Q

What are some general questions you might want to ask your pt as part of the neuro exam?

A
  • Have you ever had a sz, stroke, or paralysis?
  • have you ever been diagnosed as having a tremor or parkinsons dx?
  • have you ever had numbness, tingling, or “pins-and-needles” in your arm or leg that has lasted more than 2 hours?
  • Have you ever had nerve injury, MS, or any other nervous system disease?
  • Have you had migraine HAs?

2
Q

What is your goal for the pre-op neuromuscular assessment?

Why is this importnat?

A
  • Goal to determine range of motion, any abnormalities or joint problems
  • This is important b/c we will take away the normal protective pain reflexes with anesthesia
    • dont want to injur them further
3
Q

How do you assess the temporomandibular joint?

A
  • Place tips of index finger just in front of the tragus of ear, ask pt to open mouth
  • fingertips should drop into joint spaces as mouth opens

  • snapping and clicking is normal
  • ask pt to open and close mouth, protrude and retract jaw and side to side
4
Q

How do you assess the cervical spine?

6
Q

What is thoracic outlet syndrome?

why do we care about this?

A
  • compression of brachial plexus and subclavian vessels near the first rib
