Care of perianal abscess in infants includes: 1. It is recommended that children be breastfed as much as possible because only breast milk can give the mother’s strong immunity to the baby; 2. Infants and children should wash their bottoms diligently when they are first born, and not a diaper from morning to night. At this time diapers are wet and dirty, not breathable, and children are easily red buttocks. Secondary abscesses may occur slowly. So keep your butt clean, wash it regularly, and change diapers regularly; 3. Prevent diarrhea in children. Because infants and toddlers are rarely constipated, but they may have diarrhea. Some children are born with diarrhea 8-10 times a day, or they may eat inattentively and have acute diarrhea and pull 10-20 times. Once diarrhea occurs, it is recommended to visit the pediatric department of the hospital promptly. Diarrhea must be treated promptly and effectively; otherwise, bacteria may enter the anal sinus and develop a secondary perianal abscess because the anal glands in the intestine remain open and the pressure in the anus is too high.
