摘要
目的:探讨潜伏期利多卡因宫颈封闭联合人工破膜对产妇产程的影响。方法:将204例足月、宫颈口开大2 cm且无严重妊娠合并症、并发症的初产妇随机分为观察组与对照组各102例。观察组在潜伏期采用利多卡因宫颈封闭后行人工破膜。对照组按产科常规处理,不采取干预措施,等待产妇自然破膜及分娩。结果:观察组潜伏期平均时间为4.25±1.23h,活跃期平均时间为2.56±1.03h,第二产程平均时间为0.52±0.17h,缩宫素静脉滴注率17.65%,剖宫产率为25.49%;对照组潜伏期平均时间为8.62±5.23h,活跃期平均时间为3.92±2.21h,第二产程平均时间为1.03±0.31h,缩宫素静脉滴注率为31.37%,剖宫产率为39.22%。两组比较均有显著性差异(P<0.05,P<0.01)。结论:潜伏期利多卡因宫颈封闭联合人工破膜,有利于加速宫颈口扩张,缩短产程,降低难产发生率。此方法既简单又经济、安全,值得临床推广应用。
Objective： To explore the effect of cervical blocking with lidocaine in latent period combined with artificial rupture of fetal membranes on labor progress. Methods ： Two hundred and four primipara who were in term pregnancy with orifice of cervix opening in 2 cm and had no severe complications were randomly divided into observation group （ n = 102 ） and control group （ n = 102）. The primipara in observation group were given cervical blocking with lidocaine and then fetal membranes were ruptured artificially, and routine measures without any intervention was taken till primipara had spontaneous labor in control group. Results： The average latent time was 4.25 ± 1.23h and average active time was 2.56 ± 1.03h, the average time of the second labor course was 0.52 ±0.17h, the rate of intravenous drip was 17.65% and cesarean section rate was 25.49% in observation group ; That was 8.62± 5.23h, 3.92 ± 2.21h, 1.03 ±0.31h, 31.37% and 39.22% respectively in control group. The significant differences were found in the comparison between the two groups （ P 〈0.05, P 〈 0. 01 ）. Conclusion： It can speed up opening of orifice of cervix to adopt cervical blocking in latent period combined with artificial rupture of fetal membranes so that labor course will be shortened and incidence of dystocia be decreased. It is regarded as one of simple, economical and safe methods.
