Abstract

Acute respiratory distress syndrome (ARDS) has been associated with high mortality. Improved understanding of the pathophysiology, recognition of precipitating events and improved management has decreased the mortality over the years. Mechanical ventilation is still the corner stone of the management of the disease. It is well recognised that high tidal volumes and airway pressures increase the morbidity, hence the need to use alternative modes of ventilation like pressure control with or without inverse ratio ventilation. Extracorporeal membrane oxygenation is still experimental and not easily available, whereas prone position to improve oxygenation is simple and inexpensive. The concept of pathological oxygen dependency and therapy aimed at supranormal values has failed to improve survival. Restricting the fluids to prevent further oedema formation in an already wet lung has improved the survival rate. Nitric oxide and surfactant have failed to produce desirable effect in large studies. Pharmacological support to inhibit inflammation with non steroidal anti-inflammatory drugs, antifungal agents, prostaglandin and corticosteroids have all failed. Interestingly corticosteroid rescue treatment in the late phase of ARDS has shown promise. Antiendotoxin and anticytokine studies which began with much enthusiasm is yet to produce desirable results.
