Just my initial thoughts, as a ground and flight medic now not an 18 anymore, is that I would take the helmet off ASAP for airway control, C-spine control, and good assessments. I am not really concerned as a first responder about brain cooling. I have heard about the benefits later on in the ICU.
We are also starting to get on board with prehospital hypothermic care for cardiac resuscitation, but are not there yet. Also that is all over the body not just isolated to the head.
There are cervical collars out now that cool at the carotids and that is supposed to help too. So why have it in the helmet? I would much rather spend the money on a really good helmet than something that may decrease impact absorbation by having a cooling gel.
It seems like a good idea I guess if you are in the middle of nowhere and crash, but I'm not convinced in the prehospital area. For that matter I could break a cold pack and wrap your head in them.
Just my thoughts. adal
