Hypothermia in Traumatic Brain Injury in Children (HiTBIC)

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT00282269

Brief Summary:

The purpose of this study is:

  • To determine the safety and feasibility of performing an international multi-centre randomized control trial of early and prolonged hypothermia to improve outcome in children with severe traumatic brain injury (TBI).
  • To determine whether in children with severe traumatic brain injury, prolonged initial hypothermia (minimum 72 hours at 32-33 degrees) improves the proportion of good outcomes 12 months after injury when compared to initial normothermia (36-37 degrees).

Condition or disease Intervention/treatment Phase
Traumatic Brain Injury Procedure: Induced Hypothermia Phase 2 Phase 3

Detailed Description:

We propose to do a pilot study of 50 children admitted with severe TBI to paediatric intensive care units in Australia and New Zealand. Severe TBI will be defined as children with either (i) Glasgow Coma Scale (GCS) ≤ 8 and an abnormal CT scan or (ii) motor score of ≤ 3 and normal CT scan. Children will be included only if they can be randomised within 6 hours of the injury occurring. Patients will be stratified a priori by (i) centre and (ii) Glasgow Coma Score. One half will be cooled to 32-33°C for 72 hours and then slowly rewarmed. If intracranial hypertension occurs during or after rewarming, the hypothermia group will have cooling continued until intracranial pressure (ICP) is controlled. The other half will have their temperature maintained at 36-37°C. All other aspects of care will be managed with a standardised protocol.

The purpose of this pilot study is to establish the feasibility of doing an outcome study with other international centres. It will also assess the safety of more prolonged cooling and protocol adherence. Primary outcomes will be the frequency of adverse events related to hypothermia, recruitment rates and protocol adherence. These children may also be able to be included in a larger trial.

The primary aim of the outcome study will be to determine whether, in children with severe TBI, prolonged initial hypothermia improves the proportion with good outcome 12 months after injury when compared to initial normothermia. Outcome will be assessed at 6 and 12 months. The primary outcome measure will be a Paediatric Cerebral Performance Category (PCPC) at 12 months after the date of injury, dichotomized to poor outcome (categories 4-6) and good outcome (categories 1-3). Secondary outcome measures will be (i) PCPC at 6 after injury (ii) standardised tests (intelligence and memory, functional outcome, attention, executive functions) 12 months after injury (iii) ICP and cerebral perfusion pressure (CPP) during the first 5 days of treatment (v) frequency and nature of interventions to control ICP/CPP (vi) duration of mechanical ventilation and (vii) potential adverse events.
