Fat embolism (long bone fractures!)
Tx for the following arrhythmias:
V fib or pulseless v.tach
P.E.A. = CPR and epi/vasopressin
V fib or pulseless v.tach = CPR and defibrillate, followed by epi
SVT = unstable, then cardiovert. stable, then positioning and then adenosine
AF/flutter = unstable, then cardiovert. If stable, control rate and anticoagulate if duration is >48h
bradycardia = atropine if symptomatic
Think ischemic colitis if...
pt recently got treated for AF or AAA who presents with bloody stool and abdominal pain out or proportion to the exam
