Restore Calcium Alginate Dressing, Silver vs Aquacel Ag in the Treatment of Critically Colonized Venous Leg Ulcers

Restore Calcium Alginate Dressing, Silver vs Aquacel Ag in the Treatment of Critically Colonized Venous Leg Ulcers

Calcium alginate dressings with silver have been found to be safe and effective for use for leg ulcers. The primary objective is to compare Restore Calcium Alginate Dressing, Silver to AqualCel Ag Dressing on the following parameters: No further progression toward infection (bioburden), ease of application and removal, and percent progression to closure. The secondary objective is to obtain photographic documentation of the leg ulcers during the course of the study.

Inclusion Criteria:

2. Previous diagnosis of venous insufficiency proven by a positive venous duplex with reflux.

3. Has a venous ulcer with a wound area between 5 cm2 - 40 cm2.

4. Has an ankle brachial index (ABI) >0.8.

5. Has a venous ulcer with duration less than 24 months.

6. Has a venous ulcer which is critically colonized (not infected) based on the Lazareth Study Model. Ulcers are considered to be critically colonized if at least three of the five following signs are present:

7. Is currently using Profore as their standard of care.

8. Has not received antibiotics for 6 weeks prior to enrollment.
