Arms Assigned Interventions
No Intervention: Standard Treatment

For patients randomised to hospital cooling:

  • LMA/ Intubation and ventilation with 100% oxygen
  • Measure temperature using tympanic probe and record
  • Insert IV line and administer drugs as per protocol
  • Fluid challenge with standard temperature saline only as per current guideline (suspected hypovolemia)
  • Post resuscitation: midazolam 1-5 mg only to maintain LMA/ intubation as needed.
  • Pancuronium 8 mg only if intubation unable to be maintained with midazolam.

After arrival at the Emergency Department, all patients receive standard care.


For patients randomised to paramedic cooling:

  • LMA/ Intubation and ventilation with 100% oxygen
  • Measure temperature using tympanic probe and record
  • Paramedic cooling using infusion of 20mL/kg cold fluid via IV during CPR
  • If temperature >34.5ºC, infuse further 10mL/kg stat
  • After ROSC, infuse further (max 2 litres) ice-cold saline
  • If shivering occurs post resuscitation and intubated, administer midazolam 2-5mg IV and pancuronium 8 mg.
