[Clinical manifestations and risk factors of poor prognosis of intracranial infection].

To investigate the clinical features and risk factors for poor prognosis in patients with intracranial infection. Retrospective analysis of data of patients who were hospitalized in the First Affiliated Hospital of AnHui Medical University between January 2011 and December 2017, and whose cerebral spinal fluid samples were positive for and who were clinically demonstrated as intracranial infection during hospitalization was performed. Risk factors for poor prognosis were analyzed using single factor analysis and logistic regression analysis. A total of 50 patients were included, with poor prognosis rate of 58% (29/50).92% of patients had history of craniotomy or operation of site adjacent to brain.Major type of intracranial infection was purulent meningitis.Fever rate was 100%.Multidrug resistant accounted for 89.01%. Sensitivity to meropenem was only 9.09%.Shock, multi-drug resistant bacteria and no intrathecal injection were risk factors for poor prognosis of patient.Multi-factor logistic regression analysis showed "no intrathecal injection" was independent risk factor for poor prognosis of patients with intracranial infection. that induced intracranial infection is mostly highly drug-resistant bacterium, with high risk of post-infection poor prognosis.Clinically, it is essential to take proper peri-operative measures and early identify occurrence of intracranial infection.Reasonable application of anti-infection drug and external ventricle drainage, especially intrathecal injection of aminoglycosides, can be promoted as a kind of safe and effective means.
