OBJECTIVES: This study aims to assess intrathecal mepivacaine for euthanasia in anesthetized horses and compare it to a traditional euthanasia method using a single intravenous injection of pentobarbital in sedated horses. ANIMALS: Client-owned horses and horses requiring euthanasia due to involvement in concurrent research projects were used. Horses were randomly assigned to 1 of 2 groups: intrathecal mepivacaine after anesthesia or intravenous pentobarbital after sedation...

BACKGROUND: Currently, one of the most discouraging aspects for many patients undergoing dental procedures is the administration of local anaesthesia. Therefore, there is a constant search for new techniques to avoid the invasive and painful nature of the injection. This study aimed to compare the clinical efficacy of local anaesthetics with articaine 4% or mepivacaine 2% (both with epinephrine 1:100.000), using different anaesthetic techniques to perform germectomy of lower third molars and to assess patients' feelings and pain during surgery...

INTRODUCTION: This study evaluated the effect of bupivacaine versus mepivacaine spinal anesthesia and preoperative adductor canal block (ACB) on recovery, length of stay, pain, and complications of same-day discharge total knee arthroplasty (TKA) at a free-standing ambulatory surgery center. METHODS: We performed a retrospective review of patients who underwent TKA between March 2018 and September 2019. The patients were grouped based on the neuraxial anesthetic regimen: bupivacaine with ACB, bupivacaine without ACB, and mepivacaine without ACB...

BACKGROUND: Plantar warts are benign, epidermal neoformations, viral, and easily transmitted. Although 30% of these warts disappear spontaneously, the American Association of Dermatology recommends treatment if they cause pain or bleeding. OBJECTIVES: The aim of this study was to determine the efficacy of Dermojet® infiltration using a solution composed of equal parts of 0.9% saline and 2% mepivacaine in the treatment of plantar warts, and to identify the type of necrosis achieved at 7-10 days after the infiltration (M1 sample) and at 15-17 days (M2 sample)...

Surgical castration of piglets is generally recognized as a painful procedure, but there is currently no gold standard for the assessment of pain behavior in piglets. However, pain assessment is essential for evaluating the effectiveness of local anesthetics. In this study, we investigated the efficacy of four local anesthetics in terms of pain relief during and after surgical castration in three sequential study parts. To do so, we filmed 178 piglets before the applied procedures, after injection of the local anesthetic, and up to 24 h after castration (five observation times in total) in an observation arena and compared their behavior before and after castration and between treatments and control groups...

Background: Many dentists use articaine as their choice of local anesthetic agent. However, the use of articaine is limited to inferior alveolar nerve blocks (IANBs), and literature data are scarce concerning its perception and choice among various dental practitioners. Aim:  The aim of the present study was to assess the extent of articaine use as a local anesthetic in dentistry, its perception basis, and the consistency of evidence of the efficacy and safety of articaine in recent practice...

BACKGROUND: Local anesthesia is essential for pain control in dentistry. The authors assessed the comparative effect of local anesthetics on acute dental pain after tooth extraction and in patients with symptomatic irreversible pulpitis. TYPES OF STUDIES REVIEWED: The authors searched MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, and the US Clinical Trials registry through November 21, 2020. The authors included randomized controlled trials (RCTs) comparing long- vs short-acting injectable anesthetics to reduce pain after tooth extraction (systematic review 1) and evaluated the effect of topical anesthetics in patients with symptomatic pulpitis (systematic review 2)...

OBJECTIVE: To determine the effect of concurrent versus delayed treatment with corticosteroid on equine articular tissues also treated with local anesthetic in vitro in the presence of inflammatory mediators. STUDY DESIGN: Controlled laboratory study. ANIMALS: Five geldings, one mare (aged 3-18 years). METHODS: From each horse, 24 synovial and 12 osteochondral explants were cultured in a 12-well plate (2 wells/group, 2 synovial and 1 osteochondral explant/well, total 216 explants in the study)...

PURPOSE: The purpose of this systematic review is to evaluate the current literature on the use of image-guided corticosteroid injections in the treatment of patients with knee and hip OA. EVIDENCE ACQUISITION: We conducted a comprehensive literature search through June 30, 2022. Publication type, study design, imaging guidance modality, osteoarthritis severity, number of injections, steroid type and dose, anesthetic type and dose, the total number of patients, follow-up intervals, and measured outcomes were extracted from the included studies...

OBJECTIVE: To determine the synovial fluid (SF) concentrations of lidocaine and mepivacaine after intra-articular injection with clinically relevant doses to the distal interphalangeal (DIP), metacarpophalangeal (MCP), middle carpal (MC), and tarsocrural (TC) joint at two different time points after injection in order to be able to compare concentrations with previously established concentrations associated with cytotoxicity and antimicrobial activity. PROCEDURES: In the first of two experiments, 20 joints (5 MC, 5 MCP, 10 DIP joints) of five horses under general anesthesia were injected with clinically referenced doses of 2% lidocaine...

