Blood pressure

Question 1

What should MAP be (minimum)?

> 65-70

Question 2

How do alpha-2 agonists affect blood pressure?

Answer 2

Vasoconstriction -> increased resistance –> higher BP

Good if concerned about hypotension

Question 3

How does ACP affect blood pressure?

Answer 3

Vasodilation –> less resistance –> lower BP

Question 4

What should you do if blood pressure drops intraoperatively due to the animal being too deep?

Answer 4

Decrease isoflurane

Question 5

What should you do if blood pressure drops intraoperatively due to the animal being hypovolaemic?

Answer 5

Give fluids (colloid and crystalloid)

Question 6

What should you do if blood pressure drops intraoperatively, but the animal is not too deep and you suspect the animal is normovolaemic?

Answer 6

Give dobutamine
(Positive inotrope - increased contractility)

Question 7

In a worst case scenario and blood pressure drops very low, what emergency drug can you give?

Answer 7

Adrenaline

Causes major vasoconstriction - rapid rise in HR and BP
