Fibroblast growth factor in the treatment of burns: A systematic review.

INTRODUCTION

A burn is a trauma that breaks the skin barrier, causing local and systemic responses. Treatment is complex, multiprofessional and expensive. In addition to surgical treatment, topical dressings can be used to keep the wound moist, reduce the risk of infection and stimulate healing. Clinical studies show that topical use of fibroblast growth factors may accelerate healing. An assessment of the quality of the available evidence and its strength of recommendation is necessary.

OBJECTIVE

This study aimed to evaluate the effectiveness and safety of topical use of fibroblast growth factor, compared to other topical treatments or placebo, in the healing of burns, to determine the strength of recommendation.

METHOD

Based on a defined search strategy, randomized and quasi-randomized clinical trials, available in electronic databases, were gathered. These compare the topical use of FGF versus other topical or non-treatment. The primary outcome was healing and as adverse effects: pain, infection and mortality. The systematic review protocol was registered on the PROSPERO platform (CRD42018089556), developed in accordance with the "Preferred Reporting Items for Systematic review and Meta-Analysis Protocols (PRISMA-P) 2015" and within the "SWiM guideline 2019". GRADEpro was used for the critical analysis of the methodology of the studies.

RESULTS

Four clinical trials were found, in which FGF reduced the healing time and improved the appearance of the scar. Two trials were determined to be of low strength, while two others have a moderate recommendation strength.

CONCLUSION

This review gathered available evidence, between low and moderate recommendation strength for the use of FGF as a topical dressing. Further rigorous trials are needed to improve the strength of recommendation for topical use of FGF for burns.
