目的:探讨Creasy高危评分表联合宫颈B超测量预测早产的效果。方法:选择2000～2006年在本院住院的先兆早产孕妇355例及同期在本院门诊进行产前检查的28～36+6周正常孕妇360例,分别采用Creasy评分法、宫颈B超测量法及Creasy评分联合宫颈B超测量3种方法对先兆早产进行预测,比较3种方法的预测敏感度、特异度及孕龄对预测结果的影响。结果:Creasy评分联合宫颈B超测量法的敏感度及特异度均高于单纯采用Creasy评分法或宫颈B超测量法,另外随着孕龄的增加,该法预测早产的敏感度增加,但特异度略下降。结论:在门诊产检过程中可采用Creasy评分联合宫颈B超测量法预测先兆早产的发生,对降低早产的发生率具有较好的效果。
Objective: To investigate the effect of Creasy high-risk score combined with cervical B-ultrasound in predicting preterm birth. Methods: A total of 355 pregnant women with preeclampsia who were hospitalized in our hospital from 2000 to 2006 and 360 normal pregnant women with 28 ~ 36 + 6 weeks of prenatal examination in our hospital during the same period were enrolled in this study. Creasy score, cervical ultrasonography And Creasy score combined with cervical B-ultrasound were used to predict threatened preterm labor. The predictive sensitivity, specificity and gestational age of the three methods were compared. Results: The sensitivity and specificity of Creasy score combined with cervical B-ultrasound were higher than that of Creasy score alone or cervical B-ultrasound. In addition, with the increase of gestational age, the sensitivity of the method predicting preterm birth increased, but the specificity Slight decline. Conclusion: Creasy score combined with cervical B-ultrasound can be used to predict the incidence of threatened preterm birth during outpatient check-up. It has a good effect on reducing the incidence of preterm birth.
