Hyperthermia

Remove patient to cool area
If patient temperature >104F or >40C or if altered mental status, begin active cooling
IV fluids 0.9% NaCl to maintain SBP ≥90 mm Hg or >minimum for age and signs of adequate perfusion
If uncontrolled shivering occurs during cooling—ADULTS ONLY, lorazepam 0.5-1.0 mg IV/IM or diazepam 2 mg IV or 5 mg deep IM

Hypothermia

Handle carefully and prevent further heat loss
If patient is alert enough to swallow, give food and drinks high in calories
Oxygen, heated and humidified if possible
IV fluids to maintain SBP >90 or minimum for age and signs of adequate perfusion
For patients with altered level of consciousness, consider Narcan or D50W when appropriate
No medications if core temperature is <86F or <30C
