We know enough about them to use them safely, but most anaesthetic drugs are somewhere on the spectrum from "not fully understood" to "a complete mystery". Science knows how anaesthesia works in the same sense that I know how a car works - I can push the pedals and turn the wheels with sufficient proficiency to get to the grocery store in one piece, but I'll be damned if I can explain what's happening under the hood.
Anesthesia usually includes drugs with distinct, separate actions, like an analgesic (to block pain receptors), muscle relaxants (so patients can be moved/organs accessed), CNS depressants (to prevent unexpected spasms disturbing the surgeon), coma-inductors (so patients don’t chat with the staff and freak them out after practicing on cadavers for years), and amnesia-inductors (because surgery is kind of gross).
