To investigate early onset pneumonia in a neurosurgical intensive care unit, we studied a cohort of patients over a 13-month period and compared neurotrauma (T) with non-neurotrauma (NT) patients. Data were abstracted from the infection surveillance database. Five hundred and sixty-five adults were hospitalized in the neurosurgical intensive care unit. 57.9% had trauma and 129 patients developed 152 episodes of pneumonia. ⋯ EOP was caused by Staphylococcus aureus (33%), Haemophilus spp. (23%), other Gram-positive cocci (22%), and other Gram-negative bacilli (GNB) (19%); whereas after the third day GNB other than Haemophilus spp. accounted for 45.4% of isolates (P = 0.11). This large series confirms the high incidence of EOP in neurosurgical intensive care units, particularly among trauma patients, in relation to risk factors different from those seen in other intensive care patients. Further studies are needed to elaborate specific preventive measures during early care.
