What is the currently accepted pathophysiologic mechanism of HPS?
YES NO Endotoxin shock X Myocardial depression X DIC X Vasculitis X Pulmonary capillary leak X Vasodilation X Myocarditis X Acute tubular necrosis X Pathophysiologically, pulmonary capillary leakage is the hallmark sign of the presence of this disease. The lung fills with plasma from the capillary causing a decrease in the serum albumin levels and a whitening of the lung field on the chest film. The pathology responsible for most of the fatal outcomes is a myocardial depression that can result in cardiac arrest. Once again a large majority of the respondents answered “not sure” on questions for the pathophysiology section. The majority of providers who had not seen HPS cases answered the following questions incorrectly: endotoxin shock, DIC, myocardial depression, vasculitis, and vasodilation. Providers who had seen patients differed significantly from their fellow providers on the questions regarding endotoxin shock and myocardial depression. Early management of patient with suspected
