Acute respiratory distress syndrome

Area of Science:

• Critical Care Medicine
• Pulmonology
• Respiratory Medicine

Background:

• Acute respiratory distress syndrome (ARDS) is a severe clinical condition characterized by hypoxia and bilateral pulmonary infiltrates.
• It is diagnosed in the absence of heart failure as the cause.
• Current management is primarily supportive.

Purpose of the Study:

• To summarize the key aspects of ARDS diagnosis and management.
• To highlight effective and contraindicated therapeutic strategies.
• To provide an overview of ARDS outcomes.

Main Methods:

• Review of current clinical guidelines and evidence for ARDS management.
• Focus on supportive care strategies like mechanical ventilation and fluid balance.
• Evaluation of specific interventions for severe hypoxemia.

Main Results:

• Protective mechanical ventilation and avoidance of fluid overload are central to ARDS management.
• Early short-term neuromuscular blockade, prone position ventilation, or extracorporeal membrane oxygenation (ECMO) are options for severe hypoxemia.
• Inhaled nitric oxide, β2 agonists, and late corticosteroids are generally not indicated and should be avoided.

Conclusions:

• ARDS management is primarily supportive, emphasizing lung-protective strategies.
• Specific interventions exist for severe cases, but careful patient selection is crucial.
• Mortality for ARDS remains significant, at approximately 30%.
