Arctic Sun Induced Hypothermia Following Cardiac Arrest
Therapeutic Hypothermia
- AHA Class I recommendation for comatose pts with out-of-hospital cardiac arrest, following ROSC and associated with Vfib (2005)
- Purpose: Decrease brain metabolism for reduced injury and improved outcomes
89.6° - 93.2°F (32° - 34°C), maintained 12-24hrs
Therapeutic Hypothermia
Effects of TH on Metabolism and Feeding Tolerance
Initial Assessment 1/01
- Consult received re: pt NPO on hypothermia protocol
ESTIMATED NUTRITION REQUIREMENTS
Kcal/day: 1462-1657 (18.7-21.2 kcal/kg)
Protein/day: 94 (1.2 gm/kg)
Needs based on: IBW, age, MI, arctic sun protocol (induced hypothermia)
- Decrease in REE ranging from ~75% to 85% of baseline
- Delayed gastric emptying / peristalsis
- Feeding = metabolism = temp
- Very limited research, no clear guidelines for feeding during TH
- Study results (2014): median 72% (~10ml/hr) of feeds tolerated during hypothermia; median 95% of feeds tolerated during warming period
- Sufficient GI function shown at core temperature of 33°C (mid-point of goal 32° - 34°C)
- YNHH Guidelines:
- Cooled or on paralytics = kcal by 15-25%, protein changes
- Shivering or rewarmed = kcal/protein changes
- Benefits of early feeding: maintain GI function, decrease infection risk, prevent bacterial translocation, avoid malnutrition, etc.
Assessment:
- OGT already in place
- Dopamine currently off
- Plans to feed once pt being rewarmed, per team
TYPES OF TH
- Invasive: Peripheral line or vascular catheter
- Non-Invasive: Low room temperature or surface coolants

PHASES OF TH
- Induction: Rapid cooling
- Maintenance: 12-24hrs @ goal temperature
- Re-warming: Active or passive ~14-16hrs
- Target rate of 0.32° - 0.33°F / hr
ESTIMATED NUTRITION REQUIREMENTS
Kcal/day: 1950 (25 kcal/kg)
Protein/day: 94 (1.2 gm/kg)
Needs based on: IBW, MI, arctic sun protocol (induced hypothermia now completed
Assessment:
- New low wt of 77.9kg (admit wt 88kg) 2/2 fluid overload s/p significant diuresis
- Feeds initiated 1/02 ~10am, stopped briefly @ 4pm for GRV 180ml --> goal rate reached on 1/07
- Re-warming started @ 5pm on 1/02 --> completed on 1/03
- Increased stooling 2/2 provision of goal nutrition following constipation
- Tolerating feeds well: 5ml GRV, soft abdomen, +BMs, - emesis
