Environment

Question 1

1. What are the temps for Mild, Moderate and Severe hypothermia?

Answer 1

• Mild 32-35
• Moderate 28-32
• Severe <28

Question 2

2. What needs to be considered in regards to Cardiac arrhythmias and Hypothermia?

Answer 2

• Associated with temps <33

- Defibrillation and cardioactive meds may not be effective at temp <30, VF may resolve upon rewarming

Question 3

3. What is the ideal positioning for Hyperthermia?

Answer 3

Flat or lateral and avoid head-up to avoid hypotension, collapse and possible arrhythmias. Gentle handling is essential.

Question 4

4. What is the target temp for Hyperthermia?

Answer 4

<40 within 30mins of onset of symptoms

Question 5

5. What are the key S/S of Hyperthermia?

Answer 5

• ACS, confusion, incoherent speech
• Dizziness/collapse
• N/V
• Abnormal gait
• Seizures

Question 6

6. What is the Rx for Environmental/Exertional Hyperthermia?

Answer 6

• Cooling techniques
• Elderly/frail: Cold NS IV (Max 20mL/kg) - Reassess after each 500mL increment
• Young/fit/healthy: Consider immediate ice bath or cold shower, cooling techniques, Cold NS IV max 40mL/kg

Question 7

7. What is the Rx for Toxin induced Hyperthermia?

Answer 7

• Consider early MICA request
• Cooling techniques
• Early Tx
• Cold NS 20mL/kg (max 40mL/kg)
• Rx agitation early to facilitate cooling
