Abstract

Acute respiratory distress syndrome (ARDS) is a disease of high mortality rate and economic impact. Mechanical ventilation is usually used in patients with this disease, aggravating pre-existing lung damage (ventilation-induced lung injury - VILI). Inflammation is a key attribute to disease progression and resolution. However, the relationship between regional lung inflammation magnitude and shunt severity, ventilation-perfusion ratio, and alveolar damage is not known. Positron emission tomography with 18F-FDG can be used to evaluate the metabolic activity of inflammatory cells in the lung; this procedure is of great clinical relevance since it is considered a noninvasive assessment method. The purpose of this research is to establish a relationship between the kinetic parameters of 18F-FDG and regional severity lung dysfunction and alveolar damage. This study initiates the cooperation between the research group from the Department of Anesthesiology, Pain and Critical Care Medicine - Federal University of Sao Paulo and the Department of Anesthesia, Critical Care and Pain Medicine of Massachusetts General Hospital - Harvard Medical School.
