What is less than 35 C
temperature that defines hypothermia
|
Osborn wave
feature seen on electrocardiogram with temp below 32 seen at the junction of the QRS
|
frostbite
most common freezing injury
|
nifedipine
treatment for refractory pernio
|
60-90 days "frostbite in january, amputate in july"
how long does it take for tissue to demarcate after frostbite?
|
32 C
the temperature at which shivering stops
|
Afib
common arrhythmia with temps below 32C
|
prefreeze
the phase of cold injury where cutaneous sensation is lost
|
iv penicillin for strep prophy
severe cases of frostbite should be treated with what antibiotic for prophylaxis?
|
cold induced vasodilation. in 5-10 minute cycles in temps below 10c the body will vasodilate to protect the extremity from prolonged vasoconstriction
what is the hunting response?
|
25 C
cerebral autoregulation is maintained with an increase in vascular resistance until what temp?
|
atropine
bradydysrhythmias in hypothermia are refractory to a common code drug. name it.
|
frostnip
superficial injury that presents with numbness and tingling that resolves after rewarming
|
solumedrol/hydrocortisone for presumptive adrenal insufficiency, and/or thyroxine for potential myxedema
a patient presents comatose, hypothermic. treated and fails to rewarm. what meds should be given?
|
eskimo or lapp/nordic
people of this ethnic descent are capable of stronger cold-induced vasodilation than average
|
32 C
temperature at which myocardium becomes irritable
|
bretylium
name the drug effective for chemically defib in hypothermia(no longer regularly available)
|
chilblains(pernio)
cold sores that affect exposed areas after 24 hours, usually with repetitive exposure
|
FALSE. tissue refreezing is disastrous, and it is preferable to ambulate to safety of frozen extremities if rescue will be delayed
true or false:rewarming should be initiated in the field regardless of whether there is a chance of refreezing
|
paradoxical undressing
name the clinical situation in which patients remove clothing in response to a cold stress
|
28-30 C
defibrillation is rarely successful below what temp
|
rewarm to 28-30 before reattempting defib, continue cpr
pt is in vfib with temp of 22F. defib is unsuccessful. what do you do?
|
trenchfoot
nonfreezing injury produced by prolonged exposure to wet cold at temperatures above freezing, commonly seen in people wearing neoprene socks
|
common in septicemia, broad spectrum abx
may also see in shaken baby
baby presents at 3 days of life with hypothermia. they are lethargic with a weak cry and rosy cheeks. workup/treatment?
|
False! tissue decomp, apparent rigor, dependent lividity, and fixed dilated pupils ARE NOT RELIABLE CRITERIA for withholding cpr in a hypothermic pt
true or false: a patient presents cold, stiff, cyanotic with fixed pupils and inaudible heart tones. pt should be pronounced.
