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.
In nerve blocks, it is injected around a nerve that supplies the area, or into the spinal canal's epidural space. [5] It is available mixed with a small amount of epinephrine to increase the duration of its action. [5] It typically begins working within 15 minutes and lasts for 2 to 8 hours. [5] [6]
Spinal anaesthesia (or spinal anesthesia), also called spinal block, subarachnoid block, intradural block and intrathecal block, [1] is a form of neuraxial regional anaesthesia involving the injection of a local anaesthetic or opioid into the subarachnoid space, generally through a fine needle, usually 9 cm (3.5 in) long.
The axillary block is also the safest of the four main approaches to the brachial plexus, as it does not risk paresis of the phrenic nerve, nor does it have the potential to cause pneumothorax. [12] In the axilla, the nerves of the brachial plexus and the axillary artery are enclosed together in a fibrous sheath which is a continuation of the ...
The Inferior alveolar nerve anaesthesia or block or IANB (sometimes termed "inferior dental block", or wrongly referred to as the "mandibular block") probably is anesthetized more often than any other nerve in the body. An injection blocks sensation in the inferior alveolar nerve, which runs from the angle of the mandible down the medial aspect ...

In this type of nerve block, a needle inserted between two ribs releases a steroid into the area around the nerve. The exact location of injection depends on the underlying cause of the injury. After three to five days, the steroid begins to relieve pain. Depending on the individual, the pain-relieving effects of the steroid last for days to ...
