Q

What are the MC local anesthetic? What can be added and why?

Lidocaine and bivocaine

can add Epi to increase duration of anestehsia, control wound bleeding, and slow systemic absorbtion

pull back to make sure you did not hit an artery

17
Q

When should you avoid epi?

A

digital vascular injury; in patients with vascular disease, such as Raynaud’s or Berger’s disease; or in other conditions in which end-arterial vascular supply is problematic

18
Q

Three indications for topical anesthecicas

A

Topical anesthetics are used in three major situations: on intact skin before dermal instrumentation, applied to intact mucosa, and placed on open skin for pain control or before wound repair.

19
Q

What are the indications for regional anesthetics? What do you need to do this

A

complicated lacerations, abscesses, fractures, debridement, and dislocations

use for peripheral nerve blocks w/ or w/out US (lidocaine, etc)

digital block is an example

20
Q

What are the two different digital blocks

A

Flexor tendon sheath block: not as well, but once (put in between the double crease of the finger)

Digital nerve block: 4 injectons (assess cap refill/sensation before block)

21
Q

What is considered chronic pain and what should be ruled out?

A

3 months, pain that persists beyond the reasonable time for an injury to heal, or pain that persists 1 month beyond the usual course of an acute disease

r/o acute pain or limb threatening condition

look for change in baseline pain in the ER

remember, opioids are NOT indicated post-ER chronic pain

Xray coupled with an excellent neuro and MSK exam

26

What is the management of lower back pain

A
  1. Restriction of activity

  4. Monitor symptoms for 4-6 weeks
