Baza lidokainy CAS:137-58-6

Lidokaina, xylocaine, or lignocaine is a common local anesthetic and class-1b antiarrhythmic drug. Lidocaine is used topically to relieve itching, burning, and pain from skin inflammations, injected as a dental anesthetic, or as a local anesthetic for minor surgery.It is on the World Health Organization's List of Essential Medicines, a list of the most important medications needed in a basic healthcare system.

Lidocaine is the most important class-1b antiarrhythmic drug; it is used intravenously for the treatment of ventricular arrhythmias (for acute myocardial infarction, digoxin poisoning, cardioversion, or cardiac catheterization) if amiodarone is not available or contraindicated.

Lidocaine should be given for this indication after defibrillation, CPR, and vasopressors have been initiated. A routine prophylactic administration is no longer recommended for acute cardiac infarction; the overall benefit of this measure is not convincing.

The efficacy profile of lidocaine as a local anesthetic is characterized by a rapid onset of action and intermediate duration of efficacy. Dlatego, lidokaina nadaje się do infiltracji, block, and surface anesthesia. W przypadku znieczulenia podtwardówkowego i zewnątrzoponowego czasami preferowane są substancje dłużej działające, takie jak bupiwakaina.; lidokaina,though, Zaletą jest szybki początek działania.

Relative insensitivity to lidocaine is genetic.In hypokalemic sensory overstimulation, relative insensitivity to lidocaine has been described in people who also have attention deficit hyperactivity disorder.In dental anesthesia, a relative insensitivity to lidocaine can occur for anatomical reasons due to unexpected positions of nerves. Some people with Ehlers-Danlos syndrome are insensitive to lidocaine.

Lidokaina, along with ethanol, ammonia, and acetic acid, has also been proven to be effective in treating jellyfish stings, both numbing the affected area and preventing further nematocyst discharge.
