Lidocaine Description:
 
1. Lidocaine, 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.
 
2. It is on the World Health Organizations List of Essential Medicines, a list of the most important medications needed in a basic healthcare system.
 
3. 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.
 
4. 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.

Lidocaine Usage Fields:
 
1. The efficacy profile of lidocaine as a local anesthetic is characterized by a rapid onset of action and intermediate duration of efficacy. Therefore, lidocaine is suitable for infiltration, block, and surface anesthesia. Longer-acting substances such as bupivacaine are sometimes given preference for subdural and epidural anesthesias; lidocaine, though, has the advantage of a rapid onset of action.
 
2. Epinephrine (adrenaline) vasoconstricts arteries, reducing bleeding and also delays the resorption of
 lidocaine, almost doubling the duration of anaesthesia. For surface anesthesia, several available
formulations can be used e.g. for endoscopies, before intubations, etc. Buffering the pH of lidocaine
makes local freezing less painful.[2] Lidocaine drops can be used on the eyes for short ophthalmic
procedures.
 
3. 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.
 
4. Lidocaine, 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.
