Under normal circumstances, the umbilical cord can be completely shed 7-10 days after birth, and no later than 14 days. The time for the umbilical cord to fall off is affected by many factors, such as the tightness of the umbilical cord ligature, the location of the umbilical cord ligature, and the thickness of the umbilical cord itself. If the umbilical cord does not fall off after the surface of the cord has dried, it is usually due to adhesions at the root of the cord. A little blood or pus secretion from the umbilical cord may accumulate at the root of the umbilical cord and cause adhesions, resulting in delayed detachment of the umbilical cord. In this case, you need to strengthen the thorough disinfection of the umbilical cord root, you can choose iodine volt for disinfection treatment, 1-2 times a day, and avoid getting wet as much as possible to avoid secondary infection. However, if the umbilical cord does not fall off after more than 14 days, the chances of local infection increase, which may lead to umbiliculitis and, in serious cases, systemic symptoms. Parents are advised to take their babies to the pediatric surgery department of a regular hospital in time for symptomatic treatment by a professional doctor.
