Medical dressings are materials used to cover and protect wounds, helping to promote healing and prevent infection. They can be made from various materials, including gauze, foam, and hydrocolloids, and are designed to absorb exudate, maintain a moist environment, and provide a barrier against bacteria. These dressings come in different shapes and sizes, tailored to fit various types of wounds, such as cuts, burns, or surgical incisions. Proper application and regular changing of medical dressings are essential for effective wound care and recovery, ensuring that the area remains clean and free from complications.
