Aim Methods Results Conclusions To assess the effectiveness of intraoperative lidocaine in reducing the incidence of post‐laparoscopic shoulder pain (PLSP) after gynecologic laparoscopy.Patients undergoing total laparoscopic hysterectomy were randomly divided into two groups: the lidocaine group, receiving an initial intravenous dose of lidocaine (1.5 mg/kg) before anesthesia induction, followed by a continuous infusion at 2 mg/kg/h, and the placebo group, receiving saline. The primary endpoint was the determination of PLSP incidence over a 72‐h period post‐surgery. Secondary endpoints included a comprehensive evaluation of pain intensity, as measured by the Numeric Rating Scale (NRS), for shoulder, abdominal, and incisional pain within a 72‐hour period postoperatively. Additionally, the endpoints involved the assessment of Lofencodeine or Parexib Sodium usage frequency, incidence of nausea and vomiting, duration of anesthesia and surgical procedure, as well as the duration of hospital stay.Our study did not demonstrate any significant benefit in the incidence of PLSP during the postoperative period. PLSP occurred in 14 out of 41 patients (34.1%) in the lidocaine group, compared with 15 out of 41 patients (36.6%) in the placebo group (p = 0.817). Intravenous lidocaine reduced abdominal pain scores and decreased the need for postoperative analgesics within 72 h after surgery. No significant differences were found in incisional and shoulder pain intensity, nausea and vomiting rates, or hospitalization duration between groups.The infusion of lidocaine did not yield a reduction in the incidence or severity of PLSP in patients undergoing laparoscopic total hysterectomy.

Introduction Non-compressible torso hemorrhagic (NCTH) shock is the leading cause of potentially survivable trauma on the battlefield. New hypotensive drug therapies are urgently required to resuscitate and protect the heart and brain following NCTH. Our aim was to examine the strengths and limitations of permissive hypotension and discuss the development of small-volume adenosine, lidocaine, and Mg2+ (ALM) fluid resuscitation in rats and pigs. Materials and Methods For review of permissive hypotension, a literature search was performed from inception up to November 2023 using PubMed, Cochrane, and Embase databases, with inclusion of animal studies, clinical trials and reviews with military and clinical relevance. For the preclinical study, adult female pigs underwent laparoscopic liver resection. After 30 minutes of bleeding, animals were resuscitated with 4 mL/kg 3% NaCl ± ALM bolus followed 60 minutes later with 4 h 3 mL/kg/h 0.9% NaCl ± ALM drip (n = 10 per group), then blood transfusion. Mean arterial pressure (MAP) and cardiac output (CO) were continuously measured via a left ventricular pressure catheter and pulmonary artery catheter, respectively. Systemic vascular resistance (SVR) was calculated using the formula: 80 × (MAP − CVP)/CI. Oxygen delivery was calculated as the product of CO and arterial oxygen content. Results Targeting a MAP of ∼50 mmHg can be harmful or beneficial, depending on how CO and SVR are regulated. A theoretical example shows that for the same MAP of 50 mmHg, a higher CO and lower SVR can lead to a nearly 2-fold increase in O2 supply. We further show that in animal models of NCTH, 3% NaCl ALM bolus and 0.9% NaCl ALM drip induce a hypotensive, high flow, vasodilatory state with maintained tissue O2 supply and neuroprotection. ALM therapy increases survival by resuscitating the heart, reducing internal bleeding by correcting coagulopathy, and decreasing secondary injury. Conclusions In rat and pig models of NCTH, small-volume ALM therapy resuscitates at hypotensive pressures by increasing CO and reducing SVR. This strategy is associated with heart and brain protection and maintained tissue O2 delivery. Translational studies are required to determine reproducibility and optimal component dosing. ALM therapy may find wide utility in prehospital and far-forward military environments. [ABSTRACT FROM AUTHOR]

Objective: Lidocaine, a common local anesthetic in medical practice, exhibits anticancer properties across various tumor types. In this study, we aimed to investigate the effects and mechanisms of lidocaine on oral squamous cell carcinoma. Methods: Cell viability and proliferation were assessed through CCK‐8 and EdU assays. Transwell assays were used to analyze cell migration and invasion. Immunofluorescence assays were conducted to determine MMP9 levels. In vivo tumor growth was evaluated using a tumor xenograft model, and Ki67 and MMP9 levels were determined using immunohistochemistry. N6‐methyladenosine levels were assessed using dot plots and ELISA. mRNA and protein levels were examined through reverse transcription‐quantitative PCR or western blot analysis. The association between IGF2BP2 and caveolin‐1 was validated through RIP and luciferase reporter assays. Results: Lidocaine exhibited suppressive effects on the viability, migration, invasion, and tumor formation of oral squamous cell carcinoma. IGF2BP2 expression correlated with poor survival and was downregulated by lidocaine. Lidocaine reduced caveolin‐1 stability by decreasing IGF2BP2 levels. Caveolin‐1 overexpression partially reversed the suppressive effects of lidocaine on the progression of oral squamous cell carcinoma cells. Conclusion: Lidocaine exerts an anticancer role in oral squamous cell carcinoma via IGF2BP2‐mediated regulation of caveolin‐1 stability. [ABSTRACT FROM AUTHOR]

It remains unclear whether dosage adjustment of intravenous lidocaine is necessary during general anesthesia for elderly patients over 75 years old. This study aimed to investigate the effects of age on the pharmacokinetics (PK) and safety of intravenous lidocaine in patients undergoing general anesthesia. A total of 599 plasma samples were collected from 76 general anesthesia patients across three age groups: 18–64, 65–74, and ≥ 75 years. Lidocaine was administered intravenously at a dose of 1.5 mg/kg for the 18–64 and 65–74 years groups, while the dose was adjusted to 1.0 mg/kg for the ≥ 75 years group. The plasma concentrations of lidocaine and its active metabolites were measured using a validated ultra-performance liquid chromatography-tandem mass spectrometry assay, and the data were analyzed using a noncompartmental analysis. The results revealed no significant age-related differences in the PK of lidocaine and its metabolites. Among the three age groups, over 90 % of patient achieved a lidocaine concentration within a safe and effective range when the dosage was normalized to 1.5 mg/kg. In conclusion, age-based dosage adjustment was unnecessary for intravenous lidocaine in patients below 86 years undergoing general anesthesia. [ABSTRACT FROM AUTHOR]

Introduction Extubation is associated with hemodynamic changes and emergence phenomena leading to cough, sore throat, dysphonia, and dysphagia in the postoperative period. The aim of our study was to compare intracuff 2% alkalinized lignocaine with 1% alkalinized lignocaine and saline in reducing endotracheal tube induced emergence phenomena and haemodynamic changes at extubation in neurosurgical patients. Materials and Methods In this randomized controlled study, 90 adult patients of either sex, scheduled to undergo neurosurgical procedures were randomly divided into three groups of 30 each to receive either 1% alkalinized lignocaine (AL1), 2% alkalinized lignocaine (AL2), or saline as cuff inflation media. Intracuff pressures and haemodynamic variables were noted intraoperatively and during emergence. The presence of postextubation cough, sore throat, dysphonia, and dysphagia were monitored until 24 hours postoperatively. Data were analyzed using Chi-square test and ANOVA. A p -value of less than 0.05 was considered significant. Results The intracuff pressures were significantly less with alkalinized lignocaine as compared to saline, after 3 hours of induction. Post extubation, hemodynamic parameters and incidence of coughing and bucking at extubation were significantly less in Groups AL1 (p = 0.024) and AL2 (p = 0.02) as compared to saline. On assessment of laryngotracheal morbidity, the incidence of coughing was found to be significantly less with 2% alkalinized lignocaine as compared to saline (p = 0.021) at 1 hour after extubation. Sore throat was significantly less in Groups AL1 and AL2 as compared with saline at 1 hour (p = 0.008, 0.002 respectively) and 8 hours (p = 0.01 in both groups), and in Group AL2 versus saline at 24 hours (p = 0.044) after extubation. The incidence of dysphonia was significantly less in Groups AL1 and AL2 as compared with saline at 1 hour (p = 0.016, p = 0.002) and 24 hours (p = 0.012 in both groups) and in Group AL2 versus saline at 8 hours (p = 0.03) postoperatively. No significant differences were noted between 1% alkalinized lignocaine and 2% alkalinized lignocaine. Conclusion Intracuff alkalinized lignocaine 1% and 2% were significantly better than saline in reducing coughing and bucking at extubation, post extubation haemodynamic changes and incidence of postoperative cough, sore throat, and dysphonia.

