Hi,
I have lots of experience with spays/neuters. Couple of thoughts here. First, if you have any voice in the procedure, laser works much better for spays. There is some debate on this issue in the vet community mostly cost comparison between laser and conventional procedures as laser is more expensive. Based on our years of experience with spays, we insist on laser. There is much less blood loss since the laser with seal the blood vessels. The much cleaner incision heals much faster without complications. Our vets do not use external sutures. We have self dissolving internal sutures with a final close with surgical glue. We have never had any problem with a laser spay.
Next is the importance of pain meds. They are essential. Metacam is one of the more common analgesics prescribed. It is a NSAID...similar to our Tylenol. In my non-professional opinion, it is totally insufficient pain control. I generally use either Buprenorphine (Buprenex) or Tramadol. Either of these drugs can be used in conjunction with Metacam. We usually do at least 3 days of Buprenorphine for spays. Some vets will tell you they get a one shot of pain meds that will work long term....not true. Some vets are cautious about sending Buprenorphine home since it is a controlled drug...but it is the best pain med available for a rabbit. Tramadol is also quite effective and very cost efficient. Unfortunately few vets are familiar with it's use in rabbits. It comes only in a tablet so it does need to be compounded into a suspension. But it is a great drug for moderate to severe pain.
Best wishes.
