title: Bacterial infections of the central nervous system in neurosurgery.
abstract: CNS infections following clean neurosurgery are uncommon but occur with increased frequency following neurotrauma and placement of CSF shunts and ventriculostomies. When faced with the possibility of meningitis or brain abscess in these settings, the clinician must aggressively seek definitive diagnostic information by means of CT scanning and cell counts, Gram stain, and culture of the CSF. Appropriate empiric therapy should then be administered promptly to achieve cidal activity in the CSF against the most likely infecting pathogens. Prophylaxis for clean neurosurgery and for placement of CSF shunts has been advocated by several investigators. However, regimens are many, and data are few and conflicting. When given, prophylaxis should be administered only during the intraoperative period. There is, at best, a weak scientific basis for what remains a widespread practice.
