1
What are the aims of pre-op assessments?
To check that owner, nurse and vet are all clear about exactly what procedure is to be performed
To gather all relevant patient history and information
To check body systems specifically affected by anaesthesia and general health
To categorise the risk of anaesthesia to the patient
2
There are 5 classes of anaesthetic risk. Describe an animal in class 1 (minimal risk) and give examples of a procedure
Normal healthy animal
No underlying disease
Spey, castration
Radiograph for hip dysplasia
3
There are 5 classes of anaesthetic risk. Describe an animal in class 2 (slight risk) and give examples of a procedure
Animals with slight to mild systemic disturbances
Animals able to compensate
No clinical signs of disease
Neonates, geriatrics
Fracture without shock
Well controlled diabetes
4
There are 5 classes of anaesthetic risk. Describe an animal in class 3 (moderate risk) and give examples of a procedure
Animals with moderate systemic disturbances
Mild clinical signs
Anaemia
low grade renal disease
low grade heart murmur
5
There are 5 classes of anaesthetic risk. Describe an animal in class 4 (high risk) and give examples of a procedure
Animals with pre-existing systemic disease or disturbances of a severe nature
Dehydration, shock
Uraemia, pyrexia
Uncompensated cardiac disease
6
There are 5 classes of anaesthetic risk. Describe an animal in class 5 (grave risk) and give examples of a procedure
Life-threatening disease or disturbance
Includes all moribund animals not expected to survive 24 hrs
Severe GDV
Advanced cardiac disease
Severe shock
7
What does a pre-op assessment include?
1) Signalment(age, sex, species, breed, weight)
2) History (previous/ongoing conditions)
3) Physical examination
4) Pre-anaesthetic blood tests
5) further diagnostic tests such as ultrasonography, ECG
8
What is checked during a physical examination?
General body condition
Cardiovascular:
H.R. , pulse, auscultation, mms, CRT
Respiratory:
auscultation, R.R., upper airway conformation
Temperature
Hydration status
Mentation/behaviour (for any CNS problems, and also assess temperament!)
9
What does the RBC count (PCV) analysis test?
oxygen carrying capacity
10
What does the ALT/ALP analysis test?
Liver function
11
What does the urea/creatinine analysis test?
Kidney function
12
What does the glucose analysis test?
Diabetes/stress
13
What does the albumin/TP analysis test?
Low levels are potential anaesthetic risk
