Abstract
Objective To explore the value of measurement of cervical length by perineal Sonography in prediction of premature labor. Methods 401 cases of regular antenatal examination and institutional delivery in our out-patient clinic were selected, the cervical length through perineal sonography was tested and the pregnancy outcome was followed-up. The cases were divided into mature group, threatened premature labor group, and premature group according to the pregnancy outcome. The relationship between cervical length and pregnancy outcome were analyzed. Results The cervical length in mature group was longer than that in threatened premature labor group, and the cervical length in threatened premature labor group was longer than that in premature labor group. There are significant differences among the three groups(P < 0.05). With the cervical length increasing, the sensibility and positive predictive value became higher. Besides, the specificity and negative predictive value became lower. As the cervical length was ≤ 30mm, the positive predictive values in mature group, threatened premature labor group and premature labor group were 9.7%,32.8%and 92.0% respectively. Conclusion There is a certainly significant value of cervical length through perineal sonography on premature labor. When cervical length of pregnant women with threatened preterm labor symptoms is less than or equal to 30 mm, it has a higher incidence of birth, which can be a warning line of clinical intervention.关键词
