lidocaine infusions

PURPOSE: This study was performed to evaluate the effects of intraoperative intravenous lidocaine on postoperative delirium in elderly patients with hip fracture. PATIENTS AND METHODS: In total, 100 elderly patients undergoing hip fracture surgery were randomized to the lidocaine group (Group L) or saline (control) group (Group C). Before anesthetic induction, Group L received lidocaine at 1 mg/kg for more than 10 minutes followed by continuous infusion at 1.5 mg/kg/h until the end of surgery...

BACKGROUND: Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is an invasive procedure that required deep sedation to suppress coughing and body movements. Deep sedation, on the other hand, has been shown to cause respiratory and circulatory depression, especially when the airway is shared with the endoscopist. Esketamine is a novel sedative and analgesic with little respiratory inhibition that appears to be an appropriate adjuvant in propofol sedation for EBUS-TBNA...

Cancer-related pain is one of the most common and incapacitating symptoms for cancer patients. Cancer pain can be caused by diagnostic or therapeutic procedures, side effects and toxicity from therapy, or the cancer itself. Uncontrolled cancer-related pain is associated with inadequate quality of life and reduced functional status. Optimal pain management during the perioperative period requires a tailored approach. Interventions that are recommended for the management of acute surgical pain include regional anesthesia, local anesthetic infusions, non-opioid analgesics (ketamine, dexmedetomidine, lidocaine, and non-steroidal anti-inflammatory drugs), and opioids...

BACKGROUND: The application of enhanced recovery after surgery principles decreases postoperative complications (POCs), length of stay (LOS), and readmissions. Pharmacoprophylaxis decreases morbidity, but the effect of specific regimens on clinical outcomes is unclear. METHODS AND MATERIALS: Records of 476 randomly selected adult patients who underwent elective colorectal surgeries (ECRS) at 10 US hospitals were abstracted. Primary outcomes were surgical site infection (SSI), venous thromboembolism (VTE), postoperative nausea and vomiting (PONV), pain, and ileus rates...

Pain experience is affected by both ascending nociceptive signals and descending modulation. Expectations can affect pain experience and augment treatment-induced analgesia through descending inhibitory modulation of pain. This open-label, prospective cohort study examined the association between participant expectation ratings and pain reduction in adult participants with chronic pain receiving an intravenous lidocaine infusion. We aimed to explore whether: 1) participants' expectations of treatment efficacy were associated with pain reduction over 8 weeks after infusion; and 2) participants' therapeutic alliance was associated with expectations and/or pain reduction...

PURPOSE: The aim of this project was to investigate whether opioid pain scores, postoperative opioid requirements, and postanesthesia care unit (PACU) length of stay were impacted when comparing a 24-hour intravenous lidocaine infusion versus postoperative discontinuation of the lidocaine infusion. DESIGN: A retrospective chart review was used both before and after the discontinuation of postoperative lidocaine infusions for a quality improvement project. METHODS: The project was carried out in the adult surgery PACU setting at a level 1 trauma center between April 2021 and September 2021...

BACKGROUND AND AIMS: This prospective randomized study designed to evaluate the efficacy of dexmedetomidine either added to LA mixture or administered IV during subtenon block for cataract surgery. MATERIAL AND METHODS: 75 patients, undergoing cataract surgery with subtenon anesthesia, were assigned randomly into three equal groups, Group I received subtenon bupivacaine 0.5% (1 ml) + lidocaine 2% (1 ml) + saline 0.9% (0.5 ml) and IV infusion of normal saline. Group II received subtenon bupivacaine 0...

INTRODUCTION: Complex regional pain syndrome (CRPS) is characterized by extreme pain in a limb disproportional to the clinical history or physical findings accompanied by the signs of autonomic dysfunction. The pathophysiology of CRPS is obscure, making it challenging to treat. Treatment options include medications, physical therapy, and psychological support. In some cases, surgery or other minimally-invasive procedures such as nerve blocks may be recommended, while several novel treatments, such as ozone therapy, lack sufficient clinical evidence...

BACKGROUND: The semi-automatic intraosseous device (EZ-IO®) is useful for safely securing intraosseous access. There are some complications associated with its use but few studies have examined the risk factors. The present study aimed to investigate the risk factors for extravasation as a complication of EZ-IO use in pediatric patients. METHODS: This study is a secondary analysis of a previous, monocentric, retrospective study conducted in Japan describing the use of EZ-IO in a pediatric emergency department...

