  1. Who does the Preop Eval/Assessment/Anesthetic Care plan?
    ›In the ideal world, the provider who will administer the anesthesia!!

    • In the real world, the patient is often seen ahead of time by a RN or NP or anesthesia provider in a preoperative assessment clinic 
    • *Helps to ID patients who may need to cancel or delay surgery so OR runs efficiently*
  2. What does the Preop Eval Involve?
    ›Review of the surgical diagnosis, involved organs/systems, & planned procedure

    ›Interview (subjective data, also ROS)

    ›Physical exam (objective data)

    ›Medical record review (current & past)

    ›All of this determines patient’s physical & mental status
  3. Besides ›Medications, ›Drug allergies, & ›Cigarettes, alcohol, illicit drugs we ask about previous anesthesia/surgical experiences. Why?

    •    -›Postop pain mgt “PCA/Epidural”

  7. Explain Informed consent
    • ›Discuss alternatives (spinal vs GA)
    • ›Potential complications

    ›Establishes a trusting provider-patient relationship

    ›Significantly diminishes patient anxiety

    Measurably influences postop recovery & outcomes
  9. TRUE or FALSE. ASA status is  ›Imprecise,
    subjective, inconsistent.  ›ONLY the higher ASA class roughly predicts anesthetic risk
  10. Name the 5 ASA physical status classifications.
    ›Class 1—Healthy patients, no medical problems

    ›Class 2—Mild systemic disease (smokers)

    ›Class 4—Severe systemic disease that is a constant threat to life

    ›Class 5—Moribund, not expected to live 24 hours regardless of surgery
  11. Why is an E sometimes added to the end of an ASA classification?
    ›To denote an emergency surgery
  12. Is there a class 6 ASA?
    ›Organ donor
  13. How important are the ASA classifications?
    ›In addition to faciltiating communication about the patient, it effects reimbursement for anesthesia services
