The effect of intratracheal surfactant instillation on pulmonary function in rats with pneumocystis carinii pneumonia (PCP) was investigated. In these animals which developed PCP with severe respiratory failure after s.c. administration of cortisone acetate over 8-12 weeks, pulmonary function could be improved by surfactant instillation, as measured by an increase in PaO2. Histological examination showed that alveoli of rats with PCP which received no surfactant treatment are filled with foamy edema, whereas after surfactant treatment alveoli are stabilized and well-aerated. These results indicate that surfactant therapy could be used in patients with severe PCP to overcome an acute stage of respiratory distress while at the same time surfactant could serve as a carrier substance for antimicrobial drugs to attain high intra-alveolar and low systemic antimicrobial drug concentrations.
