GA Flashcards
drugs to use IV during induction
thiopental
valium/ketamine
propofol
telozol
when giving IM..
2-3x the IV dose. use with kittens and feral cats
inhalation drugs used
isoflurane
sevoflurane
rapid acting
induction chamber
used for uncooperative, small animals
disadvantages of induction chamber
difficult to monitor HR and respiration
may vomit
what to monitor during induction
HR, RR, pulse quality, anesthetic depth, MM/CRT
Vital signs HR
K9- 60-70 bpm
feline- 100 bp
ranges under anesthesia
K9- 60-150
feline- 120-180
ranges awake
K9- 60-180
feline- 120-220
methods of monitoring
direct palpation
stethoscope- auscultate &esophageal
heart monitors
EKG
where to monitor pulse quality
lingual
femoral
carotid artery
pedal artery & aural
significance of CRT
reflects perfusion of tissues
check for pigmented gingiva
tongue, cheek, conjunctiva of lower eyelid, prepuce/vulva
RR minimum acceptable
8/bpm. Sx- 10-20 bpm
Normals
K9- 10-30 bpm
feline- 25-40 bpm
methods of monitoring RR
reservoir bag
movement of chest
apnea monitor
what drug helps stimulate breathing response
Dopram (doxapram)
most common reason for complication during anesthesia
thermoregulation
factors that contribute to hypothermia
shaving pt cannot generate heat incision cools organs to room temp metabolic rate decreased vasodilation
who are predisposed to hypothermia
pediatrics/geriatrics
if they become cold
prolonged recovery
liver metabolism slows
hyperthermia
AKA malignant hyperthermia
affects swine
ketamine, halothane
succinylcholine
Malignant hyperthermia
triggered by most inhalants
heat generated by skeletal muscles
hypercapnea, hyperthermia, hyperkalemia
Inheritable
what should be used in combo with vital signs
reflex assessment
reflex depth indicators
muscle relaxation
heart/respiration rates
pupil size
eye rotation
5 common reflexes
palpebral, swallowing, pedal, pinna, laryngeal
4 other reflexes
muscle tone, jaw tone, anal sphincter tone, eye position & pupil size
tilt table for larger dogs to what degree
15 degree tilt
length of recovery depends on 6 things
length of anesthesia, condition of pt, type & route of anesthesia, temp, breed,
our role- monitor…
vital signs q 5min
reflexes q 10min
MM & CRT
administer O2 for how long
5 min after inhalant is shut off or until animal swallows
