Comparison of anesthesia with a morphine-lidocaine-ketamine infusion or a morphine-lidocaine epidural on time to extubation in dogs

Administration of MLK at the doses reported in this study did not prolong the time to extubation in comparison with a morphine-lidocaine epidural nerve block. The results indicate that concern over prolonging the time to extubation is not a reason to avoid the administration of MLK.
