Pediatric perianal abscesses occur in infants born 1-3 months old due to long-term diarrhea, causing an inflammatory reaction in the skin tissue around the anus, which in turn leads to abscesses. When the outdoor environment is good, it is recommended that infants remove diapers in the sunlight, or use the traditional light bulb baking method to ensure ventilation and dryness around the anus of infants. The specific medication should be combined with the clinical situation and guided by the doctor’s face-to-face consultation.
