Abstract

To evaluate the diagnostic value of cerebrospinal lactate for the diagnosis of bacterial meningitis in patients post-neurosurgical operation (PNBM) with blood-contaminated cerebrospinal fluid (CSF). A prospective observational study was conducted. 101 patients underwent neurosurgical operation and clinically suspected PNBM admitted to neurosurgical intensive care unit (NSICU) of the First Affiliated Hospital of Sun Yat-sen University from October 2015 to December 2016 were enrolled. Based on red blood cell quantitative test in CSF, the patients were divided into blood-contaminated and non blood-contaminated CSF groups. According to the PNBM diagnostic criteria of 2008 Centers for Disease Control and Prevention/National Healthcare Safety Network (CDC/NHSN), all patients were divided into PNBM group and non-PNBM group. The biochemical indexes levels in CSF were compared among the groups. Receiver operating characteristic (ROC) curve analysis was used to evaluate the diagnostic power of CSF lactate for PNBM in blood-contaminated patients. A total of 101 suspected PNBM patients were enrolled. In 77 blood-contaminated CSF patients, 39 patients were diagnosed as PNBM (account for 50.6%); in 24 non-blood-contaminated patients, 12 pati...Continue Reading
