Two patients with burns following petrol sniffing are presented. They sustained an 8 per cent and a 70 per cent total body surface area burn. The majority of the burned areas of both patients were full thickness and were treated by early excision and autografting, and in one patient with cultured epidermal autografts also. Both patients came from disorganized families, had behavioural problems and poor school performance. Clothes soaked with petrol, altered mental state and cigarette smoking are major risk factors for thermal injury while inhaling petrol. In order to recognize acute and chronic intoxication, burns unit staff should be aware of the clinical signs related to inhalation of petrol, especially because some of the burned petrol sniffers might not admit to petrol abuse. The social worker and psychologist are very likely to be vital in the rehabilitation of such patients.
