超声诊断胎儿脐带绕颈周数的临床价值

Clinical Significance of Ultrasonic Diagnosis on Fetal Umbilical Cord Around Neck

目的讨论超声诊断胎儿脐带绕颈周数的临床意义,为临床选择正确的分娩方式提供科学的诊断依据。方法对足月妊娠者产前1周内进行常规超声检查,并将其分为无脐带绕颈组、脐带绕颈1周组、脐带绕颈≥2周组。对比分析各组间胎儿宫内窘迫、分娩方式的差异。结果超声诊断脐带绕颈397例,其中脐带绕颈1周259例,脐带≥2周138例。脐带绕颈一周组与无脐带绕颈组在胎儿宫内窘迫,分娩方式无显著性差异;而脐带绕颈≥2周组与脐带绕颈一周组在宫内窘迫,分娩方式有显著性差异(P<0.01)。结论超声诊断胎儿脐带绕颈周数有很高的特异性及准确性,脐带绕颈周数的确定对临床分娩方式的选择及降低围产儿并发症有重要的意义。

Objective To discuss the clinical significance of circle number of cord aound neck in order to choose the correct scientific basis for the clinical delivery means. Methods Give a routine ultrasound examine to flail-term pregnancy woman a week before delivery,and divided them into three groups：no cord aound neck group, one circle cord aound neck group and ≥ 2 circle cord aound neck group. Contrastively analyze the differences of distress and delivery means among three groups. Results 397 cases were diagnosed as cord aound the neck,of which 259 cases were one circle cord aound the neck, 138 cases were ≥2 circle. There was no obvious difference between no cord aound the neck group and one circle group. There was obvious difference between one circle group and ≥ 2 circle group. Conclusion Ultrasound examination has high specificity and accuracy to circle number of fetal cord aound the neck. Circle number of fetal cord aound the neck is important for choice of delivery means and reduce perinatal complications.
