Hi,
Any idea what pain meds were given PRE-op? Someold school vets do not use pre-op analgesics. Post-op, Metacam is better than nothing but I always insist on a narcotic aspect after any surgery. Buprenorphine is by far the best but Tramadol is an acceptable alternative. Metacam will help with any inflammation. I also agree with your vet....keep him confined and cover him. That is standard procedure when we have a recovering surgery (same for emergency triage).
Stress could be a part of the issue here along with pain. Buprenorphine will help sedate.....or a little injection of valium is what we use to calm admissions to our rescue. Valium is a wonderful thing.
As far as the question regarding Iso or Sevo as the anesthesia....that should be totally irrelevent if administered by a skilled vet. I have sedated baby cottontails (as small as 35g), domestic rabbits, squirrels, opossums,degus, dogs, cats, birds....pretty much all of them. Iso has traditionally been the gas of choice for rabbits. Personally, I like Sevo much better and most of the top end vets are transitioning over to this inhalent. The effects are much quicker....and more important, the rebound time is much faster without excessive drowsiness. One of my vets (this particular vet is one of the best in the country with exotics and avian and is a teaching vet) first introduced us to Sevo a couple of years ago. Our first experience was with a dental surgery....and we were impressed and have continued to be impressed with this anesthesia with each use. I have no problem with Iso, Sevo or injectables...but if I havea choice when using a gas, it will be Sevo. In the real world, horror stories regarding anesthesia are usually related more to the skills (or lack)of the doctor than a problem with the drug. While there is risk in any medical procedure, I no longer "sweat bullets" during surgeries.
And justa note from personal experiences....usually late in the second day into early tht fourth day after surgery is the most uncomfortable.
