超声联合测量子宫肌层厚度和宫颈长度预测PPROM孕妇潜伏期

目的探讨超声联合测量早产胎膜早破孕妇的子宫肌层厚度和宫颈长度与潜伏期（胎膜早破至lJ缶产时间的间隔）的关系。方法选择早产胎膜早破孕妇88例作为研究组，选择同期95例未足月正常孕妇作为对照组，超声测量两组孕妇的子宫肌层厚度，部位包括子宫前中部、宫底部、子宫后部和子宫下段肌层的厚度和宫颈长度，记录早产胎膜早破孕妇的潜伏期，比较两组之间子宫各部位的肌层厚度、宫颈长度、孕周与潜伏期的关系。结果两组孕周等一般情况比较无统计学差异。超声测量4个不同部位的子宫肌层厚度在两组之间比较有统计学差异，而宫颈长度在两组之间比较无统计学差异，早产胎膜早破孕妇的潜伏期与4个不同部位的子宫肌层厚度呈正相关与宫颈长度呈正相关，但与孕周呈负相关。结论超声联合测量早产胎膜早破孕妇的子宫肌层厚度和宫颈长度，可以预测其潜伏期，帮助临床医生做出更好的治疗方案。

Prediction of Latency in Women with Preterm Premature Rupture of Membranes Using Sonographic Myometriai Thickness and Cervical Length

Objective To predict latency in women with preterm premature rupture of membranes by ultrasonic measurement com- bined myometrial thickness with cervical length. Methods Eighty - eight women with preterm premature rupture of membranes were en- rolled in this study as case group and ninty - five cases of preterm non - labor pregnancy women were as control group. Myometrial thick- ness at the lower uterine segment, mid - anterior, fundal, and posterior parts of the uterus and cervical length of pregnant women was measured uhrasonographically. Latency was recorded and the relationship between latency interval and myometrial thickness, cervical length, and gestational age in two groups was detected. Results There was a significant difference in myometrial thickness between PPROM group and preterm non - labor control group, but there was no significant difference in cervical length between them. There was a positive correlation between latency interval and myometrial thickness, between latency interval and cervical length. However, there was a negative correlation between latency interval and gestational age. Conclusions Using uhrasonography to detect myometrial thickness and cervical length in women with preterm premature rupture of membranes can predict the latency, which may help clinicians to make a better decision.
