How often do you have high-stress cases like car-crashes where patients are critical, etc? Sorry if that sounds like a stupid question, television has probably ruined my perception of the ER. Also, can you describe how much of the diagnosis process you go through as an EM? Can you diagnose complex cases or is it mostly just general diagnosing and admitting difficult cases?
1. Car crashes are protocol. ABC. Check for things that'll kill the patient first. I look for anything that obstruct airway like a facial fracture or bloody oropharynx. Then I check for breathing - mainly look for pneumothorax and flail chest. Then I check for circulatory issues such as tamponade or bleed.
Then after that - I go through a protocol for the particular injury. Imaging as needed, stabilize, transfer if needed.
2. I try to diagnose as best as I could or at least some sort of a more narrowed differential. Take for example if someone comes in with these vitals:
80/50, 130HR, 103.7, and 80yo man.
First thing I think about is sepsis. Could it be something else? Like TCA overdose? Yes.
But the common thing is to treat it symptomatically first, then treat the killers next.
This guy would get IV/O2/monitor. Cardiac tests including EKG and troponins. Then I would get basics labs like a CBC and VBG. Then I would check for sources like a UA, CXR, possible CT. I would also get blood cultures and then add on some antibiotics (go wide then narrow as inpatient). The guy would also need some IVF (2-3L) and if he doesn't respond, he would need some pressers after the 4th liter (though that may be a bit too much for an 80yo to handle). He may also need to be intubated to relieve himself of some precious energy that could be used to fight the infection instead.
After that, I'd admit to ICU. Call it sepsis until proven otherwise, the docs in the unit can figure out exactly if it was toxin mediated, pneumonia, urosepsis, or whatever else it could.
If the guy didn't have a fever, I'd probably put an ultrasound probe on the guy's IVC to differentiate between volume depleted and volume overloaded states. If depleted, I'd think sepsis vs anaphylaxis. If overloaded, I'd think thrombosis (PE) vs CHF.
Then again, it could be a red herring like spinal shock (I've seen that).
So many issues could be causing it... it's a FANTASTIC feeling to crack the case.
That's EM.
If you like that, you're made for EM.
