2. How to take laxatives

Commonly used bowel preparation drugs include polyethylene glycol, magnesium sulfate, mannitol, etc. Among them, compound polyethylene glycol electrolyte powder is the most widely used type of intestinal cleanser at home and abroad. As a bulk laxative, it cleans the intestines by taking a large amount of liquid orally, has no obvious effect on intestinal absorption and secretion, and does not cause water and electrolyte disorders.

How to take compound polyethylene glycol electrolyte powder:

1. The day before the examination

Take the first dose 1 hour after dinner: Mix 1 box of compound polyethylene glycol electrolyte powder with 1000ml warm water (full measuring cup 1000ml) and finish within 1 hour.

2. Inspection day

Take the second dose 4-6 hours before the test: 1 box of compound polyethylene glycol electrolyte powder + 1000ml warm water (1000ml full cup), take the first cup after 10-15 minutes, and then continue to drink the second cup of compound polyethylene glycol electrolyte powder solution 1000ml. For the last cup of solution, 15ml simethicone (anti-foaming medicine) can be added, and all two cups of solution must be taken within 1 hour.

3. During medication

Fasting, no food or water. Walk appropriately, massage the abdomen clockwise, and defecate at least 8-10 times. Only when the stool is clear and free of residue can the examination be accepted. If the ideal intestinal cleaning quality is not achieved as required, please contact the doctor in the colonoscopy room to take additional intestinal cleaning measures.

How to judge whether bowel preparation is adequate?

The Boston Scale is the most widely used bowel preparation scoring scale. The scale divides the colon into three sections: the right colon, the transverse colon, and the left colon, and scores are performed after suction and infusion. Each section of the colon is scored from 0 to 3 points, with a total score of 0 to 9 points. The higher the score, the better the bowel preparation. A total score of less than 6 points or a score of less than 2 points in any section of the colon is considered inadequate bowel preparation.

A fully prepared bowel preparation must be colorless or yellow transparent watery stool! You can check whether your preparation is qualified by comparing the pictures!
