ABSTRACT
BACKGROUND AND OBJECTIVES: 'Frosties' are deliberate cold skin burns caused by an aerosol device. The aim of this article was to examine our own cohort, and those previously published, to identify the key features of patients presenting with frosties and inform appropriate early clinical interventions. METHOD: We compared cases in our dataset that occurred between 1 January 2013 and 30 June 2017 with those reported in the literature, focusing on seven domains: sex, age at injury, days to presentation, first aid, depth of injury and outcome. RESULTS: The median patient age was 13 years; 70.5% were female. Adequate first aid was not reported in any patient. Where recorded, the median time to presentation to a health service was six days. Where severity of injury was recorded, 13 of 37 cases (35.1%) were full thickness, and 10 patients received a split thickness skin graft. Two subgroups were identified: cluster injuries and psychological distress. DISCUSSION: Cluster injuries occur as the result of a mutual 'test of courage'. Solo injuries may point to underlying psychological distress. Frosties frequently result in significant burn injuries and often require skin grafting. The severity of frosties is underappreciated and, as a consequence, treatment, through first aid or presentation to a health service, is delayed or absent. General practitioners should be familiar with the appearance of frosties in order to identify them in unrelated consultations.
