Management of Large Full-Thickness Burns Using Kerecis™ Acellular Fish Skin Graft and ReCell™ Autologous Skin Cell Suspension: A Case Report of Two Patients with Large Surface Area Burns

Novel treatments for extensive full-thickness burns revolve around fluid control, addressing systemic inflammatory derangements, and achieving early skin coverage with acceptable cosmetic and functional results. Recent advances in the management of extensive burns include fish skin xenografts, such as Kerecis Omega-3 acellular dermal substitute. Reported to be non-allergenic and antimicrobial, this Atlantic Cod skin derivative has the potential to supplement the management of patients with large surface area burns. A chart review was performed on two complex patients. Patient 1 suffered 65% partial and full-thickness burns after lighting herself on fire with gasoline, and patient 2 suffered 86% partial and full-thickness burns following a methamphetamine explosion. The patients were both treated with a multi-step process using cadaveric allografts, Kerecis acellular fish skin placement, and autologous split-thickness skin grafts (STSG). Case 2 utilized ReCell autologous skin cell suspension and Novosorb bilaminate dermal substitute (BTM^TM) due to limited donor sites. Complete coverage and epithelization were achieved on both patients but required multiple reapplications of autograft and Kerecis. Contractures of the neck, elbows, and hand were present in Case 1. Kerecis xenografting may have an expanding role in burn management due to standalone capabilities for deep partial-thickness burns and ease of use. Further evaluation is needed to establish the most optimal timing of use and best zones of application to improve take and reduce contractures.
