Take Home Points
  • Heat stroke is a life-threatening disorder characterized by elevated core temperature, compromise to neurologic function and multi-system organ dysfunction
  • The keystone of treatment is rapid cooling within 30 minutes of presentation preferably with ice water immersion
  • Patients with heat stroke should be investigated for rhabdomyolysis, AKI, liver failure and concomitant infection

Take Home Points:

  1. Hypothermia is neuroprotective and patients can survive prolonged periods of cardiac arrest. Termination of resuscitative efforts in cardiac arrest should not considered until the patient is >32°C or has a K > 12 mEq/L
  2. Active internal rewarming is the keystone of treatment for unstable hypothermic patients. Utilize available resources including ECMO to effectively warm your patient
  3. Consider alternate causes for hypothermia, especially in patients who fail to respond to warming

Definition:

  • Accidental hypothermia is an unintentional core body temperature of < 35°C when heat loss to surroundings is greater than heat generation
  • Most frequent cause is environmental exposure
  • Patient with impaired thermoregulation can develop hypothermia in relatively warm environments
    • Elderly, underlying illness, trauma, intoxication, or malnutrition (Brown 2012)

October 17, 2016

Definition: A life-threatening emergency in which there is a failure of the body’s thermoregulatory mechanisms to handle extrinsic and intrinsic heat. The failure of thermoregulation leads to multi-system organ dysfunction characterized by alteration of neurologic function. Unlike in fever, hyperthermia is not caused by endogenous pyrogens that change the thermoregulation set point in the brain. Hyperthermia results from excessive heat production and/or inadequate heat dissipation
