Novel approaches in conventional mechanical ventilation for paediatric acute lung injury.
Acute lung injury remains a major cause of morbidity and mortality in paediatric intensive care units. Research over the past decade has altered our understanding of the pathophysiology of acute lung injury and the effects of mechanical ventilation on the lung. As a result, approaches to conventional mechanical ventilation of the injured lung are now largely centred around preservation of adequate gas exchange while protecting the lung from further ventilator-induced lung injury. Current techniques for accomplishing these goals include adjusting the ventilator based on the measurement and interpretation of pressure-volume curves, limitation of inspiratory tidal volumes, use of elevated levels of positive end-expiratory pressure, recruiting manoeuvres and prone positioning. The currently available data regarding the efficacy and appropriate use of these techniques are reviewed.
