Abstract:
Objective To investigate the correlation between cervical length and preterm birth rate in pregnant women with cervical shortening.Methods A group of pregnant women who had had two children in our hospital were included.Both lengths of 24-28 weeks were measured by transvaginal ultrasound during both pregnancies.According to the length of the cervix measured by the vagina during the first trimester and whether it is full-term production,it can be divided into the cervical shortening full-term group,the cervical shortening premature delivery group,the normal cervical full-term group (control group),and the clinical and ultrasound measurements are statistically analyzed.Results The cervical shortening in the preterm group and the cervical shortening in the full-term group were more likely to have cervical reduction in the second pregnancy than in the normal cervical full-term group (P < 0.05).The rate of spontaneous preterm birth in the second trimester of the cervix shortened in the preterm group was the highest (P < 0.05).There was no significant difference in the preterm birth rate of the second pregnancy between the normal uterine cervix group and the cervical shortened term group (P > 0.05).Conclusions In the pregnant women with cervical shortening,cervix shortening occurs.Whether the first child is full-term is the key factor in predicting the second premature birth rate.
