Background and Objective: The aim of this research was to compare the anesthetic effect of epidural lidocaine and tramadol and their combination in rabbit as a model for further research on methods of epidural anesthesia in humans. Materials and Methods: This experimental study was conducted on 12 New Zealand white rabbits that were divided into 3 groups of 4. In the first experimental group...
Background: Various drugs are used as adjuvants to improve the quality of supraclavicular block. Objective: This study aimed to investigate the effect of adding dexmedetomidine to lidocaine on the characteristics of supraclavicular block in upper limb surgeries. Methods: This double-blind controlled clinical trial was conducted on patients undergoing upper extremity fracture surgery under a ...
The inappropriate activation, positioning, and recruitment of leukocytes are implicated in the pathogenesis of multiple organ failure in sepsis. Although the local anesthetic lidocaine modulates inflammatory processes, the effects of lidocaine in sepsis are still unknown. This double-blinded, prospective, randomized clinical trial was conducted to investigate the effect of lidocaine on leukocyt...
ObjectiveTo evaluate the total toxic dose of lidocaine and serum lidocaine concentrations resulting in clinical signs of toxicity in chickens. DesignExperimental study AnimalsEight healthy, female, 55-week-old chickens (Lohman breed) weighing 1.45 ± 0.17 kg (mean ± SD) ProcedureA loading dose of 2% lidocaine (4 mg/kg) was administered IV, followed by a constant-rate infusion at a dose of 8 mg/k...
We studied the effective spread of lidocaine to inactivate neural tissue in the frontal cortex of the rhesus monkey. Injections of 2% lidocaine at 4 microl/min were made while units were recorded 1 or 2 mm away. To inactivate units 1 mm away from the injection site 100% of the time, 7 microl of lidocaine had to be injected. To inactivate units 2 mm away from the injection site 100% of the time,...
Lidocaine, a common local anesthetic drug, has anti-inflammatory effects. It has demonstrated a protective effect in mice from septic peritonitis. However, it is unknown whether lidocaine has effects on high mobility group box 1 (HMGB1), a key mediator of inflammation. In this study, we investigated the effect of lidocaine treatment on serum HMGB1 level and HMGB1 expression in liver, lungs, kid...
TWIK-related K+ channel TREK1, a background leak K+ channel, has been strongly implicated as the target of several general and local anesthetics. Here, using the whole-cell and single-channel patch-clamp technique, we investigated the effect of lidocaine, a local anesthetic, on the human (h)TREK1 channel heterologously expressed in human embryonic kidney 293 cells by an adenoviral-mediated expr...
AIMS To explore whether lidocaine has the synergistic effect with pingyangmycin (PYM) in the venous malformations (VMs) treatment. METHODS The mouse spleen was chosen as a VM model and injected with different concentration of lidocaine or PYM or jointly treated with lidocaine and PYM. After 2, 5, 8 or 14 days, the mouse spleen tissues were acquired for hematoxylin-eosin (HE) staining, transmi...
The modulated receptor hypothesis states that sodium channels have a specific receptor for antiarrhythmic drugs. Therefore, two agents that block sodium channels by binding to this receptor are expected to compete for occupancy. Glycylxylidide (GX) is a deethylated metabolite of lidocaine that accumulates in patients on lidocaine therapy. In single, voltage-clamped cardiocytes, GX, like lidocai...
BACKGROUND Arterial catheterization is painful and is associated with patient stress and anxiety. Analgesia is usually provided by subcutaneous injection of local anaesthetic. An alternative is topical anaesthesia, such as Rapydan which is a novel topical anaesthetic patch containing 70 mg each of lidocaine and tetracaine. We therefore tested the hypothesis that Rapydan patch analgesia is non-i...
