简要总结
Breast cancer is the most common malignancy in women; one of the mainstays of breast cancer treatment is surgery, and modified radical mastectomy is one of the standard treatments. Postoperative pain can seriously reduce the quality of life in patients, and acute pain can even trigger chronic pain syndrome. Thoracic paravertebral, thoracic epidural, intercostal nerve, and interscalene brachial plexus blocks have been used for anesthesia and abrigation during modified radical mastectomy, but their applications are limited due to the complex nature of the procedures and serious complications. In recent years, regional nerve blocks, including intercostal nerve block, erector spinae plane block (ESPB), and paravertebral block, PECS I-II block, serratus anterior plane block (SAPB), and Serratus Posterior Superior Intercostal Plane Block (SPSIPB), have been applied for the treatment of postmastectomy pain in breast cancer patients. SPSIPB has been frequently used for the treatment of acute pain in the postoperative period following surgeries in the thoracic region. SPSIPB is placed on the spine of the scapula in the sagittal plane to identify the second and third ribs under USG guidance. After visualizing the trapezius and serratus posterior superior (SPS) by moving medially to the upper medial border of the scapula, a block is applied to the depths of the SPS from above the 3rd rib. The applied local anesthetic solution spreads under the SPS muscle. Ipsilateral postoperative analgesia is provided with SPSIPB. SPSIPB can be applied on the 3rd rib in one go, or on the 3rd and 4th ribs in two go. Thus, the local anesthetic solution can be distributed more effectively and more effective postoperative analgesia can be provided.

研究组 & 干预措施
Group Single level SPSIPB
The procedure will be performed with the patient in the prone position in the preoperative period. After the scapula is slightly shifted laterally, the US probe is held sagittally at the upper corner of the scapula spine, and the 3rd rib and the serratus posterior superior muscle will be visualized. In plane technique will be used. The block needle will be advanced in the caudo-cranial direction and entered between the serratus posterior superior and the 3rd rib. The block location will be confirmed by injecting 2 ml of saline between the rib and the muscle. After the block location is confirmed, 20 ml of 0.25% bupivacaine will be used.
干预措施: Single level SPSIPB (Procedure)
Group Two-level SPSIPB
The block needle will be advanced in the caudo-cranial direction and inserted between the serratus posterior superior and the 2nd rib. The block location will be confirmed by injecting 2 ml of saline between the rib and the muscle. After the block location is confirmed, 10 ml of 0.25% bupivacaine will be used. Then, the US probe will be held sagittally in the medial part of the scapula spine, and the 4th rib and serratus posterior superior muscle will be visualized. In plane technique will be used. The block needle will be advanced in the caudo-cranial direction and inserted between the serratus posterior superior and the 4th rib. The block location will be confirmed by injecting 2 ml of saline between the rib and the muscle. After the block site is confirmed, 10 ml of 0.25% bupivacaine will be used. A total of 20 ml of 0.25% bupivacaine will be used.
