Hyperthermia & Heat-Related Illness

Get the lesson outline here: www.miglabs.com/hyperthermia
Summer is upon us and prehospital providers are likely to see more patients suffering from heat-related illness. The most serious heat-related illness - heat stroke - has a mortality rate of up to 30%, so it's important that we're prepared to treat hyperthermic patients.
This lesson will discuss heat stroke - the different types, how to diagnose it, and how to treat it, including some of evidence-based patient cooling strategies.

THANK GOD there is information dispelling the myth that heat stroke=no sweating or dehydration. This melarchy is still being taught in paramedic classes all over this country. Great video!

[@ceestudy5898]

whaat, my book also says that victims of heatstroke do not swear! what a mess

[@b.dwaynearmstrong577]

@@ceestudy5898 if you get to this point you are way behind the eight ball. The only 2 criteria that must be met is a core temp of 104f and altered mental status.

Thank you for all the information, I live in the middle east where it's very very hot and we r not very much educated on what's happening to our bodies during the summer. Thank and God bless you.

Regarding medications: Central nervous system dysfunction is a hallmark of heat stroke. Lack of neurological improvement with good basic medical management suggests the need to consider both brain injury and the deleterious effects of agitation and muscular activity such as tremulousness and shivering. Heat stroke patients can seize due to brain injury, electrolyte imbalance, or a combination of the two. Benzodiazepines are the drug of choice in this situation because they have a beneficial effect on the agitation and may lower the risk of a seizure. So remember- immediate administration of benzodiazepines is indicated in patients with agitation and shivering, to stop excessive production of heat. (This was a Board exam question for Pediatric Emergency Medicine)

Great job with this video!

I don't know if it's a myth... But I can say first hand that I was not sweating like my body normally should have been. I felt it. So even if it is a myth. It sounds like a very "plausible" myth. I suffered this Heat Stroke just today

[@ceestudy5898]

thank you so much!! Very well explained!

[@blackhillsoutdoorsman5487]

This video was wonderful. Very informative and helpful! Thanks a lot.

[@explorenuevaecija]

I agree.😊 It’s very informative.

Crap. I was probably on the verge of heatstroke yesterday. The thing that scared me was that I had problems recalling my students' names and ages and the words to the birthday song- all things I know on any other given day. Also, I was so very red and sweating so much my eyelids were wet. I never sweat like that at work.

Heat exhaustion is more common than heat stroke.

All of the colors except red are ok to use.

Many people have normal temperatures that run a little lower or higher normally. If a person has not reached 104 degrees Fahrenheit but has an elevated temperature to 102 or 103 and has changes in CNS functioning, could you still have a "field impression" of heat stroke?

[@Miglabs]

Absolutely. These numbers (and really, just about any numbers in medicine) are based on averages. There are always going to be outliers who fall outside the averages, so if all signs point toward heat stroke in a patient with a temperature of, say, 103 °F, it would probably be wise to still consider heat stroke.

Am 56, good shape, moved to Tuscon in April. Being very physical, I continued as usual until I was feeling cold in 95 degree temp. Thought it was strange, but nothing more. While washing car I got weak, then a headache behind eyes. Went inside at around 4pm, ended up staying in bed until around 3pm the next day. Headache cleared, was able to drink and eat again. Was this heat related? Or simply age? I did feel cool and didn't sweat, but was full of liquid and urinating well. Do I need to reduce activity? Yes, it's kind of obvious, but really! I wasn't running or doing much, just was 95 out in dry Tuscon climate.. thanks... Also during down time in bed, I was shifting from cold to warm by the minute. Was putting covers over body, then opened widow for air. Indoors was 75 degrees. Thanks

Why no cool water immersion for classic heat stroke patients?

[@Miglabs]

Hi Michael, Great question! I answered it on the MIG Labs lesson page, including references to some other studies and publications: miglabs.com/hyperthermia#comment-7 Basically, it boils down to this: exertional heat stroke patients tend to be young, healthy, athletic people, and they can tolerate the stresses of rapid core cooling. Classic heat stroke patients, however, tend to be a different population, and studies have shown that morbidity and mortality increases when they are subjected to cool or ice water immersion.

[@mra1385]

Awesome, thank you! I love your channel and your website by the way. Keep up the great work.