Background: Trigeminal nerve injury following endodontic treatment, leading to unpleasant sensations or partial sensory loss in the face or oral mucosa, is uncommon but significant when it occurs. Objective: This study analysed the pharmacological management of trigeminal nerve injuries (TNI) in a university‐based hospital. Methods: We conducted a retrospective analysis of 47 patients who visited the Department of Orofacial Pain and Oral Medicine at Yonsei University Dental Hospital, Seoul, Korea, after TNI following endodontic procedures in primary clinics. Both objective tests and subjective evaluations, assessed the extent and duration of sensory injury during the initial visit. The patient's initial symptoms, presumed cause of TNI, referral delay (time interval between TNI and the first visit to our clinic), and medications were analysed to determine whether these factors affected the outcomes. Results: Most patients with TNI experienced dysesthesia with hypoesthesia (70.2%). The mandibular molars were predominantly affected (72.3%), with the inferior alveolar nerve (IAN), lingual nerve (LN), both IAN and LN, and maxillary nerve compromised in 83.0, 12.8, 2.1, and 2.1% of cases, respectively. Causes of TNI included local anaesthesia (29.8%), overfilling/over‐instrumentation (25.5%), endodontic surgery (17.0%), and unknown factors (27.7%). A shorter referral delay was associated with better outcomes, with an average delay of 8.6 weeks for symptom improvement compared with 44.1 weeks for no change. The medication regimens included steroids, NSAIDs, topical lidocaine, vitamin B complex, Adenosine Triphosphate (ATP), antiepileptics, antidepressants, and opioids administered alone or in combination, with a mean duration of 20.7 weeks. 53.2% of the patients reported improvement in their symptoms, 27.7% experienced no significant change, and 19.1% had unknown outcomes. Conclusions: Swift referral to an orofacial pain specialist is recommended for effective recovery in cases of TNI arising from endodontic treatment. [ABSTRACT FROM AUTHOR]

Statement of the Problem: Conventional injection technique with adrenaline during removal of impacted third molar of mandible had proportionally increased pain during administration with slow onset of action and shorter duration of anesthesia. Purpose: The purpose of this study was to compare the effective nature of 8.4% and 7.5% buffered lidocaine hydrochloride during surgical removal of mandibular impacted third molar. Materials and Method: This prospective crossover study included 50 patients requiring bilateral removal of impacted mandibular third molars. Group I included 50 impacted mandibular third molars that were administered with 8.4% buffered lidocaine hydrochloride and group II included 50 impacted mandibular third molars were administered with 7.5% buffered lidocaine hydrochloride. The outcome variables were pain on injection, time of onset of anesthesia, and duration of action of anesthesia. The above parameters were recorded by the investigator and statistically analyzed through Chi-square test using SPSS software. Results: Patients in group I had mild pain (1.02) and patients in group II (5.74) had moderate pain with a statistical significance of p< 0.05 for group I respectively. The mean onset of action of anesthesia in group I was 0.08 seconds and 0.59 seconds in group II (p< 0.05). The duration of anesthesia was 342.51 minutes from group I and 122.06 minutes in group II (p< 0.05) respectively. Conclusion: Lidocaine hydrochloride buffered with 8.4 % sodium bicarbonate was found to be more effective in reduction of pain during injection, also had a faster onset of action and longer duration of the action of anesthesia when compared to 7.5% buffered lidocaine hydrochloride.

- Abstract
This double-blind, randomised clinical trial aimed to find out whether there is a difference in the prevalence of neurosensory disturbance (NSD) between patients who received 2% lidocaine and those who received 4% articaine during inferior alveolar nerve blocks (IANBs). Patients who underwent third molar extraction were randomised into two groups. IANB was performed using 2% lidocaine in Group 1 and 4% articaine in Group 2. The occurrence of NSD was documented. Patients were visited within 48 hours and one week after the tooth was removed. The type of anaesthetic drug (4% articaine versus 2% lidocaine) was the study's predictive factor. A total of 2400 patients were studied in two groups (1200 in each group). The mean (range) age of the patients was 28.40 (18–44) years. Five patients (0.41%) in the lidocaine group and seven (0.58%) in the articaine group had NSD after injection (p = 0.77). The prevalence of NSD after IANB was no higher in the articaine group than in the lidocaine group. [ABSTRACT FROM AUTHOR]

Sánchez Roldán, M. Ángeles, Duque, Héctor, Masso, Bernat, Moncho, Dulce, Vilallonga, Ramón, Armengol, Manuel, and González, Óscar
- Abstract
The laryngeal adductor reflex (LAR) is a brainstem reflex that closes the vocal fold and constitutes a new method for continuously monitoring the vagus and laryngeal nerves during different surgeries. Previous reports concluded that topical lidocaine in spray inhibited LAR responses. However, topical anesthesia in the upper airway may be necessary in awake intubation. We present six patients who underwent neck endocrine surgery due to an intrathoracic goiter that compromised the airway. Before awake intubation, a nebulization of lidocaine 5% was applied for at least 10 min. The intubation procedure was well tolerated, and bilateral LAR with suitable amplitudes for monitoring was obtained in all cases. In our series, the nebulization of lidocaine 5% did not affect the laryngeal adductor reflex. Laryngoscope, 134:4161–4164, 2024 [ABSTRACT FROM AUTHOR]

- Abstract
Background The infraorbital hollow (IOH) is a concavity that interrupts the smooth transition between the lower eyelid and the cheek, resulting in a fatigued and aged appearance. Injectable fillers may be utilized to correct volume deficit in the under-eye area, restoring a more youthful appearance. Objectives The objective was to demonstrate the effectiveness and safety of a cohesive polydensified matrix (CPM) hyaluronic acid (HA) filler with lidocaine (Belotero Balance (+)) for correcting volume deficit in the IOH. Methods Eligible patients with a moderate or severe rating on the Merz Infraorbital Hollow Assessment Scale (MIHAS) were randomized 2:1 to treatment or control. Controls remained untreated until Week 8 and were then treated. Touch-up injections were allowed; retreatment was offered only in the treatment group. Effectiveness was evaluated with the MIHAS. Adverse events were recorded over a 76-week period. Results The estimated average response rate (≥1 point MIHAS improvement) was 80.6% (95% CI, 71.4-87.4) in treated patients and 1.9% (95% CI, 0.3-10.2) in controls at Week 8. The difference in estimated response rates was 78.7% (95% CI, 66.3-85.6), demonstrating a statistically significant, superior response rate in treated patients compared to untreated controls. A total of 88 of 97 (90.7%) patients who responded to treatment at Week 8 retained improvement 48 weeks after treatment. Use of Belotero Balance (+) in the IOH had a favorable safety profile, with no unexpected adverse events reported. Conclusions Belotero Balance (+) is a safe and effective treatment for correcting volume deficit in the IOH. [ABSTRACT FROM AUTHOR]

Objectives Animals and Procedures Results Conclusions Accurate intraocular pressure (IOP) measurement is essential for managing glaucoma, requiring tonometry. Local anesthesia is typically used, but nerve blocks may be needed for blepharospasm. This study investigated the efficacy of auriculopalpebral nerve block with lidocaine in achieving eyelid akinesia and its influence on IOP in dogs.In a randomized, blinded trial, 12 healthy adult mixed‐breed dogs (24 eyes) received either auriculopalpebral nerve block with 2% lidocaine (n = 12 eyes) or no block (n = 12 eyes). Tetracaine drops were used for topical anesthesia in half of blocked/non‐blocked eyes, and the rest of the eyes got artificial tears as control. The impact of nerve block was evaluated through assessments of menace response, palpebral reflex, and IOP before the block, after drop instillation, and at 15‐min intervals until block dissipation.Auriculopalpebral nerve block provided effective eyelid akinesia in 58.5% (7/12 eyes) at 15 min, reaching 91.7% (11/12 eyes) at 30 min, indicating peak efficacy. Subsequently, the block gradually diminished, with 66.7% (8/12 eyes) and 33.3% (4/12 eyes) maintaining akinesia at 45 and 60 min, respectively. Importantly, neither auriculopalpebral nerve block nor tetracaine administration significantly affected IOP measurements (p > .05).Auriculopalpebral nerve block using lidocaine demonstrated efficient eyelid akinesia, peaking at 30 min postinjection. This technique proved to be safe with no notable alterations in IOP, suggesting its potential utility in canine ophthalmology for procedures requiring eyelid akinesia, particularly in the management of glaucoma where maintaining accurate IOP measurements is crucial for diagnosis, treatment, and monitoring the disease.

