【摘 要】目的：分析探讨产前B超诊断胎儿脐带绕颈的临床应用价值。方法：选取我院2020年1月至12月接收进行产科产检的产妇共200例作为观察对象，对所有产妇均进行产前B超诊断检查，对B超检查结果进行观察统计，将结果与产后临产结果进行比较。结果：在200例产妇中，经B超检查显示共有40例产妇有脐带绕颈的现象，分别为绕颈1周23例，绕颈2周15例，绕颈3周2例，而产后的临产结果显示有42例脐带绕颈现象，分别为绕颈1周24例，绕颈2周16例，绕颈3周2例，B超诊断结果与产后临产结果相差不明显，数据对比差异无统计学意义（P>0.05）。结论：产前B超诊断胎儿脐带绕颈具有重要的临床诊断价值，诊断准确率较高，对于胎儿脐带绕颈现象可以尽早发现，从而为分娩方式选择可靠的参考依据，提高分娩安全性，保证产妇与胎儿的健康与安全，值得推广与应用于产前诊断中。

【Abstract】Objective：To analyzeand explore the clinical application value of prenatal B-ultrasound in the diagnosis of fetal umbilical cord around the neck.Methods：A total of 200 pregnant women accepted by our hospital for obstetric examination in 2020 were selected as observation objects. All pregnant women were subjected to prenatal B-ultrasound diagnostic examination， and the results of B-ultrasound examination were observed and counted， and the results were compared with the results of postpartum labor.Results： Among the 200 cases of pregnant women， B-ultrasound examination showed that there were 40 cases of pregnant women with umbilical cord around the neck， including23 cases with 1 circle around the neck， 15 cases with 2 circles around the neck， 2 cases with 3 circles around the neck.The postpartum labor results showed that there were 42 cases of umbilical cord winding around the neck， including24 cases around the neck 1 circle， 16 cases around the neck 2 circles， and 2 cases around the neck 3 circles.There was no significant difference between the B-ultrasound diagnosis results and the postpartum labor results， and the difference in data comparison was not statistically significant （P>0.05）. Conclusion： Prenatal B-ultrasound diagnosis of fetal umbilical cord around theneck has important clinical diagnostic value， and the diagnostic accuracy is high. The phenomenon of fetal umbilical cord around the neck can be detected as soon as possible， so as to select a reliable reference basis for the mode of delivery， improve delivery safety， and ensure the health and safety of mothers and fetuses，it is worthy of promotion and application in prenatal diagnosis.

脐带绕颈在产科临床中非常常见，约占总出生人数的20%～25%。其原因与脐带长、胎儿小、羊水过多和胎动频繁有关[1]。大部分胎儿绕颈1周～2周，很少超过3周，文献报道最多9周。缠绕过紧和多个循环会影響胎儿血液供应，导致胎儿心率变化、围产期缺氧、窒息甚至死亡。事实上，影响预后的关键因素不是绕颈周数，而是拔颈后脐带的长度[2]。如果相对长度太短，仍然会导致痛苦的结果。由于脐带相对缩短，影响分娩后胎儿产程减少的情况并不少见，如脐疝、子宫内翻、胎盘早剥和脐带破裂，当发生在有单羊膜囊的双胞胎中时更危险[3]。早期……
