Induction Agents associated with which mechanism of action result in dose-related respiratory depression and apnea?

Enhances GABA on GABAA receptor

62

The MAC of Tingflurane is 5.4%. The MAC of Stagflurane is 3.6%. Which is more potent?

Stagflurane

The lower the MAC, the more potent the agent

63

The blood gas solubility for Tingflurane is 0.4. The blood gas solubility for Stagflurane is 1.5. Which would have a faster onset of induction?

Tingflurane

The lower the blood solubility, the faster the onset of induction

64

What is the boiling point for Desflurane?

74oF

65

Between halothane and sevoflurane, which has a higher vapor pressure?

Halothane

Desflurane > Halothane > Isoflurane > Sevoflurane

66

Between halothane and sevoflurane, which has a higher blood gas solubility?

Halothane

Blood gas solubility: Halothane > Isoflurane > Sevoflurane > Desflurane

Halothane has the highest blood gas solubility and therefore is the most POTENT

Desflurane has the lowest blood gas solubility, which means it has the fastest onset and the fastest recovery

67

T/F: The higher the MAC, the higher the potency

False!

The higher the MAC, the LOWER the potency

Potency ranking: Halothane > Isoflurane > Sevoflurane > Desflurane

68

What is the basic MAC value for Isoflurane?

1.3%

69

What is the basic MAC value for Sevoflurane?

2.3%

70

What is the basic MAC value for Halothane?

0.87%
