简要总结
The purpose of study was to find out the minimum effective value of ropivacaine 0.5% in ultrasound guided supraclavicular nerve block. As before introduction of USG, peripheral nerve block techniques were blinded and basicly relied upon anatomic landmarks. Ultrasound method has dramatically decreased the adverse effects associated with blind techniques e.g. pneumothorax, vascular or neural injuries. But, still the minimum effective dose in this technique is not established, hence we tried to discover it.
