Of sedating a cebu dating filipina
Generally, it’s to make the horse more amenable when something nasty or scary is being done to them. There are quite a lot of horses out there that need a sedative before the farrier can trim their feet; and there are others that will allow you to suture up a wound without sedation or even local anaesthetic (not recommended, but occasionally necessary).
It’s important to remember that once sedation has been achieved; increasing the dose WON’T result in deeper sedation, just more side effects. There are two side effects in particular that we as vets watch out for with ACP.
1) Stitching up wounds, to stop the horse wriggling!
2) Tooth rasping, especially when using power rasps and dremels 3) Some surgical operations – for example, many vets prefer to castrate colts under standing sedation, rather than a general anaesthetic.
Although opiates on their own are only very weak sedatives in horses, when combined with other drugs they lead to much deeper and smoother sedation than any other drug on its own.
The drug usually used is butorphanol, which is a synthetic opiate (it’s a mu/kappa agonist/antagonist related to buprenorphine, for anyone interested) that has a fairly good painkilling effect as well as potentiating sedation from other drugs.
