1. Pay attention to the aseptic operation of aseptic wounds, and the covered aseptic gauze should have a certain thickness and range. Infected wounds should also be prevented from re-contamination, and drainage should be kept unobstructed.

2. When dressing the submandibular region and neck, pay attention to keep breathing unobstructed to prevent oppression of larynx and trachea.

3. The pressure should be even and moderate to prevent tissue necrosis due to excessive pressure.

4. The pressure of wound dressing in parotid gland area is moderate, and it can be inserted into the index finger generally, which is elastic to prevent salivary fistula.

5. Cut and drain the wound. The first dressing pressure should be appropriate to help stop bleeding. Don't be too tight in the future to keep the drainage smooth.

6. The pressure of dressing change after plastic surgery should not be too heavy to maintain blood supply. After free skin grafting, the gauze covering the wound should be as flat as possible, with loose gauze and cotton pad, and then properly pressurized and bandaged.
