摘要目的探讨经腹、经阴道和经会阴超声对早产的预测价值。方法选取2015年12月～2017年3月我院收治的120例具有先兆早产症状的孕妇作为研究对象，采用随机数字表法将其分为经阴道超声组、经腹超声组和经会阴超声组，每组各40例。测量并记录三组孕妇的宫颈长度（CL），分析CL与早产的关系。结果以CL 3.0 cm为界，三组孕妇CL＜3.0 cm的早产发生率均显著高于足月产，差异有统计学意义（P＜0.05）。经会阴超声组孕妇的CL测定实现率显著高于经腹超声组及经阴道超声组，经阴道超声组孕妇的CL测定实现率显著高于经腹超声组，差异有统计学意义（P＜0.05）。经阴道组与经会阴组孕妇的CL测定敏感度显著高于经腹超声组，差异有统计学意义（P＜0.05）。经阴道组孕妇的CL测定特异度与阳性率显著高于经腹超声组及经会阴超声组，差异有统计学意义（P＜0.05）。结论经阴道、腹及会阴测量CL可以有效预测早产，且经阴道测量CL的敏感度、特异度、阳性率更高，值得在临床推广。

Abstract：ObjectiveTo investigate the predictive value of transabdominal,transvaginal and transperineal ultrasound for preterm delivery.MethodsA total of 120 pregnant women with symptoms of threatened preterm birth who were treated in our hospital from December 2015 to March 2017 were selected as subjects and divided into transvaginal ultrasound group,transabdominal ultrasound group and perineal ultrasound group by random number table method,40 cases in each group.The cervical length (CL)of three groups of pregnant women was measured and the relationship between CL and premature delivery was analyzed.ResultsThe CL of 3.0 cm was the boundary,the incidences of preterm birth of pregnant women CL＜3.0 cm of three groups were significantly higher than full-term,and the differences were statistically significant(P＜0.05).The fulfillment ratio of CL determination in the perineal ultrasound group was significantly higher than that in the transvaginal ultrasound group and transabdominal ultrasound group,the fulfillment ratio of CL determination in the transvaginal ultrasound group was significantly higher than that in the transabdominal ultrasound group,and the differences were statistically significant(P＜0.05).The sensitivity of CL determination in the transvaginal ultrasound group and perineal ultrasound group were significantly higher than that in the transabdominal ultrasound group,and the differences were statistically significant (P＜0.05).The specificity and positive rate of CL determination in transvaginal ultrasound group were significantly higher than those in the transabdominal ultrasound group and perineal ultrasound group,and the differences were statistically significant(P＜0.05).ConclusionThe transabdominal,transvaginal and transperineal ultrasound to determine the CL can effectively predict preterm birth.The sensitivity,specificity and positive rate of transvaginal measurement of CL is higher,worth in the clinical promotion.
