Depending on the severity of the patient’s wound, the method of disinfection with iodine vapor may also differ, as follows: 1. If the patient’s wound is a minor abrasion, the patient’s damage is relatively light, and when disinfecting with iodine vapor, generally with the wound as the center, 2-3 times disinfection can be appropriate to achieve a better effect of removing bacteria from the trauma. After disinfection, sterile gauze or bandages can be used to wrap the wound and disinfect it once in 2-3 days. 2. If the patient’s wound buds are relatively fresh, it is not recommended to use iodophor to disinfect the buds directly. If the patient’s trauma is accompanied by more purulent secretions, iodophor cotton balls can be used to repeatedly clean the local inflammatory exudate, while hydrogen peroxide, vital iodine and saline should be used to repeatedly clean the area to achieve the effect of thorough disinfection.
