Pediatric constipation is one of the problems frequently encountered in pediatric surgery clinics. Some children do not have stool for 3 days, some for a week, or even longer, and parents start to get nervous whether their children have any disease. In fact, most of them are just problems with bowel habits, and they just need to let their children develop good bowel habits without special treatment, which may cause anal fissures, intestinal obstruction, secondary megacolon and other diseases if not corrected in time. What is habitual constipation? Generally, children do not have bowel movements for more than 2 days, their stools are dry, their diet and life are not affected, and there is no abnormality in the abdomen and anus on examination. It can be considered as habitual constipation. Causes: It may be related to the diet now, the diet is too fine and contains little fiber, and then it is related to parents, children go to the bathroom only when they want to defecate, and they do not care whether they are clean or not, so it is easy to form constipation over time. The drier the stool, the less easy to discharge, the more you do not want to discharge, the more you do not want to discharge the more dry, forming a vicious circle, followed by the formation of anal fissures, stool bleeding. Constipation stool characteristics: 1, color: brown or black. 2, shape: straight stick or ball. 3, hardness: hard. If there is no fetal stool for 24 hours after birth, and later often need to use a cecal enema to defecate, attention should be paid to except congenital megacolon. How should we treat it? First of all, if there is blood in the stool and anal fissures, constipation should be relieved first, lactulose or cellulose-containing drugs can be used to promote defecation, while potassium permanganate (1:5000) warm water baths can be used to promote the healing of anal fissures. Defecation habit training: first train to sit on the potty regularly every day (for example, at 7:00 am every day). At the same time, train fast defecation, 5-10 minutes each time, no bowel movement or can not be defecated, you can use an open plug. If the child says he/she is clean, and there is no more stool after injecting the cork, it means he/she is clean. It takes about a year to form good bowel habits, so parents need to be patient, otherwise the previous work is lost. Diet should be more vegetables, fruits, and appropriate coarse grains. Parents should not worry about whether there are side effects of the open plug, there are no side effects. If not used for a long time, it will not produce dependence. For supervising children’s bowel movement, it is necessary to supervise the problem as if they were eating. May every baby no longer suffer from constipation.
