摘要
目的 采用会阴部超声进行宫颈检查 ,研究宫颈长度与早产临产间隔时间长短的关系。方法 选择自然临产的 2 8~ 36 + 6孕周的孕妇 ,应用会阴部超声测量宫颈长度 ,并记录测定时间 ,在临产后计算出测量与临产间隔的时间。结果 选择我院 1998年 1月~ 2 0 0 1年 12月 16 2例早产孕妇 ,分为胎膜完整组 77例 ,胎膜早破组 85例。宫颈长度为 0~ 10mm时 ,距临产时间为 (17.6 3± 2 7.93)h ;11~ 2 0mm为 (5 7.97± 83.78)h ;>2 0mm为 (15 3.6 9± 139.4 8)h。宫颈长度越长 ,距临产的时间也愈长 (P <0 .0 1) ,胎膜完整组与胎膜早破组的差异无显著性。结论 宫颈长度与临产间隔时间有明显的关系 ,宫颈长度越长 ,距临产间隔时间也越长 ,但与胎膜是否早破无关。
Objective Transperineal ultrasonography was used to measure the cervical length and to assess its relationship with the time interval of onset of labor in threatened preterm patients with intact or ruptured membrane. Methods The patients with threatened preterm labor and/or preterm premature ruptured membrane between 28~36 +6 gestational weeks, were examined by transperineal ultrasonography. The cervical length, the time of examination and the time of onset of labor were recorded and analyzed. Results Among 162 cases of preterm delivery, 77 possessed intact membranes and 85 had premature rupture of membrane. The time intervals between the examination and onset of delivery were 17.63, 57.97 and 153.69 hours in cervied lengths of 0~10 mm, 11~20 mm and >20 mm groups, respectively, the longer the cervical length, the longer interval time was observed ( P <0.01). Whereas the outcomes in the group of intact or ruptured membrane revealed the same. Conclusion There is a significant relationship between cervical length and time interval of onset of labor interval, no matter the membrane is intact or ruptured.
