Brief Summary:
Acute Respiratory Distress Syndrome (ARDS) and a lesser condition that occurs prior to ARDS, Acute Lung Injury (ALI), are medical conditions that occur when there is severe inflammation and increased fluids (edema) in both lungs, making it hard for the lungs to function properly. Patients with these conditions require treatment that includes the use of a breathing machine (ventilator). The purpose of this study is to find out whether giving albuterol (a drug commonly used in asthmatics) or not giving albuterol to patients with ALI or ARDS makes a difference in how long it takes for a patient to be able to breath without the ventilator.
Detailed Description:
Aerosolized beta-2 agonist therapy is anticipated to diminish the formation of lung edema, enhance clearance of lung edema and decrease pulmonary inflammation in patients with acute lung injury. Because beta-2 agonists have been shown to reduce permeability induced lung injury, it is anticipated that the severity of lung injury will be reduced by aerosolized beta-2 agonist therapy. The therapy may work by enhancing resolution of pulmonary edema by upregulating alveolar epithelial fluid transport mechanisms that will in turn enhance the clearance of alveolar edema. A reduction in the severity of lung injury and the quantity of alveolar edema should result in earlier extubation and more ventilator free days, improved pulmonary oxygen uptake, and improved lung compliance.
Study design: phase II/III prospective, randomized double-blind, placebo controlled trial.
* In Phase II, patients will be treated with aerosolized albuterol 5.0 mg vs. normal saline (n=40-50)administered every 4 hours for 10 days following randomization or until 24 hours following extubation, whichever occurs first. The protocol stipulates that the 5.0 mg dose will be reduced to 2.5 mg if patients exceed defined heart rate limits.
* In Phase III, the 5.0 mg dose will be used unless there is evidence that this dose has an unacceptable safety profile or dose reductions for tachycardia occur in a large fraction of patients. In that case, a lower dose of 2.5 mg will be used.
* Patients will be followed for 90 days or until discharge from the hospital to home with unassisted breathing whichever occurs first.
