AWBAT(TM): Early Clinical Experience

Objective: The purpose of this article is to describe the early clinical experience with AWBAT. Methods: Burn patients requiring (1) donor sites or (2) treatment of a superficial burn wound injury were treated. A total of 45 patients with 69 distinct wounds were included. AWBAT(TM)-D was evaluated in donor sites and AWBAT(TM)-S was evaluated in superficial partial-thickness burns. Days to healing, pain, hematoma/seroma formation, and infection were noted. Ease of application, adherence, transparency, and physical adaptability details were collected. Results: Average period to healing of donor sites treated with AWBAT-D (n=22 patients with n=26 wounds) was 11.2 days, σ =1.95, with a range of 8–15 days and a median of 11 days. Pain rating at 24 hours was 1.2, σ =0.43 (n=18) and at 48 hours mean was 1.2, σ =0.46 (n=15). Average period to healing of superficial burns treated with AWBAT-S (n=15 patients with n=18 wounds) was 8.1 days, σ =2.48, with a range of 5–13 days and a median of 7 days. Pain rating at 24 hours was 1.5, σ =0.85 (n=10) and at 48 hours mean was 1.75, σ =0.89 (n=8). There was zero incidence of hematoma/seroma. No infections were seen. Results indicate that AWBAT was easily applied with good initial adherence. It was noted to be transparent, conformant, and pliable. Discussion: Early experience demonstrates that AWBAT performs well on donor sites and superficial partial-thickness burns and delivers the desired attributes of a temporary skin substitute including good adherence, infection control, transparency, adapatability, and pain control.
