摘要
目的探讨伴宫颈缩短的孕妇二胎时宫颈长度与早产率的相关性。方法纳入2010年1月至2017年5月间本院曾生育两胎的孕妇,两次怀孕时均于24～28周使用经阴道超声测量宫颈长度。根据其首次妊娠期经阴道所测量宫颈长度及是否足月生产,分为宫颈缩短足月组、宫颈缩短早产组、正常宫颈足月组(对照组)并对其临床资料和超声测值进行统计分析。结果宫颈缩短早产组和宫颈缩短足月组比正常宫颈足月组更容易在第二胎出现宫颈缩短(P<0. 05)。宫颈缩短早产组第二胎自发性早产率最高(P <0.05),正常宫颈足月组和宫颈缩短足月组第二胎早产率比较差异无统计学意义(P>0.05)。结论伴宫颈缩短的孕妇二胎时易发生宫颈缩短,首胎是否足月是预测二胎早产率的关键因素。
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 chil- dren 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 tri- mester 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 preg- nant 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.
