Ketamine Boluses Are Associated with a Reduction in Intracranial Pressure and an Increase in Cerebral Perfusion Pressure: A Retrospective Observational Study of Patients with Severe Traumatic Brain Injury

Figure 2

Change in CPP after ketamine bolus according to baseline CPP levels. The blue circles represent patients without paralytic drips, whereas the red circles are those with paralytic drips. The bold lines are the regression lines (black for the whole population and red and blue for those with and without paralytic drips, respectively), whereas the dashed lines are the 95% confidence intervals around the regression lines. The gray zone represents events where the CPP increased according to the regression model the greatest.
