The use of a collagen sponge/living cell composite material to treat donor sites in burn patients.

The objective of this study was to examine the safety and efficacy of bilayered cellular matrix, (OrCel) Ortec International, Inc., New York, NY in facilitating timely wound closure of split-thickness donor sites in severely burned patients. We utilized a matched pairs design; each patient had two designated donor sites of equivalent surface area and depth. Sites were randomized to receive a single treatment of either OrCel or the standard dressing Biobrane-L (Bertek Pharmaceuticals) Sugarland, TX. The results demonstrate that OrCel was more effective in facilitating timely wound closure of split-thickness skin donor sites than Biobrane-L. The healing time for OrCel sites was significantly shorter than for sites treated with Biobrane-L. This acceleration of wound healing was clinically important in enabling earlier recropping. OrCel sites also exhibited reduced scarring. Therefore, treatment of donor site wounds with OrCel is well tolerated, promotes more rapid healing, and results in reduced scarring when compared with conventional therapy with Biobrane-L.

A premature infant with skin injury successfully treated with bilayered cellular matrix.

The immature skin of premature infants is functionally less effective than the skin of full-term infants and therefore more vulnerable to injury. This article discusses the use of a biologic wound healing agent--bilayered cellular matrix--to heal a denuded hip wound in a premature infant. The treatment involved a compassionate use, single application of an investigational biologic wound healing agent to a 2.0-cm x 1.5-cm hip wound in a 23-week gestational age premature infant. A sterile, nonadherent dressing containing 3% bismuth tribromophenate in a special petrolatum blend on a fine mesh gauze also was applied over the biologic dressing and changed as needed. Wound closure was evaluated by photographs taken before and after the application of the bilayered cellular matrix. Wound measurements were reduced to 1.0 cm x 0.5 cm by day 4 post application of the bilayered cellular matrix, and clean granulation tissue was present. The wound was healed 10 days later. No signs or symptoms of infection were evident during the follow-up period and no adverse events were recorded. Comparative studies are warranted to fully evaluate the utility of bilayered cellular matrix in this clinical setting.

Randomized clinical study of Hydrofiber dressing with silver or silver sulfadiazine in the management of partial-thickness burns.

This prospective, randomized study compared protocols of care using either AQUACEL Ag Hydrofiber (ConvaTec, a Bristol-Myers Squibb company, Skillman, NJ) dressing with silver (n = 42) or silver sulfadiazine (n = 42) for up to 21 days in the management of partial-thickness burns covering 5% to 40% body surface area (BSA). AQUACEL Ag dressing was associated with less pain and anxiety during dressing changes, less burning and stinging during wear, fewer dressing changes, less nursing time, and fewer procedural medications. Silver sulfadiazine was associated with greater flexibility and ease of movement. Adverse events, including infection, were comparable between treatment groups. The AQUACEL Ag dressing protocol tended to have lower total treatment costs (Dollars 1040 vs. Dollars 1180) and a greater rate of re-epithelialization (73.8% vs 60.0%), resulting in cost-effectiveness per burn healed of Dollars 1,409.06 for AQUACEL Ag dressing and Dollars 1,967.95 for silver sulfadiazine. A protocol of care with AQUACEL(R) Ag provided clinical and economic benefits compared with silver sulfadiazine in patients with partial-thickness burns.
