80-100

Question 9

Mean

Answer 9

100-110

Question 10

Hypotension tx

Answer 10

1. Fluids
2. decrease inhalent
3. give drugs
   
   • dopamine: dopa, beta, alpha receptors
   • dobutamine: dopa, beta receptors
   • ephedrine: alpha and beta adrenergic agonist; may also inc release of norepi

Question 11

Hypertension tx

Answer 11

1. Inc inhalent
2. phentolamine: non-selective alpha agonist
3. nitroprusside: peripheral vasodilator

Question 12

HCM

Answer 12

• Don’t
  
  • give glyco
  • give ketamine
• Reduced HR = inc volume in ventricles
  
  • Treat intra-op hypotension wtih alpha 1 agonist instead of beta
    
    • ephedrine….?
    • higher dose dopamine….?

Question 13

Rough recovery

Answer 13

• Give analgesic
• Continued roughness can Ace

Question 14

Equine

guaifenesin/diazepam

Answer 14

• More profound sedation
• Improve muscle relaxation
• Better induction quality

*Guaifenesin: expectorant, muscle relaxant

*Ketamin intraop if horses move

Question 15

Dobutamine

Answer 15

• Beta 1 (positive inotrope)
  
  • inc HR/CO/MAP/RBF
• Beta 2 (bronchiol relaxation)
• Post op myopathy….?

Question 16

Alpha 2 agonists

Answer 16

• Drugs
  
  • zylazine
  • detomidine
  • medetomidine
  • romifidine
• Standing sedation
• Effects
  
  • Decr CO (inc resistance, decr HR)
  • Bradycardia (incr vagal tone, decr sympathetic tone, 2nd degree block common)

Question 17

Over dose of lidocaine

Answer 17

Seizures, then hypotension

Question 18

Morphine and Meperidine

Answer 18

• Cause histamine release if given too fast
• Meperidine only opioid that will cause incr HR
• Morphine causes hypotension
  
  • give fluids or vasoconstrictor => ephedrine

Question 19

Ephedrine

Answer 19

• alpha agonist
• beta agonist

Question 20

All horses get

Answer 20

• Direct BP measurement
  
  • dorsal metatarsal a
  • lateral metacarpal a

Question 21

More horsie things

Answer 21

1. Romifidine prolongs recovery
2. mortality in horses
   
   • arrest
   • recovery fractures
3. phenylephrine => for nasal edema
4. 90% pulse ox = 60 PaO2
5. 100% pulse ox = 120-600 PaO2
6. 70-75% pusle ox = 40 PaO2

Question 22

Phenylephrine

Answer 22

• sympathimimetic
• primarily alpha receptors
• nasal decongestant

Question 23

B-1 receptors

B-2 receptors

A-1 receptors

A-2 receptors

Answer 23

• B-1 = positive inotrope
• B-2 = bronchiole dilation
• A-1 = vasoconstriction
• A-2 = think drugs I guess, sedation

Question 24

Isoproterenol

Answer 24

• Beta 1 and beta 2 agonist
• treatment for sick sinus syndrome
• give CRI for 3rd degree AV block
