| Main Objective: The main purpose of this study is to investigate how dexmedetomidine affects static and dynamic autoregulation, intracranial pressure (ICP) and cerebral oxygenation in aneurysmal SAH patients. Dexmedetomidine (dexdor®) is a sedative agent, which got a centralised marketing authorisation from European Commission in September 2011. The static and dynamic autoregulation is first assessed during propofol infusion (before commencing dexmedetomidine infusion) and then during dexmedetomidine infusion. Autoregulation is assessed by means of transcranial doppler (TCD). During propofol infusion and dexmedetomidine infusion the ICP, brain oxygen saturation and brain tissue oxygen tension (PbrO2) (if applicable) are recorded as well. ;Secondary Objective: Please see main objective of the trial.;Primary end point(s): We are interested in whether dexmedetomidine affects the autoregulation of the brain in SAH patients or not. There will be no actual end points.;Timepoint(s) of evaluation of this end point: Please see E.5.1. | — |
