Pre-Anesthesia Assessment (including CV) Flashcards

1
Q

Identify the Major goals of the pre-anesthesia evaluation

A
  • optimize pt care and satisfaction
  • reduce periop morbidity/mortaity
  • minimize surgical delays/cancelations
  • determine ideal postop pt disposition (home, Inpatient, ICU)
  • evaluate pt health status and preop testing needs
  • formulate a plan (can obtain consent)
  • ensure time efficient, cost effective pt evaluation

Q

what are pros of a dedicated pre-op clinic (PAT)

A

Q

why look at the medical record if you can interview the pt

A

Q

guidlines for ordering pre-anesthesia lab test

A
  • cost effective
  • positive benefit risk ratio
  • ready for evaluation prior to sx
  • test should yeild information that can’t be obtained from h&p
