Traditional wound care, which we call “dry wound healing”, has been a concept since the 18th century, when, due to Pasteur’s bacteriological research, the use of dry dressings to cover wounds to keep them dry and avoid bacterial infection became the main wound care principle. In 1962, 3M Dr. Winter’s experiments found that wounds protected by waterproof transparent dressings healed faster. The following year, other scientists confirmed in clinical tests that moist wound healing was much faster than traditional dry wound healing. Since then, “moist wound healing” has replaced “dry wound healing”. The concept of wound care also changed from passive protection of wounds to more active provision of an environment conducive to wound healing. 1, any wound are coated with iodine is not right wound if not very dirty is not needed, because disinfectant water such as hydrogen peroxide, iodine … will destroy the granulation tissue, reduce white blood cell activity, such as must use should be wiped after the superior iodine, immediately rinse with saline. 2, must use antibiotics is not right unless the infection has occurred otherwise do not use antibiotics, even if it is a local antibiotic cream, will also affect the wound healing. 3, the wound to keep dry is not right According to the experiments done by foreign scientists, the wound in a moderately moist environment, its cell regeneration ability and faster migration, recovery speed will be twice as fast than in a completely dry environment. 4, larger or deeper infected wounds to immediately suture is not right wound must be cleaned first, remove necrotic tissue, if there is secretions or deep wounds with cavities, loose gauze or drainage tube must be placed, to be clean and then sewn 5, the wound must be diligent change is not right wound must be in accordance with its nature and the stage of healing, to determine the number of drug changes, the wound as long as it is kept clean, do not need to change the drug every day, because the drug change Instead, it makes the wound susceptible to infection.
