DEXAMETHASON ADMINISTRATION IN INTRAVENOUS REGIONAL ANESTHESIA: ITS AFFECT ON POST OPERATIVE PAIN A RANDOMIZED DOUBLE BLINDED CLINICAL TRIAL

Abstract

Introduction. Intravenous regional anesthesia (IVRA) is one of the successful method of anesthesia in relief of pain of surgery. It has a multiple advantages including feasibility, rapidity of recovery, rapid onest, muscular relaxation and controllable onset of anesthesia. But this technique dose not relief postoperative pain. In the previous studies it had been tried to add some drugs to local anesthetic in IVRA for relief postoperative pain.
Methods. One hundred and ten adult patients in class I and II ASA scheduled for elective operation of unilatral upper extrimeties under IVRA, randomly allocated into interventional and control groups. NRA was done with Lidocaine 0.5 percent with or without dexamethason. Postoperative pain was assessed by visual analogue scale.
Results. Addition of dexamethason to local anesthetic in IVRA resulted in better tolleration of turniquate pain and reduced VAS score. Frequency of severe postoperative pain was reduced in case group.
Discussion. It seems that dexamethason usage in local anesthetic in IVRA prevents sever postoperative pain in patients. The results of this study is simillar to the study wich added ketorolac to IVRA solution.
