It doesn’t matter if the bird is big or small: it is always excited when it visits the veterinarian! In order that avoid too much stress and fear, we use a very mild gas-anaesthesia. The bird breathes in a mixture of gas and oxygen and sleeps within a matter of seconds. After that he is completely relaxed and ready for everything.
So the veterinarian can take care of smaller issues like beak-grinding, without having the bird freeze of fear. Even bigger surgeries can be executed without pain. It doesn’t matter whether it’s a endoscopic evaluation of the internal organs, the treatment of wounds or simply the removal of an ingrown leg band.
After the examination the gas supply is stopped. The bird completely breathes out the gas (it is hardly metabolised in the body) and the bird comes back to normal after a few minutes. Shortly after he is sitting on his perch again – and luckily doesn’t remember anything.
