Anesthesia & ECC Review Quiz Flashcards
what is the recommended ventilation rate during CPR in the dog
8-10 breaths/min
what is the minimum gas flow rate for a 5 kg dog connected to a Bain circuit
1.0 L/min
non rebreathing fresh gas flow rate must be at least 200 mL/kg/min
at what rate would you administer LRS during routine anesthesia in a healthy dog or cat
3-5 mL/kg/hr
what is the recommended compression rate and duration of compressions per cycle during CPR in dogs
rate: 100-120 compressions/min
duration: 2 minutes compressions, 10 sec ECG reading
what is the fluid deficit of a 30 kg dog estimated to be 8% dehydrated
30 x 0.08 = 2.4 L
replace with isotonic crystalloids
when measuring blood pressure with a doppler and occluding cuff, a reading below what value is considered hypotensive?
systolic < 90 mmHg
what is the MAC of isoflurane in a dog
1.3% atm
what is the full shock dose of isotonic crystalloids in a dog
80-100 mL/kg in dogs
40-50 mL/kg in cats
one hour after giving a 2 L bolus of isotonic crystalloids to a 30 kg dog, what volume of that fluid will be remaining in its IV space?
2 L bolus –> will distribute to ECF
ECF: 25% IV, 75% interstitial
25% of 2 L = 0.5 L remains intravascular
NONE distributes intracellular because fluids are isotonic
if a dog is on a circle system with vaporizer set at 3%, O2 at 500 mL/min, how do you adjust O2 flow in order to increase anesthetic depth of the dog?
increase the O2 flow rate - will increase delivery of isoflurane to the patient
for non-invasive BP measurement, the width of the cuff should be x% of the circumference of the limb
40%
if too big: will underestimate
if too small: will overestimate
which 2 ECG rhythms are considered shockable during CPR
- ventricular fibrillation
- pulseless ventricular tachycardia
what is a long acting, non-reversible sedative with variable efficacy
acepromazine
what are 3 common and useful signs of anesthetic depth in dogs and cats
- eye position
- jaw tone
- palpebral reflex
a non-invasive monitor that may be useful to detect signs of low PaO2 during post-anesthetic recovery is…?
pulse oximeter
NOT the most useful tool for anesthetic procedures because patient is breathing 100% O2
which alpha-2 agonist is 10x more potent in cattle than horses
xylazine
you just placed an ET tube and turned on isoflurane. the dog is blinking, vocalizing, has strong jaw tone, and ETCO2 = 0 mmHg. what is the problem?
misplaced ET tube - likely in esophagus
will NOT be able to vocalize if properly intubated
which type of fluid, when administered IV, is anti-inflammatory and increases CO?
hypertonic saline (shock dose of 5 mL/kg)
what is the equation for cardiac output
CO = HR x SV
what is the acid-base diagnosis if pH = 7.40, pCO2 = 26 mmHg, and HCO3 = 15 mmol/L
pH = normal
pCO2 = respiratory alkalosis
HCO3 = metabolic acidosis
mixed primary metabolic acidosis and primary respiratory alkalosis
what are the causes of an increased anion gap metabolic acidosis
- diabetic ketoacidosis
- uremic acids
- ethylene glycol toxicity
- lactic acidosis
additional:
- methanol/ethanol toxicity
- paraldehyde
- starvaction
- aspirin
local anesthetic toxicosis is manifested by abormalities in which 2 major organ systems?
CNS + cardiovascular
CNS: seizures, tremors
CV: arrhythmias, negative inotropy, vasodilation
