Enzymatic debridement with collagenase in wounds and ulcers: a systematic review and meta-analysis

0

Main idea: there is very limited data on the effect of collagenase as an enzymatic debridement technique on wounds. More independent research and adequate reporting of adverse events are warranted.

Abstract

Enzymatic debridement with collagenase is a technique that is commonly used in clinical practice. This systematic review examines the effect of collagenase on all kinds of wounds, compared to an alternative therapy, on wound healing, wound bed characteristics, cost-effectiveness and the occurrence of adverse events. Results support the use of collagenase for enzymatic debridement in pressure ulcers, diabetic foot ulcers and in conjunction with topical antibiotics for burns. However, studies presented a high risk of bias. Risk ratio of developing an adverse event related to collagenase versus the alternative treatment was statistically significant.
