Analysis of the causes of blood in the stool: pediatric blood in the stool, generally considered anal fissure or colorectal polyps, when the child has blood in the stool, and after our physical examination did not find anal fissure, through the finger diagnosis did not find polyps, we often recommend the line of colonoscopy, this time a lot of parents will be very worried about whether the child can do colonoscopy? How to do colonoscopy? General anesthesia has no effect on pediatric intelligence? Let me answer these three questions: pediatrics can do colonoscopy. Many people in many hospitals to consult, the answer is that there is no pediatric colonoscopy, and in fact, the adult colonoscopy can be performed in infants and young children to examine the large intestine, just as our newborn babies can be accommodated in our adult index finger, feel incredulous, but in fact it is completely possible, of course, there is a pediatric colonoscopy is better, and in general, we have adult gastroscopy or nasogastroscopy instead of a pediatric Instead of a pediatric colonoscopy, we usually have an adult gastroscope or nasogastroscope, which makes it relatively safe to perform a pediatric colonoscopy. Pediatric colonoscopies must be performed under anesthesia, otherwise, the exam cannot be completed, except in larger more cooperative children. To be anesthetized, the child must not have a fever or a runny nose, and many children are hospitalized with a runny nose and cannot be anesthetized, resulting in a lot of wasted hospital time and expense. Therefore, when your child is going to be hospitalized for colonoscopy, you must make sure that he does not have fever, runny nose and other cold symptoms. If there is a runny nose and other cold symptoms, the child is anesthetized, the child may be at risk of choking. General anesthesia generally has no effect on intelligence, at least I have not heard of any reports of an effect on intelligence. Blood in the stool treatment: anal fissure mainly through the use of topical drugs, and sitz baths, to keep the bowels open, to avoid the occurrence of constipation or diarrhea, most of the conservative treatment can be cured. Colorectal polyps, pediatric colorectal polyps occur mostly in the distal colorectum, that is, rectum and sigmoid colon, most of them can be resected through colonoscopy can be removed, after treatment, if there is no complication, the child is not in pain, and the recovery is faster.
