BACKGROUND: The local anesthetic lidocaine can affect intra- and extra-cellular signaling pathways in both neuronal and non-neuronal cells, resulting in long-term modulation of biological functions, including cell growth and death. Indeed, lidocaine was shown to induce necrosis and apoptosis in vitro. While several studies have suggested that lidocaine-induced apoptosis is mitochondrial pathway-dependent, it remains unclear whether reactive oxygen species (ROS) are involved in this process and whether the observed cell death can be prevented by antioxidant treatment...

: Patients and practitioners rate the insertion of a nasogastric tube as one of the most painful and distressing procedures performed. Research supports using lidocaine and a nasal vasoconstrictor to significantly decrease patient discomfort. The recommended medications were not being used routinely in a large urban emergency department. METHODS: We identified departmental barriers using a nurse survey and physician interviews. We educated the nursing and physician staff about the comfort medications for nasogastric tube insertion recommended in the literature...

INTRODUCTION: In the treatment of patients with symptomatic irreversible pulpitis, endodontic debridement is a predictable method to relieve pain. However, there are clinical situations in which emergency care cannot be provided immediately. An unexplored treatment option in these cases may be the use of a long-acting anesthetic to reduce pain in untreated irreversible pulpitis. Some medical studies have shown potential for infiltrations of liposomal bupivacaine (Exparel; Pacira Pharmaceuticals, San Diego, CA) to prolong pain relief and reduce opioid use postoperatively...

In this work, we first describe the population variability in hepatic drug metabolism using cryopreserved hepatocytes from 5 different donors cultured in a perfused 3D human liver microphysiological system and then show how the resulting data can be integrated with a modeling and simulation framework to accomplish in vitro-in vivo translation. For each donor, metabolic depletion profiles of 6 compounds (phenacetin, diclofenac, lidocaine, ibuprofen, propranolol and prednisolone) were measured, along with metabolite formation, mRNA levels of 90 metabolism-related genes, and markers of functional viability (LDH release, albumin and urea production)...

BACKGROUND: Ventricular tachycardia (VT) and ventricular fibrillation are the causes of approximately 300,000 deaths per year in the United States. VT is classified based on hemodynamic status and appearance. Stable, monomorphic VT treatment is controversial. OBJECTIVE: Our aim was to provide emergency physicians with an evidence-based review of the medical management of stable, monomorphic VT. DISCUSSION: Stable, monomorphic VT is part of a larger class of ventricular dysrhythmias defined by a rate of at least 120 beats/min with QRS > 120 ms without regularly occurring P:QRS association...

A 12-day-old boy presented with duskiness 4 h after circumcision with local anesthesia: infiltration with lidocaine (6 mL 1 %) and topical EMLA cream (2.5 % lidocaine/2.5 % prilocaine). He had no respiratory distress, but a strikingly dark skin. A blood sample showed dark, chocolate brown blood with a raised methemoglobin of 49.8 % (normal <1.5 %) and a lactate of 10 mmol/L. A diagnosis of methemoglobinemia was made. The patient was treated with oxygen administration, but methemoglobin concentration was still 45 % 1 h later...

Dental pain management is one of the most critical aspects of modern dentistry which might affect patient's quality of life. Several methods are suggested to provide a painless situation for patients. Desensitization of the oral site using topical anesthetics is one of those methods. The improvements of topical anesthetic agents are probably one of the most important advances in dental science in the past 100 years. Most of them are safe and can be applied on oral mucosa with minimal irritation and allergic reactions...

OBJECTIVE: Intranasal (IN) midazolam is a commonly prescribed medication for pediatric sedation and anxiolysis. One of its most frequently-encountered adverse effects is discomfort with administration. While it has been proposed that premedicating with lidocaine reduces this undesirable consequence, this combination has not been thoroughly researched. The objective of our study was to assess whether topical lidocaine lessens the discomfort associated with IN midazolam administration. METHODS: This was a double-blinded, randomized, placebo-controlled trial performed in an urban, academic pediatric emergency department...

A local anesthetic, lidocaine, is known to affect cutaneous blood flow when injected into the skin. However, it is unknown if dermal lymphatic function can also be affected. Therefore, we characterized lymphatic function in response to administration of lidocaine with and without epinephrine. Non-invasive near-infrared fluorescence imaging (NIRFI) with intradermal injection of indocyanine green (ICG) was used to characterize the lymphatic "pumping" function in mice after subcutaneous injection of 2 % lidocaine with and without 1:100,000 epinephrine or saline...

INTRODUCTION: Greater occipital nerve blocks (GONB) have been used for headache but their benefit may be short. Ready et al performed intrathecal injections on rabbits and reported neurologic/histologic changes that required concentrations of at least 8%. Our study tests the hypothesis that the neurolytic effects of GONB with 10% lidocaine can prolong relief. METHODS: After an approval from Henry Ford Hospital Institutional Review Board, a chart review was performed for patients who had GONB with 10% lidocaine...
