摘　　要：目的 探讨B超测量子宫肌层厚度能否预测未足月胎膜早破（PPROM）的临产时间。方法 选择2005年9月至2006年1月成都市妇幼保健院住院治疗的PPROM孕妇共28例，破膜后1d内B超测量子宫底部、子宫体前中壁、子宫体后壁和子宫下段肌层的厚度。同期选择相应孕周胎膜完整且未临产的孕妇29例作为对照组。结果 PPROM组子宫体肌层显示出相似的厚度，子宫底部、子宫体前中壁、子宫体后壁组间无差异性（P〉0.05）。PPROM组子宫底部、子宫体前中壁、子宫体后壁和子宫下段肌层的厚度较对照组明显变厚，差异有显著性（P〈0.05）。PPROM组子宫底部肌层厚度与临产明显相关，厚度越厚，临产时间越早，子宫底部肌层厚度〉11mm，5d内临产的敏感性及特异性分别为92.7％，62.0％。结论 B超测量子宫肌层厚度有助于预测未足月胎膜早破的临产时间。Objective To determine whether B sonographic myometrial thickness （MT） predicts the latency interval of women with preterm premature rupture of membranes （PPROM） . Methods 28 women with PPROM in hospital ChengduMaternal and Child Health Care Hospital from Sep 2005 to Jan2006. The ultrasound examination was performed within 24 hours of PPROM. The MT was measured at the fundal, midanterior, posterior and lower uterine segment wall cases and controls with preterm nonlabor intact membranes. Results The MT assessment in the PPROM group uniform thickness at each site of the utreione body （P〉0.05） , But MT was significantly thickness in the PPROM compared with contrals （P〈0.05） .There was a positive relationship between fundal MTand the latency interval： more thicker, more early. A fundalMTmore than llmmwas 92.7%sensitive and 62.0% specific for the identification of PPROM women whose delivery was less than 5 days. Conclusion B sonographicMTmay predict the latency interval of women with PPROM.
