Exam Flashcards
what do you do if hypotensive and bradycardic
decrease inhalant if deep, maybe anticholinergic
if patient is hypotensive and tachy/normocardic
decrease inhalant if deep, give fluid bolus
if unresponsive, dopamine or dobutamine CRI
Type of surgeries that affect infection risk
clean-non-traumatic elective
clean/contaminated- controlled entry into GI, genitourinary or respiratory tract
contaminated- fresh traumatic wounds, spillage from tracts
dirty- old wounds, perf, abscess
7 halsteads principles to reducing infection
minimize tissue trauma
control hemorrhage
preserve blood supply
asepsis
minimize tissue tension
appose tissue accurately
minimize dead space
autoclave
sterilizes using a high temperature pressurized steam to denature bacterial proteins
(steam, pressure, temperature, time)
ethylene oxide vs vaporized hydrogen peroxide chemical sterilization
ethylene oxide takes forever and is combustible and toxic, peroxide is still irritating to eyes, but takes less time
mayo vs metzenbaum
mayo blunt dissection, metz more delicate
alcohol based scrubs
requires shorter contact time, more cost effective
where can you not readjust towels once placed?
TOWARDS the incision
prognosis scale
good- potential for complications
fair- serious complications possible, recovery may be prolonged or animal may not return to presurg function
poor- sever complications, death during or after procedure is likely
guarded- outcome unknown
ASA rating
I- healthy
II- localized or mild systemic disease
III- severe systemic disease
IV- disease is life threatening
V- patient not expected to live more than a few hours with or without surgery
big 4
PCV, TS, Azo, BG
what can cause increased or decreased BUN
increased- shock, CKD, urogenital obstruction, recent meal, GI ulcer
decreased- liver disease, shunt, low protein diet, PU/PD
CDV clinical signs
GI signs with concurrent or previous respiratory disease, “chewing gum fits”
