For children with blood in the stool, parents can deal with the following aspects: 1, give the child a stool routine to test. Because the child causes blood in the stool, often due to bacterial infection. For example, the child has dysentery bacteria or E. coli, these pathogens will cause the child to develop bacterial enteritis, the child will have blood or mucus in the stool. A routine stool test or stool culture will help to confirm the diagnosis of the pathogen and guide the use of medication. For example, if the child is caused by dysentery bacillus, you can give the child timely application of three-generation cephalosporin drugs for anti-infection treatment; 2, need to give the child enteroscopy to diagnose and treat. Because some children’s blood in the stool is recurring, prolonged and difficult to cure, the conventional anti-infective treatment has no effect, this situation needs to be given to the child to do enteroscopy to clearly diagnose and treat. If the child is suffering from intestinal polyps, surgery can be performed at the same time as colonoscopy.
