A
American Quarter Horse
2
Q
broodmares susceptible to osteopenia
A
:)
3
Q
how long should adult ruminants be fasted?
A
48hrs, NPO 24hrs.
- horses typically NOT NPO before sx!*
- do not fast neonate ruminants (rumen not functional)
4
Q
pre-op patient assessment
A
- PE including re-breathing and thorough MS system exam
- hydration status
5
Q
2-3 sec. skin tent –>
A
4-6% dehydration
6
Q
3-5 sec. skin tent –>
A
7-9% dehydration
7
Q
> 5 sec. skin tent –>
A
> 9% dehydration
8
Q
death rate for healthy horses in anesthesia
A
1/1000
9
Q
factors influencing anesthetic risk
A
age
type/duration of sx
time of day
weight
10
Q
anesthesia risks
A
fractures
myopathy
neuropathy
anesthetic death
11
Q
Fast horses?
A
- only for certain elective procedures (ie. laparoscopy)
- never in neonates unless dz indicates
- access to water unless refluxing (restriction can predispose impactions)
- minimal risk of aspiration
12
Q
nasogastric tube
A
- indwelling during induction and sx of horses w/ gastric distention/reflux
- decreases risk of gastric rupture/aspiration
- removed for recovery
13
Q
Pre-op fracture stabilization:
A
- rads
- Modified Robert Jones
- Kimsey splint for fractures/luxations of the fetlock and distad
- fractures of metacarpal/metatarsal bones and proximad require alternative splinting
14
Q
induction of anesthesia
A
- flush mouth w/ water to remove food
- pre-sedate to achieve 5 legged stance
- position against wall
- calm/quiet area
15
Q
myopathy results from:
A
ischemia
