Availability of Facility
Availability of Surgeon
Patient Health Status
Ability to provide After Care
Prognosis
Economics
two types of equine surgery
standing
general anesthesia
surgery that is best for animals with extreme stress
standing
surgery that is best for animals with a history of problems with general anestheisa
standing
surgery that is best for owners with cost restraints
standing
three drawbacks to standing surgery
Surgeon comfort and visualization
Difficult to drape for sterile surgical field
Possible movement of patient
how long is grain restricted in standing surgery prep
12 hours
how long is hay restricted in standing surgery prep
2 to 6 hours
three things to do for standing surgery prep
clean surgical area
instruments available
decide on restraint (chemical, physical)
three ways to control pain in standing surgery
nerve block
field block
epidural
pain control method for standing surgery used a distal area “map” being blocked
nerve block
pain control method for standing surgery where a line of area is blocked
field block
pain control method for standing surgery that provides analgesia for Tail, perineum, anus/rectum, vulva, vagina
epidural
local anesthetic epidurals can cause a higher chance of what negative side effect
ataxia
three drugs classes used for epidurals in standing surgery
Local anesthetics
Alpha-2
Opioids
location used for epidural in standing surgery
first moveable intercoccygeal space
how long is grain and hay withheld in general anesthesia prep
12 hours
what premeds are not used in GA because they depress GI motility
atropine
how long is grain and hay withheld before GA
12 hours for both
what is not withheld before GA
water
what anesthesia drug is not recommended in horses because it depresses GI motility
Atropine
what can be done preanesthetia to decrease anesthesia time
Clip/Clean
place catheter
equipment
positioning plan
why is it important to clean the horses mouth before anesthesia
Harbors debris that would interfere with intubation
what should be protected during GA to reduce the risk of recovery accidents
legs and eyes
what two things should be done before GA to make sure the horse is safe for anesthesia
preop physical exam
lab work
what should be done preop to correct dehydration and replenish electrolytes
fluid therapy
what can happen to horses in recumbent positions under GA
compartment syndrome
what two anesthesia factors can help reduce the risk of compartment syndrome
time and depth of anesthesia
proper positioning and what can reduce the risk of compartment syndrome
cushions
what should be reduce before GA to reduce the risk of compartment syndrome
carbohydrate intake
what should be maintained during GA to reduce the risk of compartment syndrome
blood pressure
three methods for induction/maintenance of GA
Injectable INDUCTION and injectable MAINTENANCE
Injectable INDUCTION and gas MAINTENANCE
Gas INDUCTION and gas MAINTENANCE
gas induction and gas maintenance is used in what age horse
foals
