彩色超声诊断胎儿脐绕颈的临床运用

Clinical Application of Color Ultrasound to Diagnosis of Fetal Nuchal Entanglement

通过彩色超声产前检查胎儿脐绕颈５０例，与产后对照，４７例阳性，诊断符合率为９４％。其中２１例行剖宫产分娩，１７例出现胎儿宫内窘迫及新生儿窒息，无一例死胎。文中提出脐绕颈是胎儿窘迫和新生儿窒息的常见原因之一。彩色超声检查是确定胎儿脐绕颈的一种简便、可靠的方法，从而为分娩方式提供依据，降低围产儿死亡率。

olour ultrasound was used on 50 prepartum cases for fetal nuchal entanglement.Postpartum results showed 47 positive cases with a 94% diagnostic rate,of which 21 caesarean sections were performed;17 cases were seen with fetal respiratory distress or neonate asphyxia,no fetal death.It is suggested that nuchal entanglement is one of the common causes for fetal respiratory distress and neonate asphyxia,and colour ultrasound diagnosis is a simple and reliable method to detect nuchal entanglement.It also provides the basis for delivery method so as to reduce the perinatal mortality.
