hypothermia

Question 1

moderate hypothermia

Answer 1

28-32 C or 82-90F

bradycardia, lethargy, hypoventilation, decreased shivering and atrial arrhythmias

Question 2

mild hypothermia

Answer 2

32-35 C or 90-95F

tachycardia, tachypnea
ataxia, dysarthria, increased shivering

Question 3

severe hypothermia

Answer 3

<28 C (82F)

coma, cardiovascular collapse, ventricular arrhythmias

Question 4

Treatment of hypothermia in general

Answer 4

warm 42C (107F) crystalloid for hypotension

endotrachial intubation for people who are comatose

Rewarming techniques are based on severity of hypothermia

Question 5

Mild hypothermia treatment:

Answer 5

passive external warming (remove wet clothing and cover with blankets)

Question 6

moderate hypothermia treatment

Answer 6

active external warming (warm blankets, heating pads, warm baths)

Question 7

severe hypothermia treatment

Answer 7

active internal rewarming (warmed pleural or peritoneal irrigation, warmed humidified oxygen)

Question 8

why is there sometimes an initial drop in core temperature after starting IV warmed fluids for pts who have hypothermia?

Answer 8

because of return of cold blood from cold extremities.

Question 9

if severe hypothermia for moderate hypothermia that doesn’t respond to initial measures what to do next?

Answer 9

warm pleural or peritoneal irrigation, cardiopulmonary bypass or venoartierial extracorporeal membrane oxygenation.

This can rewarm faster.

Question 10

treatment of cardiac arrhythmia associated with hypothermia

Answer 10

cardiac arrhythmias like afib will spontaneously convert and correct with rewarming.
