COOL-ARREST Pilot Study to Assess Intravascular Temperature Management (IVTM) in the Treatment of Cardiac Arrest (COOL-ARREST)

This study has been completed.
Information provided by (Responsible Party):
ZOLL Circulation, Inc., USA Identifier:
First received: February 4, 2013
Last updated: April 25, 2016
Last verified: April 2016
A multicenter prospective single arm interventional trial in hospitals where therapeutic hypothermia is standard practice. This trial will enroll 50 subjects to evaluate the ability of the ZOLL Intravascular Temperature Management (IVTM) System to induce, maintain, and reverse mild therapeutic hypothermia and maintain normothermia post cardiac arrest.

Condition Intervention
Out of Hospital Cardiac Arrest Device: ZOLL Intravascular Temperature Management System (IVTM)

Study Type: Observational
Study Design: Observational Model: Case-Only
Time Perspective: Prospective
Official Title: A Multicenter, Prospective, Single Arm Observational Trial to Assess Intravascular Temperature Management (IVTM) in the Treatment of Cardiac Arrest

Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Sampling Method:   Probability Sample
Study Population
Subjects that have experienced an out-of-hospital cardiac arrest.

Inclusion criteria:

  1. Signed informed consent
  2. 18 years of age or older
  3. Out-of-hospital witnessed cardiac arrest with any rhythm [Ventricular Fibrillation/Tachycardia (VF/VT), Pulseless Electrical Activity (PEA), or Asystole (AS)] during EMS phase of treatment


    Out-of-hospital unwitnessed cardiac arrest with VF upon EMS arrival

  4. Lack of meaningful response to verbal commands upon arrival to hospital after suffering non-traumatic cardiac arrest in an out-of-hospital setting
  5. Return of spontaneous circulation (ROSC) within 30 minutes of EMS arrival
  6. Able to maintain a SBP > 90mmHg for 30 minutes post ROSC without the use of pressors OR with stable dose of pressors (if escalation of pressors is required, patient is not eligible)
  7. Undergoing Therapeutic Hypothermia using ZOLL's IVTM System within twelve hours of ROSC BUT should have been initiated as soon as possible

Exclusion Criteria

  1. Traumatic cardiac arrest [due to blunt trauma, penetrating injury (e.g., stabbing, gunshot, etc.), burns, exsanguinations, strangulation, smoke inhalation, electrocution, hanging, drowning, etc.]
  2. Toxicological etiology (e.g., inhalation of toxic substances, drugs, etc.)
  3. Known or suspected pregnancy
  4. Do Not Attempt to Resuscitate (DNAR) order in force
  5. Ward of the state or prisoner
  6. Anatomy, previous surgery or disease state contraindicating femoral venous access
  7. Received neuromuscular blocking agents or central nervous system sedatives whose effects have not worn off prior to assessing level of consciousness following ROSC
  8. Hypothermia initiated at a transferring facility prior to arrival at the enrolling hospital (excludes pre-hospital IV fluids or cold packs for cooling by EMS)
  9. Current Inferior Vena Cava (IVC) filter
  10. Known history of acute neurological illness or severe functional disabilities prior to arrest (e.g., seizures, traumatic brain injury, increased intracranial pressures, intracerebral hemorrhage, etc.)
  11. Known heparin allergy
  12. Known allergy to any adjunctive pharmacologic agent required for induction or maintenance of therapeutic hypothermia
  13. Known history of bleeding or blood disorders such as coagulopathy, cryoglobulinemia, sickle cell or thrombocytopenia with a platelet count below 40,000.
  14. Known hypersensitivity to hypothermia including a history of Raynaud's disease
  15. Evidence of intracranial bleed
  16. Terminal illness or life expectancy of less than 3 months prior to arrest
  17. Currently enrolled in another investigational drug or device trial that has not completed the primary endpoint or that clinically interferes with this trial's endpoints Note: For the purpose of this protocol, subjects involved in extended follow-up trials for products that were investigational but are currently commercially available are not considered enrolled in an investigational trial.
