Values are expressed as mean ± standard deviation. aGood outcome corresponded to CPC scores of 1 or 2; poor outcome corresponded to CPC scores of 3 to 5. ACLS, advanced cardiac life support; CA, cardiac arrest; MIH, mild induced hypothermia; ROSC, return of spontaneous circulation; SAPS, Simplified Acute Physiology Score. | ||||
