The Effect of General and Regıonal Anesthesıa on the Neutrophıl / Lymphocyte and Platelet / Lymphocyte Ratıos Durıng Bladder Tumor Surgery; Retrospectıve Study.

BACKGROUND: Among the indicators of SIR are changes in the neutrophil/lymphocyte ratio (NLR) and platelet/lymphocyte ratio (PLR). This study aimed to determine the effect of general and regional anesthesia on SIR during short-term transurethral bladder resection (TUR-B) surgery. METHODS: The 66 included patients were divided into 2 groups: Group 1 (general anesthesia) and Group 2 (regional anesthesia). The lymphocyte, platelet, and neutrophil counts before surgery and 1 h after surgery were obtained from the patients’ records. The indicators of SIR the NLR and PLR were calculated preoperatively and postoperatively. Differences between the groups in the NLR and PLR were investigated. RESULTS: At 1 h postsurgery there weren’t any significant differences in the neutrophil, lymphocyte, platelet counts, or the NLR and PLR in groups, as compared to presurgery; however, the lymphocyte count was higher (but not significantly) in both groups, as compared to presurgery. The neutrophil count and NLR were lower (but not significantly) in Group 1 at postsurgery. CONCLUSIONS: General and regional anesthesia have no effect on postoperative SIR in patients with bladder tumors that may require multiple surgeries and administration of anesthesia; however, we think larger scale prospective studies are needed to more clearly understand neutrophil count and NLR changes in bladder cancer surgery patients administered general anesthesia.
