If you give a little versed and the patient gets sleepy, you can bill that as General - even though that is not the actual definition.

A

Cyclopropane
(Slide 21)

55
Q

Describe stage I of anesthesia and the 3 planes involved.

Stage I: beginning of induction of general anesthesia to loss of consciousness

1st plane: no amnesia or analgesia (Remembers everything, still hurting & follows commands!)

2nd plane: amnestic but only partially analgesic (Can still remember and hurt a little)

3rd plane: complete analgesia and amnesia (Does not remember hurting & not hurting, might remember counting backwards/etc.)

(Slide 34)

56
Q

(Slide 21)

58
Q

4000 BC - 400 BC.

Carotid compression was used to briefly knock you unconscious. Acupuncture was also a form of treatment.

(Slide 7)

69
Q

During the time of Hippocrates, around 400 BC, who was the priority, the patient or the surgeon?

76
Q

What does the word “ether” mean?

A

Ignite. 💥
It would explode

(slide 10)

77
Q

Why did inhalation anesthetic agents come about first before IV anesthetic agents?

A

Because the IV was not created yet.

(slide 10)

78
Q

The Middle Ages brought about some advances in anesthesia, such as inhaled agents. How were inhaled meds given, and what do we call this method of administration?

A

Soporific is the term used for sponges that you place medicine on and then inhale, with the intention of going into a deep sleep. (Slide 9)

79
Q

Why did “Diethyl ether recreational parties” become so popular at the time?

A

Because of the high tax on whiskey and alcohol. Diethyl ether was cheaper and easier to get high on.

(slide 10)

80

A

Humphry Davy

(slide 12)

88
Q

Why was Nitrous not taken “seriously” and initially overlooked in its early aesthetic/pain control days resulting in it becoming a recreational entertainment?

A

Because it did not prevent the patient from moving.

(slide 12)

89
Q

What dentist used Nitrous during tooth extractions on patients (and on self) where his patients demonstrated they had no “recall” of pain/injury?

A

Horace Wells

(slide 13)

90
Q

The early use of Nitrous effects on amnesia was argued by some to be due to what and not actaully from the drug’s anesthetic effect iself?

A

Hypoxic events. Because Nitrous was being given with just room air.

*and now we know that N2O is very water soluble and creates a huge [ ] gradient in the alveolus for O2 (reason why we need supplemental O2)
(slide 13)

decreases the amount of anesthetic needed

(slide 27)

95
Q

What was once a triad is now a “Quad-ad”, but what 4th factor was added to “Amnesia”, “Analgesia”, and “Muscle Relaxation”?
