A. Horses, small ruminants, camelids
B. Dogs and Cats
C. Pigs
D. Dogs
A. horses, small ruminants, and camelids
Dog under anesthesia before surgery starts. HR, RR and BP WNL. Palpebral reflex and jaw tone are present, eyes are central. Stage of anesthesia?
A. Stage I B. Stage II C. Stage III-1 D. Stage III-2 E. Stage III-3 F. Stage IV
C. Stage III - 1
Horse under anesthesia w/ nystagmus. Which plane of anesthesia is this?
A. 1
B. 2
C. 3
A. 1
Cat premedicated with ketamine+ace+hydromorphone; anesthesia induced w/ propofol; maintenance w/ iso in 100% O2. HR, RR and BP WNL. Palpebral reflex and jaw tone absent, eyes are ventromedial, ETiso=1.5%. Stage?
A. Stage I B. Stage II C. Stage III-1 D. Stage III-2 E. Stage III-3 F. Stage IV
D. Stage III - 2
There may be prolonged and rough recovery from anesthesia when thiopental is administered to greyhounds.
True
What is an anticipated complication of horses under anesthesia
Horses are more prone to muscle damage during anesthesia (they have more muscle) –> Post Anesthetic Myopathy
You are administering fluid therapy to your patient for maintenance under anesthesia. Your patient is 11pounds. How many mL will you give an hour?
A. 10-12.5 mL/Kg/h
B. 22-27.5mL/Kg/h
C. 25-50mL/Kg/h
D. 55-110mL/Kg/h
C. 25 - 50 mL/kg/h
Ok you have the amount, now what is the preferred type of fluid administered during anesthesia?
A. Hetastarch B. LRS C. Norm-R D. P-148 E. 0.9% NaCl
B. LRS
You’re treating a patient with signs of Hypotension due to decreased contractility. Which of the following would you use as perioperative fluid therapy?
A. Dopamine in LRS
B. Vasopressin in Saline
C. Epinephrine in Hetastarch
D. Dobutamine in NaCl
D. Dobutamine in NaCl
When would you use 0.9% NaCl?
- -> Never during anesthesia, no exceptions
- -> Treat septic shock
- -> Cerebral edema
- -> Pyloric obstruction with vomiting
- -> Respiratory acidosis
0.9% NaCl is not used during anesthesia “Except” in patients with “Metabolic Alkalosis” –> Pyloric obstruction with vomiting would create metabolic alkalosis and is therefore your answer
(other situations: Abomasum displacement, horse with small intestinal obstruction)
Which crystalloid would you use in the treatment of your patient which has cerebral edema/head trauma?
- -> LRS
- -> 0.45% NaCl
- -> 0.9% NaCl
- -> 5% NaCl
3% - 7.5% NaCl: (Hypertonic Crystalloids) has an osmotic effect on the brain because of its high tonicity together with it’s ability to effectively remain outside the BBB barrier able to dehydrate the brain tissue –> Decreasing ICP helping your patient with cerebral edema.
Hypertonic solutions are also used to treat other conditions - Pg11 LN / Pg8 PP
True or False- pRBC is a colloid soln and increases oncotic pressure
False- pRBC’s are NOT a colloid soln. and do NOT increase oncotic pressure
True or False - Crystalloids can contribute to osmotic pressure and oncotic pressure
False - Can contribute to “Osmotic” but -> NOT Oncotic pressure…
Which of the following when given in excess can impact blood coagulation associated with a reduction of circulating levels of factor VIII and von Willebrand factor?
A. LRS
B. Oxyglobin
C. Hetastarch
D. Fresh Frozen Plasma
A. Hetastarch
Which of the following peripheral temps (more than 1) correlate w/ core temp during anesthesia?
- -> Mouth
- -> Axilla
- -> Bladder
- -> Skin surface
- -> Rectum
Bladder and Rectal temp accurately reflect core temp during anesthesia
In septic or endotoxemic shock what color mucous membranes would you expect?
- -> Pale
- -> Cyanosis
- -> Pink
- -> Bright Pink
- -> Bright Red
Bright Red <– Severe Vasodilation
what about if your patient dies under anesthesia …. what color would you expect the mucus membranes to be?
They may remain pink long after the animal dies under anesthesia.
Put the animals in order of decreasing mortality rate.
Cat, Dog, Horse, Rabbit
Horses, Rabbit, Cat, Dog»_space;>Human
True or False- Using only inhalant anesthetics is a risk associated with morbidity and mortality
True
