Abstract:
28 patients with acute respiratory distress syndrome caused by 2009 H1N1 influenza were mechanically ventilated for 1 hour in the supine, lateral, semi-supine, lateral prone, and prone position respectively. Changes of heart rate, respiratory parameters and arterial partial pressure of oxygen ( PaO2 )were measured. There were no significant differences ( P > 0. 05 ) of heart rate and mean arterial pressure among these postures. Lateral prone ( P < 0. 05 ) and prone posture ( P < 0. 01 ) , however, can both significantly improve tidal volume, mean airway pressure, PaO2, static lung compliance and oxygenation index. We concluded that mechanical ventilation delivered in the prone position can remarkably improve oxygenation in patients with H1N1 influenza-associated acute lung injury.
