目的:研究彩色多普勒超声对晚孕期胎儿脐带绕颈的诊断价值、临床意义及预测胎儿发生宫内窘迫的几率分析。方法:用彩色多普勒超声对晚孕期120例发生脐带绕颈的病例进行二维、血流动力学、胎心率等指标的观察分析,并追踪至分娩后,与临床结果证实的胎儿窘迫情况进行对比。结果:980例晚孕期的产妇,218例被超声诊断有脐带绕颈的胎儿,产后有4例没有脐带绕颈,脐带绕颈中36例发生不同程度的胎儿宫内窘迫。结论:彩色多普勒超声诊断胎儿脐带绕颈有较高的诊断准确率。
Objective: To study the diagnostic value, clinical significance and probability of predicting intrauterine fetal distress of fetal umbilical cord around the neck by color Doppler sonography. Methods: The color Doppler ultrasound in 120 cases of umbilical cord around the neck in the second trimester of pregnancy were observed and analyzed two-dimensional, hemodynamics, fetal heart rate and other indicators, and to track after delivery, and clinical results confirmed fetal distress The situation is compared. Results: Among the 980 pregnant women in the second trimester, 218 were diagnosed with umbilical cord around the neck by sonography. There were no umbilical cord around the neck in 4 cases and 36 cases of fetal distress around the neck around the umbilical cord. Conclusion: Color Doppler ultrasound diagnosis of fetal cord around the neck has a higher diagnostic accuracy.
