Abstract
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. 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 significantcorrelation was found between PDW (Platelet distribution width) value and tramadol dose (AUC = 0.611). No significant association between NLR, PLR, SII, pain scores, and tramadol use wasdetected.
