SA Pre-Operative Patient Assessment & Preparation (20) Flashcards
Dr. Thompson
What ways do we assess a patient preoperatively?
- patient history
- physical exam
- laboratory data
- associated underlying disease
- patient stabilization
What are the “Big 4” or “Quats” that young, healthy animals undergoing elective surgery get?
- PCV (hematocrit)
- total protein (TP)
- blood glucose
- BUN
What should an animal older than 5 to 7 years get before surgery - laboratory data?
“Minimum Data Base”
- CBC and differential
- serum biochemical profile
- urinalysis
How should you assess neoplasia in a dog?
evaluate for metastasis - see if in multiple places
- thoracic imaging
- abdominal ultrasound
- lymph node aspiration
How do you evaluate cardiac disease before surgery?
- thoracic radiographs
- cardiac ultrasound scan
- electrocardiogram
How should you assess trauma patients before surgery?
- diaphragm
- pleural space
- lungs
What is ASA I?
healthy with no discernible disease - elective procedure
What is ASA II?
healthy with localized disease or mild systemic disease
patellar luxation, skin tumor, cleft palate without aspiration pneumonia
What is ASA III?
severe systemic disease
pneumonia, fever, dehydration, heart murmur, anemia
What is ASA IV?
severe systemic disease that is life-threatening
heart failure, renal failure, hepatic failure, severe hypovolemia, severe hemorrhage
What is ASA V?
patient not expected to live longer than 24 hours with or without surgery
endotoxic shock, multi organ failure, severe trauma
What is E in ASA?
emergency
A skin tumor is ASA ___
II
A heart murmur is ASA ___
III
A declaw is ASA ___
I
Hepatic failure is ASA ___
IV
Severe trauma is ASA ___
V
Endotoxic shock is ASA __
V
How should you determine surgical risk?
consider history, physical examination, and laboratory tests
risk of the surgical procedure may outweigh its potential benefits
What is a “Fair” prognosis of surgical risk?
serious complications are possible, but uncommon
recovery may be prolonged
animal may not return to its pre surgical function
What is a “Poor” prognosis of surgical risk?
underlying disease or surgical procedure is associated with many or severe complications
recovery is expected to be prolonged
likelihood of death during or after the procedure is high
unlikely to return to pre surgical function
What is a “Excellent” prognosis of surgical risk?
potential for complications is minimal
high probability that the patient will return to normal
What is a “Good” prognosis of surgical risk?
some potential for complications
high probability of a good outcome
What is a “Guarded” prognosis of surgical risk?
when the outcome is highly variable or unknown
