10

What opioid cardiopulmonary effects may occur?

Bradycardia
Possible hypotension
Respiratory depression is dose dependent
Apnea possible at higher doses

11

What opioid GI effects may occur?

Salivation
Nausea
Vomiting in species that can
Defecation

12

What opioid CNS effects may occur?

Depression – dogs – excellent sedation
Excitement – esp. cats & horses
Analgesia – before, during, or after surgery
Behavior changes
Decreased body temp – esp. dogs – panting – resets temp regulating center
Decreased urine production
Excessive sweating – horses
Cough suppression – Butorphenol, hydrocodone
Miosis in dogs and pigs; mydriasis in cats and horses
Increased response to sensory stimuli
May or may not lose consciousness
Responsive to auditory stimuli
Many defecate/some vomit/flatulence
Sedation-analgesia; ataxia &/or recumbency
Decreased ventilation/apnea may occur
Bradycardia – premed. To prevent
Analgesia
Behavioral abnormalities – after procedure
Some breeds i.e. Dobermans

13

Define neuroleptanalgesia.

A state of CNS depression and analgesia produced by the combination of a tranquilizer or sedative and an analgesic drug
Useful in dogs, cats, horses, pigs

14

What is an example of Neuroleptanalgesia drug cocktail?

Fentanyl + Droperidol
Useful for short operative procedures

15

What effect do NSAIDS have?

Decrease inflammation/produce analgesia
Not on the scale of opioids
