Investigation of the Effects of Serratus Posterior Superior Intercostal Plane Block and Serratus Anterior Plane Block on Perioperative Analgesia Management in Patients Scheduled for Mastectomy

Plain-language summary
This study aims to evaluate and compare the analgesic efficacy of two ultrasound-guided regional anesthesia techniques, the serratus anterior plane (SAP) block and the serratus posterior superior intercostal plane (SPSIP) block, in patients undergoing elective mastectomy surgery. Postoperative pain following mastectomy is a common and significant clinical problem that negatively affects patient comfort, delays mobilization, and may prolong hospital stay. Although systemic analgesics are commonly used, they are associated with adverse effects such as sedation, constipation, and potential dependency.
In this randomized clinical study, female patients aged 18-75 years with ASA physical status I-III scheduled for elective mastectomy will be included after obtaining informed consent. Patients will be allocated into two groups to receive either SAP block or SPSIP block under ultrasound guidance prior to surgery. Standardized general anesthesia and perioperative analgesia protocols will be applied to all patients.
The primary objective is to compare postoperative pain scores between the two groups using the Numeric Rating Scale (NRS). Secondary outcomes include time to first analgesic requirement, total analgesic consumption, intraoperative opioid use, and hemodynamic parameters. By comparing these two interfascial plane blocks, this study aims to identify a more effective analgesic technique that improves postoperative pain control, enhances patient comfort, and facilitates early mobilization following mastectomy.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
