Studies to date have shown no survival benefit for the use of exogenous surfactant to treat patients with the ARDS. To identify specific patient subgroups for future study, we performed an exploratory post hoc analysis of clinical trials of recombinant surfactant protein-C (rSP-C) surfactant (Venticute; Nycomed GmbH; Konstanz, Germany). ⋯ rSP-C surfactant improved oxygenation in patients with ARDS irrespective of the predisposition. Post hoc evidence of reduced mortality associated with surfactant treatment was obtained in patients with severe respiratory insufficiency due to pneumonia or aspiration. Those patients are the focus of a current randomized, blinded, clinical trial with rSP-C surfactant.
