Induction of hypothermia to < 35˚C by < 2.5 hours after severe traumatic brain injury, reaching 33˚C by 4 hours after injury and maintained for 48 hours in patients aged 16-45 will result in an increased number of patients with good outcomes at six months after injury compared to patients randomized to normothermia.

Primary Outcome Measures:
  • The Dichotomized Glasgow Outcome Scale [ Time Frame: 6 months with a window of plus or minus one month ] [ Designated as safety issue: No ]
    The primary outcome measure was the Glasgow Outcome Scale measured in person six months after injury by examiners who were blinded to the patient's treatment group. Good recovery and moderate disability were designated as favorable outcomes; severe disability, a vegetative state, and death as poor outcomes.

Other Outcome Measures:
  • Glasgow Outcome Scale - Extended [ Time Frame: 0-12 months ] [ Designated as safety issue: No ]
  • Disability Rating Scale [ Time Frame: assessed 0-12 months ] [ Designated as safety issue: No ]
  • Neurobehavioral Rating Scale - Revised [ Time Frame: 0-12 months ] [ Designated as safety issue: No ]
  • Neurological Outcome Scale for Traumatic Brain Injury [ Time Frame: 0-12 months ] [ Designated as safety issue: No ]
  • Symbol Digit Modalities Test [ Time Frame: 0-12 months ] [ Designated as safety issue: No ]
  • Rey Osterrieth Complex Figure [ Time Frame: 0-12 months ] [ Designated as safety issue: No ]
  • Verbal Selective Reminding Test Trails B [ Time Frame: 0-12 months ] [ Designated as safety issue: No ]
  • Grooved Pegboard [ Time Frame: 0-12 months ] [ Designated as safety issue: No ]
  • Controlled Oral Word Association Test [ Time Frame: 0-12 months ] [ Designated as safety issue: No ]

Arms Assigned Interventions
Active Comparator: hypothermia
Induction and maintenance of moderate hypothermia to 33 degrees celsius achieved within 2.5 hours of injury and maintained for 48 hours.
Device: Hypothermia
Induction of moderate hypothermia to 33 degrees celsius, within 2.5 hours from time of injury and maintained for 48 hours
Other Name: moderate hypothermia
No Intervention: control
treated at normothermia

Detailed Description:
NABIS:HIIR was a randomized clinical trial conducted in patients with severe brain injury, age 16-45. Patients were randomized to standard treatment at normothermia or to standard treatment with moderate hypothermia (32.5-34C for 48 hours). An intent to treat analysis was used with the primary outcome measure as the Glasgow Outcome Scale at six months after injury. GOS is dichotomized into good outcome (Good Recovery/Moderate Disability) and poor outcome (Severe Disability, Vegetative, Dead).
