经会阴B超宫颈评分指标应用价值的探讨

Clinical Application of Cervical Maturity Evaluated by Transperineal Sonographic Technology

目的 探讨经会阴B超宫颈成熟度评分指标的临床应用价值。方法 通过经会阴B超观测宫颈长度、内口扩张度、羊膜嵌入颈管内影像 (HM )对 12 5例孕妇宫颈成熟度进行评分 ,并与其临产时间、分娩方式相比较。结果 宫颈评分≥ 6分者 2 4小时内临产 ,第 1组 0～ 3分 (34例 ) ,第 2组 4～ 6分 (34例 ) ,第 3组≥ 7分 (34例 )的手术产率分别为 70 5 9% ,14 71%及 8 82 % ,0～ 3分组剖宫产率 (5 2 94% )为≥ 7分组 (2 94% )的 18倍。结论 应用宫颈长度、内口扩张度、HM三项指标进行宫颈成熟度评分 ,对临产时间及头位分娩方式有一定提示作用。

Objective To study the clinical value of cervical maturity evaluated by transperineal sonography. Methods Length of cervical canal,amount of cervical dilatation and HM sign were determined by transperineal sonography in 125 pregnant women to evaluate cervical maturity.Compared time in labor and the route of delivery in different cervical score woman. Results Pregnant women without complication were in labor in 24 hours if cervical score is more than 6. women were divided three groups according cervical score.Group 1:score 0～3 is 34 cases.Group 2:score 4～6 is 34 cases.Group 3:score>7 is 34 cases.Respectively,the cesarean section rate is 70\^59%,14\^71%,8\^82% (\%P\%<0\^001).The rate in group 1 is 18 times in group 3. Conclusion Evaluated cervical maturity through length of cervical canal,amount of cervical dilatation and HM sign is important to predict time in labor and decide the route of delivery. [
