This block is particularly useful in providing anesthesia and postoperative analgesia for surgery to the clavicle, shoulder, and arm. Advantages of this block include rapid blockade of the shoulder region, and relatively easily palpable anatomical landmarks. Disadvantages of this block include inadequate anesthesia in the distribution of the ...
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.
Since the suprascapular nerve provides sensory information to 70% of the joint capsule, blocking this nerve can help with post-operative shoulder pain. A nerve stimulator, ultrasound device, or a needle insertion that is 1 cm above the midpoint of the scapular spine can quickly block the suprascapular nerve. [24]
A temporary nerve block with an anesthetic is usually performed before surgery to confirm the diagnosis of neuropathic pain. [1] Risks include numbness, neuroma, and complications due to lack of innervation.
Diagnostic nerve blocks can confirm the clinical diagnosis for chronic pain as well as identify the entrapment site. [5] A diagnostic block is like an inverted palpation in the sense that palpation will cause a sensory nerve to send a signal (action potential) and a block will prevent a sensory nerve from sending a signal. By blocking nerve ...
A supraclavicular nerve block is useful when performing surgery on the shoulder, anaesthetising a large area of skin. [5] The supraclavicular nerves are vulnerable during surgery on the clavicle, and must be identified early on in surgeries to reduce the risk of nerve injury and neuroma. [6]

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 ...
