although, i was watching 'trauma' last night and the anaesthetist said a patient will tend to wake up in the same state they went to sleep in. so when they get a patient who was in a violent fracas and put under as a result of injuries, they were angry when they went to sleep and tend to wake up combative.
but, as she said, 'there's nowhere you can't get with a 16 gauge needle' .
all my experiences with GA, however, have been after i've been given a nice pre-op and am all happy and floating and trippy when i went out.