The dose–response of intravenous lidocaine in preventing postoperative vomiting (POV) in children remains unclear. This study investigated whether intravenous lidocaine dose-dependently decreased POV risk within 24 h postoperatively in children undergoing tonsillectomy (with or without adenoidectomy) without severe complications. Patients aged 3–12 years (American Society of Anesthesiologists grade I–II) scheduled for elective tonsillectomy (with or without adenoidectomy) were enroled from December 2021 to March 2022. They were randomly grouped according to the lidocaine dose (A [0 mg kg−1], B [1 mg kg−1], C [1.5 mg kg−1], and D [2 mg kg−1]) and were administered the same induction protocol (sufentanil, propofol, and suxamethonium chloride). Anaesthesia was maintained with sevoflurane. The incidence of POV within 24 h postoperatively was 46, 40, 36, and 20% in groups A, B, C, and D, respectively, with significant differences between groups D and A. Postoperative analgesic rescues in groups A, B, C, and D were 62, 36, 34, and 16%, respectively, with significant differences between groups D and B, C and A, and D and A. No severe adverse events were reported. Intravenous lidocaine has a dose-dependent effect on reducing the risk of POV in children undergoing tonsillectomy (with or without adenoidectomy) without serious adverse events.

Simple Summary: Castration of male piglets without anaesthesia is facing increasing rejection in society and is also questionable for animal welfare reasons. In this study, the intranasal application of azaperone, azaperone combined with alfaxalone and azaperone combined with midazolam in various doses was tested for its suitability to ensure adequate sedation in combination with intratesticular local anaesthesia during the surgical castration of male piglets. Compared to intramuscular application, intranasal application consistently showed a poorer quality of sedation. Therefore, the intranasal application method cannot be recommended. The aim of this study was to test the intranasal administration of different anaesthetics in piglets less than seven days of age undergoing castration for their suitability for providing good-quality sedation and short induction and recovery time with minimal stress. Azaperone alone at a high (5 mg/kg), medium (3 mg/kg) and low dosage (2 mg/kg) and in two combinations with either alfaxalone or midazolam were applied intramuscularly (i.m.) or intranasally (i.n.) to 120 healthy piglets. Compared to intramuscular application, intranasal application showed longer induction times, shorter recovery times and higher scores for defence and vocalisation. In conclusion, the intranasal protocols did not meet the requirements in all groups and their use can therefore not be recommended. A rapid induction phase and good quality of sedation could not be guaranteed. [ABSTRACT FROM AUTHOR]

This study aimed to investigate the effects of the intravenous administration of lidocaine in the auditory cortex after the systemic administration of salicylate. Healthy male albino Hartley guinea pigs were divided into two groups. The control group received only lidocaine, whereas the experimental group received lidocaine after checking for the effects of salicylate. Extracellular recordings of spikes in the primary auditory cortex and dorsocaudal areas in healthy albino Hartley guinea pigs were continuously documented (pre- and post-lidocaine, pre- and post-salicylate, and post-salicylate after adding lidocaine to post-salicylate). We recorded 160 single units in the primary auditory cortex from five guinea pigs and 155 single units in the dorsocaudal area from another five guinea pigs to confirm the effects of lidocaine on untreated animals. No significant change was detected in either the threshold or Q10dB value after lidocaine administration in the primary auditory cortex and dorsocaudal areas. Spontaneous firing activity significantly decreased after lidocaine administration in the primary auditory cortex and dorsocaudal areas. Next, we recorded 160 single units in the primary auditory cortex from five guinea pigs and 137 single units in the dorsocaudal area from another five guinea pigs to determine the effects of lidocaine on salicylate-treated animals. The threshold was significantly elevated after salicylate administration; however, no additional change was detected after adding lidocaine to the primary auditory cortex and dorsocaudal areas. Regarding the Q10dB value, lidocaine negated the significant changes induced by salicylate in the primary auditory cortex and dorsocaudal areas. Moreover, lidocaine negated the significant changes in spontaneous firing activities induced by salicylate in the primary auditory cortex and dorsocaudal areas. In conclusion, changes in the Q10dB value and spontaneous firing activities induced by salicylate administration are abolished by lidocaine administration, suggesting that these changes are related to the presence of tinnitus.

We aimed to compare the parasagittal and transverse approaches for ultrasound-guided superior laryngeal nerve block in adult patients undergoing awake intubation. Methods: Fifty patients with awake orotracheal intubation were randomized to receive either a parasagittal or transverse ultrasound-guided superior laryngeal nerve block. The primary outcome was patient's quality of airway anesthesia grade during insertion of the tube into the trachea. The patients' tube tolerance score after intubation, total procedure time, mean arterial pressure, heart rate, Ramsay sedation score at each time point, incidence of sore throat both 1 h and 24 h after extubation, and hoarseness before intubation, 1 h and 24 h after extubation were documented. Results: Patients' quality of airway anesthesia was significantly better in the parasagittal group than in the transverse group (median grade[IQR], 0 [0–1] vs. 1 [0–1], P = 0.036). Patients in the parasagittal approach group had better tube tolerance scores (median score [IQR],1[1–1] vs. 1 [1–1.5], P = 0.042) and shorter total procedure time (median time [IQR], 113 s [98.5–125.5] vs. 188 s [149.5–260], P < 0.001) than those in the transverse approach group. The incidence of sore throat 24 h after extubation was lower in the parasagittal group (8% vs. 36%, P = 0.041). Hoarseness occurred in more than half of the patients in parasagittal group before intubation (72% vs. 40%, P = 0.023). Conclusions: Compared to the transverse approach, the ultrasound-guided parasagittal approach showed improved efficacy in terms of the quality of airway topical anesthesia and shorter total procedure time for superior laryngeal nerve block. Trial registration: This prospective, randomized controlled trial was approved by the Ethics Committee of Nanjing First Hospital (KY20220425-014) and registered in the Chinese Clinical Trial Registry (19/6/2022, ChiCTR2200061287) prior to patient enrollment. Written informed consent was obtained from all participants in this trial. [ABSTRACT FROM AUTHOR]

Background: Post-operative sore throat (POST) is a very common anesthesia-related event which may hamper patient satisfaction and increase treatment cost. Aims and Objectives: This study aimed to compare the effectiveness of nebulization with dexamethasone and lignocaine to prevent POST. Materials and Methods: This randomized controlled study involved 135 patients randomly divided into three equal groups: Group D - (n=45) received 8 mg (2 mL) dexamethasone plus 3 mL of distilled water, Group L - (n=45) received 80 mg (4% lignocaine 2 mL) plus 3 mL distilled, and Group S - (n=45) received nebulization with 5 mL normal saline. Results: At 4 h postoperatively, the incidence of POST was 15.6% in the dexamethasone group, 33.3% in the lignocaine group, and 73.3% in the saline group. The score was significantly higher in the saline group (P=0.001) compared to the dexamethasone and lignocaine group, while it was comparable between dexamethasone and lignocaine group (P=0.188). Similarly, dexamethasone and lignocaine groups were comparable at immediately post-operative, 2, 8, 12, and 24 h post-operative time points. Post-operative hoarseness scores of all three groups were comparable at all-time points. A significant increase in the heart rate (HR) and mean arterial pressure (MAP) after intubation was observed in the saline and dexamethasone group as compared to the lignocaine group (P=0.001) while HR and MAP were comparable in dexamethasone and saline group (P=1.000). Conclusion: Dexamethasone and lignocaine nebulization are both effective and comparable prophylaxis for POST and lignocaine nebulization has added advantage of blunting pressor response to endotracheal intubation over dexamethasone nebulization.

