L12: Anesthesia & Disease (Shih)

Question 1

complications of upper airway disease

Answer 1

• prone to hypoxia
• distress (catecholamine)
• prone to obstruction (pulm edema)

Question 2

graph slide 4

Answer 2

:)

Question 3

pulmonary disease

Answer 3

• chest trauma - pneumothorax
• upper airway obstruction
• pneumonia/pulm. edema
• correct underlying dz!*

Question 4

concerns w/ pulm. dz

Answer 4

hypoventilation
hypoxia
most drugs dec. ventilation
change in compliance
inc. pulm. resistance
accumulate secretion

Question 5

what drugs to give pulm. dz patients

Answer 5

low dose opioid
propofol (?)
give O2 and assist ventilation

Question 6

how to alleviate mitral valve disease

Answer 6

(b/w LA and LV)
keep patient tachycardic and mildly vasodilated so there is less time for blood to fill ventricle and will preferentially go into aorta instead of back into LA

Question 7

concerns w/ cardiac disease

Answer 7

low oxygen delivery
prone to arrhythmia
prone to fluid overload
most anesthetic agents depress CV (except for etomidate!)

Question 8

drugs for cardiac disease***

Answer 8

PRE OXYGENATE
opioids
etomidate
low inhalant delivery

Question 9

For cat with HCM, what is WORST to happen during anesthesia?***

Answer 9

vasoconstriction

tachycardia

Question 10

Mitral regurge***

Answer 10

pre oxygenate

use atropine, opioids, etomidate

Question 11

HCM***

Answer 11

decrease stress

use opioids, dex, etomidate

Question 12

dog w/ low BUN and TS, seizures, and normal liver panel may have:

Answer 12

PSS

Question 13

labwork for liver disease***

Answer 13

US, neuro exam
chemistry profile***
clotting factors

Question 14

drugs for liver disease***

Answer 14

opioids, midazolam
propofol
remifentanyl + isoflurane
fluids: FFP, hetastarch, glucose (fluids w/ protein to prevent pulm. edema)

Question 15

drugs to avoid w/ brain disease***

Answer 15

drugs that cause:
vomiting
excess sedation (-->hypoventilation)
increase ICP (ketamine, halothane BAD!!!)***
-propofol, thiopental GOOD
