Hydrocolloid: primary or secondary dressing for wounds with light to moderate exudate. Helps maintain a moist wound environment to assist in autolytic debridement. When in contact with wound exudate, it forms a fluid/gel environment over the wound bed. Dressing does not break down or leave residue in the wound. Thin and film back versions feature a smooth, tapered design to help minimize friction and prevent dressing edges from rolling up. Thin Hydrocolloid is semi-transparent, allowing visualization of the wound. Contains a semi-transparent layer that permits wound evaluation without removing dressing. Moisture-resistant backing helps prevent urine, feces or moisture from penetrating the dressing to reduce risk of contamination.
