New Innovations for Deep Partial-Thickness Burn Treatment with ACell MatriStem Matrix

Objective: Burn injuries remain a large financial burden on the healthcare system. According to CDC statistics (2010), nonfatal and hospitalized burns in the U.S. cost $1.8 billion for an annual incidence of ∼486,000 cases. To date, no technique proves to be the ideal therapy of deep partial-thickness burns. In this study, we review a trial usage of ACell (ACell, Inc.) wound matrix on deep partial-thickness burns. Approach: Burn patients were admitted through the Vanderbilt Emergency Department. Three were consented to receive ACell therapy. Each patient suffered extremity burns, to which ACell MatriStem matrix was applied. Time to epithelialization and healing was monitored up to 1 month postintervention. Results: ACell MatriStem matrix use in deep partial-thickness burns enabled healing by 29 days on average without requiring autografts. The average total body surface area (TBSA) of injury was 7.2% with average TBSA treated with ACell equal to 2.5%. All burn sites underwent re-epithelialization after 5.6 days on average (range 4-7 days). Average length of stay after ACell placement totaled 2 days. All patients fully healed without the need for subsequent grafting or contracture development. No postoperative complications were noted. Innovation: To the extent of our knowledge, this is one of the first reported series to utilize ACell MatriStem product in deep partial-thickness extremity burns. Conclusion: Despite numerous products currently available for burn reconstruction, no one product embodies all the characteristics of an ideal graft. ACell biological extracellular matrix scaffolding appears promising, allowing for healing without use of an autograft.
