摘　　要：目的探讨超声测量羊膜绒毛膜厚度(Amniotic Chorionic Thickness,AMT)作为预测早产指标的准确性。方法选择以本院建档就诊的100例孕妇为研究对象,在21~22周,25~26周,30~34周均测量一次AMT,记录测量结果,跟踪分娩时间,比较AMT与孕周及早产的关系。结果 100例孕妇在21~22周、25~26周及30~34周均测量AMT分别为(1.17±0.17)、(1.29±0.21)和(1.44±0.29)mm。随着孕周增大,AMT增大,两两比较,P<0.05,均有统计学意义。将早、中、晚3期正常孕周AMT与早产AMT比较,均得出P值<0.05,差异有统计学意义。结论研究证实超声测量AMT简单易行,重复性好,AMT随着孕周增大而增厚,可以预测早产的发生。Objective This study analyzed the statistics of amniotic chorionic thickness(AMT)by ultrasound measurement to investigate the accuracy of AMT as a predictor of preterm labor.Methods In this study,a total of 100 pregnant women who were treated in our hospital were taken as the subject of this investigation.The thickness of the membrane was measured during 21-22 gestational weeks,25-26 gestational weeks and gestational 30-34 weeks,respectively.The relationship among AMT,gestational age and preterm labor has been found by recording the results and tracking delivery time.Results The fetal membrane thickness of 100 pregnant women were measured in 21-22 weeks,25-26 weeks and 30-34 weeks,respectively.The AMT of 100 pregnant women in these three stages were(1.17±0.17),(1.29±0.21)and(1.44±0.29)mm,which were statistically significant(P<0.05).Furthermore,the thickness of fetal membranes increased with the gestational age.There was significant difference between the ATM of the three stages(21-22,25-26 and 30-34 weeks)in normal gestational age and that in the preterm birth(P<0.05).All the difference was statistically significant.Conclusion It is confirmed that the thickness of fetal membranes by ultrasound measurement is simple and reproducible.The thickness of fetal membranes increases with the gestational age,and the occurrence of premature birth can be predicted according to the thickness of fetal membranes.
