39
What is one example of a dog breed that ages quickly?

40
What consideration should be made for the heart when choosing an anesthetic agent?
decreased cardiac function calls for isoflurane (decreased heart effects)
41
What is the role of the liver in metabolizing anesthetic agents?
metabolizes injectable agents
42
What is the role of the lungs in metabolizing anesthetic agents?
removes anesthetic gas through blow off
43
What is the role of the kidneys in metabolizing anesthetic agents?
excretes (does not metabolize!) injectable agents
44
What is different about the kidney's metabolism and secretion mechanism in the cat?
kidneys completely remove the agents
45
Explain anesthetic redistribution.
o Anesthetic goes from the machine to the patient’s lungs where diffusion across capillary walls increases the concentration in the blood stream o The anesthetic then travels to the highly vascularized tissues such as the brain o Then the agents are pulled into the fats and muscle of the body which are poorly vascularized o This decreases the concentration in the brain causing the animal to “wake up” even though there is still adequate anesthetic in the body o The liver cannot metabolize the agents fast enough to eliminate the drugs completely before redosing
46
Why do older dogs have a higher hypothermia risk?
lost insulation (low body fat content)
47

63
What is the anesthetic drug of choice for sighthounds?
propofol
64
Why is propofol the drug of choice for sighthounds?
o Sight hounds lack body fat so drugs will have a larger effect on them o Propofol is eliminated quickly through liver metabolism o Because there is less fat and muscle to absorb the drug from the blood stream, rapidly metabolized drugs are a good thing for sight hounds (little to no redistribution)
65
What drug is not given to sighthounds?
barbiturates because there is no redistribution to decrease concentration of the agents in the brain and blood
