![]() Here, we provide an overview of the modern dressings that have been developed for wound healing applications. 10,11 With their advantages, many studies on modern dressings such as foams, hydrogels, alginates, hydrocolloids, and films are carried out to solve clinical problems in treating wounds. 9 Moreover, some types of dressing including alginate or hydrogel dressing have the property non-adhesive to tissues, causing less pain during dressing changes for patients, overcoming the limitation of traditional dressing. On the other hand, modern dressings maintain ideal temperature and humidity for the wound to stimulate wound healing and protect the wound from external bacteria and prevent cross-infection. Traditional wound dressings are often used in clinical practice because they are economical, yet fibers stick to the granulation tissue, causing pain when removing the dressing. 8 Modern dressings are commonly used to cover wounds and generate a moist environment for wound healing. 7 Therefore, with the aging population, the number of patients with chronic wounds is expected to increase and continues to be a long-lasting problem in this population. 6 Chronic wounds are common in elders over 65 years old. 5 According to Medicare, a health insurance program, the cost of wound care for beneficiaries ranges from 28.1 to 96.8 billion dollars per year, with surgical wounds and diabetic ulcers the most expensive, accounting for 38.3 and 18.7 billion dollars, respectively. 3,4 In the United States, injury treatment costs about 50 billion dollars annually. 1 Both acute and chronic wounds have a severely detrimental impact on the world's healthcare systems and economies. 2 Compared to acute wounds, chronic wounds are more difficult to control the wound condition with slow healing time, persistence, and abnormal healing progress and can cause serious complications that require tissue removal. 1 Acute wounds often heal completely and without complications within four weeks, following the expected or predictable rate of healing. ![]() While acute wounds are skin wounds or surgical wounds, chronic wounds are pressure ulcers, leg ulcers, severe burns, and diabetic ulcers. ![]() Based on the time and characteristics of the healing process, wounds are classified as acute wounds and chronic wounds. The last is the discussion about dressing selection in wound treatment and an estimate of the current development tendency of new materials for wound healing dressings.Ī wound is a type of injury that causes a loss of continuity in the skin, tissues, and mucous membranes. In addition, the review also presents the polymer materials for dressing applications as well as the trend of developing these current modern dressings to maximize their function and create ideal dressings. The most popular types commonly used in producing modern dressings are hydrogels, hydrocolloids, alginates, foams, and films. Due to the different types of wounds, as well as the variety of advanced wound dressing products, this review will provide information on the clinical characteristics of the wound, the properties of common modern dressings, and the in vitro, in vivo as well as the clinical trials on their effectiveness. In addition, they also maintain temperature and a moist environment, aid in pain relief, and improve hypoxic environments to stimulate wound healing. Modern wound dressings have been the top priority choice for healing various types of wounds owing to their outstanding biocompatibility and biodegradability. The most common treatment is the use of a dressing to cover the wound and reduce infection risk and the rate of secondary injuries. Wound healing is vital to maintain the physiological functions of the skin.
