Brief summary
The main purpose of this study is to compare the effectiveness of two different regional anesthesia techniques for pain management after oncological breast surgeries. The researchers will compare the combined (superficial and deep) serratus anterior plane block with the deep serratus anterior plane block. The study aims to evaluate which method provides better postoperative pain relief, reduces the total consumption of opioid analgesics, and improves patient comfort

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Visual Analog Scale (VAS) Scores for Postoperative Pain | Postoperative 24 hours. | Assessment of postoperative pain using the Visual Analog Scale (VAS) (minimum score: 0, maximum score: 10, where higher scores indicate worse outcome). |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Total Tramadol Consumption | Postoperative 24 hours. | Total amount of tramadol consumed by the patient as rescue analgesia. |
| Need for rescue analgesia | Postoperative 24 hours. | Requirement for additional analgesic medications beyond the standard protocol. |
| Time to first rescue analgesia | Postoperative 24 hours. | Time elapsed from the end of surgery until the first request for rescue analgesia. |
| Postoperative nausea and vomiting (PONV) scores | Postoperative 24 hours. | Assessment of postoperative nausea and vomiting severity. |
| Patient satisfaction | Postoperative 24 hours. | Patient satisfaction level regarding the pain management technique. |
| Block-related complications | Postoperative 24 hours. | Incidence of potential complications related to the block technique (e.g., hematoma, infection, local anesthetic toxicity). |
