Wound care has witnessed significant advancements, transitioning from traditional to modern approaches, which have revolutionized the management of various types of wounds. These advancements have improved outcomes, accelerated healing, and enhanced patient comfort. Traditional wound care focused on basic principles such as wound cleansing, debridement, and dressing application. While these principles still hold value, modern approaches have introduced innovative techniques and products. One notable advancement is the use of advanced dressings. These dressings are designed to create and maintain a moist wound environment, promote angiogenesis and granulation tissue formation, and facilitate autolytic debridement. They can include films, hydrogels, foams, hydrocolloids, and composite dressings, among others.
Another breakthrough is the application of growth factors, which stimulate cell proliferation and tissue regeneration. Growth factors like platelet-derived growth factor (PDGF) and epidermal growth factor (EGF) can be used topically or through advanced therapies such as platelet-rich plasma (PRP) or bioengineered skin substitutes. Furthermore, the advent of negative pressure wound therapy (NPWT) has transformed wound care. NPWT involves the application of controlled negative pressure to the wound, promoting granulation tissue formation, reducing edema, and enhancing wound contraction. Moreover, the emergence of bioengineered tissues and cellular therapies has provided new options for complex or chronic wounds. These therapies involve the use of skin substitutes, tissue-engineered matrices, and stem cells to promote healing and tissue regeneration.
