目的探讨超声诊断胎儿脐带绕颈的价值及对胎儿宫内窘迫的预测,及其对选择分娩方式的指导意义。方法对320例经超声诊断的晚期妊娠胎儿脐带绕颈病例进行观察分析,了解胎儿宫内窘迫的情况,并与分娩证实的结果进行对比分析研究。结果 320例超声诊断的胎儿脐带绕颈病例中,产后证实者312例,假阳性率为2.5%。结论应用超声尤其是彩色多普勒血流成像(CDFI)检测胎儿脐带绕颈快捷准确,通过对脐动脉血流参数的测定、胎心率的观察等等还可早期诊断胎儿宫内窘迫,对临床分娩方式和时机的选择,降低围生儿并发症有着极大的临床指导意义。
Objective To investigate the value of ultrasound in the diagnosis of fetal umbilical cord around the neck and prognosis of fetal distress, and its guidance on the choice of mode of delivery. Methods 320 cases of umbilical cord around the neck by fetal ultrasound diagnosis of late pregnancy cases were observed and analyzed to understand the situation of fetal distress and confirmed with the results of labor confirmed comparative study. Results Among 320 cases of fetal umbilical cord around the neck, 312 cases were confirmed by postpartum, the false positive rate was 2.5%. Conclusion Ultrasound, especially color Doppler flow imaging (CDFI) detection of fetal cord around the neck fast and accurate, through the measurement of umbilical artery blood flow parameters, fetal heart rate observation, etc. can also be early diagnosis of fetal distress, the The choice of clinical mode of delivery and timing to reduce perinatal complications has great clinical significance.
