Written Exam - Companion Animal Anesthesia Flashcards
what is the equation for ensuring the amount of oxygen available in your machine?
time (hr) = PSIG / 200 X flow rate (l/min)
if your anesthesia machine is leaking, where do you check?
connection points - circuit, inlet & outlet ports of the vaporizer, & common gas outlet
gasket leaks/cracks in components - soda lime cannister seal, screw tops of inspiratory/expiratory valves, & is the vaporizer filling port closed?
pinholes/tears - bag & circut
what are the oxygen rates used in a circle system for most patients?
60 ml/kg/min for the first 15 minutes & 30 ml/kg/min thereafter
what are the oxygen rates used in a non-rebreathing system for animals < 5-7 kg?
200-300 ml/kg/min
what is the minimum oxygen flow rate for vaporizer accuracy?
500 ml/min
how do you calculate the proper rebreathing bag size?
weight in kg X 90 or tidal volume X 6
what is the recommended fasting time for adult dogs?
6-12 hours
where are some appropriate intramuscular injection sites?
epaxials, hamstrings, & triceps
where are the most common sites used for IV injections/catheters?
dogs - cephalic/accessory cephalic or lateral saphenous
cats - cephalic, medial/lateral saphenous, & occasional dorsal pedal
what are the potential benefits of premeds?
anxiolysis, analgesia, & reduction of dose in induction drugs
what is the goal of using induction drugs?
smooth induction with minimal side effects - reduce the amount of one drug, decrease side effects
________ 5 minutes prior to induction if possible with cone or hose in close proximity to the nose, but don’t if the animal is stressed
preoxygenate
what is the best way to check for proper placement of ET tube once intubated?
check the capnograph - also direct visualization
what are some possible cuff complications?
aspiration, tracheal rupture leading to pneumothorax/pneumomediastinum/subcutaneous emphysema
tracheoesophageal fistula
what are some anesthetic complications associated with vagal stimulation?
laryngospasm, bradycardia, & apnea
