Disorder of Nervous and Musculoskeletal Systems Flashcards

1
Q

Anesthetic Musculoskeletal Assessment: General Principles

A

with the induction of sedation, regional or general anesthesia we take away the normal protective pain reflexes

  • -focus on determining ROM abnormalities & joint integrity (document baseline)
  • -maintain natural ROM for all anesthetic procedures and surgical positioning (document)

Q

Assessment of tempromandibular joint

A
  • place tips of index finger just in front of the tragus of the ear - ask patient to open mouth
  • fingertips should drop into joint spaces as mouth opens
  • check for smooth ROM, swelling/tenderness, pain
  • snapping and clicking normal
  • ask patient to open and close mouth, protrude & retract (jutting the jaw forward), & perform side to side motion

Q

Hip assessment

A

concentrate on ROM that can impact positioning (think lithotomy position especially in a patient with hip hx (osteoarthritis, etc.))

  • flexion - supine pt bends each knee to chest/abdomen
  • abduction - supine pt, stabilize anterior superior iliac spine and abduct the extended leg until the iliac spine moves = limit!
