Comparison of recovery times of isoflurane and enflurane as a sole anesthetic agent for outpatient oral surgery.

Patients' abilities to complete the Trieger modification of the Bender Motor Gestalt Test as an indicator of recovery time were compared following outpatient general anesthesia, using either enflurane or isoflurane on 100 patients who had their third molars removed. The time required for patients who received enflurane to satisfactorily complete the test averaged 32.7 minutes, compared with 34.6 minutes for patients who received isoflurane. Statistical analysis indicated that there was no significant difference in recovery time in this particular setting between enflurane and isoflurane.
