Injectable anesthetics: Dissociative anesthetics Flashcards
describe dissociative anesthesia
animal may seem awake but is unaware of its surroundings
dissociative anesthetics induce catalepsy - what is catalepsy?
animal does not respond to external stimuli and exhibits muscle rigidity
don’t give dissociative anesthetics to animals that have seizures - why?
dissociative anesthetics can precipitate seizures
effects of dissociative anesthetics (7):
- poor muscle relaxation
- swallowing and laryngeal reflexes may persist throughout anesthesia
- provide no visceral analgesia
- may produce apneustic respiration
- no cardiovascular system depression
- can possibly worsen arrhythmia
- may increase salivary and respiratory secretions
dissociative anesthetics provide (poor/moderate) muscle relaxation
poor muscle relaxation
these reflexes may persist throughout anesthesia with dissociative anesthetics
swallowing and laryngeal reflexes
describe apneustic respiration
animal breathes in, holds breath, then short exhalation
dissociative anesthetics (do/do not) cause cardiovascular system depression
do not cause
why don’t we want to give animals with arrhythmias dissociative anesthetics?
they could possible worsen the arrhythmia
what could we give animals when dissociative anesthetics cause them to have increased salivary and respiratory secretions?
anticholinergics
we use dissociative anesthetics in combination with what to minimize adverse effects?
tranquilizers/sedatives
what should we apply to their eyes, which are often open?
ophthalmic lubricant
dissociative anesthetics can cause tissue irritation when given via what route?
IM
after the use of dissociative anesthetics, animals may be hypersensitive to what during recovery?
touch, light, and sound
avoid using dissociative anesthetics in animals with
cranial trauma
