Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Surgery - PARAMEDIC COOLING

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.


Treatment: Surgery: PARAMEDIC COOLING
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.

Summary
Brief summary
That paramedic core cooling during CPR using a rapid infusion of ice-cold (4 degrees C)
large-volume (30mL/kg) normal saline improves outcome at hospital discharge compared with
standard care in patients with out-of-hospital cardiac arrest.
