Use 9 x 9 inch dressing on lower back for a wide range of acute and chronic wounds such as venous leg ulcers, pressure ulcers, diabetic ulcers and traumatic wounds; its heart-shape works well for the sacral or coccyx area. Tapered edge allows dressing to lie smoothly. Perforated silicone gel adhesive provides gentle but firm adhesion. Dressing affixes securely to dry, intact skin; seals the wound margins to help prevent exudate from leaking on surrounding tissue, minimizing risk of maceration.
