Bacterial nosocomial ventilator-associated pneumonias are common complications in critically-ill patients. The aim of the present study was to determine the significance of the quantitative changes of consciousness of various etiology as a risk factor for the development of this type of pneumonia. ⋯ Suppression of brain activity and the ensuing depressed levels of consciousness as reasons for admission to an intensive-care unit cause a statistically significant increase of the risk of bacterial nosocomial pneumonia developing in patients on mechanical ventilation. Thiopental therapy did not affect the frequency of pulmonary infections. The neurosurgeries we conducted did not increase significantly the risk for nosocomial infections.
