早产预测行超声检测宫颈长度的有效性分析

Study on the Effectiveness of Cervical Length by Sonography in Predicting the Preterm

目的:研究早产预测行超声检测宫颈长度的有效性。材料与方法:回顾性分析2011年1月-2014年12月本院诊治的168例先兆早产以及早产高危孕妇的临床资料,按照超声不同检测方式分为两组,对照组80例受检者行腹部超声检测,研究组88例受检者行阴道超声检测,观察并比较两种超声检测方式对早产预测有效性。结果:宫颈缩短孕妇早产率越高,具体表现为:两组CL<2.60cm与CL≥2.60cm早产、足月产发生率比较差异显著,比较差异均具统计学意义(P<0.05);研究组预测早产准确性显著高于对照组,差异具统计学意义(P<0.05)。结论:超声检测宫颈长度对孕妇早产预测具有重要价值,其中阴道超声检测早产敏感性较腹部超声检测更佳,更值得临床推广及应用。

Purpose： To investigate the effectiveness by applying sonography to detect the cervical length in predicting the preterm. Materials and Methods： 168 cases pregnancy women with high risk factors for preterm birth and threatened preterm birth accepted by hospital from January, 2011 to December, 2014 were divided to two groups according to different way of detection. The control group （80 cases）was detected by transabdominal sonography , while the observation group （88 cases） was detected by transvaginal sonography, compare the effectiveness of two sonography in predicting the preterm. Re- suits： The incidence of preterm birth increase along with the the cervical length becomes shorter, there is a significant differ- ence of preterm birth and full - term rates between two groups by CL 〈 2. 60cm and CL ≥2. 60cm, it shows statistically sig- nificant difference（ P 〈 0. 05 ） ; The accuracy of observation group in predicting the preterm is significant higher than that of control group （ P 〈 0. 05 ）. Conclutlon ： The cervical length measured by sonography is valuable in predicting the preterm of pregnant women, while the sensitivity of transvaginal sonography is higher than transabdominal sonography in predicting the preterm, so it deserve further clinical promotion and application.
