摘　　要：目的 确定超声测量羊膜绒毛膜厚度（AMT）作为预测有症状孕妇早产指标的准确度。方法 以在本院建档就诊的302例单胎孕妇为研究对象,选择有症状组孕22-28周,对照组孕22-23周及孕26-27周时,各测量一次AMT及宫颈长度。记录测量结果,至围产期比较与早产关系。结果 （1）85例有症状孕妇中,平均年龄（29.42±4.24）岁,AMT平均值（1.36±0.35）mm,103例22-23周孕妇平均年龄（29.46±3.67）岁,AMT平均值（1.24±0.20）mm,114例26-27周孕妇平均年龄（29.17±3.74）岁,AMT平均值（1.26±0.20）mm。有症状组与孕22-23周及孕26-27周的AMT比较,年龄无统计学意义,胎膜厚度均有统计学意义。有症状孕妇的胎膜较厚,早产发生率高。（2）有症状组宫颈长度平均（28.1±9.8）mm,对照组孕22-23周平均值（35.1±4.8）mm,孕26-27周平均值（34.6±5）mm。有症状组宫颈短,与对照组比较,有统计学意义。结论 研究证实超声测量有症状孕妇胎膜厚度对预测早产是一个有效的指标,同时对观察正常妊娠胎膜的超声变化有帮助的。Objective To investigate the accuracy of ultrasonographic measurement of amnio chorionic membrane thickness （AMT） in the prediction of preterm birth among pregnant women with symptoms. Methods Three hundred ariel two 302 singleton pregnant women building archives in our hospital between were recruited for the study. The symptomatic group between 22 and 28 weeks, the control groups gestational age was 22 -- 23 weeks and 26 -- 27 weeks. AMT and cervical length were measured and compared with perinatal preterm. Results （1） 85 cases of symp- tomatic pregnant women, average age was （29.42±4.24） ,the mean AMT was （1.36±0.35） mm;103 cases of 22- 23 weeks, average age was （29.46±3.67）, average of AMT was （1.24±0.20） mm;114 cases of 26-27 weeks pregnant, average age was （29.17±3.74）, average of AMT was （1.26 ± 0.20） mm. AMT in Symptomatic group were thicker than in 22-23 weeks and 26-27 weeks, being statistically significant. （2） In symptomatic group aver- age of cervical length was （28.1 ±9.8） mm, the average of the control group was （35.1±4.8） mm in 22-23 weeks and （34.6±5） mm in 26-27 weeks, being statistically significant. Conclusions This study confirmed ultrasono- graphic measurement of amnio chorionic membrane thickness was a valid indicator for prediction of preterm birth a- mong pregnant women with symptoms, while the findings may help for observing changes in fetal membranes in nor- mal pregnancy.
