Acute pain after breast surgery can significantly reduce the quality of life for patients. If acute pain is not adequately treated, it can develop into chronic pain. Thoracic epidural analgesia, thoracic paravertebral block, erector spinae plane block, and serratus anterior plane block are frequently applied blocks. However, ESPB, being a fascial plane block, can yield inconsistent results regarding distribution and dermatomal area. In recent years, there has been an increase in publications applying ESPB from two levels to achieve wider distribution. As a result, this study aims to compare the analgesic efficacy of single-level (Thoracic 3) and two-level (Thoracic 2, Thoracic 4) ESPB applications.

One-level Erector Spinae Plane Block will be performed unilaterally, under US guidance, before the surgical operation, and when the patient is placed in the lateral decubitus position. In applications, 30 ml of 0.25% bupivacaine will be injected at the T3 level.
Bi-level Erector Spinae Plane Block will be performed unilaterally, under US guidance, before the surgical operation, and when the patient is placed in the lateral decubitus position. In applications, 15 ml of 0.25% bupivacaine at T2 level and 15 ml of 0.25% bupivacaine at T4 level will be injected.

RECRUITINGPain scores
Pain will be assessed at the 4th-hour rest using the visual analog scale on a scale from 0 mm (no pain) to 100 mm (worst pain).
Time frame: 4th-hour after surgery
Pain scores
Pain will be assessed at rest using the visual analog scale on a scale from 0 mm (no pain) to 100 mm (worst pain). Pain assessment will be done at the 1st, 2nd, 12th, and 24th hours after surgery.
Time frame: Up to 24 hours after surgery
Pain scores
Pain will be assessed while coughing using the visual analog scale on a scale from 0 mm (no pain) to 100 mm (worst pain). Pain assessment will be done at the 1st, 2nd, 6th, 12th, and 24th hours after surgery.
Time frame: Up to 24 hours after surgery
Tramadol Consumption
Postoperative intravenous tramadol infusion therapy will be administered with the patient-controlled analgesia (PCA) method. Thanks to PCA, how much morphine the patient needs will be followed in mg.
Time frame: Up to 24 hours after surgery
Side effects
Side effects, such as allergy to local anesthetics, hypotension, nausea/vomiting, and itching, will be recorded.
Time frame: Up to 24 hours after surgery
