For many years, retrobulbar and peribulbar anesthesia were the standard for cataract surgery; however, many serious adverse effects have been reported (1, 2). With the introduction of modern phacoemulsification cataract surgery, topical anesthesia without retrobulbar or periocular injections has become a well-established, minimally invasive technique (3). The addition of intracameral lidocaine ...

Lidocaine unmasks silent symptoms and eases neuropathic pain in multiple sclerosis patients; however, the effects of lidocaine in neuromyelitis optica have never been reported. We describe the case of a 59-year-old Japanese woman with neuromyelitis optica spectrum disorder who developed optic neuritis 1 day after intravenous lidocaine injection for treating allodynia. Her symptom seemed to resu...

Aim. Regional analgesia has been introduced as better analgesic technique compared to using systemic analgesic agents, and it may decrease the adverse effects of them and increase the degree of satisfaction. Several additives have been suggested to enhance analgesic effect of local anesthetic agents such as opioids and steroids. We designed this randomized double-blind controlled study to compa...

PURPOSE Three identical single-dose, randomized, double-blind, parallel-group, active-controlled multicenter studies were conducted to compare the safety and efficacy of articaine HCl (4% with epinephrine 1:100,000) to that of lidocaine HCl (2% with epinephrine 1:100,000) in patients aged 4 years to 79 years, with subgroup analysis on subjects 4 to < 13 years. METHODS Fifty subjects under the...

Prilocaine and lidocaine are classified as amide-type local anesthetics for which serious adverse effects include methemoglobinemia. Although the hydrolyzed metabolites of prilocaine (o-toluidine) and lidocaine (2,6-xylidine) have been suspected to induce methemoglobinemia, the metabolic enzymes that are involved remain uncharacterized. In the present study, we aimed to identify the human enzym...

the quality of subarachnoid block can be improved by adding opioids to the local anesthetics. we compared the analgesic effects of different doses of intrathecal sufentanil added to lidocaine %5 for elective cesarean section. this study was a prospective, randomized, double-blind, controlled trial. 90 pregnant women with asa class i-ii, scheduled for elective cesarean section under spinal anest...

Due to unpleasant nature and physiological consequences of postoperative pain, search of safe and effective modalities for its management has remained a subject of interest to clinical researchers. Analgesic action of lidocaine infusion in patients with chronic neuropathic pain is well known but its place in relieving postoperative pain is yet to be established. The study aimed to assess the ef...

BACKGROUND This is an update of the review on "Lidocaine for pain relief in burn injured patients" first published in Issue 3, 2007, and first updated in 2012. Pain is a major issue for people with many different types of wounds, in particular those people with burn injuries. Prompt, aggressive use of opioid analgesics such as morphine has been suggested as critical to avert the cycle of pain a...

BACKGROUND Axonal transport plays a critical role in supplying materials for a variety of neuronal functions such as morphogenetic plasticity, synaptic transmission, and cell survival. In the current study, the authors investigated the effects of the analgesic agent lidocaine on axonal transport in neurites of cultured mouse dorsal root ganglion neurons. In relation to their effects, the effect...

BACKGROUND General anesthetics induce neuronal apoptosis in the immature brain. Regional anesthesia using local anesthetics can be an alternative to general anesthesia. Therefore, this study investigated the possible effect of lidocaine on neuronal apoptosis. METHODS Fifty-one 7-day-old C57BL6 mice were allocated into control (group C), lidocaine (group L), lidocaine plus midazolam (group LM)...
