I had bad experience with pentobarbital. It is very easy to overdose
if you want to anaesthetise your animal well. Yoy get often apnoe and
I guess some kind of lung oedema. I was using ketamine and xylazine
mixture with good results (don't remember doses) for adrenalectomy
after messing with pentobarbital. It was working well and the
anaesthesia was lasting for 20 min.
