Impact of Erector Spinae Plane Block on Systemic Immune-inflammation Index

A standardized perioperative care management protocol is applied for all breast-conserving surgery procedures in our department. All patients are informed about ESPB and offered its application preoperatively. Patients who accept the procedure receive ESPB (preoperatively, in the sitting position, at the level of ipsilateral T4 vertebra, USG guided, out-of-plane approach) while those who refuse are subjected to routine intravenous analgesia protocols. All blocks were performed by an anesthesiologist experienced in the application of truncal blocks and 20 cc 0.5% bupivacaine (within the safe dose range for all patients to be used according to their weight) are injected and its spread is visualized under USG.
