Abstract | OBJECTIVE: DESIGN: A prospective, controlled, randomised, in vivo animal laboratory study. SETTING: Research laboratory at an university hospital. SUBJECTS: Twenty one (n = 21) adult sheep of either gender weighing 26.8+/-6.4 kg. INTERVENTIONS: MEASUREMENTS AND MAIN RESULTS: PFC aerosol increased oxygenation (PaO2) 15 min after the initiation of treatment up to 120 min (P < 0.05). Transpulmonary shunt improved in the PFC group (P < 0.05) while it did not change in the two other groups. PFC aerosol reduced maximum airway pressure (Pmax) (median) significantly from (median) 38 mbar to 32 mbar (P < 0.05). Static compliance improved significantly in the PFC group (P < 0.05). CONCLUSION: The inhalation of a PFC aerosol led to a significant improvement in pulmonary mechanics and gas exchange, which was not observed in the other two groups. These data suggest that a small dose of perfluorocarbon will have beneficial effects on gas exchange and respiratory mechanics. Therefore, the non-invasive aerosol application technique seems to be a reasonable alternative to administer perfluorocarbons in severe lung injury.
