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.
Other treatments of superior cluneal nerve dysfunction include both minimally invasive interventions and surgical options. Minimally invasive treatments include nerve blocks, neuroablation, and neuromodulation. [5] Efficacy of these interventions are still being studied and no clear evidence to show long term benefits in larger studies.
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 vasospastic disorders can receive lumbar sympathetic neurolysis for pain ...
The risk of temporary or permanent nerve damage varies between different locations and types of nerve blocks. [13] There is risk of accidental damage to local blood vessels during injection of the local anesthetic solution. This is referred to as haematoma and could result in pain, trismus, swelling and/or discolouration of the region. The ...
Spinal anaesthesia is the technique of choice for Caesarean section as it avoids a general anaesthetic and the risk of failed intubation (which is probably a lot lower than the widely quoted 1 in 250 in pregnant women [3]). It also means the mother is conscious and the partner is able to be present at the birth of the child.
Neuraxial blockade is local anaesthesia placed around the nerves of the central nervous system, such as spinal anaesthesia, caudal anaesthesia, epidural anaesthesia, and combined spinal and epidural anaesthesia. [1] [2] The technique is used in surgery, obstetrics, and for postoperative and chronic pain relief. [3]
The brachial plexus is formed by the ventral rami of C5-C6-C7-C8-T1, occasionally with small contributions by C4 and T2.There are multiple approaches to blockade of the brachial plexus, beginning proximally with the interscalene block and continuing distally with the supraclavicular, infraclavicular, and axillary blocks.
The risk of complications is decreased when proper aseptic technique is followed, and by the use of the imaging guidance. These complications include an epidural abscess due to infection, temporary increased pain, puncture of the sack containing spinal fluid, excess bleeding, nerve damage, leakage of local anesthetic into the spinal canal, and ...
