terminology Flashcards
anesthesia
unconsciousness produced by a controlled, reversible intoxication of the CNS
Anesthetist
any person trained to administer anesthesia
anesthesiology
study of anesthesia
anesthesiologist
a veterinarian who specializes in anesthesia
analgesia
relief of pain
Autonomic nervous system
involuntary nervous system. sympathetic or parasympathetic
anticholinergic
parasympathetic drugs block cholinergic receptors of PNS. not analgesic or anesthetic but used with it
body composition
amount of body fat or muscle
bradycardia
low heart rate
circulation
movement of blood in regular course
dissociogenics
overstimulate of CNS instead of depression. dissociated mind from body
extubation
removal of endotracheal tube
general anesthesia
state of unconsciousness produced by anesthetic agents. absence of pain over entire body
hypertension
high blood pressure
hyperthermia
high blood temperature
hypotension
low blood pressure
hypothermia
low blood temperature
induction
production of unconsciousness or anesthesia by use of appropriate agents
inhalant
absorbed through the lungs at alveolar level
intubation
insertion of tube, as into the larynx
local analgesics
analogs of cocaine. blocks transmission of impulses along nerve fiber. acts directly on a nerve to lose sensation and motor function
maintenance
after induction, enter anesthetic depth adequately for surgical procedure
MAC
deals with inhalants. measures potency comparing one agent to another
narcotic
opiates. derived from opium plant.
narcotic agonist antagonist
partial agonist. reverses narcotic sedation, and keeps pain relief
narcotic antagonist
reversal of narcotic
neuroleptanalgesia
combo of narcotic and tranquilizer. calming effect and pain relief
PPV positive pressure ventilation
“sigh” an artificial means of ventilation.
procedure
any surgical operation or diagnosis
recovery
discontinuation of anesthesia administration and the time an animal can stand and walk without assistance.
respiration
exchange of O2 and CO2 at alveolar level
respiration minute volume
Total volume X number of breaths per minute
saturation concentration
max concentration of vapor that can be reached at room temperature for a fluid in a closed container.
sedation
a mild degree of CNS depression
sedative
an agent that calms
surgical anesthesia
degree of anesthesia where surgery may safely be performed. consists of stages and planes of GA
tachycardia
rapid heart rate
tidal volume
in and out of lungs in one breath. 10-15 ml/kg
tranquilizer
sedative or neuroleptic. causes calming and decreased anxiety
unconsciousness
inability to respond to stimulus
ventilation
movement of gases in and out of alveoli, controlled by ventilizer
volatile liquids
agents stored as liquids and administered as vapor with O2
