Injectable Gen Anes (Dissociatives) Flashcards
Dissociative anesthetics are called
Cyclohexamines
an animal in a dissociated state is in a ______ state
cataleptoid state (cataplexy)
what is a cataleptoid state (what is seen in animal)
patient unresponsive, muscles rigid, unaware, good superficial analgesia, no visceral analgesia
in a cataleptoid which reflexes are still present
PLR, palpebral, swallowing
characteristics of an animals eyes in a cataleptoid state
open, eyeball rotation centers pupils, fixed dilation
dissociative anesthetics affect on cardiovascular system
stimulate sympathetic NS causing increased HR, increased CO, increased Blood Pressure, may decrease intropy (arrythmics have higher risks)
define intropy
strength of heart contractions
dissociative anesthetics affect on respirations
v little depression, high doses cause apneustic breathing, increase in respiratory secretions
define apneustic breathing
pause at end of inspiration, short expiration, appears to hold breath
why you should not use dissociatives in patients undergoing CNS procedures
dissociatives lower seizure threshold
what occurs during recovery from these dissociative drugs (unique behaviors)
face-pawing (may be because of hallucinations)
Nystagmus
why we use anticholinergics before dissociative drugs
In what case would we not use the two
anticholinergics cause a decrease in salivation, dissociatives cause an increase.
both increase HR, don’t use in heart patients
2 dissociative drugs
Ketamine hydrochloride and Tiletamine (+zolazapam= telazol)
only instance in which a dissociative would be given PO
Ketamine for fractious cats
only instance in which a dissociative would be given SQ
Telazol (rare)
