Richard Burroughs, Evening all. A colleague in Zimbabwe has a 3 month old elephant calf this is walking in circles. He wants to knock the animal out to do X-rays, otoscopic examination and pharyngeal endoscopy. Any suggestions wrt safe combinations to use on an elephant of this age? Thanks Douw Grobler, [04 Apr 2023 at 21:39:42]: 2 mg M99 with a touch of Azaperone should work 100% on that calf Richard. Just by deep IM injection Simone Herzog, [05 Apr 2023 at 13:38:34]: I used Butorphanol in 3 different calves (5d, 5m, 20m ) on its own as analgesic with 0.015mg/kg iv or I'm. It resulted in all 3 cases in sedation deep enough to allow for intended diagnostic procedures. Analgesia lasted for about 6 hours. (Recomm. elephant care for analgesia in Asian elephants) Richard Burroughs, Thanks Douw and Simone
