Abstract
BACKGROUND The utility of perioperative intravenous lidocaine in improving postoperative pain control remains unclear. We aimed to compare postoperative pain outcomes in ERP abdominal surgery patients who did vs did not receive intravenous lidocaine. We hypothesized that patients receiving lidocaine would have lower postoperative pain scores and consume fewer opioids. METHODS We performed a retrospective cohort study of patients undergoing elective abdominal surgery at a single institution via an ERP from 2017 to 2018. Patients who received lidocaine in the 6 months prior to a lidocaine shortage were compared to those who did not receive lidocaine for 6 months following the shortage. The primary outcome measures were pain scores as measured on the visual analogue scale and opioid consumption as measured by oral morphine equivalents (OME). RESULTS We identified 1227 consecutive ERP abdominal surgery patients for inclusion (519 patients receiving lidocaine and 708 patients not receiving lidocaine). Demographics between the two cohorts were similar, with the following exceptions: more females, and more patients with a history of psychiatric diagnoses in the group that did not receive lidocaine. Adjusted, mixed linear models for both OME (P = .23) and pain scores (P = .51) found no difference between the lidocaine and no lidocaine groups. DISCUSSION In our study of ERP abdominal surgery patients, perioperative intravenous lidocaine did not offer improvement in postoperative pain scores or OME consumed. We therefore do not recommend the use of intravenous lidocaine as part of an ERP multimodal pain management strategy in abdominal surgery patients.

Abstract
Objective To evaluate whether using a cocktail of intercostal nerve blocks (TINB) during thoracoscopic surgery results in better clinical outcomes than patient-controlled analgesia (PCIA). Methods Patients in two medical groups undergoing video-assisted thoracoscopic surgery (VATS) for pulmonary nodules in West China Hospital of Sichuan University were collected consecutively between March 2022 and December 2022. The groups were divided into two subgroups based on their analgesic program, which were TINB group and PCIA group. The primary outcome was the visual analogue scale (VAS) of the two groups at different stage after surgery and after discharge. Any analgesic related adverse events (ARAEs) were also recorded. Results A total of 230 patients who underwent VATS were enrolled, in which 113 patients (49.1%) received a cocktail TINB after surgery, and 117 patients (50.9%) received a PCIA. After PSM, 62 patients in each group were selected. The difference of resting VAS (RVAS) and active VAS (AVAS) at different stage during hospitalization was only related to the change of period (p < 0.05, p < 0.05), and the two groups showed no significant differences in RVAS or AVAS during hospitalization (p = 0.271, p = 0.915). However, the rates of dizziness (4.84% vs 25.81%, p = 0.002), nausea and vomiting (0 vs 22.58%, p < 0.05), fatigue (14.52% vs 34.87%, p = 0.012), and insomnia (0 vs 58.06%, p < 0.05) in TINB group were lower than that in PCIA group. Besides, AVAS and RVAS at 7, 14, and 30 days after discharge in TINB group were both significantly lower than that in PCIA group (p < 0.05, p < 0.05). Conclusion Cocktail TINB provided better analgesia after discharge and reduced the incidence of ARAEs in patients undergoing VATS.

Abstract
Background Intravenous infusion of lidocaine (IVF-Lido) during the perioperative period is an option to accelerate bowel function recovery after major colorectal surgery. However, previous meta-analyses have shown inconsistent conclusions. Recent randomized controlled trials (RCTs) have been reported after the publication of a previous meta-analysis. Aim We conducted an updated and comprehensive meta-analysis to determine the effects of IVF-Lido on time to first flatus and defecation after major colorectal surgery. Methods We performed a systematic review according to the Preferred Reporting Items for the Systematic Reviews and Meta-Analysis Protocols 2020 guideline. Only RCTs were included. The revised Cochrane risk-of-bias tool was chosen for appraisal. Meta-analysis with meta-regression and trial sequential analysis was carried out. The Doi plot was presented to evaluate publication bias. The Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) methodology was executed to evaluate the certainty of evidence (CoE). Results Thirteen RCTs with 696 participants were enrolled. IVF-Lido significantly decreased the time to first flatus [mean difference (MD) = −6.03 h; 95% confidence interval (CI): (−8.80, −3.26)] and first defecation [MD = −10.49 h; 95% CI: (−15.58, −5.41)]. Trial sequential analysis yielded identical results and ampleness of required information sizes. No obviousness in publication bias was detected, and the CoE in GRADE was low in both outcomes. Meta-regression showed that a significantly shorter time to the first defecation was associated with studies with more improvement in pain control in comparison of two groups and better-improved analgesia in the control group. Conclusions We discretionarily suggest the use of IVF-Lido on postoperative bowel function recovery following major colorectal surgery. Beyond the analgesic effects, IVF-Lido might have additional benefits when postoperative pain relief has already been achieved. Considering the high heterogeneity in this updated meta-analysis, more RCTs are needed. Systematic Review Registration https://inplasy.com/inplasy-2020-7-0023/, INPLASY [202070023].

