I'll try to do it concisely (note, please read the above responses, but read below it you can't fully digest all the info):
Accessory pathways are made of nerve fibers. The AV node is made of muscle. This is by design, because it allows for conduction to slow down from the atrium to the...
I agree both to this, and your previous sentiment about taking minimalist approaches to airways that need tubes.
Not everyone needs a tube, or RSI for that matter. But when you need RSI, you NEED it. Over the years there's been many more "risk adverse" adjustments to airway guidelines (which...
I agree wholeheartedly. I came back singing the praises of ketamine's versatility, only to he greeted with "that's a cat tranquilizer". Now it's the goddamned flavor of the month. There were instances where I would have much favored propofol, but didn't feel like waiting 20 mins for someone to...
I've used it in serial boluses, and maintenence infusions, in conjunction with versed.
I've used it extensively for induction/maintenence, PSA for fracture reductions, chest tubes, and minor surgical procedures, difficult dental extractions, and low-dose for tourniquet pain that was not...
I've found that printing the strip helps with seeing the shark fin better as well; sometimes you see shark fin wave forms that end up being normal after you print em out.
There's tons of things that we do in the field that have shoddy scientific backing, but at least in the spectrum of allergy/anaphylaxis, they should most definitely get solu medrol.
Following the epi/benadryl, inhibiting mast cell formation (and thus preventing additional histamine release) Is...
They're passable at best. Half the time they turn the airway into a bloody mess. You can pass an OG tube through them though, and we get decent C02 in cardiac arrests most of the time.
The straps that come with them are garbage though. Tape the crap out of em to secure it.
Anorexia is an excellent indicator for appendicitis. Distension may be from the associated peritonitis. But, there's about 1834 other things that cause anorexia and peritonitis, so until we get CT scanners and I iSTATs, treat for the worst case scenario-----
..... which is probably the same...
A good, quick tool for subarachnoids is keurnig's sign, which is "guarding" with the legs (much like in abdominal injuries) with neck flexion. As a rule of thumb subarachnoids will present much like afebrile Meningitis, outside of history taking.
80% of our seretonin is found in the gut. Zofran is so popular because it antagonizes those peripheral seretonin receptors, which in turn prevents vagus nerve stimulation. As a contrast, drugs like Phenergan work peripherally in the gut as well as centrally in the CTZ.
As far as I'm aware...
You've gotta try to protect the kidneys in any shock state; even more when theyre in any kind of renal failure. The old mantra "brain, heart, kidneys" still holds true, and probably always will.
Letting them become ischemic/lower GFR further is way more dangerous than "overloading" them...
