Summary

The purpose of this study is to investigate how dexmedetomidine affects static and dynamic autoregulation, intracranial pressure (ICP) and cerebral oxygenation in aneurysmal subarachnoid haemorrhage (SAH) patients.

Conditions

  • Subarachnoid Hemorrhage
  • Aneurysm

Interventions

DRUG

Dexmedetomidine infusion

Both static and dynamic autoregulation are assessed first during propofol infusion, before commencement of dexmedetomidine infusion. Dexmedetomidine infusion is commenced with a dose of 0.7 μg/kg/h and propofol infusion is stopped concomitantly. After 2 hours dexmedetomidine infusion, the static and dynamic autoregulation are assessed. If there are no signs of worsening of autoregulation, then the dexmedetomidine infusion is increased to 1 μg/kg/h and after 2 hours the static and dynamic autoregulation are assessed again. However, if autoregulation worsens during dexmedetomidine infusion, it will be stopped and further testing with dexmedetomidine will not be carried out. If autoregulation does not worsen with the 1 μg/kg/h dose then the dose will be increased to 1.4 μg/kg/h. After 2 hours infusion the dynamic and static autoregulation are assessed again. Blood samples for determining dexmedetomidine plasma concentration are collected alongside with the autoregulation assessments
