Bupivacaine is contraindicated in patients with known hypersensitivity reactions to bupivacaine or amino-amide anesthetics. It is also contraindicated in obstetrical paracervical blocks and intravenous regional anaesthesia because of potential risk of tourniquet failure and systemic absorption of the drug and subsequent cardiac arrest. The 0.75 ...
The drug typically starts taking effect within 15 minutes and can last up to 16 hours depending on factors such as site of administration and dosage. [1] Levobupivacaine was designed, in the late 1970s, to be a safer and more effective alternative to bupivacaine, which had been associated with a higher risk of cardiotoxicity.
A mixture of 1 part 2% lidocaine with 3 parts 0.5% bupivacaine provides 0.5% lidocaine and 0.375% bupivacaine. This has the advantages of immediate anesthesia with lidocaine during injection to minimize injection pain while providing a longer duration of action with a lowered concentration of bupivacaine.

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 ...
Medical intervention Epidural administration A freshly inserted lumbar epidural catheter. The site has been prepared with tincture of iodine, and the dressing has not yet been applied. Depth markings may be seen along the shaft of the catheter. ICD-9-CM 03.90 MeSH D000767 OPS-301 code 8-910 [edit on Wikidata] Epidural administration (from Ancient Greek ἐπί, "upon" + dura mater) is a method ...
Examples of these factors include the patients individual response to the drug, vascularity and pH of tissues at the site of drug administration, the type of injection administered etc. [3] Hence figures citing the duration of action of local anaesthetics is an approximation, as extreme variations may occur among patients.
Usually a single-shot dose is administrered through a fine needle, alternatively continuous spinal anaesthesia through a intrathecal catheter can be performed. [2] It is a safe and effective form of anesthesia usually performed by anesthesiologists and CRNAs that can be used as an alternative to general anesthesia commonly in surgeries ...
4-Aminopyridine is also used under the trade name Avitrol as 0.5% or 1% in bird control bait. It causes convulsions and, infrequently, death, depending on dosage. [18] The manufacturer says the proper dose should cause epileptic-like convulsions which cause the poisoned birds to emit distress calls resulting in the flock leaving the site; if the dose was sub-lethal, the birds will recover ...
