T/F: Dogs will often experience laryngospasm during intubation
Cats will often experience laryngospasm during intubation.
T/F: Rebreathing (circle) systems increase resistance for smaller patients
For this reason, we try to avoid using these rebreathing systems for small patients (guinea pigs, small cats, rats, etc.)
T/F: You should always use non-rebreathing systems for patients under 3 kg
Does this vaporizer have back-pressure compensation?
This is a non-precision vaporizer. Only precision vaporizers have back-pressure compensation
T/F: alpha-2 agonists cause vasoconstriction & increased BP, followed by a reflex bradycardia
Name the agent that is used for reversal of benzodiazepines:
Gas passing through the oxygen flowmeter is reduced from 50 psi to about ____ psi
T/F: When inflating the cuff, there should be no escape of gas from around the endotracheal tube when the APL valve is closed and the rebreathing bag is squeezed to 30 cmH2O
When inflating the cuff, there should be no escape of gas from around the endotracheal tube when the APL valve is closed and the rebreathing bag is squeezed to 20 cmH2O
When squeezed to 30 cmH2O, air should be able to escape around the tube. if not, air should be removed from the pilot balloon to prevent over-inflation
What is the mechanism of action (MOA) for Acepromazine?
Dopamine (D1 and D2) receptor antagonist
How many liters of oxygen can fit in an H Cylinder?
What stage of anesthesia is considered anesthetic overdose?
T/F: Anal sphincter tone is a good indicator of anesthetic depth
Tight in Stage II; relaxes thereafter
If the patient is holding their breath out of excitement, which stage of anesthesia is the patient likely in?
T/F: Charcoal absorption systems are useful because they absorb halogenated anesthetic gases, N2O, and CO2
Charcoal absorption systems absorb halogenated gases (iso, sevo, des), but do NOT absorb N2O or CO2
T/F: Butorphanol is a partial mu agonist and an antagonist at kappa receptors
Buprenorphine is a partial mu agonist and an antagonist at kappa receptors
Butorphanol is an agonist at kappa receptors and partial mu receptor agonist/antagonist
T/F: Precision vaporizers can be used with rebreathing or non-rebreathing systems
T/F: Doppler provides reliable detection of systolic pressure, but is generally unreliable for diastolic pressure
T/F: Nitrous oxide can produce general anesthesia on its own
What is the SVP for Isoflurane at 20oC?
The check valve prevents transfilling of one tank to another. If this valve breaks, what would happen to the temperature as a result of rapid transfilling?
Temperature would increase
**risk of FIRE**
Would these hoses be used for re-breathing or non-rebreathing systems?
Name the agent that is used to reverse pure mu and mixed agonist/antagonists because of its high affinity for mu and kappa receptors
What is the mechanism of action (MOA) of barbiturates?
↓ GABA dissociation from GABAA receptor
Direct activation of GABAA receptor Cl- channel
T/F: Propofol is a rapid-acting, long duration induction agent
Propfol is rapid-acting, ultra-short duration (<20 mins)
What is the mechanism of action of Propofol?
Enhances inhibitory effects of GABA at GABAA receptors
Induction and maintenance of general anesthesia with intravenous drugs is termed:
Total Intravenous Anesthesia (TIVA)
Simultaneous use of injectables and inhalant for general anesthesia is termed:
Partial Intravenous Anesthesia (PIVA)
Plasma concentration (Cp) of IV anesthestic drugs is at 90% of Cp steady state after ____ half-lives
Plasma concentration (Cp) of IV anesthestic drugs is at 90% of Cp steady state after 3.3 half-lives
Clearance = dose/AUC
This is not a question, but remember it anyway.
What is the consequence of leaving the APL closed for a long period of time?
Build of pressure leading to barotrauma
