Clean wound according to manufacturer instructions and clinical protocol. Aseptically remove the MicroMatrix® from packaging. Rinse wound with sterile saline. Apply device to wound surface lightly covering the entire wound. Discard any unused portions of device.
Wet wound: Cover MicroMatrix® with non-adherent moist dressing such as petrolatum gauze, followed by application of an absorptive dressing such as a calcium alginate. Secure dressings to wound site.
Dry wound: Cover MicroMatrix® with non-adherent moist dressing followed by application of a hydrogel dressing to keep wound moist. Secure dressings to wound site. Keep dressing and wound bed moist.
Devices are supplied sterile by electron beam irradiation in a vial or container and a peel-open package. Device is sterile if package is unopened and undamaged.
Inspect wound for adverse reactions every other day; rinse with sterile saline and apply powder to any non-healed areas. As wound heals, it may form a caramel-colored area over wound surface. Gently rinse wound surface leaving caramel-colored area intact. Apply wound dressings according to manufacturer's application instructions. Repeat wound care follow-up every other day until wound healing occurs.
