Project description:PurposeMany patients develop severe and persistent pain after hepatectomy delaying postoperative rehabilitation. Studies have suggested that intravenous lidocaine infusion relieved postoperative pain and improved overall postoperative outcomes. However, its efficacy on hepatectomy is still masked, due to the postoperative metabolic change of lidocaine by the liver. We hypothesized that intravenous lidocaine infusion in the perioperative period would lead to postoperative pain reduction and improve the overall patient experience.Study design and methodsIn this prospective double-blind, randomized controlled design trial, 260 adults scheduled for hepatectomy will be allocated to the lidocaine and the placebo groups. The lidocaine group will be administered lidocaine intravenously during intraoperative period and 72 postoperative hours; the placebo group will be administered normal saline at the same volume, infusion rate, and timing. The primary outcome is the incidence of moderate-severe pain (numeric rating scale ≥4) during movement at 24 hours after surgery. The secondary outcomes include the incidence of moderate-severe pain at 24 hours after surgery at rest, the incidence of moderate-severe pain at 48 and 72 hours after surgery at rest and during movement, the cumulative morphine consumption at 24, 48 and 72 hours postoperatively, bowel function recovery, the incidence of postoperative nausea and vomiting, the incidence of postoperative pulmonary complications, the length of hospital stay, levels of inflammatory factors and patient satisfaction scores.DiscussionThis is the first prospective trial to shed light on the efficacy of intraoperative period and 72 postoperative hours intravenous lidocaine on postoperative pain and recovery after hepatectomy. The findings will provide a new strategy of perioperative pain management for hepatectomy.

Project description:BackgroundIntravenous lidocaine infusion is known to reduce postoperative pain for days or weeks beyond the infusion time, and plasma half-life in several types of surgical procedures.ObjectivesTo evaluate the effect of intravenous (IV) lidocaine infusion on long term postoperative pain intensity for 3 months in patients undergoing spinal fusion surgery.Study designProspective randomized, double-blinded study.SettingAssiut University Hospital, Assiut, Egypt.MethodsForty patients undergoing spinal fusion surgery were randomized into 2 equal groups (n = 20 in each). Patients in the lidocaine group received IV lidocaine at a dosage of 2.0 mg/kg slowly before induction of anesthesia, followed by lidocaine IV infusion at a rate of 3.0 mg/kg/h until the end of surgery. Patients in the control group received an equal volume of normal saline. The following data were assessed: pain by Visual Analog Score (VAS) at 1 hour, 6 hours, 12 hours, 24 hours, 48 hours, at discharge time, and at 1 month, 2 months, and 3 months post-operation, time to first request for additional analgesia, and total morphine consumption in 24 hours.ResultsLidocaine significantly reduced the postoperative pain score (VAS) for up to 3 months (P < .05), and significantly reduced morphine consumption (4.5 mg vs. 19.85 mg) in the 1st 24 hours postoperative. Lidocaine also significantly, prolonged (P < .05) the time to first request for additional analgesia (9.56 ± 2.06 hours vs 1.82 ± 0.91 hours).ConclusionIntra-operative lidocaine, when given intravenously as a bolus followed by an infusion, significantly decreased long term postoperative back pain intensity in patients undergoing spinal fusion surgery.

Project description:BackgroundPain, including associated pain management, remains a burden on patients after thoracic surgery. Our objective was to investigate whether perioperative intravenous administration of lidocaine reduces postoperative morphine consumption and pain intensity after video-assisted thoracoscopic surgery (VATS).MethodsIn this double-blind, placebo-controlled superiority trial, patients undergoing VATS with a planned duration of ≤90 minutes were randomized within an intention-to-treat setting. Patients received either intravenous lidocaine or placebo as a bolus of 1.5 mg/kg 30 minutes before incision, followed by a continuous infusion of 3.0 mg/kg/hour until 2 hours after skin closure. Pain and morphine consumption were evaluated when resting and when coughing 1, 2, 4, 8, 16, 24, and 48 hours after skin closure and in a follow-up 14, 90, and 180 days postoperatively.ResultsTwenty-eight patients were included in the lidocaine group, 24 in the placebo group. Patients' characteristics and preoperative pain scores were similar in both groups. When coughing, patients of the lidocaine group had less pain within 24 hours after skin closure than the placebo group (4.60±1.64 vs. 5.52±1.65; P=0.02). Morphine consumption was not statistically significantly lower in lidocaine group (18.22±12.87 vs. 21.26±9.39 mg; P=0.26). There were no significant differences between groups in secondary outcomes.ConclusionsOur results suggest that perioperative intravenous lidocaine administration reduces pain scores after VATS. The beneficial clinical effects are limited. Nevertheless, intravenous lidocaine may be helpful as part of a multimodal analgesia protocol or with patients in whom the use of other analgesics is contraindicated.Trial registrationClinicalTrials.gov NCT03677817.

