Dexamethasone has been recognized as an antiemetic agent after surgeries, and the combination of dexamethasone and tramadol remained stable in solution up to 5 days. In addition, i.v. basal infusion of tramadol is a certified technique in postoperative pain management. We purposed that combined administration of dexamethasone and tramadol adjunct to i.v. morphine is an effective way in treating postoperative pain.
