ABSTRACT
This study is to explore the application value of fractional administration of compound polyethylene glycol electrolyte powder combined with simethicone for bowel preparation before colonoscopy in elderly patients.
The objects are 60 elderly patients who underwent colonoscopy in our hospital in 2021.The patients were randomly divided into the control group and the observation group, 30 cases in each group. The control group took polyethylene glycol electrolyte powder for bowel preparation by several times. On this basis, the observation group was given simethicone for bowel preparation. The adverse reactions, intestinal cleanliness, air bubbles in the intestines, lens clarity, time of entering the lens, the amount of saline flushing, and lesion detection were compared between the two groups.
There was no significant difference in adverse reactions, bowel cleanliness score, detection rate of ≥0.5 cm polyps and adenomas between the two groups(P>0.05), but the air bubbles and lens clarity , the time of entering the lens, the amount of saline flushing, the detection rate of<0.5 cm polyps of the observation group was significantly better than that of the control group(P<0.05).
It is safe and effective for elderly patients to take compound polyethylene glycol electrolyte powder combined with simethicone for intestinal preparation.
