经会阴超声测量中孕期宫颈管长度在预测早产中的临床应用

Clinical Application of Transperineal Ultrasonography in Predicting the Length of Cervical Canal during Pregnancy in Preterm Delivery

目的探究经会阴超声测量中孕期宫颈管长度在预测早产中的临床应用价值。方法选择本院2018年1月—2020年6月收治的120例孕妇患者作为研究对象,回顾性分析患者的临床资料,根据其是否发生早产分为非早产组(74例)和早产组(46例),患者均行经会阴超声测量,对比非早产组与早产组患者宫颈内口宽度和宫颈管长度,并比较不同宫颈内口宽度和不同宫颈管长度患者早产发生率。结果早产组患者宫颈内口宽度(13.9±2.6)mm显著宽于非早产组(4.3±0.8)mm,早产组患者宫颈管长度(20.7±4.3)mm显著短于非早产组(34.5±6.2)mm,宫颈内口宽度≥5 mm组患者早产发生率(53.3%)显著高于<5 mm组(29.3%);宫颈管长度<10 mm组患者早产发生率(68.8%)显著高于10~30 mm组(39.3%),宫颈管长度10~30 mm组患者早产发生率(39.3%)显著高于>30 mm组(21.7%),各组比较差异有统计学意义(P<0.05)。结论经会阴超声测量中孕期宫颈管长度在预测早产中具有良好的应用价值,宫颈管长度越短,宫颈内口越宽,提示患者发生早产的几率越高。

Objective To explore the clinical value of transperineal ultrasonography in predicting the length of cervical canal in preterm delivery.Methods 120 pregnant women admitted to the hospital from January 2018 to June 2020 were selected as the study subjects.The clinical data of the patients were analyzed retrospectively.According to whether preterm delivery occurred,74 cases were divided into non-preterm delivery group(74 cases)and preterm delivery group(46 cases).All patients were measured by perineum ultrasound to compare the width and length of cervical canal between non-preterm delivery group and premature delivery group,and to compare the incidence of preterm delivery in patients with different cervical orifice width and different cervical canal length.Results Cervical internal orifice in preterm labor group the width of(13.9±2.6)mm was significantly wider than that of the non-preterm delivery group(4.3±0.8)mm.The length of the cervical canal was(20.7±4.3)mm shorter than that of the non-preterm delivery group(34.5±6.2)mm.The incidence of premature delivery in patients with cervical intraoral width≥5 mm(53.3%)was significantly higher than that in patients with<5 mm(29.3%).The incidence of premature delivery in patients with cervical canal length<10 mm(68.8%)was significantly higher than that in 10~30 mm(39.3%).The incidence of premature delivery in 10~30 mm patients with cervical canal length(39.3%)was significantly higher than that in>30 mm.Group A(21.7%),the comparison was statistically significant(P<0.05).Conclusion The measurement of cervical canal length during pregnancy by transperineal ultrasound has a good value in predicting preterm delivery.The shorter the cervical canal length,the wider the cervix internal orifice,which indicates that the probability of preterm delivery is higher.
