Is lidocaine used as an antiarrhythmic?
Lidocaine is a class Ib antiarrhythmic agent on the Vaughan-Williams classification, and its use is indicated in the management of acute ventricular tachydysrhythmias. It also has roles as an adjuvant analgesic in the management of acute and chronic pain.
Why lidocaine is not used in atrial arrhythmias?
Because lidocaine must be administered parenterally, it is largely restricted to emergency situations and hospital settings. Its use is contraindicated in supraventricular arrhythmias because it is largely ineffective against these arrhythmias and excessive ventricular rates may result.
Can lidocaine cause heart arrhythmia?
Lidocaine-induced ventricular rate increases are common in atrial flutter and fibrillation, particularly in patients who are also receiving quinidine.
What is the effect of lidocaine on arrhythmia?
LIDOCAINE (Xylocaine) has become one of the most frequently used drugs in the treatment of ventricular arrhythmias, particularly those associated with acute myocardial infarction. It has been shown to terminate ventricular tachycardia, and it has been given to suppress multiple ventricular extrasystoles.
What class of antiarrhythmic is lidocaine?
Lidocaine is an IV class IB antiarrhythmic that increases the electrical stimulation threshold of the ventricle, suppressing the automaticity of conduction through the tissue. Although lidocaine may terminate VT successfully, it may increase the overall mortality in peri-infarction VT.
What is the use of lidocaine?
LIDOCAINE (LYE doe kane) is an anesthetic. It causes loss of feeling in the skin and surrounding tissues. It is used to prevent and to treat pain from some procedures. This medicine is also used to treat minor burns, scrapes and insect bites.
Is lidocaine used for ventricular fibrillation?
Lidocaine is a class IB antiarrhythmic drug used in the treatment of ventricular arrhythmias, specifically ventricular tachycardia and ventricular fibrillation. Lidocaine blocks cardiac sodium channels shortening the action potential and is used intravenously only for arrhythmia.
When is lidocaine used for arrhythmias?
Lidocaine is an IV antiarrhythmic agent that has moderate efficacy against ventricular arrhythmias. It is particularly useful in the setting of myocardial infarction or ischemia. It may be used as an alternative to amiodarone in the management of recurrent or shock refractory ventricular fibrillation/tachycardia.
Is lidocaine a Class 1a antiarrhythmic?
Quinidine, disopyramide, procainamide, lidocaine, mexiletine, flecainide, and propafenone are all class I antiarrhythmic drugs (table 1) used for the treatment of various atrial and ventricular arrhythmias.
Is lidocaine used in ACLS?
Lidocaine is now included with amiodarone in the ACLS algorithm for treatment of shock-refractory VF/pVT (Figures 1 and 2). The recommended dose of lidocaine is 1.0 to 1.5 mg/kg IV/IO for the first dose and 0.5 to 0.75 mg/kg IV/IO for a second dose if required.
What contains lidocaine?
Creams and ointments that contain only lidocaine include AneCream, Aspercreme with Lidocaine, BenGay, CidalEaze, Ela-Max, LidaMantle, Lidosense 4, Lidotral, LMX 4, LMX 4 with Tegaderm, LMX 5, MENTHO-CAINE, RectaSmoothe, RectiCare, Solarcaine, SOLUPAK, and Xylocaine.
