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.
These techniques are classified by the level at which the needle or catheter is inserted for injecting the local anesthetic — interscalene block on the neck for example is considered the second most complete postoperative analgesia, [1] supraclavicular block immediately above the clavicle, infraclavicular block below the clavicle and axillary ...
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 ...
Intravenous regional anesthesia (also called a Bier block): dilute local anesthetic is infused to a limb through a vein with a tourniquet placed to prevent the drug from diffusing out of the limb. Central nerve block : Local anesthetic is injected or infused in or around a portion of the central nervous system (discussed in more detail below in ...
Intravenous regional anesthesia. In 1908, Bier pioneered the use of intravenous regional anesthesia, [2] [3] a technique which is commonly referred to as a "Bier block". [4] This technique is frequently used for operations of brief duration upon the hand, wrist, and forearm.
On August 16, 1898, German surgeon August Bier (1861–1949) performed surgery under spinal anesthesia in Kiel. [12] Following the publication of Bier's experiments in 1899, a controversy developed about whether Bier or Corning performed the first successful spinal anesthetic. [13] [14] There is no doubt that Corning's experiments preceded ...
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.
Local anesthetics vary in their pharmacological properties and they are used in various techniques of local anesthesia such as: Topical anesthesia (surface) - Similar to topical gel numbing before getting injected with Lidocaine. Infiltration; Plexus block; Adverse effects depend on the local anesthetic method and site of administration ...
