【摘要】 目的:探讨多普勒超声引导下行痔动脉结扎术(DG-HAL)患者口服复方聚乙二醇电解质行肠道准备的时机。方法:采取前瞻性随机对照的方法,从2010年7月到2011年6月,共有120例接受DG-HAL术的痔患者被随机分成对照组和护理干预组,各60例。对照组术前1天16:00口服复方聚乙二醇电解质,实验组手术当天4:30口服复方聚乙二醇电解质,比较两种方法服药后初次排便时间、自行排便次数、大量不保留灌肠次数;患者手术前晚的食欲、睡眠情况;肠道清洁程度。结果:两组服药后初次排便时间、自行排便次数、排清水样大便时间、大量不保留灌肠次数差异无统计学意义;患者手术前晚的食欲、睡眠情况和肠道清洁程度差异有统计学意义。结论:实验组术日晨口服复方聚乙二醇电解质用于DG-HAL术术前肠道准备,手术前晚食欲、睡眠情况及肠道清洁程度均优于对照组。更多还原

【Abstract】 Objective: To investigate the timing of bowel preparation with polyethylene glycol(PEG) for Doppler-guided hemor-rhoid artery ligations.Methods: In this prospective study,from July 2010 to June 2011,120 patients were randomly assigned to two groups(60 patients per group): to drink PEG solution starting either at 16:00 p.m.before the operation day(control group) or at 4:30 a.m.(experimental group) on the operation day.The primary outcome measure was the time of initial defecation,the numbers of defecation,the numbers of large non-preserved enema,the patient’s appetite,the situation of sleep,and the bowel cleanliness.Results: The time of initial defecation,the times of defecation,and the numbers of non-preserved enema was not different between groups.In the experimental group,the patient’s appetite,the situation of sleep,and the bowel cleanliness were higher than that of the control group.Conclusion: To use the PEG at 4:30 a.m.on the operation day,the patient’s appetite,the situation of sleep,and the bowel cleanliness was higher than that of using the PEG at 16:00 p.m.before the operation day.更多还原
