9 In the same way, elevated cerebrospinal fluid (CSF) lactate within the first 10 days following symptom onset correlates with the unfavorable outcome at discharge, not having any correlation between vasospasm and infection in a multivariate model, although there was a trend toward significance in a univariate analysis related to vasospasm. 10 Lindgren et al found no associations at any time between CSF-lactate levels and impaired cerebral circulation or unfavorable outcomes, with CSF-lactate >2.1 mmol/L.
