Brief Summary:

Ischemia-reperfusion leads to mitochondrial injury, ion-pump injury, cell membrane damage, cytotoxic edema, and excessive oxygen free radical formation, and eventually destroys cells. Cardiac arrest is an example of global ischemia; after spontaneous circulation is restored, ischemia-reperfusion injury develops in cardiac arrest survivors.

Remote ischemic postconditioning (RIPoC) involves the application of brief, reversible episodes of ischemia and reperfusion to a vascular bed or tissue, rendering remote tissues and organs resistant to ischemia-reperfusion injury. Accordingly, RIPoC has been suggested as adjunctive therapy to mitigate ischemia-reperfusion injury. RIPoC applied by repeated brief inflation-deflation of a blood pressure cuff protects against myocardial injury, and has been proven effective in acute myocardial infarction.

This study aims to perform a randomized controlled trial to determine whether RIPoC has a neuroprotective effect and aids in myocardial recovery in out-of-hospital cardiac arrest patients after restoration of spontaneous circulation.

Neuron-specific enolase (NSE) at 48 hours after restoration of spontaneous circulation will be measured as a primary outcome.

Arm Intervention/treatment
Experimental: Remote Ischemic post-conditioning Procedure: Remote ischemic post-conditioning
Remote ischemic post-conditioning will undergo in both thighs at the beginning of targeted temperature management. This will be done with noninvasive measurement of blood pressure, with cuffs inflated to 200 mmHg for four 5 min cycles and interrupted three times for 5 min with cuff deflation.

No Intervention: standard of care

Primary Outcome Measures :
  1. neuron specific enolase [ Time Frame: at 48 hour after restoration of spontaneous circulation ]
    expressed in ng/ml

Secondary Outcome Measures :
  1. change over troponin-I [ Time Frame: at 24 hour and 48 hour after restoration of spontaneous circulation ]
    troponin-I will be expressed in ng/ml

  2. change over creatinin kinase-MB [ Time Frame: at 24 hour and 48 hour after restoration of spontaneous circulation ]
    CK-MB will be expressed in ng/ml

  3. neurologic outcome [ Time Frame: an average of 3 weeks after restoration of spontaneous circulation ]
    cerebral performance category scale 1, 2, 3, 4, 5

Other Outcome Measures:
  1. microRNA [ Time Frame: at 48 hour after restoration of spontaneous circulation ]
    only in patients with shockable rhythm

  2. neurologic outcome [ Time Frame: six month after cardiac arrest ]
    cerebral performance category scale 1, 2, 3, 4, 5
