Surgery #6 went well, and was slightly less involved (still under general, still intubated etc, but the surgery itself involved fewer stitches and incisions) than expected. It was a different anesthesia than we've used in the past, which Rob was comfortable with, but I wish Rob had been home with me to talk me through some of the recovery.
With all previous surgeries, Oscar recovered mentally and physically at the same rate, which was hard to see. With this, on the new anesthetic (I can't remember the name but I can find out if anyone's curious) he recovered VERY quickly physically.
He actually woke up faster than the doctor seemed to expect (I suspect it was because the doctor asked me back to see the surgery site while he was still under, and I believe Oscar heard/smelled me and woke up to be with me; the timing matches that). He was only slightly tipsy in the beginning, was able to trot to the car and get up inside without assistance within about twenty minutes of waking up. On the car ride home I stopped to get a movie from Red Box (side note: don't rent "Robin Hood Ghost of Sherwood" Just trust me) and when I was out of the car Oscar jumped from the backseat into the front seat without problem. He got out of the car and inside the house without difficulty either. It was like he hadn't been anesthetized at all, physically.
Mentally, it was scary. He was blank. He wasn't aggressive or anything, he just wasn't him. He looked confused for about ten hours. He wouldn't sit or lie down, didn't seem to know what I meant when I invited him to snuggle or sit with me. I watched him starting to fall asleep on his feet several times. He didn't have any spark to him, and it just wasn't him. Quite honestly, I was starting to suspect brain damage (not that I'd heard anything, this just didn't seem like Oscar was inside that body anymore).
He's a little more normal today, though he's clearly uncomfortable. He's taking Tramodol as needed, and that seems to help. Rob assures me that everything that happened yesterday was normal for that anesthesia, that in his experience animals either wake up more quickly (though I still feel like Oscar popped up faster than expected) or more slowly than with other drugs, but that it was very safe and he was acting in no way that concerned Rob, so I think we're okay. It was just very disturbing!
