Brief Summary

Breast cancer is the most common malignancy in women. Modified radical mastectomy, a surgical procedure in the treatment of breast cancer, is one of the standard treatments. Postoperative pain can seriously reduce the quality of life in patients, and inadequately treated acute pain can trigger chronic pain syndrome. Therefore, thoracic paravertebral block and thoracic epidural block are effective in postoperative analgesia. However, the use of these blocks is limited due to complications. In recent years, less invasive blocks, such as pectoral nerve block (PECS I-II), Serratus anterior plane block (SAPB), Erector spinae plane block (ESPB), and Serratus Posterior Superior intercostal Plane Block (SPSİPB) have been applied. In this study, it was aimed to compare the analgesic effectiveness of ESPB and SPSİPB applications in patients undergoing breast surgery.

Detailed Description

Postoperative pain will be assessed during resting and coughing with a visual analog scale (0-10 cm) and nausea and vomiting with a Postoperative Nausea Vomiting Score at the postoperative 1, 4, 8, 12, and 24 hours. The amount of tramadol consumed in the postoperative period will be recorded. Patient satisfaction will be assessed with the Likert scale at postoperative 24 hours.

Arm && Interventions

Group	Intervention	Description
Erector Spinae Plane Block	Erector Spinae Plane Block	Following the visualization of the anatomical structures, the nerve block needle was advanced via the in-plane technique beneath the erector spinae muscles until the interfascial space was reached. After hydrodissection with 2 ml normal saline, 30 ml of 0.25% bupivacaine was injected into the area.
Serratus Posterior Superior Intercostal Plane Block	Serratus Posterior Superior Intercostal Plane Block	The probe was placed on the spinae scapula in the sagittal plane to identify the second and third ribs. The trapezius, rhomboid, serratus posterior superior muscle were visualized. The needle was inserted just above the third rib deeply into the serratus posterior superior muscle. Two mL isotonic was administrated for the correction. Then, 30 mL of 0.25% bupivacaine was administrated between serratus posterior superior muscle and rib.

Primary Outcome Measures
