Outcome Measures

Primary Outcomes (1)

  • Dynamic cerebral autoregulation parameter

    Dynamic cerebral auto-regulation parameters derived from transfer function analysis. Continuous cerebral blood flow velocities of bilateral middle cerebral artery will be assessed noninvasively using transcranial Doppler. Spontaneous arterial blood pressure will be simultaneously recorded using a servo-controlled plethysmograph on the left or right middle finger with an appropriate finger cuff size. Transfer function analysis will be used to derive the autoregulatory parameters.

    0-7 days

Secondary Outcomes (2)

  • National Institute of Health stroke scale (NIHSS)

    0-7 days

  • modified Rankin Scale (mRS)

    0-90 days

Study Arms (2)

RIC+Standard medical treatment

ACTIVE COMPARATOR

RIC+Standard medical treatment. Remote ischemic conditioning (RIC) is induced by 4 cycles of 5 min of healthy upper limb ischemia followed by 5 min reperfusion. Limb ischemia was induced by inflation of a blood pressure cuff to 200 mm Hg. RIC will be conducted twice daily for 7 consecutive days from thrombolysis.

Procedure: Remote ischemic conditioningOther: Standard medical treatment

PLACEBO COMPARATOR

Sham RIC+Standard medical treatment. Remote ischemic conditioning (RIC) is induced by 4 cycles of 5 min of healthy upper limb ischemia followed by 5 min reperfusion. Limb ischemia was induced by inflation of a blood pressure cuff to 60 mm Hg. RIC will be conducted twice daily for 7 consecutive days from thrombolysis.
