IIRC sevo is only licensed in dogs.

A heavy sedative dose of medetomidine is more than twice the pre-med dose. I doubt that was the issue.

As the OP has gone, I suspect we won't get any more info, but what size was the tube? Was it checked it was not blocked with mucous? Was a capnograph used?

There's something to be said for tripple combination.....

I think atipamezole and medetomidine were also mentioned? Is it possible that the drugs were confused and the cat received a double dose of medetomidine? I've certainly seen this happen where bottles are the same size and appearance and the only difference is in the colour of the labels (at a glance). But second Clive's comments about sevo - we don't use it, but I've certainly had friends comment about it in cats and small furries.

I've had three similar cases with Sevofluane (I think that was mentioned in the OP, which now seems to have disappeared?), where they seem to go very deep very quickly. One of them the heart stopped, but we managed to revive, and all 3 were eventually OK.

It can be more difficult as a locum; using different agents and equipment , and working with colleagues you're not used too. In my case I was not used to Sevofluare, and in one of the 3 cases I was working with an untrained locum nurse without a permanent staff member.

These events are not good. I've been in the position of turning off the oxygen and turning up the nitrous at the end of an op. As I was a year post anaesthesia certificate, it was not a good moment.

What needs to happen here is for all the staff involved to review the circumstances and the events that led to the adverse event. It's critical that the practice looks at the processes as these are what cause most adverse events. This is different to the "no-blame" culture. Blame might be attributable (as in my case) but it's more likely that something happened (e.g. me answering a question rather than looking at the dials).

The nurse monitoring the anaesthesia controlled everything. It was everything ok intra op. In the end of the surgery the cat couldnt wake up, he became dyspneic and tachicardic, untill total failure

Unlikely to be a " reaction ". What monitoring was used , have you reviewed the anaesthetic monitoring chart. Most likely respiratory depression, respectively arrest then cardiac arrest .
