Brief Summary: This study aims to compare the effects of spinal versus general anesthesia on the inflammatory response measured by Delta Neutrophil Index (DNI) in patients undergoing total knee arthroplasty. The study is prospective and observational. A total of at least 84 patients will be included, with anesthesia type determined according to routine clinical practice. Preoperative and postoperative blood tests will be analyzed, and no additional blood samples will be required.
Detailed Description: This prospective observational study will be conducted at Elazig Fethi Sekin City Hospital, Department of Anesthesiology and Reanimation. Patients undergoing total knee arthroplasty will be assigned to two groups based on the anesthesia method used in routine practice: spinal anesthesia or general anesthesia. The primary outcome measure is the Delta Neutrophil Index (DNI), an inflammation marker automatically calculated by hematology analyzers using complete blood count parameters. DNI values will be compared preoperatively and postoperatively between groups. Additional data including age, sex, ASA classification, duration of surgery, hemogram parameters, and perioperative complications will be collected. The sample size calculation indicated that a minimum of 42 patients per group (total 84) are required to detect significant differences in DNI levels with 80% power at a 5% significance level. Statistical analyses will include Kolmogorov-Smirnov test for normality, independent t test or Mann-Whitney U test for between-group comparisons, and paired t test or Wilcoxon test for within-group comparisons. A p-value \<0.05 will be considered statistically significant.
