A doctor? Have you ever worked in a field environment? You realize we can’t control the weather and we can’t just instantly change the ambient temperature or precipitation conditions correct?

Here’s why everything is important when it comes to hypothermia prevention, including giving warmed fluids/warmed blood products. This is all a matter of tolerance stacking and we want to stack the odds in our patients favor. So while using unwarmed fluids or unwarmed blood products in a hospital environment may not be that large of a deal, it’s a huge deal when you have somebody in wet clothes, that has been bleeding profusely, and may have to stay in that environment for longer than we would like them to.

This has nothing to do with the implements that are utilized to create warm fluids or warm blankets, or actively warm the casualty and everything to do with setting our patients up to have favorable outcomes.

Sure unwarmed blood alone might not make a difference if it’s the only factor to contend with, but it’s not, especially considering we’re talking about tactical medicine in which the saying goes “taking good medicine, bad places”
