Acute Respiratory Distress Syndrome (ARDS) in critically ill patients with cirrhosis

Journal of Intensive Medicine
Peer-Reviewed Publication

The outcomes of critically ill patients with liver cirrhosis are particularly poor when ARDS develops. Despite this scenario, the robust studies on the prevalence, prognosis, and prognostic factors of ARDS in patients with cirrhosis have remained scarce. To address this, researchers from France carried out a bicentric retrospective study with the largest cohort of patients with cirrhosis and ARDS. The study is the first to identify independent prognostic factors for short-term mortality in this population.
