hypothermia Flashcards
1
Q
what do we see in ECG if we suspect hypothermia
A
J wave formation
2
Q
criteria for hypothermia and severe
A
hypothermia less than 35 degrees
severe hypothermia less than 32 degrees
3
Q
Immediate treatment of hypothermia
A
slow rewarming - active external earming, warm blankets, warm room, and hot drinks may suffice. Thermal blankets
high urea - IV fluid replacements
- cathether - monitor fluid balance
4
Q
why is slow rewarming done in elderly
A
too rapid rewarming may cause vasodilatation leading to shock leading to death
5
Q
Recommended rate of rewarming
A
0.5-2 degrees per hour
6
Q
Treatment for severe hypothermia
A
less than 30 degrees -warming can be achieved in suitable patients using peritoneal or heamodialysis or cardiopulmonary bypass
7
Q
complications of hypothermia
A
pneumonia renal failure arryhthmia myocardial infarction DIC
