Anesthetic nerve block catheter

Patent Pending Regional anesthesia may be performed as a single shot or with a continuous catheter through which medication is given over a prolonged period, e.g. continuous peripheral nerve block (CPNB). Regional anesthesia can be provided by injecting local anesthetics directly into the veins of an arm (provided the venous flow is impeded by a tourniquet.) This is called intravenous regional techniques (Bier block).
