This study was performed to assess and compare the effects on motor and sensorial blockade and side effects of muscle relaxant addition to lidocaine during regional intravenous anaesthesia. The parameters related with exsanguination of the upper extremity and tourniquet usage were also assessed. Fifty one patients scheduled for elective hand surgery were included into the study and randomly assigned to 3 groups. Standard regional intravenous anaesthesia technique with 0.5% lidocaine (3 mg/kg) was used for all patients. Atracurium (50 μg/kg) or vecuronium (7 μg/kg) were added in to lidocaine solution for group 2 and group 3, respectively. Motor and sensorial blockade measurements were done after injection of local anaesthetic solution. Blood pressure, heart rate, symptoms of local anaesthetic toxicity were also recorded. Quality of anaesthesia and muscle relaxation, and bleeding from surgical area were scored by the surgeon at the end of operation. We concluded that: a) there is no clinical advantage of muscle relaxant addition to the local anaesthetic solution doses used in this study; b) lidocaine in dose and concentration used in this study is capable of producing anaesthesia within 15 minutes; c) the technique used in this study is able to produce sufficient exsanguination and prevents local anaesthetic toxicity except hypertensive patients; d) tourniquents with single cuff are sufficient for operations shorter than 45 minutes.
