Brief Summary

After a stroke caused by a blockage (clot) in a blood vessel in the brain, patients may have the clot removed by threading a catheter from the groin up to the affected area of the brain. An anesthesiologist is involved in the patient's care during this procedure to maximize patient safety and procedural efficiency. The options for anesthesia for this procedure are general anesthesia (where the patient is unconscious) or sedation (where the patient is in a relaxed, calm, sleepy condition). Currently, it is unclear which of these anesthetic options contributes to the best patient outcome. The investigators would like to investigate whether or not one method of anesthesia (general or sedation) is better to use than the other when removing the clot.

    1 year

Study Arms (2)

General Anesthesia

EXPERIMENTAL

Patients who have had a stroke and meet the inclusion criteria for the study will receive general anesthesia during endovascular treatment. Choice of anesthetic for general anesthesia is dependent upon the patient condition and decision of the treating anesthesiologist (ketamine, propofol, fentanyl, midazolam,dexmedetomidine etc.). General Anesthesia Protocol: (Melinda J. Davis, Cynthia R. Campos-Herrera, \& David P. Archer, 2012; Powers et al., 2015; Talke et al., 2014). Patient will be monitored in accordance with standard monitoring guidelines and the rest of the procedure will proceed in accordance with standard of care. See Detailed Description for additional details and description of follow-up procedures.

Drug: General Anesthesia

Conscious Sedation with Remifentanil

EXPERIMENTAL

Patients who have had a stroke and meet the inclusion criteria for the study will receive conscious during endovascular treatment. Sedation will be accomplished using Remifentanil: 0.01-0.06 micrograms/kilogram/minute, titrated to effect. (Janssen et al., 2016). Patients who have had a stroke and meet the inclusion criteria for the study will receive general anesthesia during endovascular treatment. Patient will be monitored in accordance with standard monitoring guidelines and the rest of the procedure will proceed in accordance with standard of care. See Detailed Description for additional details and description of follow-up procedures.

Interventions

Patients who have had a stroke and meet the inclusion criteria for the study will receive general anesthesia during endovascular treatment. Choice of anesthetic for general anesthesia is dependent upon the patient condition and decision of the treating anesthesiologist (ketamine, propofol, fentanyl, midazolam,dexmedetomidine etc.). Induction of general anesthesia will follow standard treatment methods (Davis et al, 2012, Powers et al. 2015 Talke et al. 2015). Patient monitoring and care will proceed in accordance with standard of care guidelines. Refer to Detailed Description section for complete protocol information.

Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • are greater than 18 years of age
  • considered to be a candidate for endovascular therapy by the London Health Sciences Stroke team
  • presenting within the first 8 hours after symptom onset EXCEPT THOSE for whom general anesthesia is thought to be clearly indicated or contraindicated, by the attending anesthesiologist.

You may not qualify if:

  • Patients in whom the attending anesthesiologist considered that there was a clear indication for either GA or sedation
