well its not about blindly following protocol
Like you said, significant moi, altered, and obvious trauma to the face/head unknown, was apparently unwitnessed
The chance of spinal injury is high(my speculation) and your right, assess Just your speculation. You're stuck on MOI. Assessment will generally yield a physiologic or anatomic problem, if present.
But even without current deficits, I would still want to immobilize(at least a collar) so that nothing gets worse while moving him, and then he shows deficits and such
Because he's altered, you cant reliably palpate his spine for pain(depending, I wasnt there but this could be true) and even with no step ups or drop offs there can be things that are there that we cannot see or feel
Thats the whole reason we take the precautions, so the ER doc can determine when to safely abandon precautions
I dont mean that every little fall or trauma is getting precautions, if its no big deal and they arent complaining of neck or back pain yadda yadda then i would rule it out and go, use our judgement and all
I really like your point about reading the moi, thats a great point that not a lot of people get
