Joel Alves, [13 Sep 2022 at 12:24:58]: Afternoon all. Has anyone used any battery operated cautery products that they could recommend? Was keen on looking at options beyond good old clamping and potassium permanganate for rhino ear notching. Obviously would need to be cost effective and not a super pricey tool for something like that. Just interested. Alex Lewis, [13 Sep 2022 at 12:31:10]: Glow plug work great and super simple and cheap Erik Verrynne, [13 Sep 2022 at 12:31:59]: Hi Joel. I used a battery operated one but found it not very useful. The veins and associated increase in BP when using butorphanol means you cause more burn damage than actually stopping the bleeding. Clamping with artery forceps (and good old clean Kalahari sand ) works more effectively Joel Alves, [13 Sep 2022 at 12:33:41]: Thanks for that. It is a bit much of a “re-inventing” the wheel concept so was just putting out feelers for interest! Henry Labuschagne, [13 Sep 2022 at 14:35:11]: If you want to use heat I am happy with the mini gas soldering iron to cauterise bleeders. I still prefer KMnO4 for ear-notching. You can also use Dr du Toits Staaldruppels...
