Local anesthetics (LAs) are widely used in anesthesiology, ophthalmology, and otolaryngology as well as for treatment of chronic and oncological pain. However, anesthetics can cause adverse effects up to lethal ones. In this work, we cited reviews on chromatographic and spectroscopic methods of local anesthetics determination published earlier, and the main purpose was to review the possibilities and advantages of voltammetric methods used for the LAs determination. The electrochemical behavior, mechanism of LAs transformation on the various working electrodes and analytical parameters of voltammetric methods used for their determination were reviewed in the work. Vast majority of these methods were developed for the most widely used anesthetics in medicine like benzocaine, lidocaine and procaine. Special attention was paid to possible mechanisms of electrochemical oxidation and in some cases reduction of LAs or their derivatives. Voltammetry is used for the determination of LAs in pharmaceutical formulations and in biological fluids. The analytical characteristics in terms of sensitivity, selectivity, reproducibility also were discussed in the article.

Background/importance: Local anesthetic (LA) mixtures are used in peripheral nerve blocks (PNB) to improve onset, though study results remain conflicting.
Objective: This systematic review and meta-analysis compared the efficacy outcomes of long-acting LA to their mixture with shorter-acting LA in ultrasound-guided PNB. The primary outcome was sensory block onset.

Background: The peri-operative period may create a biological environment conducive to cancer cell survival and dissemination. Microscopic residual tumours (micrometastases) can be dislodged even with excellent surgical technique. At the same time, the stress response from surgery can temporarily impair immune function and activate inflammatory processes, increasing the risk of tumour proliferation.

Aims/objectives: This systematic review aimed to evaluate the effectiveness of auxiliary aids-Transcutaneous Electrical Nerve Stimulation (TENS), vibrotactile devices, and Low-Level Laser Therapy (LLLT) in reducing pain and anxiety during dental local anesthesia in pediatric patients.
Methods: The review followed PRISMA guidelines, employing a comprehensive search strategy across multiple databases (PubMed, Cochrane, EBSCO, LILACS, Google Scholar, and Embase) from 2014 to July 2024. Eligibility criteria were based on the PICOS framework, focusing on randomized clinical trials and clinical studies involving pediatric patients undergoing dental procedures with local anesthesia.

The effect of epidural infusion of dexmedetomidine on haemodynamics is unclear. This study aimed to explore the effects of epidural or intravenous infusion of dexmedetomidine on haemodynamics during lower extremity varicose veins surgery (saphenectomy) under epidural anaesthesia. Ninety patients were randomly allocated to three groups: ED group (epidural: 0.

Background: Mixed exhaled air has been widely used to determine exhaled propofol concentrations with online analyzers, but changes in dead space proportions may lead to inaccurate assessments of critical drug concentration data. This study proposes a method to correct propofol concentration in mixed air by estimating pulmonary dead space through reconstructing volumetric capnography (Vcap) from time-CO and time-volume curves, validated with vacuum ultraviolet time-of-flight mass spectrometry (VUV-TOF MS).
Methods: Existing monitoring parameters, including time-volume and time-CO curves, were used to determine Vcap.