Abstract
BACKGROUND Previous data show that lidocaine or magnesium has unique characteristics of stress inhibition and antiinflammation. OBJECTIVE We aimed to observe the effects of lidocaine or magnesium on the quality of recovery (QoR) after laparoscopic cholecystectomy. DESIGN Single-centre, prospective, randomised, double-blind study. SETTING The Affiliated Hospital of Xuzhou Medical University from March 2019 to October 2019. PATIENTS One hundred and fourteen patients scheduled for laparoscopic cholecystectomy. INTERVENTION The enrolled patients were randomly divided into three groups. Lidocaine (group L), magnesium sulphate (group M) or 0.9% saline (group C) was administered intravenously 10 min before induction. MAIN OUTCOME MEASURES The quality of recovery 15 (QoR-15) score, the Hospital Anxiety and Depression Scale (HADS), and the Numerical Rating Scale (NRS) score were selected. The usage of propofol and remifentanil, haemodynamic parameters, anaesthesia recovery parameters and adverse events were also evaluated. RESULTS The QoR-15 scores for group L (132.0) and group M (134.0) were 6 and 8 points higher than that of group C (126.0) on POD1 (postoperative day 1) (adjP < 0.05). However, the decrease of QoR-15 in Group L is less than the minimal clinically important difference (8).The NRS scores on POD1 in group C 3, were higher than other two groups (adjP < 0.05). The dosage of remifentanil in group L was lower than other two groups (adjP < 0.05).The physical independence of group L and group M and physical comfort of group M were improved compared with group C. CONCLUSION The results show that magnesium sulphate improved the QoR through improving physical comfort and physical independence in patients after laparoscopic cholecystectomy. However, lidocaine had limited effects on QoR under current conditions. TRIAL REGISTRATION ChiCTR1800019092 (www.chictr.org.cn). CLINICAL TRIAL NUMBER AND REGISTRY URL The study was registered in the Chinese Clinical Trials Register (ChiCTR1800019092) https://www.chictr.org.cn.

Abstract
Abstract
Background
Various multimodal analgesic approaches have been proposed for spine surgery. The authors evaluated the effect of using a combination of four nonopioid analgesics versus placebo on Quality of Recovery, postoperative opioid consumption, and pain scores.
Methods
Adults having multilevel spine surgery who were at high risk for postoperative pain were double-blind randomized to placebos or the combination of single preoperative oral doses of acetaminophen 1,000 mg and gabapentin 600 mg, an infusion of ketamine 5 µg/kg/min throughout surgery, and an infusion of lidocaine 1.5 mg/kg/h intraoperatively and during the initial hour of recovery. Postoperative analgesia included acetaminophen, gabapentin, and opioids. The primary outcome was the Quality of Recovery 15-questionnaire (0 to 150 points, with 15% considered to be a clinically important difference) assessed on the third postoperative day. Secondary outcomes were opioid use in morphine equivalents (with 20% considered to be a clinically important change) and verbal-response pain scores (0 to 10, with a 1-point change considered important) over the initial postoperative 48 h.
Results
The trial was stopped early for futility per a priori guidelines. The average duration ± SD of surgery was 5.4 ± 2.1 h. The mean ± SD Quality of Recovery score was 109 ± 25 in the pathway patients (n = 150) versus 109 ± 23 in the placebo group (n = 149); estimated difference in means was 0 (95% CI, –6 to 6, P = 0.920). Pain management within the initial 48 postoperative hours was not superior in analgesic pathway group: 48-h opioid consumption median (Q1, Q3) was 72 (48, 113) mg in the analgesic pathway group and 75 (50, 152) mg in the placebo group, with the difference in medians being –9 (97.5% CI, –23 to 5, P = 0.175) mg. Mean 48-h pain scores were 4.8 ± 1.8 in the analgesic pathway group versus 5.2 ± 1.9 in the placebo group, with the difference in means being –0.4 (97.5% CI; –0.8, 0.1, P = 0.094).
Conclusions
An analgesic pathway based on preoperative acetaminophen and gabapentin, combined with intraoperative infusions of lidocaine and ketamine, did not improve recovery in patients who had multilevel spine surgery.

