Some defects are associated with IVRA including tourniquet-related pain and insufficient duration of the anesthesia. The main purpose of the current study was to compare the effects of adding paracetamol or magnesium sulfate to lidocaine in IVRA on pain, venous blood gasses (VBG) and sensory and motor block.Methods: There were 90 patients contributed in the current study. Patients were divided into paracetamol (P), magnesium sulfate (Mg) and control (C) groups, randomly. Severity of the pain, time interval between the injection and onset of the sensory and motor block, duration of the sensory and motor block and the changes of VBG were measured.Results: The onset of the sensory and motor block was reduced significantly in Mg group (p M3 ER -
