About this trial

This is an interventional treatment trial for Traumatic Brain Injury focused on measuring Traumatic, Brain, Injury

Eligibility Criteria

18 Years - undefined (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  1. Adult males or females ≥ 18 years of age
  2. Subjects with Traumatic Brain Injury and a post-resuscitation Glasgow Coma Score (GCS) ≤ 8
  3. In-hospital and screened within 7 hours of injury.
  4. Able to obtain legally effective written consent from authorized representative
  5. Patients who are intubated and on mechanical ventilation
  6. Admitted to ICU

Exclusion Criteria:

  1. Bladder or rectal core temperature below 32C (89.6F) upon admission
  2. Clinical brain death
  3. Patients with open abdomens.
  4. Multiple orthopedic injuries (> 2 long bone fractures)
  5. Persistent hypotension (systolic blood pressure < 90mmHg)
  6. Persistent hypoxia (O2 Saturation < 94%)
  7. Persistent metabolic acidosis (Lactic acid > 5 mmol/L, arterial pH < 7.25)
  8. Positive serum pregnancy test
  9. Cardiac arrhythmia with deleterious hemodynamic effects; heart block or myocardial damage (as shown on ECG)
  10. History of abnormal renal function
  11. Significant Co-morbidity (i.e. CAD;COPD; severe coagulopathy)

Outcomes

Primary Outcome Measures

GOS (Glasgow Outcome Score)
GOS=5 (Good Recovery) - Capacity to resume normal occupational and social activities, although some there may be some minor physical or mental deficits or symptoms. GOS=4 (Moderate Disability) - Independent and can resume almost all activities of daily living. GOS=3 (Severe Disability) - No longer capable of engaging in most previous personal, social or work activities. Typically are partially or totally dependent on assistance from others in daily living. GOS=2 ( Persistent Vegetative State ) GOS=1 (Dead)

Secondary Outcome Measures

GOS
GOS score
Vasospasm
as measured by TCD (Transcranial Doppler)

5. Study Description

Brief Summary
The investigators hypothesize that hypothermia (body cooling) and additional magnesium sulfate will improve the outcome of severe Traumatic Brain Injury (TBI) patients. This is a study to compare the outcomes of patients with severe traumatic brain injury who have been allocated to one of the following three groups: Group 1 - Conventional therapy following traumatic brain injury Group 2 - Subjects will have their core body temperature lowered to 34C Group 3 - Subjects will have their core body temperature lowered to 34C and will receive a supplemental intravenous infusion of magnesium sulfate.
