Umbilical velvet is a polypoid growth that appears on the traumatic surface after the umbilical cord is detached. The effects of umbilical velvet on the child mainly include exudate irritation of the umbilical skin leading to localized erosion, which can easily cause inflammation and infection, leading to umbilical cord inflammation and even abscess formation. So once the child’s umbilical cord falls off, you need to regularly and regularly give the child umbilical cord disinfection treatment, under normal circumstances, disinfect 2 times a day. Smaller umbilical antlers can be cauterized with silver nitrate (i.e., drug corrosion), and larger umbilical antlers can be considered for electrocautery treatment or surgical excision and suture.
