Abstract

Deep burn injuries necessitate effective debridement to promote healing and reduce complications. Traditional surgical debridement is the standard of care; however, it can lead to significant tissue loss, excessive bleeding and delayed healing. Bromelain-based enzymatic debridement offers a potential less invasive alternative that aims to selectively remove necrotic tissue while preserving viable ones. Therefore, this systematic review and meta-analysis comprehensively compares bromelain debridement versus standard care in the management of partial and full-thickness burns. Cochrane Library, Embase, and Medline were searched until May 30th, 2024 for studies comparing bromelain debridement versus standard care. R version 4.4.0 was used to pooled risk ratio and mean difference in a random-effects model. We included seven studies, comprising 484 participants, of whom 238 (49%) were treated with enzymatic debridement. Bromelain significantly reduced time to eschar removal (MD - 7.60 days 95% CI [-9.76, -5.44]; I²= 70%) in comparison with standard care. Additionally, bromelain group presented a significant reduction in the risk of surgical excision (RR 0.17; 95% CI [0.06, 0.47]; I²= 79%) and need for autografts (RR 0.40; 95% CI [0.18, 0.93]; I²= 76%) in comparison with standard group. No differences were found in behalf of time to wound closure (MD -7.64; 95% CI [-18.46]-[3.18]; I2 = 86%), nor in Modified Vancouver Scar Scale (MD -0.36; 95% CI [-0.96]-[0.23]; I2 = 0%). Bromelain-based enzymatic debridement may accelerate eschar removal and reduce the need for surgical excision and autografts, without adversely affecting wound closure time or long-term scar quality.