Project description:IntroductionPostoperative pulmonary complications (PPCs) are the most common complications following thoracoscopic surgery, resulting in increased hospital costs and perioperative mortality. Studies have shown that intravenous lidocaine infusion can exert its anti-inflammatory properties by reducing the release of proinflammatory cytokines. This study is designed to investigate whether intraoperative intravenous lidocaine infusion can reduce the incidence of PPCs in adult patients undergoing video-assisted thoracoscopic lung resection surgery.Methods and analysisThis single-centre, double-blinded study will enrol 366 patients scheduled for video-assisted thoracoscopic lung resection surgery. Patients will be randomly assigned to the lidocaine or placebo infusion group in a 1: 1 ratio. The lidocaine group will receive lidocaine intravenously during the intraoperative period, while the placebo group will be administered normal saline at an equal volume, infusion rate and timing. The primary outcome is the incidence of PPCs within 7 days following surgery. The secondary outcomes are quality of postoperative recovery 40 scores; length of hospital stay (determined by the number of days from admission to discharge); incidence of moderate to severe pain within 24 and 48 hours at rest and when coughing; incidence of additional rescue analgesics use and incidence of adverse events.Ethics and disseminationThe study was reviewed and approved by the Ethics Committee of Sichuan Provincial People's Hospital (approval no. 20222241). Written informed consent will be obtained from all patients before randomisation. The results of this trial will be disseminated in a peer-reviewed journal.Trial registration numberChiCTR2200061979.

Project description:IntroductionThe transition of acute to chronic postoperative pain (CPP) remains a significant burden to the rehabilitation of patients. The research for adjuvants to prevent CPP continues; among others, dexmedetomidine and lidocaine seem promising agents.MethodsThis is a long-term follow-up of a randomized, placebo-controlled, double-blind study on women who underwent open abdominal gynecological surgery and received dexmedetomidine or lidocaine or placebo infusion perioperatively (n = 81). The effect of these adjuvants on the development of CPP and neuropathic pain was assessed during a 12-month follow-up. Eighty-one (81) women ASA I-II, aged between 30 and 70 years, were randomly assigned to receive either dexmedetomidine (DEX group) or lidocaine (LIDO group) or placebo (CONTROL group) perioperatively. Before anesthesia induction, all patients received a loading intravenous dose of either 0.6 μg/kg dexmedetomidine or 1.5 mg/kg lidocaine or placebo, followed by 0.6 μg/kg/h dexmedetomidine or 1.5 mg/kg/h lidocaine or placebo until last suture. Patients were followed up to obtain the long-term outcomes at 3, 6, and 12 months. At these time-points, pain intensity was assessed with the Numerical Rating Scale, (NRS: 0-10) and the development of neuropathic elements with the Douleur Neuropathique 4 (DN4) score. Prognostic parameters that could affect chronic pain and its components were also identified.ResultsData from 74 women were analyzed. Dexmedetomidine significantly reduced NRS scores comparing to placebo at 3 months (p = 0.018), while at 6 months, lidocaine was found superior to placebo (p = 0.02), but not to dexmedetomidine, in preventing neuropathic pain (DN4 < 4). Regarding secondary endpoints, higher NRS cough scores at 48 h were associated with statistically significant NRS and DN4 scores at 3, 6, and 12 months (p < 0.02). At 6 months, a statistically significant correlation was also found between higher NRS values and older age (p = 0.020).ConclusionsDexmedetomidine was superior to placebo regarding the duration and severity of CPP, while lidocaine exhibited a protective effect against neuropathic elements of CPP.Trial registrationClinicalTrials.gov identifier, NCT03363425.

Project description:PurposeWe designed this study to evaluate the impact of intraoperative intravenous lidocaine infusion on postoperative opioid consumption after laparoscopic cholecystectomy.MethodsIn total, 98 patients scheduled for elective laparoscopic cholecystectomy were included and randomized. In the experimental group, intravenous lidocaine (bolus 1.5 mg/kg and continuous infusion 2 mg/kg/h) was administered intraoperatively additionally to the standard analgesia, whereas the control group received a matching placebo. Blinding existed at the level of both the patient and the investigator.ResultsOur study failed to confirm any benefit in opioid consumption, during the postoperative period. Lidocaine resulted to reduced intraoperative systolic, diastolic, and mean arterial pressure. Lidocaine administration did not change postoperative pain scores or the incidence of shoulder pain, at any time endpoint. Moreover, we did not identify any difference in terms of postoperative sedation levels and nausea rates.ConclusionOverall, lidocaine did not have any effect on postoperative analgesia after laparoscopic cholecystectomy.

