My vet does not use Ketamine. However, I'm going to add it to my 'Do Not Use' list. The vet staff already thinks I'm nuts because I won't allow them to give them Metacam, steroids, grains, and I feed partially raw.

Ketamine has been around a long time, and most vets are familiar with it's use. It's relatively inexpensive to use, and most vets are aware of it's benefits and risks. Propofol has been around for about 20 years in human anesthesia medicine. I don't know when it was introduced to the veterinary community for anesthesia induction. It is quite a bit more expensive than Ketamine (at least in the O.R. where I work, so I am assuming it must be more expensive in a veterinary practice.)
I prefer to not use Ketamine because it can cause a significant increase of bloodpressure, elevated heart rate and respiratory depression. CRF cats often have elevated blood pressure to begin with, and Cleo also has a heart murmur. Ketamine is also contraindicated in pets with liver disease, and kidney disease. It is metabolized slowly, so it has a prolonged action. It can also cause seizures. I would prefer something much faster acting, much shorter acting, more kidney friendly, and causes so many fewer side effects, such as Propofol. http://www.petplace.com/drug-library...ket/page1.aspx http://cats.about.com/cs/anesthesia/...standing_2.htm |

Because of it's effects on blood pressure and heart rate, Ketamine can also cause heart failure and even instant death in cats with cardiomyopathy. And since there are so many cats out there with undiagnosed heart conditions, like HCM, it's just not a risk I'm willing to take - especially with so many safer options available.

Can I ask what the problem is with Ketamine? Mine have not had surgery (since they were neutered) but I would like to know in case they need something in the future.
I've heard about the Metacam problems and that is on my do not use list, but would like to know about Ketamine if I need to add that. Do most vets use it as first choice? |
