OBJECTIVE To investigate the effects of recombinant human activated protein C (rhAPC) on pulmonary function in acute lung injury (ALI) resulting from smoke inhalation in association with a bacterial challenge. DESIGN Prospective, randomized, controlled, experimental animal study with repeated measurements. SETTING Investigational intensive care unit at(More)
OBJECTIVE Acute lung injury is a detrimental complication for victims of burn accidents. Airway obstruction plays an important role in pulmonary dysfunction in these patients. In this study, we tested the hypothesis that aerosolized anticoagulants will reduce the degree of airway obstruction and improve pulmonary function in sheep with severe combined burn(More)
Pseudomonas pneumonia is a common complication of smoke inhalation injury. Airway casts formed from clotted mucous occur frequently in this condition. A recent report shows that intravenous heparin improves oxygenation and reduces lung damage in a sheep model of smoke inhalation. We hypothesized that nebulized heparin could be an effective means of reducing(More)
INTRODUCTION Different isoforms of nitric oxide synthases (NOS) and determinants of oxidative/nitrosative stress play important roles in the pathophysiology of pulmonary dysfunction induced by acute lung injury (ALI) and sepsis. However, the time changes of these pathogenic factors are largely undetermined. METHODS Twenty-four chronically instrumented(More)
Nitric oxide (NO) has been shown to play a major role in acute lung injury (ALI) after smoke inhalation. In the present study, we developed an ovine sepsis model, created by exposing sheep to smoke inhalation followed by instillation of bacteria into the airway, that mimics human sepsis and pneumonia. We hypothesized that the inhibition of neuronal NO(More)
OBJECTIVE Patients with acute lung injury after smoke inhalation often develop pneumonia subsequently complicated by sepsis. This often is a fatal complication. The aim of this study was to develop a standardized and reproducible model of hyperdynamic sepsis after smoke inhalation in sheep. DESIGN Prospective, experimental study in sheep. SETTINGS(More)
More than 20,000 burn injury victims suffer from smoke inhalation injury in the United States annually. In an ovine model of acute lung injury, γ-tocopherol had a beneficial effect when nebulized into the airway. We hypothesize that γ-tocopherol scavenges reactive oxygen species (ROS) and reactive nitrogen species resulting from burn and smoke inhalation(More)
INTRODUCTION Endothelial dysfunction is a hallmark of sepsis, associated with lung transvascular fluid flux and pulmonary dysfunction in septic patients. We tested the hypothesis that methicillin-resistant Staphylococcus aureus (MRSA) sepsis following smoke inhalation increases pulmonary transvascular fluid flux via excessive nitric oxide (NO) production.(More)
Fire victims often suffer from burn injury and concomitant inhalation trauma, the latter significantly contributing to the morbidity and mortality in these patients. Measurement of blood carboxyhemoglobin levels has been proposed as a diagnostic marker to verify and, perhaps, quantify the degree of lung injury following inhalation trauma. However, this(More)
OBJECTIVE Albuterol, due to its bronchodilatory and anti-inflammatory effects, is given via continuous nebulization in children with severe asthma. Combined burn and smoke inhalation injury frequently results in acute lung injury due to a combination of airway obstruction and inflammation. We hypothesized that albuterol administered via continuous(More)
