Validez de los criterios diagnósticos del síndrome de distrés respiratorio agudo

Abstract

Acute respiratory distress syndrome (ARDS) is defined according to the criteria of the 1994 consensus conference. These criteria aim to <<bring clarity and uniformity to the definition of this clinical entity>>. However, the histological criteria that correspond to ARDS are the criteria of diffuse alveolar damage described in 1976 by Katzenstein et al., which are still valid at present. In the last decade, different studies have been published that have tried to correlate the clinical syndrome with the histological findings. These studies have been basically done in experimental animals, but also by the description of the pulmonary biopsy findings and post-mortem study findings. The present article aims to show discrepancy between clinical and histological diagnosis of the acute pulmonary lesion, basically having an effect on the difficulty of the ARDS diagnosis when its origin is pulmonary and the implications of this discrepancy in the clinical practice and research.
