In case the umbilical cord does not fall off, the following measures can be taken: first, wait and observe. If the baby’s umbilical cord does not fall off, the localization has been scabbed, there is no redness and pus symptoms, you can observe for a period of time, and most of the cases are able to fall off by themselves. Secondly, local sterilization can be carried out. If the umbilical cord does not fall off due to inflammation of the umbilical cord, and the umbilical cord has redness, swelling and pus oozing out, it is necessary to apply disinfecting medicines such as iodophor to eliminate it in time, so as to prevent secondary infections. Finally, if the non-detachment of the umbilical cord is very obvious and the localized pus is very heavy, the umbilical cord can be re-tied to prevent causing umbilical infection or even sepsis.
