Effect of small water sac of different capacity on the cervical maturity of full-term pregnancy

目的:观察不同容量小水囊对足月妊娠促宫颈成熟的临床疗效。方法:选取120例我院收治的足月妊娠、宫颈不成熟且有需要引产的孕妇,将其分为A组、B组和C组,采取容量分别为30m L、80m L、150m L无菌且装有浓度为0.9%的氯化钠溶液的小水囊以促宫颈成熟。观察并比较三组孕妇的临床疗效。结果:B、C组孕妇的促宫颈成熟有效率、引产后宫颈评分均优于A组(P<0.05);三组产妇产后出血量、新生儿窒息率及体重无明显差异(P>0.05);A、B两组产妇的脐带脱垂状况明显优于C组(P<0.05)。结论:不同容量小水囊对足月妊娠促宫颈成熟均有一定效果,而最佳容量为80m L或150m L,可作为临床的首选方式。
