Wound packing is a medical technique used to treat deep or complex wounds. It involves placing sterile materials, such as gauze or foam, into the wound to absorb fluids and promote healing. This method helps prevent infection and supports the formation of new tissue. The packing material is usually changed regularly to maintain cleanliness and monitor the healing process. Proper wound packing is essential for conditions like diabetic ulcers or surgical wounds, where the risk of infection is higher. Healthcare professionals often guide patients on how to care for their wounds effectively.
