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]
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.
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 particular, endoscopic surgery gave much better access to the pudendal nerve as well as the sciatic nerve, and allowed the possibility of decompressing the sacral plexus. [ 18 ] [ 16 ] [ 30 ] The use of image-guided diagnostic nerve blocks provided better capabilities to identify the entrapped nerve as well as the site of entrapment, leading ...
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.
Many local anesthetics fall into two general chemical classes, amino esters (top) and amino amides (bottom). A local anesthetic (LA) is a medication that causes absence of all sensation (including pain) in a specific body part without loss of consciousness, [1] providing local anesthesia, as opposed to a general anesthetic, which eliminates all sensation in the entire body and causes ...
Nerve blocks aimed at the pudendal nerve, superior hypogastric plexus and ganglion of impar have shown to be effective for treating certain types of pelvic pain that do not respond to conservative treatment. [17] Neuromodulation has been explored as a potential treatment option for some time.
