Acetic acid dressings used to treat pseudomonas colonised burn wounds: A UK national survey.

Wound infection following burn injury can be clinically challenging to manage. Its presence in a thermally compromised patient can detrimentally affect the ability of the wound to heal leading not only to wound progression but ultimately contribute to a large part of the economic health burden expenditure in the National Health Service. Despite meticulous wound care and infection control measures the colonisation of burn wounds by bacterial pathogens has and continues to be the case. There has been a growing interest in the use of antimicrobial applications when managing localised burn wound infections due to a constantly increasing number of antibiotic-resistant organisms. To survey which antimicrobial dressings are currently being used across UK burns services when managing localised pseudomonas wound infections. We conducted a nationwide telephone survey of UK burns services during October 2019 to determine which topical antimicrobial agent was used to treat local pseudomonas burn wound infections. Six burns services (31.6%) used acetic acid-soaked dressings, one of which alternates acetic acid with sodium hypochlorite solution. Silver-based dressings were also used by six burns services (31.6%) - again, one department alternates silver-based dressings with sodium hypochlorite solution. Betadine-soaked, gauze-based dressings were used across five burns services (26.3%) and the remaining two burns services (10.5%) used sodium hypochlorite solution and non-medicated dressings respectively. We identified a significant difference in the UK burns services' approach to pseudomonas burn wound infections. Our literature review demonstrates that a daily dressing regime of 2.5-3% acetic acid is a well-tolerated treatment regime in burn patients and that it is in use in UK burns services. There are no current randomised controlled trials that evaluate the usage of acetic acid. The variation in usage suggests that there is scope for further study in order to develop evidence to generate a UK wide approach based on national standardised guidelines.