Purpose: Radial tunnel syndrome (RTS) is a controversial diagnosis due to non-specific exam findings and frequent absence of positive electromyography (EMG) and nerve conduction study (NCS) findings. The purpose of this study was to identify the methods used to diagnose RTS in the literature. Methods: We queried PubMed, Embase, Web of Science, and Cochrane databases per PRISMA guidelines. Extracted data included article and patient characteristics, diagnostic assessments utilized and their respective findings, and treatments. Objective data were summarized descriptively. The relationship between reported diagnostic findings (i.e., physical exam and diagnostic tests) and treatments was assessed via a descriptive synthesis. Results: Our review included 13 studies and 391 upper extremities. All studies utilized physical exam in diagnosing RTS; most commonly, patients had tenderness over the radial tunnel (381/391, 97%). Preoperative EMG/NCS was reported by 11/13 studies, with abnormal findings in 8.9% (29/327) of upper extremities. Steroid and/or lidocaine injection for presumed lateral epicondylitis was reported by 9/13 studies (46/295 upper extremities, 16%), with RTS being diagnosed after patients received little to no relief. It was also common to inject the radial tunnel to make the diagnosis (218/295, 74%). The most common reported intraoperative finding was narrowing of the PIN (38/137, 28%). The intraoperative compressive site most commonly reported was the arcade of Frohse (142/306, 46%). Conclusions: There is substantial heterogeneity in modalities used to diagnose RTS and the reported definition of RTS. This, in conjunction with many patients having concomitant lateral epicondylitis, makes it difficult to compare treatment outcomes for RTS. Level of evidence: Level III.

SPRAGUE Dawley rats , *FEAR of dentists , *LOCAL anesthetics , *ELECTRONIC tongues , *DENTAL anesthesia - Abstract
Lidocaine hydrochloride (HCl) 2% with 1:100,000 epinephrine (LW/E) is widely used to prevent pain during dental procedures and has been associated with injection sting, jittering effects, slow onset, and a bitter aftertaste. Since LW/E's introduction in 1948, no significant modifications have been proposed. This study aims to design and characterize an improved dental lidocaine HCl injectable formulation without epinephrine (LW/O/E) via buffers, sweeteners, and amino acids. LW/O/E injections were prepared with pH and osmolality values of 6.5–7.0 and 590–610 mOsm/kg. Using the electronic tongue (ETongue), the LW/O/E injectable formulations were characterized for viscosity, injectability, and taste analysis. The results were compared with the LW/E control. In vivo efficacy and anesthetic duration of the samples were measured through radiant heat tail-flick latency (RHTFL) and hot plate (HP) tests and local toxicity was assessed after a single intra-oral injection in Sprague Dawley rats (SDR). The viscosity and injectability values of the LW/O/E samples were found to be comparable to the LW/E injection. ETongue taste analysis showed an improvement in bitterness reduction of the LW/O/E samples compared to the LW/E formulation. Toxicity studies of samples in SDR showed minor and transient signs of erythema/eschar and edema. Anesthetic duration via RHTFL and HP paw withdrawal latency time in SDR were found to be comparable for the LW/O/E Sample 3A and the LW/E injection (p < 0.05). In conclusion, the buffered, higher osmolality and reduced bitterness developed LW/O/E formulation (Sample 3A) could be considered a promising alternative to the LW/E formulation for dental use.

Introduction: Pain related to injection of propofol during induction of anesthesia decreases from 66.8% without prevention, to 22–31% of cases when lidocaine is associated. Hypnoanalgesia of the hand is currently used for painful procedures in children but has never been evaluated in this indication. The primary aim of this prospective randomized single‐blind study was to evaluate the efficacy of hypnoanalgesia of the hand for the prevention of moderate to severe pain during intravenous injection of propofol alone in comparison to lidocaine admixture. The secondary aim was to compare the global satisfaction of children in both methods. Patients and Methods: One hundred patients aged 7–14 years, ASA 1‐2, admitted for scheduled surgery under general anesthesia were randomized into two groups. Group L received a mixture of 1% propofol (3 mg/kg) and 1% Lidocaine (0.3 mg/kg). Group H received 1% propofol (3 mg/kg) after hypnoanalgesia of the hand realized by a single experimented operator. A video was made in order to evaluate the pain related to propofol injection by a blinded observer using the 4‐point score of Cameron (painful ≥ 2). The global satisfaction of children was evaluated in postanesthesia care unit and documented if visual analog score was <7/10. Results: Ninety‐six patients were analyzed. The rate of painful patients did not differ significantly between groups (8.5% in group H [n = 47] vs 6.1% in group L [n = 49], OR= 0.70; 95% CI [0.13–3.35], p = 0.65), nor did the rate of nonsatisfied patients (10.6 in group H vs. 12.2% in group L, OR = 0.85; 95% CI [0.19–3.65], p = 1). Conclusions: Our results suggest that hypnoanalgesia of the hand alone is effective to prevent the pain related to propofol injection in children. No significant difference was found in comparison with lidocaine admixture nor for pain or satisfaction. [ABSTRACT FROM AUTHOR]

Background: The local anaesthetic lidocaine is widely used in the neonatal intensive unit to treat seizures in premature babies. However, other antiepileptics administered during early development in various animal models have shown negative long‐term behavioural effects. Since no long‐term behavioural data so far exist regarding lidocaine exposure at an early age, we decided to perform this extended follow‐up study using a sensitive behavioural test. Methods: Neonatal mice received a subcutaneous administration of saline or one dose of lidocaine (0.5, 4, or 12 mg kg−1) on postnatal day 10 (P10; peak of the Brain Growth Spurt). A well‐established test to detect long‐term behavioural alterations was conducted at 2 and 6 months of age, corresponding to early and late adulthood in humans. Results: All animal survived to later testing. No signs of acute toxicity were observed. Lidocaine exposure did not result in any negative behavioural effects during habituation to a new home environment at any of the two studied time points, compared to saline placebo. Conclusions: Lidocaine does not by itself produce any negative long‐term behavioural effects in mice exposed in early life (P10) despite long‐term follow‐up. This is reassuring regarding the current practice of treating seizures in premature babies with intravenous lidocaine. [ABSTRACT FROM AUTHOR]

Background Sympathetic-mediated vasoconstriction from the superior cervical ganglion (SCG) is a significant contributor to cerebral vasospasm. Inhibition of the SCG has been shown to improve cerebral blood flow and reverse cerebral vasospasm in swine models. We evaluated the efficacy of a novel minimally invasive endovascular approach to target and pharmacologically inhibit the SCG, using a Micro-Infusion Device for transmural drug delivery. Methods Eight SCGs in four Yorkshire swine were surgically identified. After confirming appropriate sympathetic-mediated intracranial vasoconstriction response with SCG stimulation, an endovascular Micro- Infusion Device was used for transmural targeting of the SCG and delivery of 1.5--2 mL of 1% lidocaine-contrast mixture to the perivascular space. Digital subtraction angiography was obtained at: (1) baseline; (2) with SCG stimulation; and (3) after lidocaine delivery to the SCG using the Micro-Infusion Device with concurrent SCG stimulation. Vessel diameters were measured and compared. Results Endovascular transmural delivery of lidocaine to the SCG and carotid perivascular tissue using the Micro-Infusion Device successfully inhibited sympathetic-mediated vasoconstriction response. Measured vessel diameters after lidocaine delivery were comparable to baseline despite SCG stimulation. Conclusion A novel endovascular technique of transmural delivery of lidocaine to the SCG and carotid artery perivascular tissues successfully inhibits the sympathetic input to the cerebral vasculature and modulates sympathetic-mediated cerebral vasospasm. These results suggest promising steps towards translation to potential clinical use for patients suffering from cerebral vasospasm. [ABSTRACT FROM AUTHOR]

