OBJECTIVES An animal model using beagle dog has been established to investigate the postmortem redistribution of lidocaine. MATERIALS AND METHODS 18 dogs were euthanized and injected lidocaine (13 mg/kg) via epidural immediately. An autopsy was performed at 0, 12, 24, 48, 72, 96 hours after drug administration. All animals were stored in supine position at room temperature. For the other grou...

BACKGROUND Topical lidocaine is a common form of anesthesia for a wealth of procedures across a large number of disciplines, including laser treatments. Preparations can be purchased over the counter with no prescription necessary. It is considered a safer and more acceptable form of anesthetic than hypodermic injections; however, there have been reports of fatalities following its application....

Methods This case series identified seventeen patients who received lidocaine over a six month period and recorded demographic data, amount of lidocaine administered, the amount of opioid medication administered before and after lidocaine, preand post-lidocaine pain scores, and any qualitative descriptors of the patient’s pain recorded in the record. Side effects and adverse events were also re...

Background: Lidocaine is a local anesthetic and antiarrhythmic agent. There are reports on accidental and intentional cases of poisoning following injection of lidocaine while rare are the fatal cases realized after oral ingestion of lidocaine. Suicidal poisoning with lidocaine pharmaceutical formulations is rare since no pharmaceutical dosage forms for oral use are available except gels and sp...

The purpose of this study was to develop novel lidocaine microspheres. Microspheres were prepared by the oil-in-water (o/w) emulsion technique using poly(D,L-lactide-co-glycolide acid) (PLGA) for the controlled delivery of lidocaine. The average diameter of lidocaine PLGA microspheres was 2.34±0.3 μm. The poly disperse index was 0.21±0.03, and the zeta potential was +0.34±0.02 mV. The encapsula...

in this paper, the photocatalytic degradation of lidocaine hcl, an anesthetic was investigated inaqueous solution using cuo/zno as a photocatalyst. the degradation was studied under differentconditions including the amount of the photocatalyst, irradiation time, initial concentration of drug,ph of the system, initial concentration, addition of oxidant on the reaction rate and anion presence.the...

It has been reported that lidocaine is toxic to various types of cells. And a recent study has confirmed that lidocaine exerts a demethylation effect and regulates the proliferation of human breast cancer cell lines. To recognize a potential anti-tumor effect of lidocaine, we evaluated the DNA demethylation by lidocaine in human breast cancer lines, MCF-7 and MDA-MB-231 cells, and determined th...

BACKGROUND This study aimed to evaluate the effects of lidocaine treatment on cognitive impairment in aged patients undergoing spine surgery and to explore the underlying mechanism. MATERIAL/METHODS Patients were randomly divided into 2 treatment groups: (1) saline (control) and (2) lidocaine. After induction of anesthesia, the lidocaine group received lidocaine as a bolus of 1 mg/kg over 5 m...

Incubation of whole blood or PMNs in saline with 1O 2 or 1O molar concentrations of lidocaine causes a reversible inhibition of granulocyte adherence. A single bolus dose of lidocaine, 2.5 mg/kg, given intravenously inhibits adherence in rabbits by 55.4% at 5 mm, with return to normal by 1 5 mm after dose. When the bolus dose is followed by an infusion of lidocaine. 0.3 mg/kg/mm, adherence stay...

Lidocaine, as an anesthetic substance, is often used for surface and spinal anesthesia. However, studies have shown that lidocaine may induce transient neurological symptoms and cauda equina syndrome. In the present study the effects of the ginsenoside Rg1 (Rg1) on lidocaine‑induced apoptosis were assessed in Jurkat cells using flow cytometry and terminal deoxynucleotidyl transferase-mediated d...
