First dressing change: after circumcision surgery, because there is more blood seepage at the wound, so you need to give the postoperative pressure bandage to stop the bleeding. At this time, it is not recommended to change the medicine too early in order to appear bleeding or edema at the incision, generally 1~2 days between changes in the medicine is better. 2. Subsequent dressing change: After the first dressing change, use iodophor or chlorhexidine and other less irritating disinfectant to disinfect and change the dressing every 1 day. If there is no obvious redness, swelling, heat and pain and oozing at the incision after 1 week of surgery, there is no need to bandage it, but you need to wipe and disinfect it every day. If infection occurs, the dressing needs to be changed once a day until the incision is fully recovered. The specific situation needs to be based on the symptoms of the incision, and the frequency of changing the medicine will be decided by the specialized physician for the condition.