Paediatric supraventricular tachycardia (SVT) is a common arrhythmia of great clinical significance. If not treated promptly, it can cause heart failure and cardiogenic shock. Depending on the patient's condition, SVT treatment involves vagal manoeuvres, pharmacological, or direct current cardioversion. The goal of acute SVT management is to immediately convert SVT to a normal sinus rhythm (NSR) and prevent its recurrence. Adenosine is recommended as the first-line treatment for stable SVT by the European Resuscitation Council (ERC) and American Heart Association (AHA) guidelines, when vagal manoeuvres have proven ineffective. The ERC and AHA guidelines recommend the intravenous route of administration. The intraosseous (IO) administration technique is also possible, but still relatively unknown. The aim of this paper is to describe a 3.5-year-old child with SVT that was converted to NSR following IO administration of adenosine. Successful conversion was achieved after the second attempt with the adenosine dose. In the described case, there was no recurrence of SVT. [ABSTRACT FROM AUTHOR]

Introduction: Solid organ transplant recipients are at high risk for developing severe zoster-associated neuralgia, and the pharmaceutic therapies of pain management for these patients with limited organ function are challenging. Intravenous lidocaine infusion showed positive analgesic effects and is used for the management of neuropathic pain. This case series reports the safety and effectiveness of intravenous lidocaine infusion in the treatment of intractable zoster-associated neuralgia in solid organ transplant recipients. Case series presentation: Five solid organ transplant recipients suffering from refractory zoster-associated neuralgia (numeric rating scale 8-10, despite using high doses of antiepileptic drugs or combined with opioids) were enrolled. Intravenous lidocaine (5 mg/kg ideal bodyweight) was administered over 1.5 h with the monitoring of vital signs. Pain intensity, patient satisfaction, adverse events, typical liver, and kidney function were evaluated. All subjects reported high satisfaction with their treatment and effective pain relief at the 6-month follow-up. One patient experienced short and mild numbness in the mouth and dizziness after the therapy, but no major adverse reactions were reported. Conclusion: This case series provides evidence that intravenous lidocaine infusion provided effective pain relief as an analgesic treatment option for transplant patients with intractable zoster-associated neuralgia.

- Abstract
The present study investigated the effectiveness of intra-operative bupivacaine–lidocaine (BLK) combination administration concurrently with meloxicam, a non-steroidal anti-inflammatory drug (NSAID), on the Glasgow Composite Pain Scale Short Form (GCPS-SF) scores and pain mediators in the early post-operative ovariohysterectomy (OHE) period in 30 female dogs of different breeds and ages divided into three equal groups. OHE is reportedly associated with moderate pain. BLK was administered inside the ovarian bursa 10 min before ovary removal in Groups (G) 1 and G2 and linear to the incision line 10 min before entering the abdomen in G1. G3 was the control group. The intergroup comparison of pain mediators and GCPS-SF scores showed no significant difference between the GCPSSF scores at postop0, postop2, postop4, postop8 and postop24 h and the cortisol, TNF-α, IL1-β and NO levels determined at the same timepoints. TNF-α at postop24 h showed a significant positive correlation with the postop0 h GCPS-SF score. NO at postop8 h showed a significant negative correlation with the postop4 h GCPS-SF score. However, since these results were not simultaneous, they were disregarded. Although there was no statistically significant difference in post-operative pain and stress among the three groups, surgical stress was higher in G3, as indicated by high postoperative cortisol levels, which suggested the other two protocols involving BLK to be remarkable. Hence, using G1 and G2 protocols appeared feasible considering the post-operative cortisol stress hormone values. Nevertheless, further studies with larger samples are warranted to confirm these inferences. [ABSTRACT FROM AUTHOR]

Background and objectives: The main problem of vascular preservation is the maintenance of vessel graft quality and function following extended storage. Conventional preservation solutions such as histidine–tryptophan–ketoglutarate (HTK) solution, Phosphate-Buffer Solution (PBS), or sodium chloride 0.9% has been shown to be inadequate in preserving vascular physiological function after 3 days of cold storage. This study aimed to evaluate whether adenosine and lidocaine (AL) in a modified Krebs–Henseleit (KH) solution can preserve the function and histological structure of rat aortic rings after 6 days. Materials and Methods: Thirty-five aortic rings from male Wistar rats (200–300 g) were harvested and immediately immersed in one of the assigned cold preservation solutions: standard KH, modified KH (mod KH) with lower calcium (Ca
2+ ) and higher magnesium content (Mg2+ ) with or without adenosine and lidocaine (mod KH-AL), and modified KH with AL, insulin, and melatonin (Mod KH-ALMI). The contraction and relaxation function of the aortic rings were examined using an isometric force transducer after 6 days of cold preservation. Hematoxylin and eosin staining were used to analyze the rings' histological structure. Results: Vascular contraction and relaxation functions were severely affected after a 6-day cold storage period in standard KH. Modifying the KH solution by reducing the Ca2+ and increasing the Mg2+ levels greatly recovered the vessel functions. The addition of AL or ALMI to the modified KH did not further recover vascular contractility. However, only the addition of AL to the modified KH increased the ACh-induced relaxation at 6 days when compared to the conventional KH, suggesting that endothelium preservation is improved. From histological analysis, it was found that the addition of AL but not ALMI further improved the endothelial lining and the structure of the elastic membrane layers of the preserved vessels after 6 days of cold preservation. Conclusions: The addition of AL to low calcium-high magnesium KH solution significantly enhanced endothelial preservation and improved endothelial-induced relaxation of preserved vessels after 6 days of cold storage.

Background: Carcinoid tumors are rare neuroendocrine malignancies presenting in an increasing number in our center. The incidence of carcinoid tumors is approximatively between 2.5 and 5 cases per 100,000 people of whom about 50% develop carcinoid syndrome. Once the carcinoid syndrome has developed, a carcinoid cardiomyopathy can occur. Carcinoid heart disease (CaHD) remains a serious and rare complication associated with a significant increase in morbidity and mortality. Although carcinoid tumors have been known and studied for several years, there are still scarce data on the anesthetic management and the peri operative period. Case presentation: We describe a case of a Caucasian 44-year-old woman with an unusual presentation of left CaHD with an ileal neuroendocrine tumor and liver metastases. Our preoperative somatostatin administration protocol, limit the cardiac damage. The maintenance of stable hemodynamics, the use of balanced anesthetic technique, all along with a good understanding of the pathology, played a major role in the successful management of anesthesia. This case report allows us to introduce our decision algorithm for the management of this type of pathology in our tertiary hospital, Cliniques Universitaires Saint-Luc. Conclusion: Despite the paucity of data, anesthetic management of patients with carcinoid tumor can be safely performed with effective hemodynamic monitoring and a good understanding of the pathophysiology. Knowledge and application of a clear institutional algorithm for octreotide administration and multidisciplinary consultation at a referral center are essential for the management of these patients.

Background: Post-operative sore throat is the common complaint and uncomfortable side effect in patients receiving general anesthesia with endotracheal intubation. Drugs with analgesic and anti-inflammatory properties, like steroids and local anesthetics, are the best options for postoperative sore throat prophylaxis. Therefore, this study aimed to compare the effects of intravenous lidocaine and dexamethasone in reducing postoperative sore throat following endotracheal extubation at Tikur Anbessa Specialized Hospital, Addis Ababa, Ethiopia, from January 1 to March 30, 2023 G.C. Methods: A prospective cohort study was carried out at Tikur Anbessa Specialized Hospital. Data from 50 patients in the lidocaine (1.5 mg/kg), 50 in the dexamethasone (8 mg), and 49 in the control groups were analyzed. The data were collected using observation based on structured questionnaires. A systematic random sampling technique was applied to select respondents. The data were entered into EpiData version 4.6.0.6 and transferred to STATA version 17 statistical software for analysis. A comparison of continuous data among the groups were performed using a one-way ANOVA test for parametric data. The Kruskal–Wallis rank test was used for non-parametric data. Associations between variables were tested using chi-squared test, Fisher's exact test, and binary logistic regression. Bivariable and multivariable logistic regression was used to determine degree of association. Results: The incidence of POST was 40%, 32%, and 57.1% in the lidocaine, dexamethasone, and control groups, respectively (P =.0356). Dexamethasone reduced the incidence of POST during the first 24 h (AOR: 0.374, 95% CI: 0.149–0.939). However, no difference was observed in the severity of POST at 3 h (p = 0.130), 6 h (p = 0.096), 12 h (p = 0.313), and 24 h (p = 0.525) of the post-extubation period among the three groups. IV lidocaine did not effectively reduce the incidence and severity of postoperative sore throat at different time intervals. Conclusion and recommendation: Intravenous dexamethasone is more effective than intravenous lidocaine in reducing the incidence of postoperative sore throat among the groups. Based on these findings, intravenous dexamethasone is recommended to decrease the incidence of postoperative sore throat. [ABSTRACT FROM AUTHOR]

