Recovery from outpatient anaesthesia: a comparison of incremental propofol and propofol-isoflurane.

Propofol was used to induce anaesthesia in 60 patients undergoing minor outpatient gynaecological procedures. Maintenance was with 66% nitrous oxide in oxygen, plus either isoflurane or 10-mg increments of propofol. Recovery was assessed using both clinical and psychomotor criteria and the results compared with those obtained in a non-anaesthetized control group. As far as the two test groups were concerned, initial recovery was more rapid in the incremental propofol group but, by 1 h after surgery, there were no differences between all three groups.
