If a patient has pus coming out of the navel, it means that an abscess has started to form, and it should be treated with timely incision and drainage and drug changes. If the pus is large and causes peritonitis or sepsis, an adequate amount of broad-spectrum antibiotics should be given for treatment, and appropriate antibiotics should be selected and administered intravenously according to the bacterial drug sensitivity test of the pus. If the patient has pus in the navel and causes systemic infection, the patient’s water and electrolyte balance should be adjusted in time to improve the immunity of the patient’s body, and sometimes some albumin can be infused for treatment.