Background: It is aimed to compare the block onset times and performance features of costoclavicular techniques (medial and lateral approach) versus lateral sagittal technique. Methods: Patients were randomized into three groups. For costoclavicular techniques, ultrasound probe was placed parallel to clavicle obtaining nerve cords, axillary artery and axillary vein visual from lateral-to-medial, respectively. The block needle was advanced from lateral (Group CLB) or medial (Group CMB) to perform costoclavicular block. For lateral sagittal technique (Group LSB), ultrasound probe was placed sagittal and perpendicular below the coracoid process to obtain sagittal artery image with the cords around. Total 20 ml of 0.5% bupivacaine and 10 ml of 2% lidocaine were deposited for all groups. Sensory and motor block onset times, block performance properties, complications, and patient/surgeon satisfactions were investigated. Results: Among 56 patients, the primary outcome, sensory block onset time was shorter in Group CLB than Group CMB and Group LSB (10 [5–15], 10 [10–20], and 15 [10–15] minutes, respectively, p < 0.05). Motor block onset was also fastest in Group CLB (15 [10–20] mins for CLB, 20 [15–20] mins for LSB, and 22.5 [15–25] mins for CMB, p = 0.004). Block performance properties did not differ between the groups. The only complication observed was vascular puncture with an incidence of 28% in Group CMB. Conclusions: Lateral approach costoclavicular technique provides fastest block onset than the other techniques.

Background: Intravenous lidocaine has shown promise as an effective analgesic in various clinical settings, but its utility for pain management in emergency departments, especially for bone fractures, remains relatively understudied. Objective: This study compared intravenous lidocaine to pethidine for femoral bone fracture pain management. Methods: This double-blind, randomized, controlled clinical trial was conducted in the emergency department of AJA University of Medical Sciences affiliated hospitals. Patients aged 18–70 years-old with femoral bone fracture and experiencing severe pain, defined as a numerical rating scale (NRS) of pain ≥ 7, were included in the study. One group received intravenous pethidine (25 mg), while the other group received intravenous lidocaine (3 mg/kg, not exceeding 200 mg), infused with 250 ml saline over 20 min. Pain levels were evaluated before treatment administration (0 min) and at 10, 20, 30, 40, 50, and 60 min after treatment administration using the NRS. Results: Seventy-two patients were enrolled in the study. Demographic characteristics and pain scores were similar between the two groups. The mean pain scores upon arrival for the lidocaine and pethidine groups were 8.50 ± 1 and 8.0 ± 1, respectively; after one hour, they were 4.0 ± 1 and 4.0 ± 1, respectively. While there was a statistically significant reduction in pain in both groups after one hour, there were no clinically or statistically significant differences between the two groups (p = 0.262). Pethidine had a higher incidence of adverse events, though not statistically significant. Additionally, females required more rescue analgesics. Conclusion: The administration of intravenous lidocaine is beneficial for managing pain in femoral bone fractures, suggesting that lidocaine could be a potent alternative to opioids.

Eugenol (EUG) is a bioactive monoterpenoid used as an analgesic, preservative, and flavoring agent. Our new data show EUG as a voltage-gated Na
+ channel (VGSC) inhibitor, comparable but not identical to lidocaine (LID). EUG inhibits both total and only TTX-R voltage-activated Na+ currents (INa ) recorded from VGSCs naturally expressed on dorsal root ganglion sensory neurons in rats. Inhibition is quick, fully reversible, and dose-dependent. Our biophysical and pharmacological analyses showed that EUG and LID inhibit VGSCs with different mechanisms. EUG inhibits VGSCs with a dose–response relationship characterized by a Hill coefficient of 2, while this parameter for the inhibition by LID is 1. Furthermore, in a different way from LID, EUG modified the voltage dependence of both the VGSC activation and inactivation processes and the recovery from fast inactivated states and the entry to slow inactivated states. In addition, we suggest that EUG, but not LID, interacts with VGSC pre-open–closed states, according to our data. [ABSTRACT FROM AUTHOR]- Published

This study aimed to investigate the effects of opioid-free anesthesia (OFA) in laparoscopic gastrectomy and identify the psychological factors that could influence the efficacy of OFA. 120 patients undergoing laparoscopic gastrectomy were allocated to either the opioid-based anesthesia group (OA) (n = 60) or the OFA (n = 60) group. Remifentanil was administered to the OA group intraoperatively, whereas dexmedetomidine and lidocaine were administered to the OFA group. The interaction effect of the psychological factors on OFA was analyzed using the aligned rank transform for nonparametric factorial analyses. The opioid requirement for 24 h after surgery was lower in the OFA group than in the OA group (fentanyl equivalent dose 727 vs. 650 μg, p = 0.036). The effect of OFA was influenced by the pain catastrophizing scale (p = 0.041), temporal pain summation (p = 0.046), and pressure pain tolerance (p = 0.034). This indicates that patients with pain catastrophizing or high pain sensitivity significantly benefited from OFA, whereas patients without these characteristics did not. This study demonstrated that OFA with dexmedetomidine and lidocaine effectively reduced the postoperative 24-h opioid requirements following laparoscopic gastrectomy, which was modified by baseline pain catastrophizing and pain sensitivity. The study protocol was approved by the Institutional Review Board of Yonsei University Health System Gangnam Severance Hospital (#3–2021-0295) and registered at ClinicalTrials.gov (NCT05076903).

Background: Physical pain is highly prevalent and impacts the well-being of patients with advanced oncologic disease. Although myofascial pain syndrome (MPS) can be one of the components of pain in cancer patients on palliative care (PC), so far there is no evidence about the benefit of treatment with 1% lidocaine needling. Objectives: To evaluate the efficacy of MPS treatment with injection of 1% lidocaine on the reduction of pain in cancer patients on PC. Design: Single-blind randomized clinical trial. Subjects: Patients aged 50 years or older with end-stage cancer, admitted to a cancer ward or monitored during radiotherapy in three Brazilian hospitals, with a diagnosis of MPS with a pain intensity of five or more according to the Visual Analog Scale (VAS). The patients were divided into two groups: trigger point (TP) injection with 1% lidocaine and control. Measurements: Pain intensity was assessed with the VAS, pain threshold with an algometer, and the medications being used were determined before and 72 hours after the intervention. Results: Thirty patients (15 per group) were assessed. After 72 hours, there was a reduction in referred pain intensity (p < 0.001) and an increase in pressure threshold (p = 0.007) in the intervention group (IG), with no difference in the control. The frequency of individuals who reduced the doses and/or classes of pain medications was higher in the IG (p = 0.011). Conclusion: One percent lidocaine needling in TPs was an effective therapy for pain reduction in MPS. [ABSTRACT FROM AUTHOR]

Skull pin insertion causes hypertension and tachycardia that adversely affects cerebral hemodynamics. We compared the efficacy of sterile silicone studs (SS) and pin site infiltration with lidocaine in attenuation of the sympathetic response to skull pin insertion. Adult patients (N = 120) undergoing supratentorial craniotomy under general anesthesia were randomized to receive either medical-grade sterile SS or 2 mL of 2% plain lidocaine infiltration at each pin site. Hemodynamic (heart rate and mean arterial pressure) response to skull pin insertion at baseline and at 0, 1, 2, 3, and 5 minutes after skull pin insertion was compared. Requirement of rescue analgesia (fentanyl), complications such as pin-site bleeding, and surgeon satisfaction score were assessed. Heart rate in the lidocaine group was significantly greater at 0, 1, 2, 3, and 5 minutes after pin insertion compared with the SS group (P < 0.05). Mean arterial pressure was also significantly higher in the lidocaine group at 0, 1, 2, and 3 minutes after pin insertion (P = 0.001, P = 0.01, P = 0.034, and P = 0.042) compared with the SS group. The number of patients requiring fentanyl [17/60 (28.3%) vs. 40/60 (66%), P = 0.001] was lower in the SS group. The incidence of pin site bleeding was also lower in the SS group, and surgeon satisfaction score was greater. Sterile SS appear to be more effective than lidocaine infiltration in attenuating the hemodynamic response to skull pin insertion with minimal adverse effects. Further multicenter studies are necessary to conclusively establish the safety and efficacy of sterile SS. [ABSTRACT FROM AUTHOR]

