【摘要】 目的采用B超、胎心电子监护、彩色多普勒脐血流联合监护预测脐带绕颈及胎儿在宫内的缺氧状态,指导医务人员选择适当的分娩方式。方法2004年7~12月间住院分娩的孕妇1233例,于35~38周间行B超检查,对提示脐带绕颈的291例孕妇再进行胎心电子监护和彩色多普勒脐血流联合监护。结果产前B超脐带绕颈预测准确率为76.98%,S/D≥3.0的81例孕妇产后证实均有1~3周绕颈,脐带绕颈的难产率随着绕颈周数增加而上升,新生儿轻度窒息5例,无重度窒息儿。结论脐带绕颈对围产儿存在严重危害,采用联合监护可预测脐带绕颈胎儿的宫内缺氧状态,对分娩方式的选择有很大的帮助。更多还原

【Abstract】 Objective To study umbilical cord entanglement and hypoxia forecast by electronic fetal monitoring, B ultrasound and Doppler umbilical artery flow velocimetry so as to direct selection of ways of delivery. Methods One thousand two hundred and thirty-three cases were examed by B ultrasound during the 35th to 38th week of pregnancy. Neonates with umbilical cord entanglement were analyzed by electronic fetal monitoring and Doppler umbilical artery flow velocimetry. Results The accuracy rate was 76.98% for B ultrasound.There were 1~3 circles of entanglement in 81 neonates with S/D ≥3.0. Five had low Apgar scores. Conclusion Umbilical cord entanglement is harmful to neonates, and combined monitoring can forecast hypoxia of the fetus with umbilical cord entanglement.This helps to select the ways of delivery.更多还原
