Brief Summary
Hypothesis: Cortical spreading depolarizations are inhibited by the NMDA receptor antagonist Ketamine Aim 1: To demonstrate, in a group of patients with acute severe brain injury requiring surgery including traumatic brain injury and aneurysmal subarachnoid hemorrhage, whether use of continuous infusion of ketamine decreases frequency of occurrence of cortical spreading depolarizations.

Outcome Measures
Primary Outcomes (1)

Study Arms (2)
Ketamine first
EXPERIMENTALRandomization to receive ketamine as first post-operative sedative in the Neuroscience Intensive Care unit. This group will cross-over to "other sedation" after 6 hours, then alternate every 6 hours between these groups during the entirety of invasive neuromonitoring.
Other sedation (typically propofol) first
EXPERIMENTALRandomization to receive sedative other than ketamine as first post-operative sedative in the Neuroscience Intensive Care unit. This group will cross-over to ketamine after 6 hours, then alternate every 6 hours between these groups during the entirety of invasive neuromonitoring.
Interventions
Ketamine will be used as a sedative alternative to other more conventional sedatives (such as propofol, versed, or dexmedetomidine) in 6 hour blocks of time. Ketamine will be titrated at the bedside based on clinically desired Riker Sedation-Agitation Scale target. Both groups will receive the drug in this multiple crossover design. The only difference between groups is which sedation regimen is started first to minimize any bias related to differences in physiology in the early post-operative phase.
