Tomografia computadorizada na insuficiência respiratória aguda

Abstract

O objetivo do presente trabalho é revisar o uso da tomografia computadorizada (TC) na insuficiência respiratória aguda (IRA) - lesão pulmonar aguda ou acute lung injury (ALI) e síndrome da angústia respiratória aguda (SARA). Foram revisados os principais trabalhos publicados na literatura em língua inglesa e localizados por pesquisa na Medline, que estudaram o uso da TC na IRA. A TC permite, num primeiro momento, uma avaliação qualitativa da morfologia pulmonar buscando a presença de hiperdensidades difusas e/ou localizadas e de outras anormalidades concomitantes (como derrame pleural e pneumotórax). Além disso, permite avaliar os histogramas de densidade pulmonares a partir dos quais podem ser efetuados o cálculo dos volumes pulmonares totais e regionais (volume das regiões ventiladas, parcialmente ventiladas, não ventiladas e de hiperdistensão). Isso possibilita quantificar recrutamento alveolar e hiperdistensão decorrentes de estratégias ventilatórias, como por exemplo do uso de diferentes níveis de pressão expiratória final positiva (PEEP).
