NCT05493813

Brief Summary

The present clinical trial compares the effect of two general anesthesia (GA) modalities, the one with volatile anesthetic sevoflurane (endotracheal-intubated) and the other integrating total intravenous anesthesia (TIVA) with propofol (non-intubated), on post-procedural delirium and cognitive dysfunction after endovascular thrombectomy (EVT) in the participants with acute ischemic stroke. To assess the outcome of both modalities, the sedation depth of GA will be regulated with processed electroencephalogram monitor to reduce the incidence of postoperative delirium and the peri-procedural blood pressure will be controlled according to the guideline.Based on that, the investigators try to find a better general anesthetic modality for acute ischemic stroke participants undergoing EVT.

Outcome Measures

Primary Outcomes (4)

  • Change in Cognitive function and delirium evaluation

    Cognitive functions (including delirium) will be assessed with the confusion assessment method. It is a validated delirium diagnostic tool, and is considered the "gold standard" for detection of delirium.: The four features of delirium are:1) acute onset and fluctuating course, 2) inattention, 3) disorganized thinking and 4) altered level of consciousness. A positive diagnosis of delirium is made if the person has feature 1 \& 2 plus either 3 or 4. A positive diagnosis of delirium means that the patient's outcome is poor.

Study Arms (2)

Intubated Sevoflurane-GA group

ACTIVE COMPARATOR

After preoxygenation for 3 minutes with 100% oxygen, anesthesia is induced with intravenous injection of propofol (1.5-2 mg/kg), remifentanil infusion (Ce value around 1-1.5 ng/kg), and cisatracurium (0.15-0.2 mg/kg), and followed by endotracheal intubation. General anesthesia is maintained with cisatracuirum (0.03 mg/kg every 45-50 min), remifentanil (Ce value around 1-1.5 ng/kg) and sevoflurane inhalation. Sevoflurane concentration will be adjusted to keep BIS value within the range of 40-60. Mechanical ventilation will be processed at volume-controlled mode with fraction of inspired oxygen (FiO2) 60%, tidal volume 6 ml/kg, and respiratory rate 9-12/min to keep normocapnia and avoid desaturation during the EVT procedure.

Behavioral: Cognitive function and delirium evaluationBehavioral: Neurological functional assessment

Non-intubated TIVA-propofol group

ACTIVE COMPARATOR

With the application of Optiflow nasal high flow set at a flow rate of 20 L/min and 60% FiO2, total intravenous anesthesia is induced with target-controlled infusion of propofol (effect site (Ce) concentration around 1.5-2 μg/ml) and remifentanil (Ce value around 1.0-1.5 ng/ml), and adjusted as required.

Behavioral: Cognitive function and delirium evaluationBehavioral: Neurological functional assessment

Interventions

Cognitive functions (including delirium) will be assessed pre-procedure (baseline) and emergency department (before EVT), on day 1 and 7 and 3 months after EVT procedure

Also known as: Confusion assessment method (CAM)
Intubated Sevoflurane-GA groupNon-intubated TIVA-propofol group

National Institute of Health Stroke Scale (NIHSS) and modified Rankin scale (mRS) will be assessed before (baseline but after stroke) and after EVT on days 1 and 7 after procedure up to 3 months follow-up.

Masking Details
Patients who meet the enrollment criteria and who provide written informed consent will be randomly assigned to either of the intubated Sev-GA or non-intubated TIVA-propofol groups according to either the discretion of anesthesiologist in charge or random allocation. If the patient was in critical situation, uncooperative, or with uncontrolled movement, the anesthesiologist would choose the intubated Sev-GA instead of the scheduled randomization. However, if patient is cooperative and not critical, the patient would be randomly assigned according to the randomization list created with the use of computer-generated, permuted-block sequences. Only the anesthesiologist and physicians involved in EVT are aware of the anesthesia assignment. On the contrary, patients, personnel who collect data, fill out questionnaire and scale measurement, and personnel who assess outcomes are unaware of the group assignments.
