Purpose
Caffeinol is a combination of caffeine and alcohol. The amount given is about the same as 1-2 glasses of wine and 3-4 cups of coffee. The patient receives a one time dose given over two hour while being cooled to 34.5 C.

Primary Outcome Measures:
- Number of Participants With Symptomatic Intracerebral Hemorrhage [ Time Frame: from pre-dosage to 90 day followup ] [ Designated as safety issue: Yes ]Symptomatic intracerebral hemorrhages were measured by a full NIHSS(National Institute of Health Stroke Scale) prior to caffeinol & hypothermia,at the end of hypothermia & rewarming, 24 hrs after stroke onset, daily during hospitalization,& at the 90 day follow-up visit. In addition, modified NIHSS were done hourly during the 24 hr hypothermia period & 12 hr rewarming period. At the end of rewarming an MRI was obtained to verify if hemorrhages or neurologic deteriorations were present.NIHSS scores severity of stroke on 11 items;more points given for greater deficiencies(range 0-42,0=normal)
- Number of Participants With Catheter Related Complications During Hypothermia & Rewarming [ Time Frame: over 36 hour period ] [ Designated as safety issue: Yes ]Catheter-related complications assessed whether participants had bleeding (major hemorrhaging) that required a blood transfusion, this was determined by labs. Participants were monitored for infections every hour during vital signs in the 24 hour hypothermia phase and 12 hour rewarming phase.
- Number of Participants With Cardiorespiratory Failure [ Time Frame: every 30 minutes during hypothermia induction ] [ Designated as safety issue: Yes ]The possibility of cardiorespiratory failure was monitored every 30 minutes during the 24 hour hypothermia period based on vitals signs and oxygen saturation.
Secondary Outcome Measures:
- Feasibility: Time Required to Reach the Target Core Temperature or Lowest Tolerated Temperature, Stability of Patient Temperature, Control of Rewarming, [ Time Frame: rewarming over 12 hours until 36.5C has been achieved ] [ Designated as safety issue: No ]Hypothermia will be maintained for 24 hours, afterward, the patient will be rewarmed, gradually, over 12 hours to 36.5C.
- Achievement of Therapeutic Serum Ethanol and Caffeine Levels, and Amount of Sedation Needed to Suppress Shivering. [ Time Frame: rewarming over 12 hours until 36.5C has been achieved ] [ Designated as safety issue: Yes ]
- Efficacy: NIHSS < 2 at 24 Hours, Modified Rankin Scale (mRS) < 2 at 3 Months, NIHSS < 2 at 3 Months, and Length of Hospital and ICU Stay. [ Time Frame: 90 days ] [ Designated as safety issue: No ]NIHSS score of ≤ 2 24 hours after stroke onset modified Rankin Scale (mRS) < 2 at 90 day followup NIHSS score of ≤ 2 at daily duration of hospitalization and ICU stay and 90 day follow up.
