Hypothermia ICD-10

Hypothermia ICD-9

  •  780.65   Hypothermia not associated with low environmental temperature 
  • 991.6     Hypothermia: associated with low environmental temperature 
  • 995.89    Hypothermia due to anesthesia 
  • 778.2, 778.3  Hypothermia of newborn

Hypothermia Etiology / Epidemiology / Natural History

  •  30% mortality with severe hypothermia

Hypothermia Anatomy

Hypothermia Clinical Evaluation

  •  Cold +/- wet.  Depending on severity may be shivering, confused, or unconscious. 

Hypothermia Xray / Diagnositc Tests

  • Check vital signs.  Decreased pulse indicates moderate to severe hypothermia
  • Measure core temperature
  • Consider continuous oxygen saturation and EKG.

Hypothermia Classification / Treatment

  • Mild (Core temperature: 32°–35°C (89°–95°F): Confusion, shivering. Treatment: remove from the cold environment; wet clothing, removed.  Active warming using exogenous air-warming blankets.
  • Moderate (Core temperature: 28°–32°C (82°–89°F): Impaired judgment and apathy, shivering stops, muscle stiffness.  Treatment: remove from the cold environment; wet clothing, removed.  Active warming using exogenous air-warming blankets and active internal rewarming  with IV fluid warmed to 40°C to 43°C (do not use lactated Ringers-cold liver cannot metabolize lactate).
  • Severe (Core temperature: < 28°C (82°F): Loss of consciousness, decreased pulse, decreased respiratory rate, coma. Treatment: remove from the cold environment; wet clothing, removed.  Active warming using exogenous air-warming blankets and active internal rewarming  with IV fluid warmed to 40°C to 43°C (do not use lactated Ringers-cold liver cannot metabolize lactate).  Consider extracorporeal rewarming-peritoneal dialysis / chest tube irrigation.
