  Purpose

The overall goal of this study is to determine whether initiating hypothermia in cardiac arrest patients as soon as possible in the field results in a greater proportion of patients who survive to hospital discharge compared to standard prehospital/field care.

Primary Outcome Measures:
  • Survival and awake and able to follow commands at hospital discharge [ Time Frame: at hospital discharge ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • days to awakening, days to death, neurologic outcome [ Time Frame: at time of discharge, at 3 months following discharge ] [ Designated as safety issue: No ]

Enrollment: 1359
Study Start Date: December 2007
Study Completion Date: August 2013
Primary Completion Date: May 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
No Intervention: control treatment Other: Rapid infusion of 2 liters of 4oC normal saline
Patients randomized to mild hypothermia will receive a rapid infusion of 2 liters of 4oC normal saline prior to arrival in the emergency room. Patients randomized to control will receive standard of care following resuscitation from cardiac arrest.
Other Name: Rapid infusion of cold normal saline
Drug: Rapid infusion of cold normal saline

Detailed Description:

In this study we will randomize 1,200 cardiac arrest patients who have return of spontaneous circulation (ROSC) to hypothermia with rapid infusion of 2 liters of 4oC Normal Saline IV solution over 20 to 30 minutes, IV sedation and muscle paralysis or to standard of care following ROSC.

The primary objective of this study will be to determine whether induction of mild hypothermia using an infusion of cold normal saline will improve the proportion of patients who survive and are discharged awake from the hospital.

Hypothesis: In cardiac arrest patients who achieve ROSC in the field, initiation of hypothermia by infusion of cold normal saline will result in a greater proportion of cardiac arrest patients discharged awake from the hospital compared to standard care.
