheter and blood flow indexes of middle cerebral artery and umbilical artery.According to intrauterine hypoxia,the high-risk pregnancy group was further divided into observation group(32 cases)and control group(30 cases).Results:PS[(47.86±6.84)cm/s],ED[(43.71±6.12)cm/s]and A[(25.79±5.48)cm/s]in high-risk pregnancy group were significantly higher than those in normal group(P＜0.05).The S/D value of middle cerebral artery(3.06±0.62)in the observation group was lower than that of the control group(4.61±0.73),and the S/D value of umbilical artery(4.01±0.50)was higher than that of the control group(2.64±0.47)(P＜0.05).ROC curve analysis showed that the AUC values predicted by blood flow indexes of middle cerebral artery and umbilical artery were 0.957 and 0.980,respectively(P＜0.05).Conclusion:Doppler ultrasound can effectively evaluate the hemodynamic changes of fetal venous catheter in high-risk pregnancy,and combined with blood flow monitoring of middle cerebral artery and umbilical artery,it can accurately predict intrauterine hypoxia,which has important guiding significance for high-risk pregnancy.关键词
