Flashcards in Emergency Deck (20):
1

If a previously stable chest trauma suddenly dies?

Suspect air embolism

2

What is the gold standard for evaluation of an aortic disruption?

Aortogram

This injury is often related to 1st/2nd rib, scapular, and sternal fractures

3

MVA pt presnts with multiple fractures. Hours later he gets a fever, respiratory distress, and a rash of small red/purple macules on his arms and chest.

Dx?

Fat embolism (long bone fractures!)

4

GCS

INtubate

5

Tx for the following arrhythmias:
P.E.A.
V fib or pulseless v.tach
SVT
AF/flutter
bradycardia

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

6

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

7

Differentiate 1st
2nd
3rd degree burns

1st - only the epidermis. no blisters - basically a sunburn
2nd - epidermis and partial thickness dermis are involved. blisters
3rd - epidermis and full thickness dermis and potentially more. White, painless, charred looking

8

BSA estimation in adults

Rule of 9's:
Head and each arm = 9%
back and chest each = 18%
each leg = 18%
perinuem = 1%

9

What bugs cause infection in burn patients?

pseudomonas or gram + cocci

10

What is one drug class you avoid in hypovolemic shock?

Kill skunks, raccoons, foxes, bats and test them for rabies

13

When to use hyperbaric O2 in smoke inhalation?

If pregnant, CNS/cardiac ischemia signs

Everyone else can get 100% O2 until they are asymptomatic and their levels of COHb fall

14

Wierd complications in bites/stings:
spider:
scorpions:

spiders = hypocalcemia
scorpion = CNS nerve dysfunction

15

Rabies tx?

If never vaccinated - you get IVIG and 4 doses of vaccine
If vaccinated previously - you get 2 doses of vaccine

20

Tx for withdrawal:
ETOH
Barbiturates
Benzodiazepines
