You have a 25 year old male who is unresponsive. No medical history, medication bottles., bystanders, bracelets, etc. around; just a dark alley and an unresponsive man. He has a stab wound to his upper right abdomen. Vitals are respirations 8 shallow, Blood pressure is 100/60, pulse is 126 rapid, skin is cool.
What would you do in this situation?
Well, the idea that he is tachycardic but bradypneic is a little baffling, but hey, medicine is like that, right?
So anyway, my answer would be (in likely order of findings):
test LOC. > partner on C-SPINE.
A.B.C. > Skin & O2 > grab sandbags from unit > OPA and BVM to partner.
RBS > find puncture (or knife?) in RUQ > radio for immediate police backup > clean wound with sterile H20 or N/S and dress.
Cervical collar > package pt on clamshell or spineboard (full immobilization) > load into bus.
Partner continues bagging > check LOC, ABC > perform Vitals > check treatment > place pillow under lower legs > prime a bag> take over bagging and go.
If BP was less than 90 I would start an IV, but I wouldn't delay at the scene for one unless the pt was hypovolemic. I'd just prime a bag instead, only takes a couple of seconds and is ready for me if I need to start a line enroute. My main consideration for the moment is supporting respirations. Once resps and HR both go brady, then cardiac arrest is imminent.
I immobilize because there is no history, as should everyone else; if you don't know what happened to a pt, then you don't know for certain that they don't have a spinal injury. I think people are too lax on that point too, forgetting that we don't look for reasons to spinal trauma pts, we look for reasons not to.
I also raise the legs in the bus because it is more comfortable for a pt with an abdominal injury if for no other reason, but shock considerations are good reasons too.