CARBON paper , *CARBON fibers , *LIDOCAINE , *SCANNING electron microscopy , *DETECTORS - Abstract
A highly sensitive sensor based on carbon fiber paper modified with a shungite–copper formazanate composite is presented for the voltammetric determination of lidocaine. The synthesized organometallic complex, composite, and modified electrode are characterized by infrared spectroscopy, high-resolution mass spectrometry, elemental analysis, scanning electron microscopy, and cyclic and linear sweep voltammetry. The twofold increase in the current of the lidocaine oxidation peak on the modified electrode compared to the unmodified one is associated with the sensitizing effect of the composite modifier, which is due to an increase in the electroactive area and the number of lidocaine binding sites on the electrode surface. The sensor exhibits a wide dynamic range from 2 to 2120 µM with a low limit of detection of 0.18 µM lidocaine and high sensitivity of 0.755 µA/V µM. The interelectrode and intraelectrode repeatability of the analytical signal do not exceed 3.5%. The sensor response is stable within three weeks. The developed sensor was used for the determination of lidocaine in pharmaceuticals. The results of an analysis of real samples demonstrated good reproducibility (RSD ≤ 5.5%) and recovery (98–102%).

Background: This study aimed to compare two analgesic pretreatment techniques for assessing pain reduction before spinal needle insertion and the subsequent patient satisfaction levels in pregnant female patients undergoing cesarean sections. Methods: Sixty pregnant female patients scheduled for elective cesarean section under spinal anesthesia were randomly assigned to two groups. The Lidocaine group received local skin infiltration with 2% lidocaine pretreatment before spinal needle introducer insertion, whereas the eutectic mixture of local anesthetics (EMLA) group received EMLA (lidocaine 2.5% and prilocaine 2.5%) cream pretreatment for at least 30 min before spinal needle introducer insertion. Subjective and objective pain scores, procedure duration, number of attempts, maternal satisfaction, and decisions regarding future numbing procedures and regional anesthesia were assessed. Results: The demographic characteristics of the patients were similar between groups. The mean visual analogue scale pain score was significantly lower in the EMLA group compared to the lidocaine group (P < 0.05). Additionally, the objective pain score was significantly lower in the EMLA group (P < 0.05). The duration of spinal block placement was significantly longer in the lidocaine group than in the EMLA group (P < 0.05). The number of attempts to perform the spinal block placement was similar in both groups. However, women in the EMLA group expressed greater overall satisfaction than those in the lidocaine group (76.7% vs. 20.0%, P < 0.05). Conclusions: Analgesic pretreatment with EMLA cream is superior to local skin infiltration with lidocaine in pregnant patients undergoing elective cesarean section under spinal anesthesia.

Background and Aims: Opioid-sparing analgesia for acute postoperative pain after breast cancer surgery is crucial due to opioid-related side effects. The utilisation of erector spinae plane block and low-dose intravenous ketamine-dexmedetomidine are widely recognised as non-opioid analgesic methodologies. The objective of this study was to conduct a randomised trial to examine the analgesic efficacy of both approaches while minimising the use of opioids. Methods: Seventy-two female patients scheduled for unilateral modified radical mastectomy were recruited. They were allocated randomly to Group ESPB, which received ipsilateral ultrasound-guided erector spinae plane block by 20 mL bupivacaine 0.5% at the level of T5 after induction of general anaesthesia, and Group Ket-Dex, which received intravenous (IV) bolus 0.25 mg/kg of ketamine and 0.5 µg/kg of dexmedetomidine, followed by an IV infusion of 0.25 mg/kg of ketamine and 0.3 µg/kg of dexmedetomidine per hour. Total postoperative morphine consumption (24 h) was the primary outcome. The secondary outcomes were pain scores over 24 hours during rest, duration of analgesia, isoflurane consumption, time to awakening, postoperative nausea and vomiting (PONV), and postoperative serum cortisol level. Results: The postoperative morphine consumption over 24-hour in Group ESPB was 3.26 mg (0-6.74) versus 2.35 mg (2.08-4.88) in Group Ket-Dex (P = 0.046). Group Ket-Dex had lower pain scores at rest, longer analgesia duration, longer awakening time, and lower postoperative serum cortisol levels. Conclusion: Intravenous low-dose ketamine-dexmedetomidine infusion intraoperatively with inhalational-based general anaesthesia provides superior opioid-sparing analgesia to that of ESPB in patients undergoing unilateral non-reconstructive modified radical mastectomy, with less postoperative opioid consumption and stress response.

OBJECTIVE: This study aimed to compare the effects of low-dose subarachnoid injections of 2% lidocaine (LIDO) and 0.5% bupivacaine (BUPI) in goats. ANIMALS: 6 healthy, privately owned female goats. METHODS In this randomized blind crossover clinical trial, each goat received 0.05 mL/kg-1 of LIDO, BUPI, or sterile saline solution into the lumbosacral subarachnoid space, with a seven-day washout. Cardiorespiratory variables, rectal temperature, and somatosensory (pinprick) and motor (ataxia) functions were recorded at baseline (time 0) and 2, 5, 10, 15, and 30 minutes after injection, then every 20 minutes until the goat was standing and able to walk. Time to regain somatosensory and motor functions was compared between treatments using Kaplan-Meier survival curves and the Cox proportional hazards model. Linear mixed-effects models were used to compare cardiorespiratory variables between treatments and over time. A P value ≤ .05 was considered significant. RESULTS: Somatosensory recovery was longer with BUPI, though not statistically significant. The median time to stand was 50 (50, 67) minutes after LIDO injection and 104 (101, 156) minutes after BUPI injection (P = .031). The median time to walk was 72 (54, 85) minutes after LIDO versus 225 (220, 245) minutes after BUPI injection (P = .031). Cardiovascular and respiratory variables showed no significant differences between treatments. CLINICAL RELEVANCE: Despite prolonged ataxia with BUPI, pinprick sensation recovery did not differ. At reduced doses, both LIDO and BUPI are deemed acceptable for short procedures of the flank, pelvic limb, or tail in healthy goats. [ABSTRACT FROM AUTHOR]

Objectives: To compare the tensile strength of fast absorbable Polyglactin 910 suture material when impregnated with various agents for local anesthesia and to investigate whether the presence of ethanol in Xylocaine spray could explain a potential reduction in tensile strength after use of Xylocaine spray. Methods: In all, 120 suture samples of Polyglactin 910 were divided into four groups of 30. These four groups were randomly impregnated with isotonic sodium chloride, isotonic sodium chloride plus Xylocaine spray, isotonic sodium chloride plus Xylocaine gel, or isotonic sodium chloride plus ethanol. After impregnation, the sutures were stored in sealed glass tubes in a heating cabinet at 37°C for 72 h. Thereafter, the tensile strength of these 120 samples was assessed by a universal tensile testing machine. The maximal force needed to break the suture material was recorded in newtons (N). Results: Fast absorbable Polyglactin 910 suture material impregnated with Xylocaine spray or ethanol showed weakened tensile strength (mean values 11.40 and 11.86 N, respectively), whereas the specimens impregnated with Xylocaine gel or sodium chloride retained their tensile strength better (mean values 13.81 and 13.28 N, respectively; mean difference between Xylocaine gel and Xylocaine spray −2.41 N, P < 0.001). Conclusion: In this in vitro experiment, ethanol and Xylocaine spray weakened the tensile strength of fast absorbable Polyglactin 910 sutures. Use of Xylocaine spray, which contains ethanol, for local anesthesia might lead to early breakdown of the suture material and wound rupture. The authors suggest caution when using Xylocaine spray in combination with fast absorbable Polyglactin 910 suture. Synopsis: This in vitro experiment shows that Xylocaine spray containing ethanol can decrease the tensile strength of the suture material, leading to early suture breakage. [ABSTRACT FROM AUTHOR]

