Hypothermia

The last part of the MARCH algorithm is Hypothermia.

Hypothermia is textbook defined as a core body temperature of 95 degrees F. That is not much lower than the average core body temp of 98.6 degrees F. In trauma blood loss and shock can lead to hypothermia. Remember, our blood helps us thermoregulate our body temperature. Burns is another big way we thermoregulate. Prevention is going to be key to hypothermia treatment. Hence why we put our casualties on a litter with at the very least a casualty blanket. By the time we get to this stage, it is recommended to figure out if they are in need of more aggressive hypothermia prevention. One thing that can help is if you add insulation to your hypothermia prevention. Whether that be a sleeping bag, or even just simply a woobie we want to add something that will help add to the heat retention (or r value for all your backpackers out there) of the hypothermia prevention. If we feel we need to add some sort of external heat source we can either add a ready heat, or simply add some large hand warmers to add more heat to keep their core temp up.

As we talked about in circulation, keeping them from going hypothermic will prevent them from entering the death spiral caused by the lethal triad. Hypothermia can prevent proper clotting and we want to encourage proper clotting, not prevent it. This is why you should bring your beanie even in the summertime. It might just help save your life.

Have you treated for hypothermia before? Have you ever gotten hypothermia before?

Come out to a class. We talk about this in WAY more detail and even will cover it in the final excercise.
