Abstract: Objective： To explore the effect of different ways of using simethicone in colonoscopy. Methods： A total of 214 patients undergoing colonoscopy in our hospital from September 2019 to September 2020 were selected and randomly divided into the observation group and the control group， with 107 cases in each group. The control group was given compound polyethylene glycol electrolytes powder and simethicone emulsion 30 mL before colonoscopy， and the observation group was given compound polyethylene glycol electrolytes powder and simethicone emulsion 15 mL before colonoscopy， and the remaining 15 mL of simethicone emulsion was used for spraying during colonoscopy. The cleanliness of the intestines， the intestinal foam condition and the time taken for colonoscopy were compared between the two groups. Results： There was no statistical difference in intestinal cleanliness and the time taken for colonoscopy between the two groups (P>0.05). The intestinal foam condition in the observation group was better than that in the control group， and the difference was statistically significant(P<0.05). Conclusion： The defoaming effect of using half amount of simethicone for bowel preparation before colonoscopy and using the other half amount of simethicone for spraying during colonoscopy is better than using the full amount of simethicone for bowel preparation， which is conducive to clear vision during colonoscopy.
