Cooling Post-Cardiac Arrest in Ontario
Overview: Pre-Hospital Cooling and the ICE-PACS trial
Practical Issues: Randomization, Eligibility, How to Cool, Equipment
and Storage
Frequently Asked Questions
ICE-PACS
SPARC Network: 36 hospital across Southern Ontario
A 2-year comprehensive educational program to increase application of in-hospital cooling to cardiac arrest survivors
Even after this large and expensive project, cooling was still only attempted in about half of eligible patients and often with great delays (less than 1/3 cooled within 6 hours). It's time to start thinking about cooling eligible patients as soon as possible, similar to how we currently triage STEMI patients to obtain prompt diagnosis and treatment."
Cooling after cardiac arrest saves lives…How is Ontario Doing?
ICE-PACS
The ICE-PACS Trial:Initiation of Cooling by Emergency medical services to Promote the Adoption of timely therapeutic hypothermia in Cardiac arrest Survivors
RCT comparing pre-hospital initiation of cooling by EMS providers versus usual post-resuscitation care
GOAL: to increase the number cardiac arrest survivors that are successfully cooled to target temperatures (32 to 34 degrees) within 6 hours of hospital arrival by starting the cooling process sooner
Overall goal is to improve clinical outcomes for cardiac arrest survivors
ICE-PACS
How Can ICE-PACS Help Our Patients?
ICE-PACS seeks to change the way we think about treating cardiac arrest survivors
Shift focus from “where” treatments can be provided (i.e. In or out of hospital) to “when” treatments are provided.
Analogy: Paramedics already save thousands of lives each year by recognizing STEMI early to prevent delays in diagnosis and hasten access to treatment. ICE-PACS tests whether this kind of earlier recognition and treatment with cooling can also prevent delays and save lives
ICE-PACS
Theoretical Risks – Common Questions Cooling is generally safe and well tolerated The more frequent side effects:
shivering peripheral vasoconstriction sinus bradycardia cold diuresis electrolyte disturbances
No increased incidences of serious clinical adverse events have been documented in any of the existing small pre-hospital cooling studies (Kämäräinen et al, systematic review 2009)

ICE-PACS
Midazolam Midazolam is given to prevent shivering during induction of
cooling
Midazolam should be given to all patients that are randomized to cooling
SBP must be ≥ 100 (can be stabilized with dopamine and/or fluids)
Can give 5 mg IV bolus, followed by another 2.5 to 5 mg IV bolus after 5 minutes (max. total dose 10mg)
ICE-PACS
Clinical Considerations 1st IV – dedicated line for ALS medications
Ideally 2nd IV (preferably saline lock) for cold saline, run through COLD tubing kept in cooler
Ideally target left arm for both IVs (if possible)
ONLY If a 2nd IV cannot be established AND patient NOT requiring dopamine, can use 1st IV to infuse cold saline and usual (room temperature) tubing
ICE-PACS
Clinical Considerations Dopamine requires a dedicated IV line
If only 1 IV can be established and patient needing dopamine, then dopamine takes precedence over cold saline until a second line can be established. (frozen gel packs can still be used for surface cooling if patient is randomized for cooling)
The application of therapeutic hypothermia should not detract from rapid transport, optimizing ventilation and oxygenation, or the management of a re-arrest
REMEMBER TO USE THE POST-ROSC CHECKLIST!
ICE-PACS
Clinical Considerations In the event of a re-arrest:
Discontinue cold saline
If SBP < 90 mmHg
DESPITE dopamine and fluids, discontinue cold saline until SBP ≥ 90 mmHg
Can continue cold saline as long as SBP > 90 mmHg
In both situations:
Can continue surface cooling
Leave wrist band and ankle band in place!