Mepivacaine, an amide-type local anesthetic drug widely used in regional anesthesia, was studied by some aspects such as electrochemical behavior, mechanism illumination, and analytical applications by cyclic voltammetry (CV) and different pulse voltammetry (DPV) methods. In this study, a novel, fast, simple, portable, and the inexpensive electrochemical sensor was developed for the determination of mepivacaine. This study was carried out by mepivacaine anodic direction detection for the first time. The modified sensor was fabricated with silver nanoparticles (AgNP) and multiwalled carbon nanotubes paste electrode (MWCNTPE) by using the drop-dry method...

Pelizaeus-Merzbacher disease (PMD) is a genetic leukodystrophy, which is a progressive and degenerative central nervous system abnormality caused by dysmyelination. Because the incidence of PMD is extremely low, only a few case reports have been published regarding its anesthetic management. In particular, epidural anesthesia has only been reported in one case of general anesthesia combined with caudal anesthesia. We performed general anesthesia combined with epidural anesthesia for the soft-tissue release surgery for bilateral hip subluxation in a six-year-old male patient diagnosed with PMD...

To evaluate pain responses to intratesticular and subscrotal injection of three local anaesthetics and their efficacy during castration a randomized controlled study was conducted. In groups of 20 piglets, procaine (2%), lidocaine (2%), or mepivacaine (2%) were administered subscrotal and intratesticularly in two different dosages: 0.5 mL of the original substances or the maximum recommended dosage according to body weight diluted with isotonic saline to a volume of 0.3 mL per each injection site. Two placebo groups received the equivalent volume of isotonic saline...

BACKGROUND: Intractable chronic pain, as well as motor, sensory, and autonomic neuropathy, significantly reduces the quality of life of brachial plexus avulsion (BPA) patients. We report the successful application of cervical selective nerve root injection (CSNRI) in a patient with BPA. CASE PRESENTATION: A 40-year-old man had been diagnosed with complete left BPA due to a motorcycle accident and underwent intercostal nerve transplantation at the age of 18 years and had been experiencing pain ever since...

The objective of this study was to investigate the electroencephalographic reaction pattern and FOS protein expression in male piglets undergoing surgical castration under light isoflurane anaesthesia with or without local anaesthesia. The experiment was conducted under isoflurane anaesthesia to exclude the effect of the affective components of pain on the measurements. Changes in the oscillatory activity of the cerebral cortex over a 90 s period after noxious stimulation or simulated interventions were analysed...

BACKGROUND: Maximizing patient comfort during hyaluronic acid gel injection is a common concern that is usually addressed by selecting fillers with lidocaine. OBJECTIVE: Two randomized, double-blinded, split-face trials aimed to demonstrate noninferiority of specific hyaluronic acid fillers incorporating mepivacaine (RHA-M) versus their lidocaine controls, at providing pain relief. METHODS: Thirty subjects per trial received injections of RHA R -M versus RHA R , and RHA4-M versus RHA4, respectively, in the perioral rhytids (PR) and nasolabial folds (NLF)...

In this work, magnetic tetraethylenepentamine (TEPA)-modified carboxyl-carbon nanotubes were synthesized, characterized, and used as adsorbents to conduct magnetic solid-phase extraction (MSPE) for the preconcentration of seven local anesthetic drugs (procaine, lidocaine, mepivacaine, oxybuprocaine, bupivacaine, tetracaine, and cinchocaine) from human plasma. The separation and determination of analytes were performed on high-performance liquid chromatography with UV detection. Several factors affected the extraction efficiency, such as the amount of adsorbents used, extraction time, sample pH, and optimization of elution conditions...

When choosing local anesthetics, risk factors such as underlying diseases, use of other medications and allergies have to be taken into consideration. Systematic complications might occur if a specific limit in the plasma concentration is exceeded. Articaine and prilocaine are metabolized extrahepatically. In case of an absolute contraindication for vasoconstrictors, the use of mepivacaine, bupivacaine or articaine is recommended.

AIM: To assess inferior alveolar nerve block (IANB) success of 2% mepivacaine (Scandonest 2%, Septodont, France) and 4% articaine (Septanest 4%, Septodont) in patients with symptomatic irreversible pulpitis (SIP) in mandibular molars during access cavity preparation and instrumentation. METHODOLOGY: Three hundred and thirty patients with moderate-to-severe pain in mandibular molars with SIP randomly received either 3.6 mL 2% mepivacaine hydrochloride with 1:100 000 adrenalin or 3...