POSTOPERATIVE pain , *VISUAL analog scale , *OPERATIVE surgery , *LIDOCAINE , *PAIN management - Abstract
Being one of the most common abdominal surgical procedures, numerous techniques have been adapted to decrease post-operative pain post cholecystectomy. However, the efficacy of intravenous (IV) lidocaine in managing post operative pain after LC is still controversial, according to many recent studies. This study aims to detect the effectiveness of IV lidocaine compared to other medications in managing postoperative pain. PubMed, Scopes, Web of Science and Cochrane Library were searched for eligible studies from inception to June 2023, and a systematic review and meta-analysis was done. According to eligibility criteria, 14 studies (898 patients) were included in our study. The pooled results of the included studies showed that the pain score after 6, 12 and 24 h after the surgery was significantly lower in those who received IV lidocaine as a painkiller (Visual Analogue Scale [VAS] 6H, mean difference [MD] = −1.20, 95% confidence interval [CI] = −2.20, −0.20, P = 0.02; I² = 98%, VAS 12H, MD = −0.90, 95% CI = −1.52, −0.29, P = 0.004; I² = 96% and VAS 24H, MD = −0.86, 95% CI = −1.48, −0.24, P = 0.007; I² = 92%). In addition, IV lidocaine is associated with a significant decrease in the opioid requirement after the surgery (opioid requirements, MD = −29.53, 95% CI = −55.41, −3.66, P = 0.03; I² = 98%). However, there was no statistically significant difference in the incidence of nausea and vomiting after the surgery between the two groups (nausea and vomiting, relative risk = 0.91, 95% CI = 0.57, 1.45, P = 0.69; I² = 50%). Lidocaine infusion in LC is associated with a significant decrease in post operative pain and in opioid requirements after the surgery. [ABSTRACT FROM AUTHOR]

Introduction: In hemodialysis patients, pain associated with needle insertion into an arteriovenous fistula is a physical and psychological problem. The aim of this study was to assess the effectiveness of pre‐puncture application of an ice pack, EMLA cream, or lidocaine spray to reduce pain associated with access puncture. Methods: This was a multicenter study done in nine hemodialysis centers in Iraq. The study utilized a randomized, parallel‐group design, in which patients being dialyzed using an arteriovenous access were allocated into one of four groups. Access puncture was preceded by nothing (control group), by use of ice pack cooling at the puncture site, by application of EMLA cream, or by application of lidocaine spray. Pain after access puncture was assessed during a single treatment for each patient. Pain was quantified using a Visual Analogue Scale. Findings: A total of 1548 patients agreed to participate, and 1041 patients were included in the data analysis. Use of an ice pack, EMLA cream, or lidocaine spray each was associated with a lower pain score on access puncture compared with no pretreatment. The mean Visual Analogue Scores in the four groups were: 69.7 ± 15.7 in the controls, 39.8 ± 13.2 in the ice pack group, 45 ± 18.4 in the EMLA group, and 52.9 ± 15.2 in lidocaine group. Ranking of the pain severity scores suggested that ice pack use was associated with the least pain, followed by use of EMLA cream and use of lidocaine spray (severity score ranking, from lowest to highest, being 1.62, 2.18, and 2.63, respectively). Discussion: Application of an ice pack prior to vascular access puncture is a fast and inexpensive technique to limit pain associated with this procedure. [ABSTRACT FROM AUTHOR]

Background Transforaminal epidural steroid injections (TFESI) are commonly employed to treat lumbosacral radiculopathy. Despite anti-inflammatory properties, the addition of 3% hypertonic saline has not been studied. Objective Compare the effectiveness of adding 0.9% NaCl (N-group) vs. 3% NaCl (H-group) in TFESI performed for lumbosacral radiculopathy. Methods This retrospective study compared TFESI performed with lidocaine, triamcinolone and 0.9% NaCl vs. lidocaine, triamcinolone and 3% NaCl. The primary outcome was the proportion of patients who experienced a ≥ 30% reduction in pain on a verbal rating scale (VRS; 0–100) at 3 months. Secondary outcome measures included the proportion of patients who improved by at least 30% for pain at 1 and 6 months, and who experienced ≥15% from baseline on the Oswestry disability index (ODI) at follow-up. Results The H-group experienced more successful pain outcomes than the N-group at 3 months (59.09% vs. 41.51%; P = .002) but not at 1 month (67.53% vs. 64.78%; P = .61) or 6 months (27.13% vs 21.55%: P = .31). For functional outcome, there was a higher proportion of responders in the H-group than the N-group at 3 months (70.31% vs. 53.46%; P = .002). Female, age ≤ 60 years, and duration of pain ≤ 6 months were associated with superior outcomes at the 3-month endpoint. Although those with a herniated disc experienced better outcomes in general with TFESI, the only difference favoring the H-group was for spondylolisthesis patients. Conclusions 3% hypertonic saline is a viable alternative to normal saline as an adjunct for TFESI, with randomized studies needed to compare its effectiveness to steroids as a possible alternative.

Background: Chronic abdominal pain in children is occasionally caused by anterior cutaneous nerve entrapment syndrome (ACNES). Diagnosing and treating this typical peripheral abdominal wall neuropathy is challenging. Management usually starts with minimally invasive tender point injections. Nevertheless, these injections can be burdensome and might even be refused by children or their parents. However, a surgical neurectomy is far more invasive. Treatment with a Lidocaine 5% medicated patch is successfully used in a variety of peripheral neuropathies. Aims: This single center retrospective case series aimed to evaluate the effectiveness and tolerability of lidocaine patches in children with ACNES. Methods: Children aged under 18 diagnosed with ACNES who were treated with a 10 day lidocaine patch treatment between December 2021 and December 2022 were studied. Patient record files were used to collect treatment outcomes including pain reduction based on NRS and complications. Results: Twelve of sixteen children (mean age 13 years; F:M ratio 3:1) diagnosed with ACNES started the lidocaine patch treatment. Two patients achieved a pain free status and remained pain free during a 4 and 7 months follow‐up. A third child reported a lasting pain reduction, but discontinued treatment due to a temporary local skin rash. Five additional patients reported pain reduction only during application of the patch. The remaining four children experienced no pain relief. No adverse effects were reported. Conclusion: Lidocaine patches provides pain relief in a substantial portion of children with ACNES.

Tramadol and remifentanil, which is an opioid analgesic are known to have a local anesthetic effect and the present study aimed to evaluate the local anesthetic efficacy of them on twenty-five adult male rabbits Oryctolagus cuniculus (aged between 10-12 months and weighing 1.5±0.08g) who were divided into five groups received the following treatment subcutaneously for 5 days; G1: 5% Tramadol 15 mg/kg BW; G2: 2% Remifentanil 2 mg/kg BW; G3: 2% Lidocaine 4 mg/kg BW; G4: 2% Remifentanil with epinephrine 0.00l mg/kg BW; and G5:2% Remifentanil with Carbopol gel 2 mg/kg BW. Baseline, pre-anesthetic, and post-anesthetic physiological parameters, including temperature, respiratory rate, and heart rate, were meticulously recorded for all groups following local administration of lidocaine, tramadol, and remifentanil. The results showed that tramadol caused a significant decrease in the temperature while other groups showed non-significant effect, results also revealed that pain evaluation that performed according to Grimace Scale scores and by the behavioral analysis of pain assessment elucidated that Lidocaine treatment group showed a statistically significant lower pain response compared to the Tramadol and Remifentanil groups and further significant improvement in pain were observed with the addition of epinephrine or Carbopol gel to Remifentanil. Both combinations resulted in a statistically significant decrease in pain parameters for all measured features comparing with Tramadol and Remifentanil groups and these results leads to conclude that tramadol and remifentanil showed a comparable anaesthetic effect that improved significantly with epinephrine or carbopol gel as local anaesthetics that may surpass lidocaine local anaesthetic effect significantly.
