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:Intravenous 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.To evaluate the effect of intravenous (IV) lidocaine infusion on long term postoperative pain intensity for 3 months in patients undergoing spinal fusion surgery.Prospective randomized, double-blinded study.Assiut University Hospital, Assiut, Egypt.Forty 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.Lidocaine 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).Intra-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: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.

Project description:Despite the laparoscopic approach becoming the standard in colorectal surgery, postoperative pain management for minimally invasive surgery is still mainly based on strategies that have been established for open surgical procedures. Patient-controlled epidural and intravenous analgesia are considered standard postoperative analgesia regimens in colorectal surgery. Epidural analgesia provides excellent analgesia, but is increasingly scrutinized in laparoscopic surgery since postoperative pain after the laparoscopic approach is significantly reduced. Moreover, epidural analgesia can be associated with numerous complications. Therefore, epidural analgesia is no longer recommended for the management of postoperative pain in laparoscopic colorectal surgery. Likewise, patient-controlled intravenous analgesia is subject to significant side effects. Given these important limitations of the traditional strategies for postoperative analgesia, effective and efficient alternatives in patients undergoing laparoscopic colorectal surgery are needed. Both the transversus abdominis plane block and systemically administered lidocaine have already been reported to effectively reduce pain after laparoscopic colorectal surgery. We hypothesize that the transversus abdominis plane block is superior to perioperative intravenous lidocaine.One hundred and twenty five patients undergoing laparoscopic colorectal surgery will be included in this prospective, randomized, double-blind controlled clinical trial. Patients will be randomly allocated to three different postoperative strategies: postoperative patient-controlled intravenous analgesia with morphine (control group, n = 25), a transversus abdominis plane block with ropivacaine 0.375% at the end of surgery plus postoperative patient-controlled intravenous analgesia with morphine (TAP group, n = 50), or perioperative intravenous lidocaine plus postoperative patient-controlled intravenous analgesia with morphine (LIDO group, n = 50). As the primary outcome parameter, we will evaluate the opioid consumption during the first 24 postoperative hours. Secondary endpoints include the Numeric Rating Scale, time to return of intestinal function, time to mobilization, inflammatory response, incidence of postoperative nausea and vomiting, length of hospital stay and postoperative morbidity as assessed with the Clavien-Dindo classification.Recognizing the importance of a multimodal approach for perioperative pain management, we aim to investigate whether a transversus abdominis plane block delivers superior pain control in comparison to perioperative intravenous lidocaine and patient-controlled intravenous analgesia with morphine alone.EudraCT Identifier: 2014-001499-73; 31 July 2014.

Project description:Aim. A double-blind, randomized, placebo-controlled trial was designed to evaluate the efficacy of continuous intraoperative infusion of S(+)-ketamine under intravenous anesthesia with target-controlled infusion of remifentanil and propofol for postoperative pain control. Methods. Forty-eight patients undergoing laparoscopic cholecystectomy were assigned to receive continuous S(+)-ketamine infusion at a rate of 0.3?mg·kg(-1)·h(-1) (n = 24, intervention group) or an equivalent volume of saline at the same rate (n = 24, placebo group). The same target-controlled intravenous anesthesia was induced in both groups. Pain was assessed using a 0 to 10 verbal numeric rating scale during the first 12 postoperative hours. Pain scores and morphine consumption were recorded in the postanesthesia care unit (PACU) and at 4 and 12 hours after surgery. Results. Pain scores were lower in the intervention group at all time points. Morphine consumption did not differ significantly between groups during PACU stay, but it was significantly lower in the intervention group at each time point after PACU discharge (P = 0.0061). At 12 hours after surgery, cumulative morphine consumption was also lower in the intervention group (5.200 ± 2.707) than in the placebo group (7.525 ± 1.872). Conclusions. Continuous S(+)-ketamine infusion during laparoscopic cholecystectomy under target-controlled intravenous anesthesia provided better postoperative pain control than placebo, reducing morphine requirement. Trial Registration. This trial is registered with ClinicalTrials.gov NCT02421913.

Project description:Safe and non-invasive on-demand relief is a crucial and effective treatment for postoperative pain because it considers variable timing and intensity of anesthetics. Ultrasound modulation is a promising technique for this treatment because it allows convenient timed and non-invasive controlled drug release. Here, we created an ultrasound-triggered lidocaine (Lido) release platform using an amino acid hydrogel functioning as three-dimensional (3D) scaffold material (Lido-PPIX@ER hydrogel). It allows control of the timing, intensity and duration of lidocaine (Lido) to relieve postoperative pain. The hydrogel releases Lido due to the elevated reactive oxygen species (ROS) levels generated by PPIX under ultrasound triggering. The Lido-PPIX@ER hydrogel under individualized ultrasound triggering released lidocaine and provided effective analgesia for more than 72 h. The withdrawal threshold was higher than that in the control group at all time points measured. The hydrogel showed repeatable and adjustable ultrasound-triggered nerve blocks in vivo, the duration of which depended on the extent and intensity of insonation. On histopathology, no systemic effect or tissue reaction was observed in the ultrasound-triggered Lido-PPIX@ER hydrogel-treated group. The Lido-PPIX@ER hydrogel with individualized (highly variable) ultrasound triggering is a convenient and effective method that offers timed and spatiotemporally controlled Lido release to manage postoperative pain. This article presents the delivery system for a new effective strategy to reduce pain, remotely control pain, and offer timed and spatiotemporally controlled release of Lido to manage postoperative pain.
