摘要
目的探讨经会阴超声动态监测宫颈管长度缩短率与早产的关系。方法选择有早产症状的初产妇298例，每天经会阴测量1次宫颈管长度，计算宫颈管长度缩短率。然后观察不同宫颈管长度缩短率≤15％组，16％～30％组，31％～60％组，〉60％组，第1、2周及第3周内的早产率的情况。并计算3周总的早产率。结果当宫颈管长度缩短率≤15％时，早产可能性极低。随着宫颈管缩短率的上升，早产率也明显增加，当宫颈管长度缩短率16％～30％和31％-60％时，早产率分别为3．4％和7．9％，两组早产率比较差异有统计学意义（P〈0．05）；当宫颈管长度缩短率〉60％组时，早产率为48％，与其他组早产率之间比较差异有统计学意义（P〈0．01），即宫颈管长度缩短率越大，早产率越高。结论宫颈管长度缩短率可作为早产的预测指标，且宫颈管缩短率与早产率呈正比。
Objective To investigate the relationship between the cervical canal length shortening rate and preterm delivery by perineal ultrasound dynamic monitoring. Methods Two hundred and ninety-eight cases of preterm symptoms primipara were selected, transperineal measuring cervical canal length every day to calculate the length of the cervical canal shortening rate. And then observe the preterm birth rate of the cervical canal length shortening rate ≤ 15% group, 16% -30% group, 31% - 60% group, 〉 60% group at the first week, second week and third week respectively. And calculate the total of preterm birth rate of the three weeks. Results When the cervical length shortening rate ≤15% , premature birth was highly unlikely. With the cervical canal shortening rate increased, the preterm birth rate also increased significantly, when the cervical canal length shortening rate of 16% -30% and 31% -60% group, the preterm birth rate were 3.4% and 7.9% , the difference of preterm birth rate was statistically significant（ P 〈0. 05 ） between the two groups. When the cervical length shortening rate 〉 60% , premature birth rate was 48%. The differences were statistically significant compared with other groups（ P 〈0.01 ）. Cervical canal length shortening rate was the greater, the higher the preterm birth rate. Conclusions The cervical canal length shortening rate can be used as a predictor of preterm birth, the shortening rate is proportional to the preterm birth rate.
