    Two common general anaesthetic techniques were compared to evaluate the time taken for the patient's mental efficiency to recover sufficiently for him to be escorted home after inguinal herniorrhaphy. Recovery in performance efficiency to at least 60% of the patient's own maximum is suggested as a criterion for discharge, and this needs a stay in hospital of seven to nine hours.
