The pudendal block gets its name because a local anesthetic, such as lidocaine or chloroprocaine, is injected into the pudendal canal where the pudendal nerve is located. The pudendal nerve branches off of the sacral plexus and is both a sensory and motor nerve. [2] The pudendal nerve provides sensation information (i.e. innervates) for the ...
A pudendal nerve block, also known as a saddle nerve block, is a local anesthesia technique used in an obstetric procedure to anesthetize the perineum during labor. [18] In this procedure, an anesthetic agent such as lidocaine is injected through the inner wall of the vagina about the pudendal nerve. [19]
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.
As discussed previously, pudendal nerve block is used as a diagnostic test for pudendal nerve entrapment. If the pain is relieved, this could mean that the origin of the pain is the pudendal nerve. However, pudendal nerve blocks are sometimes used as a long-term treatment, rather than as a one-time diagnostic test.
Illustration of imaging from a CT-guided nerve block. The needle tip has been placed at the top of the pudendal canal to block the pudendal nerve. Diagnostic nerve blocks are very effective for identifying sensory entrapment points. Their strength is that they can directly measure whether a given nerve is contributing pain, or not.
A nerve decompression is a neurosurgical procedure to relieve chronic, direct pressure on a nerve to treat nerve entrapment, a pain syndrome characterized by severe chronic pain and muscle weakness. In this way a nerve decompression targets the underlying pathophysiology of the syndrome and is considered a first-line surgical treatment option ...
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 inferior alveolar nerve block is probably one of the most common methods used by dentist to anaesthetise the mandibular teeth in adults. This technique aims to inject the needle and deposit local anaesthetic close to the nerve before it enters the mandibular foramen, which locates on the medial aspect of the mandibular ramus.
