Infected wounds are a common clinical occurrence and can be seen mostly in various surgical departments. According to the conventional treatment, the healing time is often longer, the physician changes the medication more often, and the patient suffers more, so there are often opinions. How to make the wound recover as early as possible is an important issue for clinicians. Creating the conditions for an infected wound to become an acute wound can significantly speed up wound healing. To turn a chronic wound into an acute wound or a near-acute wound, first debride the wound to remove necrotic tissue and reduce the cellular load and bacterial load. The debridement should be moderate, remove all free necrotic tissue, for the wound wall should be properly debridement, should not remove too much tissue, easy to cause bleeding, and at the same time do not expect debridement once to remove all necrotic tissue, generally should be debridement several times. For the wound wall, try to use the method of wiping to achieve the purpose with a little blood leakage from the wound. After debridement, the second step is to perform continuous irrigation and drainage of the wound. Conventional petroleum jelly gauze, various dressings are not satisfactory for drainage. It is not possible to remove the drainage in time. Continuous irrigation and drainage effectively removes bacterial, necrotic, and cellular loads, leaving the wound in a state of flow, significantly accelerating healing time, and bringing the chronic wound closer to the acute wound. Flushing and drainage is usually performed with a double cannula. Acute wound infections, on the other hand, are treated by traditional methods, which tend to turn acute wounds into chronic wounds and must be avoided as much as possible. In short, for infected wounds, try to create conditions that will turn the infected wound into an acute wound and accelerate wound healing.
