My beautiful Arista left us yesterday. She went in Tuesday for dental work, she seemed to be still drowsy from the anesthesia , I gave her pain meds ( buprenorphine) which seemed to have a horrible effect on her. I'm afraid the dose was too much?, she couldn't stand on her feet,would just fall over. She would meow like she was stressed, her breathing was slow, she wouldn't eat or drink. Thursday I took her to the vet,they said she was dehydrated, and body temp was too low, they just wanted to hook her up to IV so I left her to get help. An hour later I got a call, she vomited blood all over, and had to be intibated. Her heart rate went low. And she had a heart attack. How did this happen?! My heart is broken!!!... She went in for a broken tooth to be pulled. And passed from a heart attack?!, pre bloodwork was done. I was told the procedure was safe for her. Why would her body temp drop and she vomit blood? Could this be over dose related?! Can anyone offer me insight? My happy 10yr old girl who would great me when I woke up in the am, and when I got home from work is now gone. What went wrong?!
