NCT03317535

Brief Summary

There is few randomized controlled clinical to investigated the impact of anesthetic type on outcome in patients with acute ischemic stroke in posterior cerebral circulation. It is unknown whether the choice of anesthesia is impacted on the outcomes for these patients or not. The investigators will perform a randomized controlled pilot clinical trial of general anesthesia versus local anesthesia/conscious sedation to explore and find out a potential fact whether anesthetic type alters perioperative neurological function in patients with acute ischemic stroke in posterior cerebral circulation.

Outcome Measures

Primary Outcomes (1)

  • modified rankin score(mRS)

    Modified rankin score(mRS)is used to evaluate the primary outcome. The scale of mRS is 0 to 6. The best neurological outcome is the mRS with 0, indicating no any symptom left, and a good neurological outcome is agreed with a mRS≤2. mRS of 6 is the worst, indicating death. mRS will be evaluated by outcomes assessor who is blinded to the grouping.

    post-procedural 90 days

Study Arms (2)

Local anesthesia/conscious sedation

OTHER

Patients will be injected by propofol (adjusted by bispectral index scale ≥70 ) and /or remifentanil(0.01-0.06μg/kg/min). Patients will maintain spontaneous breathing.

Procedure: Local anesthesia/concious sedationProcedure: Spontaneous breath

General anesthesia

OTHER

Patients will be induced with remifentanil (0.2-0.8 μg/kg), propofol (1-2mg/kg) and rocuronium (0.6 mg/kg). Anesthesia will then be maintained keep the BIS between 40 and 60 with propofol and remifentanil. After tracheal intubation, patients will be kept with controlled ventilation.

Procedure: General anesthesiaProcedure: Controlled ventilation

Interventions

Patients will be injected with propofol, remifentanil and muscular relaxant with controlled ventilation.

General anesthesia

Patients will be injected with propofol and remifentanil.

Local anesthesia/conscious sedation

Patients will be kept spontaneous breath.

Local anesthesia/conscious sedation

Patient will be kept with controlled ventilation.
