Randomized controlled trial compares postoperative analgesia using erector spinae plane block or tramadol, revealing different impacts on systemic immune-inflammatory response.
Breast cancer is the most commonly diagnosed malignancy and the leading cause of cancer-specific deaths among women. This study aimed 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. A total of 120 patients were included in the study and divided into 2 groups of 60 each based on the analgesia method: Group E (receiving ESPB) and Group T (receiving tramadol). SII values were measured and analyzed in both preoperative and postoperative periods. In Group T, a significant increase of 1211.78 ± 1345.34 units in postoperative SII measurements compared to the preoperative period was observed (P < .01). In Group E, a significant decrease of 498.36 ± 786.25 units in postoperative SII measurements compared to the preoperative period was noted (P < .01). ESPB was found to provide more effective postoperative analgesia by reducing opioid consumption and demonstrated beneficial effects on inflammatory markers.
