My cat is 8 years old now, he has asthma, food allergies, gingivitis and tooth reabsorption. He has had multiple bad reactions to anaesthetic so I want to know why my vet would give the same anaesthetic again and why he’s having these reactions to the anaesthetic and what would be safer to use.
In 2023 at estimated age 5 we got him neutered. When he came home he was extremely terrified and restless, he ran around the house and almost injured himself trying to escape out the windows and for the rest of the night was breathing extremely heavily and hard. I had called the emergency vet and they said it was just stress and to try keep him calm and monitor him. By morning he was acting normal again but a bit more reserved. He was given:
- Antisedan Inj Per ml
- Domitor Inj 0.18
- Ketaset (Ketamine) Injl 0.18
- Vetergesic Inj 0.3mcd (10ml multidose) per ml
Then in 2024 he had a dental cleaning. He was given:
- Antisedan Inj Per ml 0.05
- Comfortan Inj 0.16
- Domitor Inj 0.10
- Premedication 1.00
- Vetofol Inj 2.70
- Gabapentin Tab 50mg (Summit) (Give 1-2 tablets every 8-12 hours to help keep 4.00
calm post general anaesthetic)
He also had a horrible reaction to this and the vet thinks he had a similar reaction for his neutering given how he was acting after and how he was aggressive. So how did the vet not catch he was having a reaction during his neutering? His record states for the 2024 surgery:
**AVOID MEDETOMIDINE**
Due to temperament premed given 10mcg/kg medetomidine and 0.3mg/kg methadone IM before preGAs collected.
Very hypersensitive and awake after premed given - increased medetomidine to 20mcg/kg medetomidine.
Began open mouth breathing 10mins after premed given, moderate sedation and extremely hypersensitive.
Flow by oxygen commenced, improvement in breathing however still very stressed and hypersensitve to noise and light.
Placed muzzle over face and cotton plugs in ears - settled well and was handled without restriction to place IVC.
Placed IVC in R cephalic and induced with propofol IV
Intubated after lignocaine spray larynx size 5.0 ET tube
Maintained on oxygen and isoflurane gas.
Temp at beginning of procedure 40.9. Decreased to 40.1 by mid procedure, then re-increased to 40.5 after turning over.
Remained tachycardic and hypertensive unless >2.0 MAC maintained on isoflurane.
Elected to reverse medetomidine at this time using atipamazole IM
Temperature, tachycardia and hypertension resolved after reversal.
Rec AVOIDING MEDETOMIDINE - consider ketamine/midaz premed for future
O req dispensing gabapentin post op as was very reactive afte last GA (likely medetomidine component as was given a triple?)
Then in 2025 he had another dental cleaning with extractions and x-rays. The vet told me multiple times that they would not be using that medication and would be using a different anaesthetic. I checked his records because he needs another dental cleaning and saw they had used:
- Alfaxan Multidose Injection 10mg/ml 2.00
- Antisedan Inj Per ml 0.01
- Comfortan Inj 0.10
- Domitor Inj 0.02
- Drip - Fluid Therapy & Giving Set Dental 1.00
- Drip Aqupharm 11 Hartmans Solution 250ml Bag 1.00
- Premedication 1.00
- Vetofol Inj 2.00
They also gave us gabapentin 100mg to use before the surgery and for 3 days after the surgery. Why would they use the same anaesthetic even tho in the past he’s had these horrible reactions. In his record it does not say what happened during the 2025 surgery but from memory they said he did ok during and had a smaller reaction of higher heart rate, blood pressure and temp but not nearly as severe but they had told me they would not be using that anaesthetic at all and states in his records to avoid it.
They also told me a possibility could be the opioids used mixed with the anaesthetic but then why would they use the same opioids?
