A technique for blocking the brachial plexus using a electrostimulator and conventional, non-special plastic cannula with an obtulator consist of conductive metal is described. This cannula is cheaper and more conventional than special plastic-coated needle. Brachial plexus block is useful anesthesia for surgical treatment of fractures, dislocations, skin and muscle injuries of the forearm and hand. ⋯ Therefore the method using an electrostimulator and a special plastic-coated needle for the brachial plexus block was reported in 1962 by Greenblatt. Employing a conventional plastic cannula for intravenous use instead of a special plastic-coated needle reported by Greenblatt. We could attain nerve block completely reliably, safely and easily.
