Brief Summary

Erector spinae plane block (ESPB) is a novel interfascial block technique first described by Forero in 2016. It has been reported to be effective in various clinical indications. In ESPB, local anesthetic is injected between the deep fascia of the erector spinae muscle and the transverse process of the vertebra, allowing cephalocaudal spread along the erector spinae muscle. The goal of the injection is to provide sensory blockade by affecting the anterior rami of the spinal nerves in the region. ESPB has been used during breast and axillary lymph node surgeries to manage postoperative pain. In addition to tumor cells, immune and inflammatory cells such as neutrophils, platelets, and lymphocytes contribute to the dissemination and invasion of tumor cells into the peripheral circulation. Noninvasive biomarkers such as serum inflammatory markers are increasingly valued for their simplicity and predictive potential. Platelets have been shown to facilitate epithelial-mesenchymal transition of tumor cells; neutrophils support tumor adhesion via growth factors such as VEGF and proteases; lymphocytes play a role in modulating the host immune response to malignancy. The systemic immune-inflammatory index (SII), calculated as (platelet count × neutrophil count) / lymphocyte count, is a relatively new composite marker that reflects immune and inflammatory responses. It has been evaluated as a prognostic biomarker in several cancer-related studies. Postoperative pain and surgical stress activate systemic inflammatory responses. ESPB is performed as part of postoperative analgesia in patients undergoing breast cancer surgery under general anesthesia, based on voluntary participation. The aim of this study is to evaluate the effect of ESPB on postoperative SII levels in comparison to other analgesia modalities.

Outcome Measures

Primary Outcomes (1)

  • Systemic Immune-Inflammation Index (SII)

    Systemic immune-inflammation index (SII) will be calculated using the formula: SII = (Platelet count × Neutrophil count) / Lymphocyte count. This index will be used to evaluate the effect of erector spinae plane block (ESPB) on postoperative systemic inflammation in patients undergoing breast cancer surgery.

    6 hours postoperatively

Secondary Outcomes (1)

  • Postoperative Pain Score

    At 0, 2, 4, and 6 hours postoperatively

Study Arms (2)

Erector spinae plane block

EXPERIMENTAL

Preoperative thoracic level 4 ESP block was applied

Procedure: Erector spinae plane block

Control

NO INTERVENTION

Group with analgesia provided by Contromal (IM) without blockade

Interventions

This study aims to compare the effects of erector spinae plane block (ESPB) and systemic tramadol use as postoperative analgesia methods on the systemic immune-inflammatory index (SII) in patients undergoing breast cancer surgery.
