Nerve block or regional nerve blockade is any deliberate interruption of signals traveling along a nerve, often for the purpose of pain relief. Local anesthetic nerve block (sometimes referred to as simply "nerve block") is a short-term block, usually lasting hours or days, involving the injection of an anesthetic, a corticosteroid, and other agents onto or near a nerve.
Cryoneurolysis, also referred to as cryoanalgesia, is a medical procedure that temporarily blocks nerve conduction along peripheral nerve pathways. The procedure, which inserts a small probe to freeze the target nerve, can facilitate complete regeneration of the structure and function of the affected nerve.
Local anesthetics can block almost every nerve between the peripheral nerve endings and the central nervous system. The most peripheral technique is topical anesthesia to the skin or other body surface. Small and large peripheral nerves can be anesthetized individually (peripheral nerve block) or in anatomic nerve bundles (plexus anesthesia).
ARROW ® UltraQuik™ Peripheral Nerve Block Needles Receive FDA 510(k) Clearance LIMERICK, Pa.--(BUSINESS WIRE)-- Teleflex Incorporated (NYS: TFX) today announced that the ARROW UltraQuik ...
Injection close to the point of elicitation of such a paresthesia may result in a good block. [4] A peripheral nerve stimulator connected to an appropriate needle allows emission of electric current from the needle tip. When the needle tip is close to or contacts a motor nerve, characteristic contraction of the innervated muscle may be elicited ...

Peripheral nerve blocks use drugs targeted at peripheral nerves to anesthetize an isolated part of the body, such as an entire limb. Neuraxial blockade, mainly epidural and spinal anesthesia, can be performed in the region of the central nervous system itself, suppressing all incoming sensation from nerves supplying the area of the block.
Consequently, knowledge of these anatomical regions as well as peripheral nerve anatomy is an essential component to planning successful diagnostic blocks. [5] Ultrasound is a common form of image-guidance to place the needle properly, but it faces limitations visualizing small and deep nerves. [ 7 ]
