In recent years, the incidence of colorectal cancer in China has been increasing, ranking third in the incidence of malignant tumors. Colonoscopy is routinely performed in asymptomatic populations to screen for colorectal polyps and remove colorectal polyps, thereby reducing the incidence and mortality of colorectal cancer. Colonoscopy is the preferred method for detecting colorectal polyps and precancerous lesions, and its accuracy and effectiveness are closely related to bowel preparation.
The role of compound polyethylene glycol.
Compound polyethylene glycol electrolyte powder is a non-absorbable isotonic intestinal cleanser, which is widely used in clinical practice in China, which stimulates intestinal peristalsis by increasing intestinal fluid volume, so as to achieve the effect of intestinal cleansing and excretion. At the same time, the drug does not affect the body's electrolyte metabolism, does not cause dehydration, electrolyte disorders, etc., and does not affect colonoscopy**, and intestinal preparation is rapid and the cost is low.
The effect of dimethicone oil dispersion.
On the one hand, it can strengthen the discharge of intestinal contents, and on the other hand, it can destroy the surface tension of the bubbles in the intestine more thoroughly and for a longer time, avoid the observation of more bubbles in the intestinal lumen, and play the dual role of cleaning the intestine and improving the clarity of colonoscopy.
Instructions for taking medication for colonoscopy in the morning.
1. How to take the medicine for the first time:
A small amount of food can be eaten at dinner the day before the test. Take 2 boxes orally at 7 p.m. Drink 1500ml (about 3 bottles of 500ml mineral water) with warm water and drink within 60 minutes.
2. How to take the medicine for the second time: Please keep an empty stomach before taking the medicine. 2 boxes are taken orally 6 hours before colonoscopy. Drink 1500ml (about 3 bottles of 500ml mineral water) with warm water and drink within 60 minutes. (If your doctor prescribes dimethicone powder for you, please mix dimethicone powder with the last cup of medicine and dissolve it in warm water for oral use.) After taking the medicine, please exercise moderately to help intestinal peristalsis and facilitate the passage of stool. The standard for bowel cleansing is that the last bowel movement is watery. (The criteria vary from person to person, but 8 to 10 bowel movements are generally appropriate.) ）

Instructions for taking medication for colonoscopy in the afternoon.
After 23:00 on the night before the examination, it is necessary to fasten water until before taking the medicine. 4 boxes were taken orally 6 hours before the examination. Take 3000ml (about 6 bottles of 500ml mineral water) with warm water and drink within 2 hours. (If your doctor prescribes dimethicone powder for you, please mix dimethicone powder with the last cup of medicine and dissolve it in warm water for oral use.) After taking the medicine, please exercise moderately to help intestinal peristalsis and facilitate the passage of stool. The standard for bowel cleansing is that the last bowel movement is watery. (The criteria vary from person to person, but 8 to 10 bowel movements are generally appropriate.) ）
