Umbilical cord velvet occurs in newborns as a result of abnormal proliferation of umbilical cord granulation tissue during the healing process of the severed umbilical stump, which is a fresh pink colored granulation tissue. Once the umbilical cord velvet is detected in a newborn, it needs to be treated immediately. The umbilical fossa of a child with umbilical velvet will have a small amount of discharge, but no fistula or sinus tract. Therefore, if the discharge is high, it needs to be cleaned up promptly. Cure can usually be achieved by topical application of 3% hydrogen peroxide and cauterization of the wound with 1% silver nitrate solution under the doctor’s operation. If the above treatments are less effective, surgical excision treatment is required in infancy. If no action is taken in time, the infection may co-infect and thus develop into umbiliculitis. In order to avoid the appearance of umbilical velvet after birth, newborns should take better care of the umbilicus, keep the area dry and clean, and do not touch it with your hands to avoid adverse stimulation.
