目的通过就餐与服用泻药间隔时间对内镜检查患者肠道准备效果影响的观察,探讨就餐与服用泻药的最佳时间间隔。方法收集2013年10月至2014年1月于广东省中医院内镜中心行肠镜检查患者的临床资料以及内镜检查时的肠道清洁程度分级情况,按就餐与服用泻药间隔时间分成三组(<5 h、5~8 h、>8 h),分析不同时间间隔对肠道清洁程度的影响。结果共收集418例行肠镜检查患者的资料,其中,就餐与服用泻药时间间隔在5~8 h、>8 h者肠道清洁程度多属Ⅰ级、Ⅱ级,而间隔时间<5 h者肠道清洁程度多属Ⅱ级、Ⅲ级、Ⅳ级。相关分析结果亦提示,就餐与服药时间间隔对肠镜检查时肠道清洁程度有较大影响,就餐时间与服用泻药时间间隔5 h以上的患者在肠道准备方面要显著优于<5h的患者,就餐时间与服用泻药时间间隔8 h以上效果更佳。结论就餐时间与服用泻药间隔时间5 h以上肠道准备效果较好,根据日常实际,推荐5~8h为好。
Objective To observe the effect of laxative interval between meals and gut on the effect of intestinal preparation in patients undergoing endoscopy to explore the best time interval between eating and taking laxatives. Methods The clinical data of patients underwent colonoscopy at the Endoscopic Center of Guangdong Provincial Hospital of Traditional Chinese Medicine from October 2013 to January 2014 were collected. The intestinal cleanliness grade at endoscopy was collected and divided into three groups according to the intervals between eating and taking laxatives (<5 h, 5 ~ 8 h,> 8 h), the effect of different time intervals on intestinal cleanliness was analyzed. Results A total of 418 cases of colonoscopy patients were collected, of which, laxatives between meals and taking 5 ~ 8 h,> 8 h intestinal cleanliness are mostly Ⅰ, Ⅱ, and the interval of <5 h Intestinal cleanliness are mostly Ⅱ, Ⅲ, Ⅳ grade. Correlation analysis also showed that the time interval between meal and medication had a significant effect on the degree of intestinal tract clearance during colonoscopy. Patients who took more than 5 hours between mealtime and taking laxatives had significantly better bowel preparation than those <5h , Dining time and taking laxatives more than 8 h more effective. Conclusion The time of taking meal and taking laxatives more than 5 h intestinal preparation is better, according to daily practice, recommended 5 ~ 8h as well.