ICE-PACS
Q: Why will the IV tubing kept in the cooler?
A: The IV tubing will be kept in the cooler to keep it cold. Considerable heat loss can occur when the IV tubing is at room temperature, due to the exposure created by the large surface area of the tubing.
Q: Why are we using a wrist band AND an ankle band when patients are cooled?
A: These are intended to help remind in-hospital clinicians to cool. The wrist band should be easily visible to all and the ankle band is for cardiologists performing PCI (who might not look beyond the femoral artery)
Q: Can the cooling contribute to an arrhythmia or increase pulmonary edema in our patients?
A: The most common arrhythmia is sinus bradycardia, which usually doesn’t require any treatment. More worrisome arrhythmias are not usually seen in the temperature range targeted by therapeutic hypothermia (32 to 34°C), unlike severe hypothermia due to exposure (i.e. <30°C). There does not appear to be any increase in pulmonary edema due to the cold saline.
FAQs and Answers
ICE-PACS
FAQs and AnswersQ: How quickly does the temperature change when cooling is initiated?
A: Based on the Bernard Trial, the average temperature drop was about 1.5°C during transport to hospital
Q: What are the next steps for EMS after the patient is cooled?
A: Complete the patient chart insert, ensure to record all data requested on the ePCR, and provide patient insert to attending hospital staff
Q: What will happen to cooled patients that we leave at the hospital?
A: In-hospital clinicians will usually use the exact same strategies to continue hypothermia for 12 to 24 hours. These typically include surface cooling (ice-packs), more cold saline, and deep sedation. Occasionally neuromuscular blockers will be needed to stop shivering. Some centers have specialized cooling devices that will be used to help speed up the cooling process.
Q: If we know cooling works, is it ethical to not simply cool all patients?
A: We know cooling works when applied in hospital. The existing evidence shows pre-hospital cooling is likely to be safe, but the trials were small. If pre-hospital cooling in ICE-PACS doesn't improve outcomes, or is associated with harm, then it will help prevent widespread implementation, and allow medics to focus on other pre-hospital interventions that are proven to be helpful.
ICE-PACS
FAQs and AnswersQ: Do we have to lug the cooler onto every CA call? We already carry so much!A: This is a good point, and we agree! Remember, you can simply leave the cooler in the ambulance! All that is needed initially is the ICE-PACS randomization envelope in your medic bag. If the patient meets the inclusion criteria and has no exclusions, open the envelope. If the patient is randomized to cooling, then instead of lugging the cooler to the scene, cooling can start in the ambulance en route to the hospital. Once in the ambulance, please remember to place the wristbands on the patient, add the cold gel-packs and run a line for the chilled-saline. All randomized patients – including those randomized to “no-cooling” – need to have their randomization number recorded on the ePCR and will have a patient chart insert in the envelope that should be provided to the ED staff.Q: Is the main goal of the study remind the ED staff to cool in-hospital, or to “do the work that doctors and nurses should be doing”?A: This is FALSE! The goal of this study is to see if starting cooling sooner will help more patients to reach the target temperature of 32-34 degrees within 6 hours, and whether this in turn can help more patients achieve improved outcomes. This study hopes to change the way we think about treating cardiac arrest survivors. Rather than focusing on “where” treatments can be provided (for example, in the field versus in the hospital), we believe paramedics can play a vital role in improving “when” treatments are provided. We know that paramedics already save many lives each year by recognizing STEMI early to prevent delays in diagnosis and hasten access to treatment. In the same way, this study tests whether earlier recognition and treatment with cooling after cardiac arrest by paramedics can also prevent delays and save lives.

FAQs and Answers
Q: Do Rescu researchers receive incentives or rewards for participating in ICE-PACS?A: None of the physicians or researchers involved in this trial receives any incentives for their work on this study. The main benefit for doctors running these trials (such as Dr. Laurie Morrison and Dr. Damon Scales) is their academic recognition in the medical society, and the satisfaction of working with paramedics to improve the healthcare system. Although incentives have previously been provided to paramedics for participating in trials, we now know that this is considered unethical because it creates the potential for a conflict of interest and could unintentionally lead to more ineligible patients being enrolled. This is especially important because cardiac arrest survivors are usually unconscious and incapable and so can’t make decisions about participating in research (the research is conducted using a waiver of informed consent). The ICE-PACS study is funded by the Canadian Institutes for Health Research and not by a pharmaceutical company, which means that there are no financial conflicts of interest but also that there is a very tightly-controlled and limited budget!
