胎儿脐带绕颈的超声诊断时机及临床意义探讨

摘要

Objective To discuss the diagnostic timing and clinical significance of nuchal cord by color Doppler ultrasonography.Method Cases of Nuchal Cord were diagnosed in 5171 pregnant women by ul-trasound detection,and their diagnosis was compared with the result after childbirth.Results In 5171 pregnant women,1016 cases of Nuchal Cord were found after childbirth,the incidence rate was 19.6%. The diagnostic accuracy increased with the increment of gestational weeks.The rate of cesarean section and fetal distress had no significant differences between the normal group and the fetuses with cord around neck group (P>0.05).Conclusions The diagnostic accuracy rate was high in third trimester of pregnan-cy.The diagnosis of Nuchal Cord in third trimester of pregnancy has no obvious influence of the choice of the delivery mode and adverse pregnancy.%目的：探讨彩色多普勒超声诊断脐带绕颈的时机及其临床意义。方法应用彩色多普勒超声对5171例孕妇进行检查并对脐带绕颈者做出诊断，追踪其妊娠结局，与分娩后结果进行对照。结果5171例孕妇分娩后有脐带绕颈者1016例，占分娩总数的19．6％。随着孕周增加超声诊断符合率逐渐增加。脐带绕颈组与未绕颈组比较，其剖宫产率及胎儿窘迫发生率差异比较无统计学意义（P＞0．05）。结论孕晚期脐带绕颈诊断符合率高，晚期诊断脐带绕颈对分娩方式的选择及不良妊娠结局无明显影响。
