The Median Effective Concentration (EC) of Epidural Ropivacaine With Different Doses of Oxycodone During Limb Surgery in Elderly Patients.

In this study, we determined the median effective concentration (EC) of epidural ropivacaine required for great saphenous vein surgery in elderly patients in order to describe its pharmacodynamic interaction with oxycodone.
