Background: Traumatic neuroma is a common sequela of peripheral nerve injury or amputation, which often leads to severe neuropathic pain. The present study investigated the effect of local lidocaine administration on preventing the formation of traumatic neuroma.
Methods: Forty-eight male Sprague-Dawley rats were randomly assigned to two groups. The lidocaine group underwent sciatic nerve transection, followed by an injection of lidocaine (0.5%) around the proximal of a severed sciatic nerve under ultrasound-guidance 2-7 days after neurectomy. In the control group, rats received an injection of saline following neurectomy. The autotomy score, mechanical allodynia, thermal hyperalgesia, histological assessment, expression of neuroma, and pain-related markers were detected.
Results: Lidocaine treatment reduced the autotomy score and attenuated mechanical allodynia and thermal hyperalgesia. The mRNA expression of α-SMA, NGF, TNF-α, and IL-1β all significantly decreased in the lidocaine group in comparison to those in the saline control group. The histological results showed nerve fibers, demyelination, and collagen hyperplasia in the proximal nerve stump in the saline control group, which were significantly inhibited in the lidocaine group.
Conclusions: The present study demonstrated that local lidocaine administration could inhibit the formation of painful neuroma due to traumatic nerve injury.

Fusidic Acid and Lidocaine-Loaded Electrospun Nanofibers as a Dressing for Accelerated Healing of Infected Wounds.

Introduction: Wound treatment is a significant health burden in any healthcare system, which requires proper management to minimize pain and prevent bacterial infections that can complicate the wound healing process.
Rationale: There is a need to develop innovative therapies to accelerate wound healing cost-effectively. Herein, two polymer-based nanofibrous systems were developed using poly-lactic-co-glycolic-acid (PLGA) and polyvinylpyrrolidone (PVP) loaded with a combination of an antibiotic (Fusidic acid, FA) and a local anesthetic (Lidocaine, LDC) via electrospinning technique for an expedited healing process by preventing bacterial infections while reducing the pain sensation.

Background: This review aimed to assess if the use of dexmedetomidine as an additive to local anesthetics promotes greater safety and efficacy than local anesthetics alone in dental procedures.
Material And Methods: the systematic review was structured according to the PICO strategy and adhered to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) checklist. Studies were included based on the eligibility criteria, and data from the included studies were collected by one author.
Lidocaine Enhanced Antitumor Efficacy and Relieved Chemotherapy-Induced Hyperalgesia in Mice with Metastatic Gastric Cancer.

Department of Anaesthesiology, West China Hospital, Sichuan University, Chengdu 610041, China.
With the widespread use of lidocaine for pain control in cancer therapy, its antitumor activity has attracted considerable attention in recent years. This paper provides a simple strategy of combining lidocaine with chemotherapy drugs for cancer therapy, aiming to relieve chemotherapy-induced pain and achieve stronger antitumor efficacy. However, there is still a lack of substantial pre-clinical evidence for the efficacy and related mechanisms of such combinations, obstructing their potential clinical application.

Objectives: The aim of this study was to review the most effective topical anesthetic methods for reducing pain/discomfort prior to dental local anesthetic needle puncture for dental procedures in children and adolescents.
Methods: A scoping review was conducted. Individual search strategies were developed for each of the bibliographic databases (Cochrane, Embase, LILACS, LIVIVO, Pubmed, Scopus, PsyINFO, Web of Science), and in the gray literature (Google Scholar, Open Gray), comprehensively, without restrictions on language, publication data, or level of socioeconomic development of the country in which the study was conducted.
