Peri-op management LA Flashcards
What breed is prone to hyperkalemic periodic paralysis?
Quarter horses
Broodmares are prone to?
Osteopenia
Acarid impactions occurring which stage?
Deworming status
What are common cardiac arrhythmias for horses?
2nd degree AV block & Afib
Is is okay to preclip the area of interest in LA?
True, this reduces prep time under anesthesia
What are 4 major chemical issues with uroperitoneum?
Hyperkalemia, hyponatremia, Hypochloremic, acidosis
Acute blood loss PCV vs. Chronic blood loss PCV
Acute blood loss when PCV <20 or >30% blood volume
Chronic blood loss when PCV <15
Formula to calculate the amount of blood required
BW (kg) x 0.08 (desired PCV- recipient PCV)
/Donor PCV
Equine fasting: Food/ Water
Food: 12 hr fast with elective procedures, but never neonates ( unless DZ indicated)
H20: Always allow to circumvent impaction, unless refluxing ~ horses have minimal risk of aspiration
Ruminant fasting: Food/Water
Food: 48 hr to decrease rumen full & reduce risk of bloat; NPO (no food or water) 24 hours
Do not fast neonates (rumen is not functional yet, so milk does directly to abomasum)
Goal of anesthesia induction
5 legged stance (nose to ground)
Two common nerves impacted by excess pressure from surgery?
radial & facial
Leg positioning in lateral recumbency & dorsal recumbancy?
Lateral- dependent forelimb pulled forward (support weight of upper limbs & protect down eye)
Dorsal: hind limbs in flexion (well padded trough)
Post- op recovery positioning: horse vs. ruminant
horses can be placed lateral to recover, BUT ruminants must be kept sternal so they do not regurgitate
You should evaluate surgical site for redness? True/False
False- you should evaluate for heat, pain, swelling, discharge, drainage, suture intact
