title: Effects of ibuprofen on pulmonary oedema in an animal smoke inhalation model.
abstract: The ability of ibuprofen to lower extravascular lung water significantly was examined in an animal smoke inhalation model. Adult New Zealand White rabbits weighing 3-5 kg were anaesthetized and intubated. They were then allowed to breathe cooled cotton smoke until the carboxyhaemoglobin (COHb) reached a level of 60 per cent or higher. Each ibuprofen-treated animal received a dose of 50 mg/kg either intraperitoneally or intravenously. Ibuprofen was administered to animals that received smoke inhalation alone and those that received smoke inhalation combined with a 10 per cent BSA partial skin thickness thermal injury. Control groups were established for both of the above-mentioned groups. Peak carboxyhaemoglobin levels as well as CO half-lives were not significantly different between ibuprofen-treated groups and the controls. Ibuprofen treatment resulted in significantly (P less than 0.05) decreased lung water in both smoke, and smoke plus thermal injury groups as compared to controls. These results suggest that ibuprofen promotes the reduction of early-onset lung water resulting from smoke inhalation injury alone or from smoke inhalation injury plus a thermal injury.
