Bowel preparation is essential for colonoscopy.
Split-dose (half the dose the night before and half the dose on the day of colonoscopy) bowel cleanser and no dietary restriction seems to provide better quality colon cleansing than single doses with a liquid diet on the day preceding colonoscopy.
GENERAL MEASURES
Health care professionals should provide both oral and written patient education instructions and emphasize the importance of adherence to the bowel preparation.
MEDICINE TREATMENT
Preparations containing ingredients such as polyethylene glycol (PEG), and sodium sulphate are adequate for bowel cleansing.
- PEG/sodium sulphate, oral, solution.
- 2 litres the night before the procedure and 2 litres the following morning within two hours of the procedure.
Routine use of adjunctive agents (e.g. bisacodyl, senna, prokinetics) for bowel cleansing before colonoscopy is not recommended.
