A 16-year-old-girl with a past medical history of lidocaine anaphylaxis requested an allergy test to find a local anesthetic (LA) agent with no adverse allergic reactions for her ingrown toenail treatment. A skin prick test (SPT) and intradermal test were administered using lidocaine, procaine, bupivacaine, mepivacaine and ropivacaine. All LA agents used in the SPT showed negative result. An in...

Lidocaine has proved to be an effective antiarrhythmic agent in the management of ventricular arrhythmias subsequent to acute myocardial infarction. Lidocaine's short duration of action and its propensity for producing central nervous system (CNS) stimulation suggest that a safer and more effective therapeutic agent, based on a modification of the lidocaine structure, might be found. The quater...

The effects of quinidine and lidocaine on the maximum upstroke velocity (Vmax) of the ventricular myocardial action potential were compared with the effects predicted by a model over a wide range of driving rates, rhythm disturbances and holding potentials. These rate-, rhythm- and voltage-dependent effects were accurately predicted by the proposed model. The model was also able to predict seve...

The antiarrhythmic action of lidocaine has been attributed solely to its direct electrophysiological effects on the heart. However, lidocaine is particularly effective in treating ventricular arrhythmias associated with increased sympathetic activity, e.g., in myocardial infarction and digitalis toxicity. We tested the hypothesis that lidocaine administered intravenously depressed cardiac sympa...

BACKGROUND Mutations in the cardiac sodium channel gene (SCN5A) can cause one variant of the congenital long-QT syndrome. The effects of some of these mutations on the alpha-subunit channel properties can be blocked by type Ib antiarrhythmic drugs. Recently, we have described a new SCN5A mutation (D1790G) that affects the channel properties in a manner suggesting that sodium blockers of the Ib ...

conclusions lidocaine-meperidine-diltiazem gel provides significantly better pain control than lidocaine-diltiazem gel and lidocaine gel alone during transrectal ultrasound guided prostate biopsy and probe insertion. this mixture gel is safe, easy to administer and well accepted by patients. results the mean of visual analog pain scale was 4.5 in group a, 3.5 in group b, and 2.0 in group c duri...

BACKGROUND This study was conducted to compare low concentration-high volume intravenous regional anesthesia (IVRA) method with local anesthetic method in upper extremity surgery in terms of efficiency and adverse effects. MATERIAL AND METHODS Thirty-nine patients were divided into 2 groups; the first group received a 2% concentration of 12-15 mL lidocaine (Group 1) and the second group recei...

BACKGROUND This meta-analysis aimed to assess the efficiency and safety of intravenous infusion of lidocaine for pain management after laparoscopic cholecystectomy (LC). METHODS A systematic search was performed in PubMed (August 1966-2017), Medline (August 1966-2017), Embase (August 1980-2017), ScienceDirect (August 1985-2017), and the Cochrane Library. Only randomized controlled trials (RCT...

OBJECTIVES To evaluate the anaesthetic properties and tolerance of articaine versus lidocaine at equal vasoconstrictor concentration. STUDY DESIGN A total of 96 male and female patients who underwent surgical treatment of the lower third molar participated. Patients were randomly assigned to articaine hydrochloride with epinephrine 1:100,000 and lidocaine hydrochloride with epinephrine 1:100,...

Lidocaine is a commonly used antiarrhythmic drug that causes use-dependent blockade of sodium channels in vitro and reduces conduction velocity in vitro and in vivo. According to the modulated receptor hypothesis of antiarrhythmic drug action, lidocaine has a low affinity for rested sodium channels but a high affinity for open and inactivated channels. In the present experiments, we characteriz...
