Brief Title  ICMJE Use of Dexmedetomidine in Acute Stroke and Cerebral Vasospasm Interventions
Official Title  ICMJE A Randomized, Controlled Trial on Dexmedetomidine for Providing Adequate Sedation and Preserved Neurologic Examination for Endovascular Treatment of Acute Ischemic Stroke or Cerebral Vasospasm.
Brief Summary Dexmedetomidine is a unique sedative medication able to provide sedation without causing respiratory depression and maintaining neurological functions. Patients having an acute ischemic stroke and need to undergo endovascular therapy require constant assessment of their neurological status prior, during and after the interventional procedure. In this study the investigators will compare the efficacy of Dexmedetomidine to other standard sedative medications in providing optimal sedative effect while maintaining neurological function.
Detailed Description Precedex is a unique FDA-approved intravenous medication for conscious sedation in that it allows for "arousable" sedation, which is particularly appealing for use in patients with compromised neurologic function. While Precedex has been shown to be equivalent, if not superior to, conventional sedation in the procedural setting, it has not yet been evaluated in the setting of endovascular treatment of acute stroke. This setting is particularly ripe for evaluation, as there is currently controversy over the best method for management of patient sedation in light of the auxiliary need to preserve neurologic function. In order to evaluate the benefit of Precedex in this setting, it must be compared to the usual standard of care. Through the investigators double blinded randomized trial, the investigators will obtain information on the comparison between two arms, one receiving Precedex and the other the usual standard of care at the investigators institution, for achieving and maintaining a pre-defined level of conscious sedation, while preserving baseline neurologic status. This assessment will optimistically serve as the basis for future large-scale studies and ultimately to the establishment of Precedex as a first-line sedative in the management of acute stroke and cerebral vasospasm patients undergoing endovascular intervention.
Study Type  ICMJE Interventional
Study Phase  ICMJE Phase 2
Study Design  ICMJE Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double (Participant, Outcomes Assessor)
Primary Purpose: Supportive Care
Condition  ICMJE
  • Stroke
  • Brain Ischemia
  • Vasospasm, Intracranial
  • Hemorrhage, Intracranial
Intervention  ICMJE
  • Drug: Dexmedetomidine
    Precedex will be given to randomized subjects in thi study to evaluate its efficacy in maintaining optimal sedation and preserving neurological exam.
    Other Name: Precedex
  • Drug: Fentanyl
    Patients in the control arm will receive no medication or standard sedative drug for the interventional procedure.
    Other Names:
    • Sublimaze
    • Fentora
    • Instanyl
  • Drug: Midazolam
    Patients in the control arm will receive no medication or standard sedative drug for the interventional procedure.
    Other Names:
    • Dormicum
    • Hypnovel
    • Versed
Study Arms  ICMJE
  • Experimental: Dexmedetomidine arm
    Precedex will be started after randomization/prior to catheterization and will be stopped at the end of the procedure. It will be used for an average of 90 minutes and will be used as a continuous intravenous infusion started at 0.3 mcg/kg/hour. If HR > 80 and BP > 120/70, a full loading dose (1.0 mcg/kg/hour) will be administered over 10 minutes. If HR is 60 - 80 or systolic BP is 90 - 120, or age > 65 years, a reduced loading dose of 0.5 mcg/kg will be given over 10 minutes. If no volume overload history, 500mL of colloid (hespan or albumin) will be bolused with 0.2mg of glycopyrrolate. Every 10 minutes, Precedex will be titrated by 0.1 mcg/kg/hour to achieve and maintain RASS of 0 to -1.
    Intervention: Drug: Dexmedetomidine
  • Active Comparator: Control arm
    Our usual standard of care is to attempt the intervention without sedation. As per attending physician discretion, Fentanyl (50mcg) and/or Midazolam (0.5 mg) intravenous boluses will be used to control aggressive patient movement that adversely affects the technical capacity of the procedure. The boluses will be repeated at interval of 10 minutes, as necessary. Control arm patients will receive a normal saline placebo drip for the purposes of ensuring patient assessor blindness.
    Interventions:
    • Drug: Fentanyl
    • Drug: Midazolam
