胎儿宫内窘迫的脐动脉血流动力学检测临床研究

The Study of Hemodynamic Changes in Fetal Distress by Doppler Ultrasonography

目的通过216例临床疑有胎儿宫内窘迫的病例进行彩色多普勒超声检测,探讨其发生率及预测围生儿预后的价值。方法应用彩色多普勒超声血流显像(CDFI)对笔者医院门诊及住院的临床上出现胎儿宫内窘迫症状的孕妇216例进行产前超声检查,观测脐动脉S/D值、RI值、胎儿有无脐绕颈、羊水混浊程度。结果脐动脉S/D值≥3.0,RI≥0.6,发生新生儿窒息的风险高。结论 CDFI检测胎儿脐动脉S/D值、RI值对预测胎儿宫内窘迫、指导分娩方式有重要价值。

Objective To study the occurrence rate of fetal distress and evaluate its value for predicting the prognosis of perinatal babies. Methods The study population comprised 216 pregnancies who had been clinical suspected fetal distress. Umbilical artery peak - systolic/diastolic ratio （S/D）, resistance index （RI） and umbilical cord around neck were examined by color Doppler ultrasonography. Results Pregnancies with umbilical artery S/D≥3.0, R1≥0.6 predicted high risk of fetal hypoxia. Conclusion Umbilical artery S/D, RI detected by color Doppler ultrasound has an important clinical value in predicting fetal distress and estimating delivery mode.
