NHLBI ARDS Network

The late phase of ARDS is often characterized by excessive fibroproliferation leading to gas exchange and compliance abnormalities. The objective of the LaSRS study was to determine if the administration of corticosteroids, in the form of methylprednisolone sodium succinate, in severe late-phase ARDS, would have a positive effect on this fibroproliferation, thereby reducing mortality and morbidity.