Project description:IntroductionIntravenous lignocaine is an amide local anaesthetic known for its analgesic, antihyperalgesic and anti-inflammatory properties. Administration of intravenous lignocaine has been shown to enhance perioperative recovery parameters. This is the protocol for a systematic review which intends to summarise the evidence base for perioperative intravenous lignocaine administration in patients undergoing spinal surgery.Methods and analysisOur primary outcomes include: postoperative pain scores at rest and movement at predefined early, intermediate and late time points and adverse events. Other outcomes of interest include perioperative opioid consumption, composite morbidity, surgical complications and hospital length of stay. We will include randomised controlled trials, which compared intravenous lignocaine infusion vs standard treatment for perioperative analgesia. We will search electronic databases from inception to present; MEDLINE, EMBASE and Cochrane Library (Cochrane Database of Systematic Reviews and CENTRAL). Two team members will independently screen all citations, full-text articles and abstract data. The individual study risk of bias will be appraised using the Cochrane risk of bias tool. We will obtain a risk ratio or mean difference (MD) from the intervention and control group event rates based on the nature of data. We will correct for the variable measurement tools by using the standardised MD (SMD). We will use a random-effects model to synthesise data. We will conduct five subgroup analysis: major versus minor surgery, emergency versus elective surgery, patients with chronic pain conditions versus patients without, duration of lignocaine infusion and adult versus paediatric. Confidence in cumulative evidence for will be classified according to the Grading of Recommendations, Assessment, Development and Evaluation system. We will construct summary of findings tables supported detailed evidence profile tables for predefined outcomes.Ethics and disseminationFormal ethical approval is not required as primary data will not be collected. The results will be disseminated through a peer-reviewed publication.Prospero registration numberCRD420201963314.

Project description:Cancer is a major global health problem and the second leading cause of death worldwide. When detected early, surgery provides a potentially curative intervention for many solid organ tumours. Unfortunately, cancer frequently recurs postoperatively. Evidence from laboratory and retrospective clinical studies suggests that the choice of anaesthetic and analgesic agents used perioperatively may influence the activity of residual cancer cells and thus affect subsequent recurrence risk. The amide local anaesthetic lidocaine has a well-established role in perioperative therapeutics, whether used systemically as an analgesic agent or in the provision of regional anaesthesia. Under laboratory conditions, lidocaine has been shown to inhibit cancer cell behaviour and exerts beneficial effects on components of the inflammatory and immune responses which are known to affect cancer biology. These findings raise the possibility that lidocaine administered perioperatively as a safe and inexpensive intravenous infusion may provide significant benefits in terms of long term cancer outcomes. However, despite the volume of promising laboratory data, robust prospective clinical evidence supporting beneficial anti-cancer effects of perioperative lidocaine treatment is lacking, although trials are planned to address this. This review provides a state of the art summary of the current knowledge base and recent advances regarding perioperative lidocaine therapy, its biological effects and influence on postoperative cancer outcomes.

Project description:IntroductionPostoperative delirium is a frequent adverse event following elective non-cardiac surgery. The occurrence of delirium increases the risk of functional impairment, placement to facilities other than home after discharge, cognitive impairment at discharge, as well as in-hospital and possibly long-term mortality. Unfortunately, there is a dearth of effective strategies to minimise the risk from modifiable risk factors, including postoperative pain control and the analgesic regimen. Use of potent opioids, currently the backbone of postoperative pain control, alters cognition and has been associated with an increased risk of postoperative delirium. Literature supports the intraoperative use of lidocaine infusions to decrease postoperative opioid requirements, however, whether the use of postoperative lidocaine infusions is associated with lower opioid requirements and subsequently a reduction in postoperative delirium has not been investigated.Methods and analysisThe Lidocaine Infusion for the Management of Postoperative Pain and Delirium trial is a randomised, double-blinded study of a postoperative 48-hour infusion of lidocaine at 1.33 mg/kg/hour versus placebo in older patients undergoing major reconstructive spinal surgery at the University of California, San Francisco. Our primary outcome is incident delirium measured daily by the Confusion Assessment Method in the first three postoperative days. Secondary outcomes include delirium severity, changes in cognition, pain scores, opioid use, incidence of opioid related side effects and functional benefits including time to discharge and improved recovery from surgery. Lidocaine safety will be assessed with daily screening questionnaires and lidocaine plasma levels.Ethics and disseminationThis study protocol has been approved by the ethics board at the University of California, San Francisco. The results of this study will be published in a peer-review journal and presented at national conferences as poster or oral presentations. Participants wishing to know the results of this study will be contacted directly on data publication.Trial registration numberNCT05010148.
