[07:35, 04/06/2022] HO Reuter: Thanks Douw and team for sharing your experience and knowledge with us here in Namibia! I was very impressed with HH dosages on white rhino in spite of longer induction time compared to other regimes we use. Hilti saw with those blades really works well. [08:09, 04/06/2022] Pierre Nel: Is it the 1,5mg M99 + 10mg medetomidine + 8 mg midazolam? [09:29, 04/06/2022] Andre Uys: I think you can push the medetomidine dose to 12-15 mg. [10:42, 04/06/2022] Peter Rogers: What is the feeling about not having azaperone in the dart for regulating opioid induced high blood pressure ? [4 /6/2022] Andre Uys: I always use it. [10:46, 04/06/2022] Douw Grobler: It was the first time that I really been expose to these dosages of Hendrik Hansen’s and I must say it was really good to see and to test. We did 10 animals with the HH regime and none of them required any extra drugs (butorphanol; M5050; etc) after they were immobilised. On average adult cows we used 2 mg M99 plus 10 mg medetomidine plus 20 mg azaperone. Adding 1500 iu of Hyalase made a 2 to 3 min difference in faster downtimes. Hendrik will add more, as he does numerous rhino procedures keeping them down for as long as 3 hours at a time. Heart rate was very stable in all between 55 and 70. Saturated O2 levels were very impressive with lowest values around 70% and averaging in the 80% plus region. Reversal was with yohimbine/atipamezole mix at 1 ml per 2 mg medetomidine and 50 mg naltrexone. The quality and completeness of reversals were very good in my opinion. Hendrik, thanks so much for your great work and even more thanks for your willingness to share and contribute!! [10:48, 04/06/2022] Peter Rogers: What was the average induction time please ? [10:49, 04/06/2022] Douw Grobler: Hi Pete. With Hyalase added, it was between 6 and 8 minutes. Hendrik will give more info. André Uys has also done quite a few. [11:07, 04/06/2022] Andre Uys: Hi Pete. With Hyalase added to the combination, they usually standing by 7 mins, without Hyalase at about 12 mins. The less you stimulate them, the quicker they stand. I have done several cows now with 2 mg etorphine and 12 mg medetomidine and bulls with 2 mg etorphine and 15 medetomidine. I am very happy with the results. Reversal according to Hendrik Hansen’s combination, and takes some getting used to the down time.
