目的总结脐带绕颈产妇的分娩情况,探讨脐带绕颈对剖宫产率的影响。方法在住院分娩产妇中随机抽取产后证实有脐带绕颈者310例作为观察组,无脐带绕颈者310例作为对照组,观察2组胎心、羊水、产程、分娩方式、新生儿窒息等情况。观察比较产前B超诊断与产后有无脐带绕颈是否相符及脐带绕颈周数与剖宫产的关系。结果脐带绕颈1周组和≥2周组胎心异常率(10.00%vs10.65%)、羊水污染率(13.87%vs12.90%)、剖宫产率(32.58%vs34.52%)、新生儿窒息率(3.87%vs3.23%)比较,差异均无统计学意义(P均>0.05);产程异常率(13.87%vs21.61%)差异有统计学意义(P<0.05)。脐带绕颈1周组和≥2周组之产前B超诊断与产后有无脐带绕颈符合率分别为81.29%和91.69%;剖宫产率2组相当(30.89%vs39.06%,P>0.05)。结论单纯脐带绕颈和脐绕颈的周数并未增加剖宫产率;B超诊断脐绕颈不能作为剖宫产的绝对指征。
Objective To summarize the delivery of umbilical cord around the neck and discuss the effect of umbilical cord around the neck on the rate of cesarean section. Methods A total of 310 cases of umbilical cord around the neck were randomly selected from postpartum mothers as the observation group and 310 cases without the umbilical cord around the neck as the control group. The fetal heart rate, amniotic fluid, labor course, mode of delivery, neonatal asphyxia and so on were observed . Observe and compare the prenatal B ultrasound diagnosis and whether the umbilical cord around the neck after birth and umbilical cord around the number of cervical cesarean section relationship. Results The fetal heart rate (10.00% vs10.65%), amniotic fluid contamination rate (13.87% vs12.90%), cesarean section rate (32.58% vs34.52%), Neonatal asphyxia rate (3.87% vs3.23%) showed no statistical difference (all P> 0.05). The rate of labor abnormality (13.87% vs21.61%) had statistical significance (P <0.05). The coincidence rates of umbilical cord around the umbilical cord around the cervical cord around the neck in 1 week group and in the group of ≥2 weeks were 81.29% and 91.69%, respectively; the rate of cesarean section in the 2 groups was the same (30.89% vs 39.06%, P > 0.05). Conclusions The number of umbilical cords around the neck and umbilical cord around the simple cord did not increase the rate of cesarean section. The diagnosis of umbilical cord neck by ultrasound can not be used as an absolute indication of cesarean section.
