  Purpose

The objective of the COOLCATH study is to compare the effect of the RhinoChill transnasal cooling system to current standard Blanketrol III cooling blanket in its ability to achieve therapeutic hypothermia (TH) induction for patients undergoing TH after cardiac arrest.

The COOLCATH study will be a prospective, open-label randomized controlled trial comparing induction of TH efficacy and outcomes of patients following cardiac arrest. Any patient with return of spontaneous circulation (ROSC) following a cardiac arrest within the Essex Cardiothoracic Centre (CTC), or who is brought to the Essex CTC and is a candidate for TH will be considered for this study.

Arms Assigned Interventions
Active Comparator: Arm A - Blanketroll lll
Cutaneous Cooling Blanket, Blanketroll lll, applied to cool patient to 32C. Standard care
Device: Induced Therapeutic Hypothermia
Head to head, direct comparator of two standard care devices/treatments (RhinoChill versus Blanketroll lll) to assess time to induced therapeutic hypothermia
Other Name: RhinoChill will be compared with Blanketroll lll
Active Comparator: Arm B - RhinoChill
Intra nasal cooling system, RhinoChill, to cool patient to 32C - Standard care
Device: Induced Therapeutic Hypothermia
Head to head, direct comparator of two standard care devices/treatments (RhinoChill versus Blanketroll lll) to assess time to induced therapeutic hypothermia
Other Name: RhinoChill will be compared with Blanketroll lll

Detailed Description:

According to standard practice patients will be fully anaesthetised, intubated and ventilated. Patients will have a baseline tympanic temperature measurement taken and then will be randomized to receive induction of TH by either RhinoChill Transnasal cooling system, or standard care using the Blanketrol III cooling blanket.

All patients will have tympanic and oesophageal temperature measurement every 10 minutes until they reach TH (<34 degrees centigrade). Once TH is achieved, the RhinoChill will be discontinued, and all patients will then receive the Blanketrol III cooling blanket for maintenance of TH for the standard 24 hour period. If a patient achieves a core body temp of 34 degrees centigrade while undergoing RhinoChill cooling and is still on the cath lab table, the device will be turned to low flow to ensure that the temperature is maintained until a transfer to the Blanketrol system is possible. For patients that arrive in the ICU on RhinoChill with a temperature >34 (i.e. have not reached TH), these patients will have RhinoChill and blanket therapy until they reach <34 degrees centigrade when the RhinoChill will be discontinued.
