How to disinfect and change dressings for surgical wounds

Generally, surgical wound disinfection and dressing changes should be performed under sterile conditions to prevent secondary wound infections. The specific steps are as follows:

1. Gently remove the outer dressing by hand, then use a sterile toothless forceps to remove the inner layer of dressing. If the dressing adheres tightly to the wound surface, moisten it with normal saline before removal.

2. Disinfect the skin around the wound using alcohol swabs.

3. Use forceps to hold a cotton ball and clean any exudate from the wound, taking care not to leave any cotton residue inside the wound.

4. Cover the wound with sterile gauze and secure it with adhesive tape. The procedure is now complete.

If a patient's wound heals slowly or shows signs of redness, swelling, or pain, prompt medical evaluation and treatment are recommended to avoid delaying recovery and impairing wound healing. Surgical wound disinfection and dressing changes should be carried out at a reputable medical facility under the guidance of a qualified healthcare professional.
