Wound dressing refers to the materials used to cover and protect a wound. It helps to keep the area clean, absorb any fluids, and promote healing. Dressings can vary in size, shape, and type, depending on the nature of the wound and the stage of healing. Common types include adhesive bandages, gauze pads, and hydrocolloid dressings. Proper application and regular changing of the dressing are essential to prevent infection and support recovery. Some dressings are designed to be waterproof, while others allow for air circulation. Choosing the right dressing can significantly impact the healing process and overall wound care.
