In this video peripheral nerve block using peripheral nerve stimulator. The local anesthetic syringe is connected to the flexible tubing of the needle and the tubing is flushed with local anesthetic solution or saline which acts like a stylet and prevents tissue entering the needle. The point of needle insertion is determined by anatomical landmarks. It is important to make sure the circuit is complete as soon as the needle is inserted. The machine may have a flashing light or audible beep or some other mechanism to indicate that the circuit is complete. The needle approach and direction should be anatomically correct to maximize the chances of correct localization and minimizing complications. The needle is then advanced in the direction towards the nerve until distinct muscle contractions occur in the innervated area.
