Post-neurosurgical meningitis caused by acinetobacter baumannii: case series and review of the literature.

BACKGROUND Acinetobacter baumannii (A. baumannii), a gram-negative bacterium, has now become an important hospital pathogen, which causes various serious nosocomial infections worldwide. Bacterial meningitis is a common complication after neurosurgical operation, and the percentage of A. baumannii meningitis is growing, especially the one resisting multiple drugs. METHOD We retrospectively reviewed the cases with postoperative A. baumannii meningitis (PABM) in the First Affiliated Hospital of Wenzhou Medical University from January 2013 to October 2014. And we retrieved the PubMed for cases with PABM and reviewed them. RESULT Five cases were included in our retrospective study. Two cases with sensitive A. baumannii and one with multidrug-resistant acinetobacter baumannii (MRAB) were cured, and other two with MRAB died. CONCLUSION Intraventricular or intrathecal colistin could be a treatment to the MRAB.
