Summary

This randomized controlled trial evaluates whether perioperative intravenous lidocaine infusion, combined with port-site ropivacaine infiltration, improves postoperative recovery after laparoscopic abdominal surgery. Participants will be assigned 1:1 to receive either intravenous lidocaine during surgery plus ropivacaine infiltration at surgical closure, or ropivacaine infiltration alone. The primary endpoint is postoperative quality of recovery measured by the QoR-15 questionnaire. Secondary endpoints include postoperative pain and opioid consumption, as well as plasma lidocaine and ropivacaine concentrations to assess systemic exposure and safety.

Detailed description

Participants will be randomly assigned in a 1:1 ratio to one of two perioperative analgesic strategies: * Experimental group: intravenous lidocaine infusion during surgery combined with port-site ropivacaine infiltration at surgical closure * Control group: port-site ropivacaine infiltration alone at surgical closure (standard care) In the experimental arm, lidocaine will be administered at induction of general anesthesia with an intravenous bolus dose of 1.5 mg/kg followed by a continuous infusion of 2 mg/kg/hour. Dosing will be based on actual body weight, with adjustment for patients with obesity (BMI ≥ 30 kg/m²) using adjusted body weight. The infusion will be discontinued at the time of surgical closure, immediately prior to trocar-site infiltration with ropivacaine. In both groups, trocar/port-site infiltration will be performed by the surgeon at the end of the procedure using ropivacaine 2 mg/mL, with a maximum total volume of 20 mL, injected into the deep musculo-aponeurotic layers of trocar incisions. All participants will receive standardized general anesthesia and a multimodal postoperative analgesia regimen according to institutional protocols, including scheduled non-opioid analgesics and rescue opioids as needed based on pain intensity. To assess systemic exposure and safety, plasma concentrations of lidocaine will be measured at predefined time points: 30 minutes after initiation of infusion, at surgical closure, and at 30 minutes, 2 hours, and 6 hours postoperatively. Plasma ropivacaine concentrations will also be measured after infiltration (30 minutes, 2 hours, and 6 hours). These measurements will allow evaluation of peak concentrations, variability, and potential accumulation. The primary objective of the study is to determine whether the addition of perioperative intravenous lidocaine improves postoperative quality of recovery, assessed using the QoR-15 questionnaire at the predefined postoperative time point(s) specified in the protocol. Secondary objectives include evaluation of postoperative pain intensity, opioid consumption, and other recovery-related outcomes. In addition, to characterize systemic exposure and support safety assessment of the combined local anesthetic strategy, plasma concentrations of lidocaine will be measured at predefined time points (30 minutes after initiation of infusion, at surgical closure, and at 30 minutes, 2 hours, and 6 hours postoperatively). Plasma ropivacaine concentrations will be measured after infiltration (30 minutes, 2 hours, and 6 hours). These measurements will allow evaluation of peak concentrations, variability, and potential accumulation relative to predefined safety thresholds. This trial will provide clinically relevant evidence regarding the impact of perioperative intravenous lidocaine on patient-centered recovery after laparoscopic surgery, while also documenting pharmacokinetic exposure and safety when combined with port-site ropivacaine infiltration.
