NCT03229148

Brief Summary

Objective of the study: to assess whether pharmacological sedation or general anesthesia for treatment of anterior circulation ischemic stroke with endovascular mechanical thrombectomy is associated with difference in morbidity (neurological outcome and peri-procedural complications).

Outcome Measures

Primary Outcomes (1)

  • composite of functional independence at 3 months and absence of medical complication occurring by day 7 after endovascular therapy for anterior circulation AIS

    The primary outcome measure is a composite of functional independence at 3 months and absence of medical complication occurring by day 7 after endovascular therapy for anterior circulation AIS. Functional independence is defined as a mRS score 0 to 2 by day 90. Medical complications are defined as intervention-associated arterial perforation or dissection, pneumonia or myocardial infarction or acute cardiogenic pulmonary oedema or malignant stroke evolution occurring by day 7

    Day 90

Secondary Outcomes (19)

  • Ordinal score on the mRS by day 90

    at day 90

  • Functional independence by day 90 defined as a mRS score 0-2

    at day 90

  • Excellent recovery by day 90 defined as a mRS score 0-1

    at day 90

  • Moderate recovery by day 90 defined as a mRS score 0-3

    at day 90

  • Shift analysis of day 90 mRS adjusted for initial prognostic factors

    at day 90

  • +14 more secondary outcomes

Study Arms (2)

General anaesthesia

ACTIVE COMPARATOR

In the general anesthesia group, rapid sequence induction is used. Conduction of general anesthesia and drugs used are left to the expertise of each investigating center. Systolic blood pressure has to be maintained between 140 and 180 mmHg with an intravenous norepinephrine infusion if necessary, tele-expiratory carbon dioxyde concentration (EtCO2) has to be maintained between 30 and 35 mmHg and SpO2 has to be maintained between 94 and 98 %.

Procedure: General anaesthesia

Conscious Sedation

ACTIVE COMPARATOR

In the conscious sedation group, drugs choice as well as pharmacological modulation will be left to the expertise of each investigating center. A sedation level between 0 and -3 with spontaneous breathing will be targeted, using the Richmond Agitation Sedation Scale (RASS) score validated in French. The lightest sedation level will be targeted, i.e. minimal to moderate sedation according to the US recommendations for sedation / analgesia. Systolic blood pressure will be maintained between 140 and 180 mmHg with an intravenous norepinephrine infusion if necessary and SpO2 will be maintained between 94 and 98%.

Procedure: Conscious Sedation

Interventions

Procedure in which patients are induced into an unconscious state through use of various medications so that they do not feel pain during surgery

General anaesthesia

A drug-induced depression of consciousness during which patients respond purposefully to verbal commands, either alone or accompanied by light tactile stimulation. No interventions are required to maintain a patent airway. (From: American Society of Anesthesiologists Practice Guidelines)

Conscious Sedation

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Acute anterior circulation ischemic stroke (terminal portion of the internal carotid artery, middle cerebral artery), with indication for radiological mechanical thrombectomy assessed by the neurology / neuroradiology team
  • Over 18 years of age
  • Benefiting from an affiliation to the French Social Security system
  • Patient or familly informed consent. In case of patient incapacity and no family present, and due to the emergency of the procedure, the patient may be included on the sole decision of the investigator (emergency procedure with subsequent differed consent).

You may not qualify if:

  • Altered vigilance defined by score ≥ 2 at item 1a "level of consciousness" of the NIHSS score
  • Altered previous autonomy, defined by a modified Rankin score (mRS)\> 1
  • Acute ischemic stroke of posterior circulation or anterior cerebral artery
  • Associated brain haemorrhage
  • Pregnant or nursing women
  • Patient under law protection
  • Stroke complicating another acute illness or postoperative stroke.
