title: Acute respiratory distress syndrome (ARDS) in neonates and children.
abstract: ARDS remains a syndrome which despite all efforts poses problems in exact definition (cause, course and severity). Most of the existing information comes from clinical observations and uncontrolled studies and is therefore of limited value. Despite the advent of new treatment modalities mortality from ARDS has remained high and is influenced or caused by several factors like underlying disease, previous health status, presence of MOSF, complications of therapy or ultimate failure of gas exchange. Therapy is directed at elimination of the cause of ARDS if possible, but then mainly supportive, considering all organs and systems. With the introduction of gentler respiratory support techniques (small tidal volumes and pressure limitation, permissive hypercapnia and HFO) and appropriate measures to reduce oxygen toxicity (titration of PEEP, possibly NO), iatrogenic lung injury, indistinguishable from ARDS, can be reduced, and this might improve survival rates. For the future, modulation of the host's inflammatory response may hold great promises for prevention and treatment of ARDS, but such strategies need to be explored with well controlled clinical trials, respecting the complexity of the issue.
