Abstract

Objective: To evaluate the topical antibacterial efficacy of 2.5% mafenide acetate solution on burn wounds in pediatric patients infected with multidrug-resistant bacteria (MDR).
Subjects and methods: A prospective, descriptive interventional longitudinal study was conducted on 29 pediatric burn patients treated at the Intensive Care Unit - Le Huu Trac National Burn Hospital from June 2024 to June 2025. All patients were diagnosed with MDR bacterial infections at the wound site and received topical treatment with 2.5% mafenide acetate solution. Evaluation indicators included local erythema, exudation and bacterial count over time.
Results: After using 2.5% mafenide acetate solution, wound erythema and exudation decreased significantly over time. The bacterial load and positive culture rate decreased significantly (p < 0.001), with no positive cultures observed by day 14.
Conclusion: The 2.5% Mafenide acetate solution demonstrated marked topical antibacterial effectiveness on burn wounds in children with multidrug-resistant infections.
