Anesthesia Lecture 5

Question 1

When surgery is complete, what should be done?

Answer 1

Turn off the iso, disconnect the patient, flush the system, reconnect and allow them to breath 100% oxygen for 1-3 mins, then disconnect the patient and turn off the machine

Question 2

Pulling the ET tube

Answer 2

Dogs= When the dog swallows multiple times; Brachycephalic= Wait until the dog can hold head up and is sternal; Cats= When voluntary movement begins or swallow reflexes

Question 3

Total rebreathing system

Answer 3

Pop-off is closed; Has increased pressure in circuit; do not respond quickly to vaporizer changes

Question 4

Cons of closed/semi-closed systems

Answer 4

Requires more skill and monitoring, risky anesthesia, increased CO2, increased pressure, slow to change in % of inhalant

Question 5

True or false: open systems have a small amount of re-circulated air in the system

Answer 5

True

Question 6

A bain system should only be used with…

Answer 6

Patients less than 7 kg

Question 7

Inhalants in order of most potent to least potent

Answer 7

Methoxy, Halothane, Isoflurane, and Sevoflurane

Question 8

Precision vaporizers work correctly when…

Answer 8

Place outside the circle

Question 9

MAC

Answer 9

Minimum alveolar concentration; the lowest concentration at which there is no response to pain in 50% of patients

Question 10

MAC for Isofluane

Answer 10

1.5 x 1.2= 1.8%

Question 11

Con of Halothane

Answer 11

Associated with malignant hyperthermia

Question 12

Characteristics of Isoflurane

Answer 12

Uses a precision vaporizer, high margin of safety, MAC= 1.2, very low solubility coefficient, low fat solubility, good choice for patients with issues

Question 13

1 pro of Isoflurane

Answer 13

99% is eliminated by the lungs

Question 14

Pro of Sevoflurane

Answer 14

Primarily eliminated from the body by respirations
