Question | Answer |
---|---|
Duration of Dexmedatomidine | 1 hr |
Expected effects of Dexmedatomidine | sedative & analgesic, profound, long-lasting sedative, calming |
Unwanted effects of Dexmedatomidine | decreases CO, inhibits ADH, respiratory depression, commonly profound bradycardia d.t. intense vasoconstriction, 1st & 2nd degree AV block, vomiting in dogs & cat |
Duration of ace | 4-8 hrs, may last up to 48 hrs in older animals or animals with liver disease |
Expected effects of ace | antiemetic, calming, potential peripheral vasodilation |
Unwanted side effects of ace | SLOW onset of duration; don't use for hypovolemic shock patients |
Duration of Butorphanol | SHORT duration (3/4-1.5 hours) |
Expected effects of Butorphanol | minimal analgesia & sedation, less GI effects, minimal CV compromise |
Unwanted side effects of Butorphanol | respiratory depression, bradycardia, vomiting, use w/ caution on head injuries |
Duration of buprenorphine | slow onset, long duration (4-8 hrs) - if given at high doses |
Expectant effects of buprenorphine | moderate analgesia, LEAST sedative |
Unwanted side effects of buprenorphine | respiratory depression, bradycardia, vomiting, use w/ caution on head injuries |
Duration of Hydromorphone | 3-6 hours |
Expectant effects of Hydromorphone | Analgesia & sedation, 8x more potent than Morphine |
Unwanted side effects of Hydromorphone | respiratory depression, bradycardia, vomiting, use w/ caution on head injuries, panting (dogs) - all opioids |

Unwanted side effects of Propofol | respiratory depression |
Unwanted side effects of Anti-cholinergics | tachyarrhymias - ventricular or supraventricular |
Ketamine/Midazolam | inc. HR, maintains arterial BP, minimal effects on respiration, though apnea can occur |
