Introduction: The management of postoperative pain following lumbar disc herniation (LDH) surgery is crucial for the quality of recovery. The effectiveness of multimodal analgesia plans increases when interfascial plane blocks are included. This study sought to compare the analgesic efficacy of preoperative ultrasound-guided TLIP (thoracolumbar interfascial plane) blocks and posterior QLBs (quadratus lumborum blocks) in patients undergoing LDH surgery. Methods: Patients undergoing elective LDH surgery under general anesthesia were randomized into two groups: thoracolumbar interfascial plane block (Group T) and posterior quadratus lumborum block (Group Q). Block applications were performed 30 min before anesthesia induction. In the postoperative period, analgesia control was provided with a patient-controlled analgesia device. The patients’ 24 h cumulative opioid consumption was examined. Pain scores were evaluated in the 0th, 3rd, 6th, 9th, 12th, and 24th hours. Results: The mean 24 h cumulative morphine consumption for patients was statistically insignificant when Groups T and Q were compared (9.14 ± 7.03 mg vs. 8.66 ± 6.58 mg, p = 0.788). Pain scores at rest and during movement as well as morphine consumption were similar between groups in the 0th, 3rd, 6th, 9th, 12th, and 24th hours (p > 0.05). Conclusions: The study determined that the utilization of TLIP blocks and posterior QLBs prior to anesthesia induction yielded comparable outcomes in terms of reducing postoperative analgesic consumption and enhancing the efficacy of multimodal analgesia in individuals undergoing single-distance lumbosacral spine surgery under general anesthesia.

Background and Objectives: Total knee arthroplasty (TKA) is a commonly performed orthopedic procedure, and is often accompanied by significant postoperative pain. The supra-inguinal fascia iliaca block (SIFIB), similar to an anterior lumbar plexus block, is frequently used in hip surgeries. The interspace between the popliteal artery and capsule of the posterior knee (IPACK) block is a regional anesthesia technique that targets the posterior innervation of the knee capsule. This retrospective study aimed to compare the analgesic effects of SIFIB and SIFIB + IPACK on patients undergoing TKA under spinal anesthesia. Materials and Methods: This retrospective study revealed the data collected from a tertiary hospital. Patient data were gathered for individuals who underwent unilateral TKA under spinal anesthesia during the period between 1 January 2023 and 1 September 2023. Inclusion criteria comprised patients falling within ASA class I–III, those following a standardized perioperative analgesia regimen, and individuals receiving opioids via a patient-controlled analgesia device (PCA) as part of their postoperative pain management strategy. Patients were grouped as SIFIB and SIFIB + IPACK according to the performed regional anesthesia technique. Results: In the study, the data of 88 patients in total, 61 in the SIFIB group and 27 in the IPACK group, were analyzed. The 24 h cumulative morphine consumption was similar in the SIFIB and SIFIB + IPACK groups (10.62 ± 6.58 mg vs. 12.55 ± 8.84 mg, respectively; p: 0.258). The NRS scores of the groups were similar in all time frames. Conclusions: Our study reveals that combining IPACK with SIFIB in the multimodal analgesia plan does not provide additional benefits in terms of postoperative opioid consumption and pain scores in patients undergoing unilateral THA under spinal anesthesia.

Aim: Through this study, we aim to investigate whether biomarkers like the neutrophil-lymphocyte ratio (NLR), platelet lymphocyte ratio (PLR), and systemic immune-inflammatory index (SII) might predict the postoperative first 24 hours analgesic requirement and pain scores of patients undergoing laparoscopic cholecystectomy. Material & Method: After receiving the local ethical board approval, records of 67 patients, aged between 18 and 75 years, with ASA classifications I-III who underwent elective laparoscopic cholecystectomy were retrospectively evaluated to record postoperative analgesic requirements and numerical pain scale (NRS) scores. NLR, PLR, and SII scores were calculated from preoperative hemograms and compared with analgesic requirements and NRS scores. Results: The data of 67 patients were evaluated. There was no correlation between postoperative tramadol use and NRS scores, PLR, or SII values (p>0.05). NRS scores and the cumulative 24-hour postoperative tramadol use were correlated (p=0.0001), as it was observed that patients with high NRS scores used higher amounts of tramadol. Additionally, a poor statistically significant correlation was found between PDW (Platelet distribution width) value and tramadol dose (AUC = 0.611). Conclusion: No significant association between NLR, PLR, SII, pain scores, and tramadol use was detected.

Aim Our aim in this study was to investigate the effect of inhaled and intravenous (iv) magnesium (Mg) use on Integrated Pulmonary Index (IPI) score and propofol consumption in patients undergoing endobronchial ultrasonography (EBUS) procedure under sedoanalgesia. Materials and methods After obtaining the approval of the local ethics committee, the files of 96 patients aged 18-75 who underwent EBUS were reviewed retrospectively. Patients using Mg were classified as the M group, and patients not using Mg were classified as the control (C) group. IPI values, amount of propofol consumed, and intubation scores of group M and group C were evaluated. Results When the intubation score values ​​at the time of the bronchoscope passing through the vocal cords (assessment of vocal cord movement, cough reflex, and leg movement) during the EBUS procedure were compared, the intubation conditions were found to be significantly better in the M group than in the C group (p<0.05). Group M had less cough reflex than group C (p<0.05). IPI scores were significantly higher in the M group than in the C group at the 10th and 15th minutes (p<0.05). Total propofol consumption was found to be significantly lower in the M group (254.61±82.80 mg) than in the C group (321.25±90.04 mg) (p<0.05). Conclusion According to our results, the use of intravenous and inhaler Mg in addition to propofol sedation during the EBUS procedure may improve the respiratory parameters and can also significantly reduce the propofol dose.

Sedation is often required during flexible fiberoptic bronchoscopy (FFB) to ensure patient comfort and the success of the procedure. The choice of sedative agents may differ between anesthesiologists and pulmonologists. This pilot study aimed to investigate the current pre-procedure preparation, monitoring, premedication and sedation practices for FFB in Türkiye, focusing on the preferences and practices of pulmonologists. A structured survey consisting of 30 questions was distributed to pulmonologists at various hospitals in Türkiye via Google Forms. A total of 97 responses were received, of which 80 were analyzed. Participants were divided into two groups based on their FFB experience: Group 1 with ≥10 years of experience and Group 2 with <10 years of experience. The majority of pulmonologists ordered complete blood count, biochemistry, and coagulation tests before the procedure. The most preferred oral ingestion duration was 6-8 hours. Additionally, 98% of the physicians reported using at least one agent for premedication purposes. Routine topical local anesthetic use was high in both groups (88.3% and 85%, respectively). In addition, 40% of the physicians stated that they always applied sedation during FOB, and 48% stated that they applied sedation in certain situations, and that patient request was the most effective factor. Without the assistance of an anesthesiologist, pulmonologists preferred mono midazolam or a combination of midazolam and fentanyl for sedation. In Group I, two physicians reported using dexmedetomidine for combination sedation. It was also determined that propofol was not used in cases where an anesthesiologist was not available. Additionally, 47% of the physicians reported that they found current sedation practices completely adequate. Findings highlight the variability in sedation practices for FFB in Türkiye and underscore the need for standardized guidelines to optimize patient care and procedural outcomes. This study can be considered as a fundamental step towards more comprehensive studies by pulmonologists.
