Unfortunately little Bunny passed away this morning.
I gave her the pain medication and fed her, allowing it to take effect before I changed her bandages, hoping to minimize pain and stress. She was eating very well, but still making occasional groans. I waited about an hour before I attempted to change her bandages. I set her in my lap as I always do and unwrapped her bandages. She didn't seem extremely painful or stressed. I cleaned her very gently, just sprayed the cleaner on and dabbed it off. I took a picture as I've been trying to record it so I have a better idea of how well/fast she's improving. Point being, I was not touching her, she was just laying there when she started to screech. She was opening her mouth wide and squealing repeatedly. I tried to comfort her, thinking she was stressed/in pain? I put her down on her blankets immediately and she wasn't really responsive. She continued to gasp, though the screeching had stopped. I tried to feel for a heartbeat and felt nothing. She was laying on her side no moving, and then the gasping stopped. She had a few spaced out gasps... no heartbeat. This all happened in about 45 seconds, though it seemed like forever.
I talked to the vet later on, though I was too upset to go into details, but she told me some of her bloodwork was back and that her kidney and liver values were normal, she was anemic, her WBC was a little low.. but nothing seemed extremely off. The E.Cuniculi titer is pending. Her urine was well concentrated and normal... I just don't know what happened.
I have been going through my mind trying to imagine what happened. She had some mucousy stool last night and this morning.. and I read about a disease that can cause this, but I don't know if that was really what the issue was as she did not have diarrhea and was eating extremely well. I wondered about blood clots due to her paralysis in the back legs. Yesterday one of her feet was swollen due to the way she laid on it the night before, so I wondered if she ended up cutting off some circulation in her legs causing a blood clot that then moved to her heart? I really don't know if that's even possible, just one of the many things I wondered about. I know that Buprenex can cause respiratory depression, but she had no trouble breathing until the screeching and gasping started... I also wondered if the E.Cuniculi itself caused damage to part of her brain leading to an issue with a major organ...
I just wish I had an answer... I hope it wasn't something I could have prevented.
