Pus after circumcision, usually need to apply povidone-iodine disinfection twice a day, observe the recovery afterwards, as the condition improves, the frequency of disinfection can be reduced. Localized pus after circumcision is mostly related to local inflammatory reaction, during which the number of disinfection needs to be increased, and most of them need to be disinfected with povidone-iodine once in the morning and once in the evening, which will help the recovery of inflammation. Afterwards, as the pus gradually subsides and the surrounding inflammatory reaction gradually decreases, you can disinfect only once a day at night before going to bed. Pay attention to closely observe the recovery of the operation area. During the postoperative recovery period, once obvious symptoms of redness, swelling and infection appear, it is necessary to be admitted to the hospital in time for medical observation, and after confirming the diagnosis of the condition, standardized treatment will be carried out under the guidance of the clinician, so as to avoid causing delays in the condition.
