【摘要】目的探讨双腔水囊引产器用于晚期妊娠引产的临床疗效,并与普通水囊引产器对比。方法2006年7月至2008年6月需终止妊娠的产妇共76例,随机分为2组:观察组38例,采用双腔水囊引产器引产;对照组38例,采用普通水囊引产器引产。结果双腔水囊引产成功率为97.4%,水囊脱落率为0,总产程平均时间为(28.94±2.76)h。普通水囊引产成功率为84.2%,与观察组相比差异有统计学意义(P=0.047);水囊脱落率为68.4%,与观察组相比差异有高度统计学意义(P=0.000);总产程平均时间为(30.53±3.21)h与观察组相比差异有统计学意义(t=2.32,P<0.05)。结论双腔水囊引产术可明显降低水囊脱落率,提高引产的成功率,且缩短了总产程时间。

【Abstract】ObjectiveTo study the clinical result of induction of labor with double water ballons in third trimester of pregnancy and compared with using single water ballon.MethodsFrom 2006-7 to 2008-6,76 parturient need terminate pregnancy were divided two groups at random.The treatment group(38 cases)was inducted of labor with double water ballons and the contrast group(38 cases)was inducted of labor with single water ballon.ResultsIn the treatment group,the success ratio of induction of labor,drop ratio of water ballon and time of whole labor was 97.4%,0 and (28.94±2.76)hours.In the contrast group,the success ratio of induction of labor,drop ratio of water ballon and time of whole labor was 84.2%,68.4% and(30.53±3.21)hours.There was statistical significant between the two groups.ConclusionThe induction of labor with double water ballons reduce drop ratio of water ballon,increase success ratio of induction of labor and shorten time of whole labor.

水囊引产是将水囊放置在宫壁和胎膜之间,通过增加宫内压和机械性刺激宫颈管,诱发和引起子宫收缩,促使胎儿和胎盘排出的终止妊娠方法。在晚期妊娠引产中,因其促进宫颈成熟,诱发宫缩完成潜伏期宫口扩张的机制,与生理产程改变相似,在临床上应用较为广泛,但普通水囊在引产过程中存在一定的脱落率,降低了引产成功率。我院应用的双腔水囊引产法,克服了这一缺点,降低了水囊脱落率,提高了引产成功率,现将结果报告如下。
1资料与方法
1.12006年7月至2008年6月因各种原因(如计划外生育,高血压,先兆子痫,子痫,过期妊娠等)不适于继续妊娠而来我院引产的单胎,头位,有阴道分娩条件的晚期妊娠产妇共76例,随机分为2组:观察组38例,采用双腔水囊引产器引产;对照组38例,采用普通水囊引产器引产。两组术前主要指标的比较见表1,差异均无统计学意义,其中宫颈成熟度采用Bishop评分法评分。
