Depends on what anesthetic you use. For an anesthetic which is really just an extreme pain reliever, they use a nitrous/oxygen which is sometimes called 'Laughing gas'. It is so called because in small doses it would give the patient a sensation of uncontrollable giggling fits.
To put someone to sleep they use the same gas but on a larger scale. The patient breathes it in voluntarily the they use a 'feeding tube' to deliver the gases straight to the lungs where they get immediately distributed to the blood streams.
Sometimes though they would use the liquid version of a general anesthetic first; evoflurane,Isofluruorane and halothane. Then they would use the other anesthetics afterwards.
Nitrogen or nitrous oxide is used in hospitals.
Nitrous Oxide
Yes, typically desflurane, isoflurane, or sevoflurane are used.
Nitrous oxide is a gas used in hospitals for anaesthetics. It has the chemical formula N2O

Nitrous oxide
This is a way too general question considering there are 100's of anaestics. Also, different types. Some more specific info would help.

Gas can be compressed easily.
Mainly pure oxygen is used, but this is often used in conjunction with nitrous, which has some pain- relieving properties and lowers the amount of actual anasthetic used. The drug that keeps the patient under anasthetic is vaporized into the o2/n2 mixture and therefore is breathed in by the patient.
