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.
Amide-linked local anesthetic agents, such as lidocaine and bupivacaine, can become "trapped" in their ionized forms on the fetal side of the placenta, so their net transfer across the placenta is increased. An ester-linked local anesthetic agent, such as 2-chloroprocaine, is rapidly metabolized, and placental transfer is limited.
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 ...
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 ...
This is a list of local anesthetic agents. Not all of these drugs are still used in clinical practice and in research. Not all of these drugs are still used in clinical practice and in research. Some are primarily of historical interest.
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.
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 ...
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.
