Bupivacaine, marketed under the brand name Marcaine among others, is a medication used to decrease sensation in a specific small area. [5] In nerve blocks, it is injected around a nerve that supplies the area, or into the spinal canal's epidural space. [5] It is available mixed with a small amount of epinephrine to increase the duration of its ...
Lidocaine is one of the most commonly used local anaesthetics in dentistry. It can be administered in multiple ways, most often as a nerve block or infiltration, depending on the type of treatment carried out and the area of the mouth worked on. [10] For surface anaesthesia, several formulations can be used for endoscopies, before intubations ...
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.
Research also shows that lidocaine can help ease nerve pain in people with conditions like diabetes-related nerve damage, complex regional pain syndrome, cancer, and pain after breast surgery.
Bupivacaine (Marcaine) is the local anaesthetic most commonly used, although lidocaine , tetracaine, procaine, ropivacaine, levobupivicaine, prilocaine, or cinchocaine may also be used. Commonly opioids are added to improve the block and provide post-operative pain relief, examples include morphine, fentanyl, diamorphine, and buprenorphine.
[1] [2] Compared to bupivacaine, levobupivacaine is associated with less vasodilation and has a longer duration of action. It is approximately 13 per cent less potent (by molarity) than racemic bupivacaine and has a longer motor block onset time. [3] Ropivacaine is, next to levobupivacaine, another less cardiotoxic alternative to bupivacaine. [4]
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 ...
The Inferior alveolar nerve anaesthesia or block or IANB (sometimes termed "inferior dental block", or wrongly referred to as the "mandibular block") probably is anesthetized more often than any other nerve in the body. An injection blocks sensation in the inferior alveolar nerve, which runs from the angle of the mandible down the medial aspect ...
