Bovine Flashcards
(117 cards)
three economic values that dictate if surgery will be preformed
- High producing Dairy Cattle
- Registered Breeding Stock
- Pet animals
two main ways to preform bovine surgery
standing or GA
sedation with forced recumbency
casting
Majority of Surgeries done this way
standing
standing surgeries are done with a combination of what three things
restraint
sedation/tranquilization
local/regional block
what should be kept in mind in bovine surgeries
withdrawal times (for butchering)
seven things that restraint for standing surgery depends on
Facilities
Personnel available
Duration
Patient factors (temperament) Anatomical location
Anticipated pain
General health of patient
how long should food be withheld before standing surgery
12-14 hours
how long should water be withheld from adult cattle before standing surgery
6 hours or less
preferred local anesthesia drug (still toxic but the “safest” one)
lidocaine
toxicity signs of lidocaine in bovine
hypotension
sedation
resp. depress
muscle twitching
convulsions
it is best to dilute lidocaine to what percentage
2%
pain control for flank incisions, needs to be deposited into several layers of tissues
L Block
L Blocks are deposited in what shape
inverted “L”
pain control that is given in spinal roots
paravertebral block

how much local anesthetic is given in the lateral approach of a paravertebral block
10-20 ml per site
pain control for dehorning
cornual nerve block
how many nerves do cattle have supplied to each horn
one (between eye and horn)
pain control for distal limb - two names
Bier block
or
intravenous regional analgesia
where are Bier blocks given in distal limbs
metatarsal/metacarpal veins
