Bromelain-based enzymatic debridement of chronic wounds: A preliminary report Academic Article uri icon


  • Sharp debridement is currently considered most effective for debridement of chronic wounds; however, some patients do not have access to or cannot be treated by surgical methods. This study was designed to provide a first impression of the safety and efficacy of bromelain‐based enzymatic debridement of chronic wounds. Two consecutive single‐arm studies assessing the enzymatic debridement efficacy of a concentrate of proteolytic enzymes enriched in bromelain in chronic wounds was conducted in 2 medical centres. Patients were treated with up to 11 consecutive 4‐hour enzymatic debridement sessions and then treated until wound closure. Twenty‐four patients with chronic wounds of different aetiologies were enrolled. All wounds achieved an average of 68% ± 30% debridement in an average of 3.5 ± 2.8 enzymatic debridement 4‐hour sessions. Seventeen responding wounds (venous, diabetic, pressure, and post‐traumatic aetiologies) achieved an average 85% ± 12% debridement in 3.2 ± 2.5 applications. Seven non‐responding wounds (arterial and post‐surgical aetiologies) achieved an average 26% ± 13% debridement in 4.3 ± 3.5 applications. No treatment‐related serious adverse events were observed, and the only adverse event attributed to the enzymatic debridement was pain. These preliminary results indicate the potential safety and efficacy of bromelain‐based enzymatic debridement in chronic wounds. Larger controlled studies are needed to further investigate this indication.
