Q
(Small Animal Emergencies: Triage and Patient Stabilisation)
Explain how to perform a triage exam
A
- Stable vs. immediate care (CPA/Shock)
- Based on vital signs- AirwayBreathingCirculation
- Includes brief history (presenting complaint), CPR code status and brief focused physical exam
- Traffic light system Red: Critical Unstable Amber: Urgent/potentially unstable Green: Stable
2
Q
Explain how to perform a primary survey and concept of ABCDE
A
- Goal of a primary summary is to identify and stabalise life threatening problems
- ABCDE stands for AirwayBreathingCirculationDemnorEntire body
3
Q
Explain the difference between a primary and secondary survey
A
In a primary survey, it’s quick, whereas in a secondary survey, you are doing a full clinical examination, body weight, detailed history, and giving the client an estimation of the visit. In this secondary survey, you want to fully understand the patient’s condition and develop a comprehensive diagnosis and treatment plan.
4
Q
Describe common emergency stabilisation measures and evaluate their suitability in an individualpatient
A
5
Q
Describe options for vascular access in the emergency patient
A
- IV should be obtained asap in all critically ill patients for fluids and drugs.
- In patients unable to breathe this may need to be delayed to allow for stabiliation in O2 therapy so options include
- Peripheral venous catheter – cephalic/saphenous
- Central venous catheter- jugular
- PICC- peripherally inserted central catheters
- Intraosseous catheter- prone to infection
- Venous cutdown
6
Q
Describe an emergency database

- Venous blood gas and electrolytes
7

8
Q
Identify different types of shock

- (overlap of different types of shock)
9
Q
Recognise the major indications for fluid therapy and identify clinical cases where fluid therapy may be required
A
The compensatory mechanisms in shock lead to dehydration, volume loss (hypovolemia or blood loss) and 3rd space loss so need fluid therapy to restore circulation and perfusion
10
Q
T/F Fluid is a goal directed therapy
A
True - It is a goal directed therapy
11
Q
What is the fluid rate for dogs?
A
Dogs: 10-20ml/kg IV
12
Q
What is the fluid rate for cats?
A
Cats: 5-10 ml/kg IV
13
Q
What route would you use when treating a patient with fluids?
A
- venous access
- intraosseous access - good in puppies or kittens as difficult to get access
14
Q
What are the two types of fluid you can use?
A
- hypertonic crystalloids shift fluids into the intravascular space, increasing vascular volume rapidly. Has anti-inflam effects and reduces ICP
- colloids are larger molecules that do not cross the vascular endothelium. They have a high Colloid osmotic pressure, which expands and maintains intravascular volume. For shock, a smaller volume than crystaloids is required. They have controversial benefits.
15
Q
What are the different types of drugs that help treat shock?
A
- Vasopressors
- Intropes
- Vitamins can treat oxidative stress.
- steroids
16
Q
What does a Vasopressors do? What can you treat with them?
A
They cause vasoconstriction and reduce the intravascular space optimising volaemia. Could treat septic and distributive shock.
17
Q
What do Intropes do? What can you use them to treat?
A
They decrease systolic function of the heart. Can use to treat septic shock.
18
Q
Explain how monitoring of clinical signs, physiological and laboratory data assist in the diagnosis and treatment of shock
A
It is really important as it gives you an indication of the severity of the shock the patient is suffering from. You should monitor HR, RR, MM colour, CRT, Mentation, Pulses, and extremities (temp).
19
Q
Discuss common complications which may occur as a result of fluid therapy
A
- when treating haemorrhagic shock, an excess of fluid will exacerbate bleeding
- when treating obstructive shock, there is a risk of hypervolaemia after correction.
