RESUMEN
PURPOSE: We designed this study to evaluate the impact of intraoperative intravenous lidocaine infusion on postoperative opioid consumption after laparoscopic cholecystectomy. METHODS: In 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. RESULTS: Our 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. CONCLUSION: Overall, lidocaine did not have any effect on postoperative analgesia after laparoscopic cholecystectomy.

INTRODUCTION: Soluble urokinase plasminogen activator receptor (suPAR) is an emerging biomarker of the level of chronic systemic inflammation and the general condition of the patient. We aimed to investigate the impact of general anesthesia and major surgery on perioperative suPAR and C-reactive protein (CRP) levels. METHODS: This study included patients undergoing elective major noncardiac surgery with an expected duration of ≥2 h under general anesthesia. Inclusion criteria were age ≥18 years and American Society of Anesthesiologists' physical status I-IV. Blood was drawn 30 min prior to induction of anesthesia (preoperatively), as well as 30 min after emergence from anesthesia (postoperatively). Plasma suPAR levels were determined using the suPARnostic® Quick Triage lateral flow assay. CRP measurements were performed by particle-enhanced immunoturbidimetric assay. RESULTS: The difference in preoperative and postoperative suPAR levels was not statistically significant (7.7 [5.28-10.4] ng/mL vs. 7.15 [5.68-9.8] ng/mL, p = 0.462). CRP levels increased significantly during surgery (0.81 [0.24-2.1] mg/dL vs. 5.76 [2.2-8.75] mg/dL, p < 0.001). No correlation was observed between CRP and suPAR levels, both preoperatively (rho = 0.127; p = 0.208) and postoperatively (rho = 0.017; p = 0.87). A statistically significant increase was also observed in postoperative white blood cell count (7.576 vs. 10.711, p < 0.001). CONCLUSION: General anesthesia and operative trauma did not affect perioperative suPAR levels despite the activation of systemic inflammatory response.

Arthroscopic anterior cruciate ligament (ACL) reconstruction with hamstring grafting is a common orthopedic procedure that is associated with moderate-to-severe pain. Peripheral nerve blockade as an anesthetic technique is an appealing option in the era of modern anesthesia. The aim of this narrative review is to document the efficacy and safety of the combination of femoral, obturator, and sciatic (FOS) nerve blocks as an exclusive method for anesthesia in patients undergoing ACL reconstruction. An electronic search of the literature published up to October 2023 was conducted in the Medline, Embase, Cochrane, Web of Science, and Google Scholar databases to find studies on ACL reconstruction and peripheral obturator nerve block. Overall, 8 prospective studies-with a total of 315 patients-published between 2007 and 2022 were included in this review. Ultrasound-guided peripheral FOS nerve blockade is an effective anesthetic technique for ACL reconstruction, offering good perioperative pain management, minimal opioid consumption, and an excellent safety profile. Further well-designed prospective studies are needed to determine the best approach for obturator nerve blockade and the appropriate type and dosage of local anesthetic.
