Magnetic resonance image of lumbar spine Nerve block of the cervical spine. Lumbar sympathetic neurolysis is typically used on patients with ischemic rest pain, generally associated with nonreconstructable arterial occlusive disease. Although the disease is the basis for this type of neurolysis, other diseases such as peripheral neuralgia or ...
The upper two lumbar ganglia (L1 and L2) of the sympathetic chain also give rise to the lumbar splanchnic nerves. Splanchnic nerves are paired visceral nerves carrying preganglionic sympathetic and general visceral afferent fibers. The lumbar splanchnic nerves travel through the lumbar sympathetic ganglion but do not synapse there.
Endoscopic thoracic sympathectomy (ETS) is a surgical procedure in which a portion of the sympathetic nerve trunk in the thoracic region is destroyed. [1] [2] ETS is used to treat excessive sweating in certain parts of the body (focal hyperhidrosis), facial flushing, Raynaud's disease and reflex sympathetic dystrophy.
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.
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.
Intravenous regional anesthesia (IVRA) or Bier's block anesthesia is an anesthetic technique on the body's extremities where a local anesthetic is injected intravenously and isolated from circulation in a target area.
Lumbar splanchnic nerves: L1–2: Inferior mesenteric ganglia, ganglia of intermesenteric and hypogastric plexuses: Sacral splanchnic nerves: sacral part of sympathetic trunk: inferior hypogastric plexus and ganglia to the pelvic viscera: Pelvic splanchnic nerves: parasympathetic: S2–S4
Lumbar sympathetic block: A procedure performed to manage pain originating from the lower back, buttocks or legs. [39] Common indications: complex regional pain syndrome (CRPS)/regional sympathetic dystrophy (RDS), post-herpetic neuralgia, neuropathy. Pudendal nerve block: A procedure performed to manage chronic pelvic pain.
