BACKGROUND The surfactant system seems to be involved in the pathophysiology of respiratory failure caused by hydrochloric acid (HCl) aspiration. This study was an investigation of the effect of different treatment strategies using an exogenous surfactant preparation on lung function of rats suffering from respiratory failure after intratracheal HCl(More)
The adult respiratory distress syndrome (ARDS) and neonatal respiratory distress syndrome (RDS) are characterized by high permeability pulmonary edema which contains plasma-derived proteins inhibiting pulmonary surfactant function. Currently, discussion continues as to what dose of surfactant is required for treatment of these syndromes. The purpose of this(More)
Objective: To assess whether bronchoalveolar lavage (BAL) with a diluted surfactant suspension prior to surfactant instillation prevents the only transient improvement in lung function as reported after surfactant instillation in severe acute respiratory distress syndrome (ARDS). Design: Randomized, prospective, experimental study. Setting: Laboratory and(More)
Surfactant replacement therapy may be a promising approach for treatment of respiratory failure caused by viral pneumonia. This study in mice demonstrates that during the development of lethal influenza A pneumonia, thorax-lung compliance (Ctl/kg) and lung volume at 5 cm H2O PEEP (V5/kg) significantly decrease (28 and 54%, respectively), whereas lung water(More)
The effect of intratracheal surfactant instillation on pulmonary function in rats withPneumocystis carinii pneumonia (PCP) was investigated. In those animals which developed PCP with severe respiratory failure after administration of cortisone acetate s. c. over 8–12 weeks, pulmonary function was improved by surfactant instillation. PaO2 values 30 min after(More)
Because the surfactant system probably is involved in the pathophysiology of respiratory failure caused by hydrochloric acid (HCl) aspiration, we investigated the effects of different ventilation strategies and intratracheal surfactant instillation at different time intervals on the course of pulmonary gas exchange after HCl aspiration in rats. In this(More)
The effect of intratracheal surfactant administration was studied in rats with adult respiratory distress syndrome associated with infection with nebulized Sendai virus. Thirty-six hours after infection, animals (n = 7) showed severely impaired gas exchange and acidosis during artificial ventilation (PaO2 = 152.2 +/- 18.7, PaCO2 = 65.3 +/- 19.2, pH = 7.26(More)
In this study a model of acute respiratory failure due to viral pneumonia in rats, closely resembling ARDS, is presented. Severe respiratory failure with lethal outcome in four days was induced by infection concentrated Sendai virus aerosol. This model permits evaluation of different therapeutical approaches for improving gas exchange during ARDS.(More)
The role of surfactant-associated proteins in surfactant function was studied by selectively blocking these proteins with monoclonal antibodies. Four monoclonal antibodies, M1, M2, M3, and M4 were identified and their reactivities examined by Western blot analysis. M1, M2, and M4 bind, respectively, 8-, 10- and both 10- and 34-kD proteins. M3 antibody did(More)
Recently a Micro Transmission Cell has been developed based on spectrophotometry for in vivo monitoring of SaO2 together with Hb. A study in pigs was performed to compare the cell with standard methods for measuring SaO2, Hb and Ht. The results show that the cell is capable of following the trends of SaO2, Hb and Ht at different Hb concentrations and/or O2(More)
