Q

What was Agatha Hodgins notable for?

A
  • Opened 1st nurse anesthesia school
  • Taught France in WWI
  • Founded AANA
22
Q

What was the issue with Cyclopropane use?

A
  • Violently explosive
23
Q

Why is halothane obsolete?

A
  • Long induction/emergence
24
Q

Contrast Isoflurane, Sevoflurane, and Desflurane.

A
  • Isoflurane: longer onset/emergence
  • Sevoflurane: intermediate onset/emergence
  • Desflurane: rapid onset/emergence
25
Q

Which volatile anesthetic has the highest vapor pressure? What does this mean?

A
  • Desflurane
  • High vapor pressure means it evaporates very quickly.
26
Q

Which volatile anesthetic is unstable in soda lime? What does soda lime do?

A
  • Sevoflurane
  • Soda Lime is a CO₂ absorbent.
27
Q

What benefits does Sevoflurane offer compared to other volatile anesthetics?

A
  • Less airway irritation
28
Q

What is the “Triad” of anesthesia?

A
  • Amnesia, Analgesia, & Muscle Relaxation
29
Q

Regarding amnesia, what neurotransmitter inhibits stimulatory transmissions?

A
  • GABA
30
Q

Regarding amnesia, which neurotransmitter stimulates inhibitory transmissions?

A

ACh

31
Q

What is the primary benefit of muscle relaxants?

A
  • Decreases the amount of other anesthetics needed (thus overall decreasing mortality)
32
Q

What new factor was added to the anesthesia triad to form “balanced anesthesia”?

A
  • Homeostasis
33
Q

Which physician had three deaths in one operation?

A
  • Dr. Liston
34
Q

What was the practice of neurolept anesthesia?

A
  • Very high doses of amnestic drugs (droperidol, haldol, etc) vs volatiles or analgesics.
35
Q

What are the three stages of Anesthesia?

A
  1. Beginning of induction of general anesthesia to loss of consciousness
  2. Loss of consciousness to onset of automatic breathing
  3. Onset respiratory paralysis (surgical plane)
36
Q

What characterizes stage 1 of anesthesia?

A

Stage 1:
- 1st plane - no amnesia or analgesia
- 2nd plane - amnestic but only partial analgesic
- 3rd plane - complete analgesia & amnesia

37
Q

What characterizes stage 2 of anesthesia?

A

Stage 2
- eyelash reflex disappears
- coughing, N/V, struggling may occur
- irregular respirations

38
Q

What planes characterize stage 3 of anesthesia?

A

Stage 3
- 1st plane - automatic respiration → eyeball movement stops
- 2nd plane - ocular cessation → intercostals start to paralyze & tear secretion increases.
- 3rd plane - pupillary dilation, desired plane prior to muscle relaxants
- 4th plane - complete intercostal paralysis → diaphragmatic paralysis (apnea)

39
Q

What characterizes stage IV of anesthesia?

A
  • Death (via medullary paralysis)
40
Q

In what stage and/or plane of anesthesia would one expect to see lacrimation?

A

Stage 3 / 2nd plane

41
Q

In what stage and/or plane of anesthesia would one expect to see onset of diaphragmatic paralysis?

A

Stage 3 / 4th plane

42
Q

In what stage and/or plane of anesthesia would one expect the beginning of total amnesia/analgesia to occur?

A

Stage 1 / 3rd plane

43
Q

In what stage and/or plane of anesthesia would one expect for the eyelash reflex to disappear?

A

Stage 2

44
Q

In what stage and/or plane of anesthesia would one expect to see total and complete intercostal paralysis?

A

Stage 3 / 4th plane

45
Q

In what stage and/or plane of anesthesia would one expect to see pupillary dilation?

A

Stage 3 / 3rd plane

46
Q

In what stage and/or plane of anesthesia would one expect to see amnesia but only partial analgesia?

A

Stage 1 / 2nd plane
