what are the three broad categories of anesthesia?
general anesthesia

local anesthesia
what prevents pain upon awakening from general anesthesia?
analgesia given while under
what are the three main types of general anesthetics used in veterinary medicine?
volatile anesthetics
total intramuscular anesthesia (TIMA)
total intravenous anesthesia (TIVA)
is there total block of pain with sedation?
no
what is infiltrative local anesthesia?
widely infuse in a local area
what are the positives of local anesthetics with general anesthesia?
lower doses of general anesthetics
can produce desensitized surgical wound so more comfortable waking up
how does general anesthesia impact blood pressure?
decreases heart rate and contractility
vasodilates
what patient protective mechanisms does general anesthesia interfere with?
musculoskeletal injury
no shivering
no blinking or lacrimation
lifting by abdomen risks organ trauma
what can errors in anesthesia equipment lead to?
incorrect or multiple inhalants delivered to patient
incorrect medical gas delivered to patient
how can there be small amounts of waste volatile gas exposure?
machine leaks
exhaled by patients recovering from anesthesia
what parts of the anesthesia system limit exposure?
anesthesia machine
vaporizer
breathing system
endotracheal tube
what does general anesthesia do?
suppresses central nervous system
unconsciousness
total lack of perception of sensation
cortex does not respond to pain signals, but brain stem may
pain not perceived until awakening
is there total block of pain when sedated?
no
what makes surgery possible without general anesthesia?
local anesthesia
