Comparison of Serratus Plane Block and Rhomboid Intercostal Plane Block for Postoperative Analgesia in Breast Reduction Surgery
Sponsor: Konul Karaja
Summary
This prospective, randomized clinical study aims to compare the analgesic efficacy of serratus plane block (SPB) and rhomboid intercostal plane block (RIPB) for postoperative analgesia in patients undergoing elective bilateral breast reduction surgery under general anesthesia. All patients will receive standardized general anesthesia. Before induction of anesthesia, while patients are awake, Group SPB will receive an ultrasound-guided serratus anterior plane block and Group RIPB will receive an ultrasound-guided rhomboid intercostal plane block. Postoperative analgesia will be maintained with intravenous patient-controlled analgesia (PCA) with opioids. Primary outcomes include postoperative pain scores and opioid consumption at 1, 6, 12, and 24 hours. Secondary outcomes include time to first analgesic demand, patient satisfaction, and block-related complications.

Serratus Plane Block
"Ultrasound-guided serratus anterior plane block performed preoperatively while patients are awake. A total of 30 mL of local anesthetic solution (5 mL saline, 5 mL of 2% lidocaine, 20 mL of 0.25% bupivacaine) will be used. The total volume will be divided equally between both breasts (15 mL per side), with one injection point on each side at the midaxillary line
Rhomboid Intercostal Plane Block (RIPB)
Ultrasound-guided rhomboid intercostal plane block (RIPB) performed preoperatively while patients are awake, using a total of 30 mL local anesthetic solution (5 mL normal saline, 5 mL of 2% lidocaine, and 20 mL of 0.25% bupivacaine). The total volume will be divided equally between both breasts (15 mL per side), with one injection point on each side between the rhomboid major muscle and the intercostal muscles at the medial border of the scapula around the 5th intercostal level.
No Regional Block (Control)
Participants in this group will not receive any regional block. Standard general anesthesia and multimodal postoperative analgesia will be provided according to institutional protocol.
