Reducing ventilator-induced lung injury and other organ injury by the prone position.
Mechanical ventilation can cause structural and functional disturbances in the lung, as well as other vital organ dysfunctions. Apoptosis is thought to be a histological sign of distant organ damage in ventilator-induced lung injury (VILI). Nakos and colleagues observed a protective effect of prone positioning against VILI in normal sheep. Less alteration in the lung architecture and function and in liver transaminases, and lower indices for apoptosis in the liver, the diaphragm and the lung were noted in the prone position compared with the supine position. If confirmed, these data open a new hypothesis for pathogenesis and prevention of VILI and its extrapulmonary complications.
