Background: The neutrophil-to-lymphocyte ratio (NLR) and lymphocyte-to-monocyte ratio (LMR) are inflammatory biomarkers. Until now, it is unknown the impact of opioid dosage on perioperative immunity in glioma patients. The aim of this study was to explore the effect of intraoperative opioid dosage on perioperative immune perturbations using NLR and LMR as inflammatory biomarkers and evaluate the correlation between inflammatory biomarkers and pathological grade of glioma.

Methods: The study included 208 patients with primary glioma who underwent glioma resection from February 2012 to November 2019 at Harbin Medical University Cancer Hospital. Complete blood count (CBC) was collected at 3 time points: one week before surgery, and 24 hours and one week after surgery. Patients were divided into high-dose and low-dose groups, based on the median value of intraoperative opioid dose. The relationships between perioperative NLR, LMR and intraoperative opioid dosage were analyzed using repeated measurement analysis of variance (ANOVA). Correlations between preoperative various factors and pathological grade were analyzed by Spearman analysis. Receiver operating characteristic (ROC) curves were performed to assess the predictive performance of the NLR and LMR for pathological grade.

Results: The NLR (=0.020) and lower LMR (=0.037) were statistically significant different between high-dose and low-dose groups one week after surgery. The area under the curve (AUC) of the NLR to identify poor diagnosis was 0.685, which was superior to the LMR (AUC: 0.607) and indicated a correlation between the NLR with pathological grade. The preoperative NLR (=0.000), LMR (=0.009), age (=0.000) and tumor size (=0.001) exhibited a significant correlation with the pathological grade of glioma.

Conclusion: Intraoperative opioids in the high-dose group were associated with higher NLR and lower LMR in postoperative glioma patients. The preoperative NLR and LMR demonstrated predictive value for distinguishing between high-grade and low-grade gliomas.

Thoracic outlet syndrome (TOS) is an uncommon condition defined by the compression of neurovascular structures within the thoracic outlet. When conservative management strategies fail to alleviate symptoms, surgical decompression becomes necessary. The purpose of this study is to evaluate and compare the efficacy and safety of regional anesthesia (RA) using spontaneous breathing in contrast to general anesthesia (GA) for patients undergoing surgical intervention for TOS.

The Rise of Fentanyl: Molecular Aspects and Forensic Investigations.

Int J Mol Sci

January 2025

Legal Medicine, Department of Medical, Surgical and Advanced Technologies "G.F. Ingrassia", University of Catania, 95123 Catania, Italy.

Fentanyl is a synthetic opioid widely used for its potent analgesic effects in chronic pain management and intraoperative anesthesia. However, its high potency, low cost, and accessibility have also made it a significant drug of abuse, contributing to the global opioid epidemic. This review aims to provide an in-depth analysis of fentanyl's medical applications, pharmacokinetics, metabolism, and pharmacogenetics while examining its adverse effects and forensic implications.

Anesthesia depth monitoring during opioid free anesthesia - a prospective observational study.

BMC Anesthesiol

Department of Anesthesiology and Intensive Care Medicine, Halland Hospital Halmstad, Lasarettsvägen, Halmstad, SE-30581, Sweden.

Background: Patients undergoing general anesthesia are more frequently monitored for depth of anesthesia using processed electroencephalography. Opioid-free anesthesia is nowadays an accepted modality for general anesthesia, however it is unclear how to interpret data from processed electroencephalography when using a mixture of non-opioid anesthetic drugs. Our objective was to describe density spectral array patterns and compare processed encephalographic data indices between opioid-free and routine opioid based anesthesia.

Background: Lichtenstein hernia repair is a common surgical procedure. Previously, combined rectus sheath (RS) and transversus abdominis plane (TAP) blocks have been shown to be beneficial in laparoscopic inguinal hernia surgery. Our hypothesis is that combining the two blocks will also be beneficial in open Lichtenstein hernioplasty day-case procedures.
