A dressing change is a medical procedure that involves replacing the protective covering on a wound. This is important for preventing infection and promoting healing. The dressing helps keep the wound clean and dry while allowing for proper airflow. During a dressing change, healthcare professionals assess the wound for signs of infection, such as redness or swelling. They then carefully remove the old dressing, clean the wound if necessary, and apply a new dressing. Proper technique is essential to ensure the wound heals effectively and to minimize discomfort for the patient.
