Experimental lung research

Recent data suggest that deep hypothermia has protective effects on experimental induced lung injury. It is not well known if these effects persist with mild hypothermia. The authors hypothesized that mild hypothermia may attenuate lung injury and decrease local and systemic proinflammatory cytokines in a rat model of injurious mechanical ventilation (MV). ⋯ There were no differences in terms of PaO(2), histological injury, or BAL protein content. In this model of injurious mechanical ventilation, subjects treated with mild hypothermia had less lung edema and lower plasma IL-1β. Some of known beneficial effects of deep hypothermia can be obtained with mild hypothermia.
