At present, the commonly used examination methods: colonoscopy is divided into 1, and ordinary colonoscopy has no anesthetic; 2, painless colonoscopy, using anesthetic, but general hospitals have age restrictions, generally
Preparation before examination: In order not to affect the examination results, red or multi-seed foods, such as watermelon, tomato and kiwi fruit, should be fasted for 1-2 days to avoid affecting colonoscopy. Check the day before lunch and dinner, eat less dregs and semi-liquid food such as porridge and noodles, and do not eat dregs such as vegetables and fruits and dairy products. Fasting on the morning of examination, taking 2 ~ 3L of isotonic solution of polyethylene glycol 4-6 hours before endoscopy, and taking it orally within 2 hours. If you still need to fast at noon in the afternoon, friends without diabetes can drink sugar water to prevent hypoglycemia. Polyethylene glycol is the first choice laxative for intestinal preparation. China guidelines suggest that patients should drink 2-3 liters of water when polyethylene glycol is used for intestinal preparation, and some patients who can't drink a lot of water in a short time are advised to control their diet 1 day before colonoscopy. The most ideal intestinal cleaner is polyethylene glycol preparation, which is a volume laxative. It cleans the intestines by emptying a lot of digestive juice, but it will not affect the absorption and secretion of the intestines, so it will not lead to the disorder of water and electrolyte balance, and the common adverse reactions are abdominal distension and nausea.
In fact, all this is to make the intestine empty, and the cleaner the intestinal wall, the better, so that after the colonoscopy enters, the photos and videos taken can be clearer and the problematic parts can be accurately judged.
I didn't know the importance of health until I got sick. I hope I can stick to a healthy lifestyle and pay attention to my health in the future.
