wound care definition

The core definition of wound care is a systematic health service that covers prevention before wounds occur, full-cycle intervention after injuries, and scar management after healing. It includes debridement, dressing replacement, and wound repair operations completed by medical staff in medical institutions, as well as daily care and risk monitoring in home settings. The ultimate goal is to promote wound healing, reduce complications, and reduce the risk of scarring.

Don’t think this is a vain concept. I met Aunt Zhang at a community free clinic last month. She fell and suffered a slight scratch on her knee. I wore an airtight band-aid at home for a week. When I took it off, the surrounding skin turned white and the wound became rotten. She still spoke plausibly at the time: "Wound care doesn't mean applying some iodophor and putting something on it to keep away the dust? ”This is also the inherent understanding of most people on this matter. They equate it with "emergency treatment after skin rupture", which actually completely narrows its scope.

Speaking of the boundaries of wound care in the industry, there is still no completely unified statement until now. As early as the 1960s, researchers proposed the concept of wet healing, believing that a moist environment can allow epithelial cells to crawl faster and heal twice as fast as dry scabs. Most of those who hold this view are ostomy therapists and wound specialist nurses, who deal with chronic wounds such as pressure sores, diabetic foot, and postoperative refractory wounds on a daily basis. However, many primary care surgeons still believe that ordinary superficial abrasions and cuts can be left dry and scabbed. There is no need to use hydrocolloid or foam dressings, which are expensive and can easily suffocate the wound. In fact, both statements are correct. When I was rotating in surgery, I kept the patients dry before removing the sutures from clean surgical incisions. When I encountered patients with deep second-degree burns, I would change dressings strictly according to the requirements of wet healing. There is no one-size-fits-all standard, and it all depends on the specific conditions of the wound.

What we often call "wound bed preparation" in clinical practice is, to put it bluntly, one of the core aspects of wound care - cleaning the necrotic tissue in the wound, controlling the amount of exudate, adjusting the pH, and paving the way for new granulation tissue to grow. I used to take care of a 70-year-old man with diabetic foot. When he first came here, he had a hole the size of a coin. His family thought it was just an ordinary "bad hole". He applied purple lotion at home for half a month. If his feet were not so swollen that he could not wear shoes, he would not come. When we treated him, we not only debrided him and changed the silver ion dressing every day, but also kept an eye on him to control his blood sugar, and taught his family members how to keep his lower limbs warm and how to observe the color of his toes. It took a full month and a half of medication to heal. You said this wound care only treats the wound itself? It's simply impossible. The patient's general condition and living habits are all factors that need to be taken into consideration.

What many people tend to overlook is that wound care does not start until you are injured. Elderly people who are bedridden for a long time can reduce the occurrence of pressure ulcers by 70% by using pressure-reducing mats in advance and massaging the bony protrusions every day. ； People with scarring constitution can start using tape reduction patches and scar injections as soon as the sutures are removed, which can avoid the appearance of unsightly hypertrophic scars. These actually fall under the category of wound care. A while ago, a parent asked me that if his child had a cut on his face, should he just leave it alone until the scab falls off? I specifically asked her to apply scar removal cream on the child for at least three months and pay attention to sun protection, otherwise the little girl would have a scar on her face and she would be troubled when she grows up.

Nowadays, all kinds of Internet celebrity dressings are boasting so much that the industry has been arguing for several years about whether ordinary families should prepare professional dressings. Some experts think it is completely unnecessary. Keeping some iodine, sterile gauze, and band-aids at home is enough to deal with 90% of small wounds. Some specialist nurses think that if conditions permit, prepare one or two pieces of hydrocolloid and foam dressings, which can indeed reduce the suffering when encountering wounds with a lot of exudation. My own experience is that if you have elderly people or children at home, or you are diabetic or have a scarred constitution, there is really no harm in being prepared. If you rarely get injured, there is really no need to spend that wasted money.

To put it bluntly, wound care is never a rigid operation based on guidelines and formulas. Its definition always changes with specific people and specific wounds. You are right to say that it is a professional medical practice, and you are right to say that it is daily health management. The core has always been only one: to make people suffer less, heal wounds faster, and try not to leave any regrets.