The protocol here provides a simple, highly replicable methodology to induce in situ acute regional myocardial ischemia in the rabbit for non-survival and survival experiments. New Zealand White adult rabbit is sedated with atropine, acepromazine, butorphanol, and isoflurane. The animal is intubated and placed on mechanical ventilation. An intravenous catheter is inserted into the marginal ear vein for the infusion of medications. The animal is pre-medicated with heparin, lidocaine, and lactated Ringer's solution...

BACKGROUND: Intractable postherpetic neuralgia (PHN) can be difficult to manage even with aggressive multimodal therapies. Patients who experience uncontrolled refractory cranial PHN despite conservative treatment may benefit from an intrathecal drug delivery system (IDDS). For craniofacial neuropathic pain, the traditional approach has been to place the intrathecal catheter tip below the level of the cranial nerve root entry zones, which may lead to insufficient analgesia. CASE SUMMARY: We describe a 69-year-old man with a 1-year history of PHN after developing a vesicular rash in the ophthalmic division of cranial nerve V (trigeminal nerve) distribution...

OBJECTIVE: Multiple organ failure can occur as a result of postoperative complications. Research has indicated that the underlying mechanism of organ dysfunction is a microcirculation disorder. Because of its antioxidant and anti-inflammatory properties, lidocaine has the potential to improve microvascular blood flow. This study was performed to assess the effect of intraoperative intravenous lidocaine infusion on the microcirculation and determine the incidence of postoperative complications...

Myoclonus is a known side effect of propofol and can interfere with surgery and possibly precipitate patient injury. Here, we report a 23-year-old patient undergoing an L5 osteoblastoma resection with a predominantly propofol-based anaesthetic who developed intra-operative myoclonus. Other adjuncts included ketamine, lidocaine and fentanyl infusions. The myoclonus did not improve after deepening the anaesthetic with propofol, opioid boluses or discontinuation of the lidocaine infusion. The myoclonus ceased after reducing the propofol infusion and increasing the ketamine and opioid infusions...

MATERIALS AND METHODS: This study included 135 buffaloes examined at Dakahlia Governorate between 2011 and 2022 suffering from various surgical salivary affections. The recorded surgical affections had salivary fistula (n = 44), ectasia of Stenson's duct (n = 11), ranula/mucocele (n = 46), and cervical sialocele (n = 34)...

Background: Infusions with lidocaine or ketamine have been separately established in the treatment of chronic pain. This study aims to retrospectively evaluate the effect of combined infusions of lidocaine and ketamine. Materials & methods: Patient records were screened for receipt of combined ambulatory infusions of lidocaine and ketamine from 2012 through 2021. A scoring system was designed to assess pain response retrospectively. Results: A total of 319 patients were included. Median pain reduction in days was 10...

Surgery is one of the most frequent and effective intervention strategies for lumbar spinal stenosis, however, one-third of patients are not satisfied with postoperative outcomes. It is not clear whether perioperative systemic lidocaine could accelerate the early postoperative quality of recovery in patients undergoing lumbar spinal stenosis surgery. 66 patients were enrolled in this trial. Lidocaine or placebo was administered at a loading dose of 1.5 mg/kg for 10 min and then infused at 2.0 mg/kg/hour till the end of surgery...

Introduction: Thermal injury to recurrent laryngeal nerve (RLN) during radiofrequency ablation (RFA) can produce temporary or permanent vocal cord paralysis.1 Hydrodissection with cold 5% glucose of "danger triangle" protects RLN during RFA.2 When RFA is performed under local anesthesia, RLN function is monitored by patients producing vocal sounds.3 Large lesions requiring longer RFAs warrant general sedation where voice cannot be assessed, therefore, an additional technique for RLN protection is advisable...

Perioperative lidocaine (lignocaine) infusions are being employed with increasing frequency. The determinants of systemic lidocaine concentrations during prolonged administration are unclear. In the Long-term Outcomes after Lidocaine Infusions for PostOperative Pain (LOLIPOP) pilot trial, the impact of infusion duration and body size metrics on serum lidocaine concentrations was examined with regression models in 48 women undergoing breast cancer surgery. Lidocaine was delivered as an intravenous bolus (1.5 mg/kg) and infusion (2 mg/kg per h) intraoperatively, followed by a 12-h subcutaneous infusion (1...

BACKGROUND: It has been proposed that dose reduction via co-administration of other agents might ameliorate respiratory depression associated with ketofol. AIMS: The present study was designed to evaluate the effects of adding lidocaine, fentanyl, or dexmedetomidine on the required dose and cardiorespiratory variables in dogs undergoing total intravenous anesthesia (TIVA) with ketofol. METHODS: In phase I, twelve dogs (six per each treatment) were induced and maintained with two out of four anesthetic regimens of (1) ketofol (4 mg/kg and 0...
