It is best to change the wound every few days.

The purpose of dressing change is to keep the wound clean, check the growth of the wound and see if there are any signs of suppuration. If there is no infection, just clean the wound and its surroundings for disinfection, and then change the dressing. Changing the dressing every day can not only promote the wound healing, but also damage the granulation tissue on the wound because of frequent dressing changes, and it is easy to irritate the wound because of tearing when the gauze is uncovered. Continuous stimulation of the wound will make it difficult to heal, prolong the healing time of the wound and cause excessive proliferation of scar tissue. For common infected wounds with little secretion and good granulation epithelium growth, the dressing can be changed once every 1 ~ 2 days. Wounds with excessive secretions should be changed every day or every other day. For wounds with more pus or exudate, change the dressing 1 ~ 2 times a day. For large and deep wounds, the filled wet gauze strip must be replaced 1 ~ 2 times a day. If necessary, change the soaked outer dressing, so it is not necessary to change the dressing in the wound every time. For the surgical incision, that is, the sterile wound of primary suture, if the patient does not respond, the dressing can be changed until the suture is removed. In case of unexplained fever, pain, bleeding, suspected anaerobic infection, or dressing prolapse, or unclean dressing, increased pus, odor, etc. , should be replaced in time. Whether it is a fresh wound or an infected wound, do not sprinkle anti-inflammatory powder and some colored drugs in the wound during dressing change, so as not to affect the observation of the wound.
