<unk> , is anesthesia or (anaesthesia) affecting only a large part of the body, such as a limb.<unk>  anaesthetic techniques can be devided in central and peripheral techniques. The central techniques include so called neuroaxial blocks epidural anaesthesia, spinal anaesthesia, the peripheral techniques can be further devided in plexus blocks like e.g. the brachial plexus blocks, and single nerve blocks.<unk>  may be performed as a single shot or with a continuous catheter through which medication is given over a prolonged period of time, e.g continuous peripheral nerve block. Last but not least,<unk>  can be provided by injecting local anesthetics directly into the veins of an arm (provided the venous flow is impeded by a tourniquette.) This is called intravenous<unk>  techniques (Bier block).<unk>  generally involves the introduction of local anaesthetics to block the nerve supply to a specific part of the body, such as a limb, so patients cannot feel pain.
