White granulation inside the umbilical cord may be a normal phenomenon, but it does not exclude pathological factors such as neonatal umbilical cord infection. 1. Normal phenomenon: generally after the umbilical cord of a newborn is detached, there will be newborn granulation tissue proliferation inside the umbilical nest, if no abnormal secretion is found, it is a normal phenomenon. 2. Neonatal Umbilical Cord Infection: There is white granulation tissue inside the umbilical cord after it is detached, gently wipe it with a cotton swab, if purulent secretion is wiped out, it may lead to infection of the umbilical cord, and if the infection is not controlled in time, it may lead to neonatal umbilical cord infection. The umbilical cord will gradually fall off when the newborn is born. If there is purulent discharge after the white granulation tissue in the umbilical node, it is recommended to consult a doctor in time, under the doctor’s guidance, improve the relevant examination, clarify the cause of the disease, and symptomatic treatment.