Abstract
Multimodal analgesia is defined as the use of more than one pharmacological class of analgesic medication targeting different receptors along the pain pathway with the goal of improving analgesia while reducing individual class-related side effects. Evidence today supports the routine use of multimodal analgesia in the perioperative period to eliminate the over-reliance on opioids for pain control and to reduce opioid-related adverse events. A multimodal analgesic protocol should be surgery-specific, functioning more like a checklist than a recipe, with options to tailor to the individual patient. Elements of this protocol may include opioids, non-opioid systemic analgesics like acetaminophen, non-steroidal anti-inflammatory drugs, gabapentinoids, ketamine, and local anesthetics administered by infiltration, regional block, or the intravenous route. While implementation of multimodal analgesic protocols perioperatively is recommended as an intervention to decrease the prevalence of long-term opioid use following surgery, the concurrent crisis of drug shortages presents an additional challenge. Anesthesiologists and acute pain medicine specialists will need to advocate locally and nationally to ensure a steady supply of analgesic medications and in-class alternatives for their patients’ perioperative pain management.

Abstract
Enhanced recovery after surgery (ERAS) are specially designed multimodal perioperative care pathways which are intended to attain and improve rapid recovery after surgical interventions by supporting preoperative organ function and attenuating the stress response caused by surgical trauma, allowing patients to get back to normal activities as soon as possible. Evidence-based protocols are prepared and published to implement the conception of ERAS. Although they vary amongst health care institutions, the main three elements (preoperative, perioperative, and postoperative components) remain the cornerstones. Postoperative pain influences the quality and length of the postoperative recovery period, and later, the quality of life. Therefore, the optimal postoperative pain management (PPM) applying multimodal analgesia (MA) is one of the most important components of ERAS. The main purpose of this article is to discuss the concept of MA in PPM, particularly reviewing the use of opioid-sparing measures such as paracetamol, nonsteroid anti-inflammatory drugs (NSAIDs), other adjuvants, and regional techniques.

Abstract
BACKGROUND There is limited data on enhanced recovery after surgery (ERAS) protocols after ventral hernia repair (VHR). This study reports the impact of multimodal analgesia on opioid use after open VHR. METHODS Retrospective review of open VHR treated during the initial 6 months after ERAS implementation. Protocol focused on opioid sparing using intraoperative ketamine and/or lidocaine infusion, selective epidural anesthesia, and postoperative ketamine infusion, ketorolac, and acetaminophen. Four groups were analyzed: 1-ERAS protocol with epidural analgesia, 2-historical controls with epidural analgesia prior to ERAS, 3-ERAS protocol without epidural, and 4-historical controls without epidural analgesia, prior to ERAS. Continuous variables were analyzed using ANOVA or Kruskal-Wallis tests, and subgroup analysis using Student's t test or Mann-Whitney U test. Discrete variables were analyzed using Pearson's chi-square test or Fisher's exact test. RESULTS Patients differed in hernia width, but were similar in comorbidity and operative technique. There was no difference in length of stay or readmission. Use of ERAS nearly eliminated patient-controlled analgesia use (group 1, 2.7%; group 2, 68.4%; group 3, 0%; group 4, 65.7%; p < 0.001). ERAS significantly reduced narcotic requirements on postoperative days 0, 1, and 2 (p < 0.001). To account for the bias of selective epidural analgesia, groups 1 and 2 (epidural) and groups 3 and 4 (no epidural) were compared separately. Opioid requirement and PCA use remained significantly lower in patients in the ERAS pathway. CONCLUSION Implementation of multimodal analgesia in the perioperative and postoperative setting significantly reduced opioid use after VHR.
