Integra™ in burns reconstruction: Our experience and report of an unusual immunological reaction.

Limited availability of autologous donor sites poses significant challenges for soft-tissue reconstruction in severe and complex burns. Integra™ is a bi-layered dermal regeneration template (DRT) which has played a significant role in soft tissue reconstruction since its initial use for full-thickness burn defects. The purpose of this study is to report our institutional experience of Integra™ in burns management over a 4-year period and highlight an unusual reaction to its second application. Twenty-four cases underwent Integra™ resurfacing for burn management from September 2007 to August 2011. Data on patient demographics, including co-morbidities, indications, operative data, complications, secondary reconstruction and outcomes were recorded. Integra™ was used in 24 patients on 37 anatomical sites. One patient died 3 weeks after injury and first stage of Integra™ application, and was therefore excluded from the study. Split-thickness skin grafting was performed within an average of 23 days (with a range of 7-55 days) and mean graft take was 87% (with a range of 75-100%). Five cases of local infection at the graft site were recorded. The average length of hospital stay was 47 days (with a range of 1-162 days). The mean follow-up time was 17 months (with a range of 9-34 months). Overall, our experience with DRT was mixed, that is to say we found it satisfactory with acute burns resurfacing but very good with secondary reconstruction. The main advantage of Integra™ is its immediate availability in unlimited quantities for soft-tissue reconstruction in major and complex burns. The main drawbacks are financial implications, twostage procedure, complex wound care and risk of infection. We believe that Integra™ can be considered as a promising modality in burns management.
