产前B超诊断胎儿脐带绕颈的临床应用价值

Clinical value analysis of prenatal B ultrasound in diagnosis of nuchal cord on perinatal infants

目的探讨产前B超诊断胎儿脐带绕颈的临床应用价值。方法选取2013年9月至2015年9月在我院住院分娩的212例产妇的临床资料,并对其进行回顾性分析。按照随机平均的原则将其分为彩色多普勒血流显像组(CDFI组)和B超组。B超组106例产妇采用B超检查对胎儿脐带绕颈情况进行详细诊断,CDFI组106例产妇采用CDFI进行诊断。诊断结束后,对两组产妇诊断符合率、不良妊娠反应发生率及诊断的费用进行比较分析。结果 B超组产妇诊断的符合率达到92.98%,CDFI组产妇诊断的符合率为91.80%。另外,B超组不良妊娠发生率为21.70%,CDFI组不良妊娠发生率为20.75%。经过比较,两组产妇产前诊断的符合率、不良妊娠发生率比较,差异不具有统计学意义(P>0.05)。但CDFI组产妇诊断的平均费用显著高于B超组(P<0.05)。结论 B超检查及CDFI检查对胎儿脐带绕颈的有效率均较高,但行B超检查的费用较低,对产妇及其家庭的经济压力较小,因而值得在临床上应用推广。

Objective To investigate clinical value of B ultrasound in diagnosis of nuchal cord on perinatal infants. Methods The clinical data of 212 cases of puerpera admitted in our hospital from September 2013 to September 2015 was retrospectively analyzed. In accordance with the principle of random average, the puerpera were divided into CDFI group and B ultrasound group. The 106 cases in B ultrasound group used B ultrasound to diagnose nuchal cord on perinatal infants, while 106 cases in CDFI group used CDFI diagnosis. After diagnosis, the diagnosis accordance rate, incidence of adverse pregnancy and diagnosis cost were compared between the two groups. Results The diagnostic accordance rate of B uhrasound group reached 92.98%, and CDFI group was 91.80%. In addition, the adverse pregnancy rate of B ultrasound group was 21.70%, while the CDFI group was 20.75%. After comparison, the diagnosis coincidence rate and incidence rate of adverse pregnancy in the two groups had no significant difference （P〉0.05）, but the average cost of CDFI groups was significantly higher than that of the B ultrasound group （P〈0.05）. Conclusion For nuchal cord on perinatal infants diagnosis, the effective rate of B uhrasound and CDFI check are both high, but B ultrasound has lower costs, it costs less economic pressures of maternal family, which is worthy of application in clinical practice.
