When the skin of the navel is broken and water is flowing, the wound needs to be treated properly and it is recommended to visit the hospital for general surgery or emergency surgery. The doctor first disinfects the wound with iodophor, flushes it with hydrogen peroxide and saline, removes the contaminants from the wound and wraps it with sterile gauze. The treatment needs to be combined with antibacterial drugs, cephalosporins can be chosen, but it should be noted that alcohol should not be consumed while taking cephalosporins to avoid disulfiram-like reactions. It is important to change the medication regularly, and you need to visit the hospital every three days or so to change the medication and observe the changes in the wound. If the exudation in the wound is significantly reduced, it indicates that the inflammation is under control. If the exudation in the wound is increased, it indicates that the inflammation is not yet under control and symptomatic anti-inflammatory treatment needs to be continued. Normally, you should develop good hygiene habits, not to scratch with dirty hands, and use waterproof belly button patches to protect your belly button in the shower.
