目的探讨B超产前诊断胎儿脐带绕颈的诊断价值及临床意义。方法对近3年在我院产检并住院分娩的孕产妇于产前1-2周内常规B超检查有无脐带绕颈进行回顾分析。结果脐带绕颈组阳性符合率94.2%。对照组阴性符合率92.8%。脐带绕颈组手术率52.0%,对照组34.1%,有显著性差异(P<0.01)。两组胎儿宫内窘迫率,脐带绕颈组明显高于对照组,但新生儿窒息率前者较后者明显下降。两组有显著差异(P<0.01)。结论B超产前诊断脐带绕颈安全,可靠,准确性高。重视脐带绕颈的早期诊断,加强产时胎儿监护,可降低因脐带绕颈引起造成的不良结局。
Objective To investigate the diagnostic value and clinical significance of fetal prenatal diagnosis of umbilical cord around the neck. Methods In the past three years in our hospital for quarantine and hospital delivery of pregnant women in the prenatal 1-2 weeks routine B-ultrasound with or without umbilical cord around the neck for retrospective analysis. Results The positive coincidence rate of umbilical cord around the neck group was 94.2%. The negative rate of the control group was 92.8%. The operation rate of umbilical cord around the neck group was 52.0% and that of the control group was 34.1%, with significant difference (P <0.01). Two groups of fetal distress rate, umbilical cord around the neck group was significantly higher than the control group, but the former neonatal asphyxia than the latter decreased significantly. There was significant difference between the two groups (P <0.01). Conclusion B-prenatal diagnosis of umbilical cord around the neck safe, reliable and accurate. Emphasis on the early diagnosis of umbilical cord around the neck, strengthen fetal care during labor, can reduce the umbilical cord caused by the neck caused by adverse outcomes.
