Summary
Brief summary (as posted)
This prospective observational study aims to evaluate the effect of anesthesiologist gender and patient-anesthesiologist gender concordance, as well as the analgesia method, on postoperative pain levels and analgesic requirements in patients undergoing elective mastectomy for breast cancer. The study will also investigate the impact of these factors on intraoperative and postoperative anesthesia-related complications. Findings are expected to contribute to the understanding of gender-based differences in patient outcomes and guide improvements in perioperative care.

- label
- Male Anesthesiologist Group
- description
- Patients undergoing elective mastectomy for breast cancer who receive anesthesia care from a male anesthesiologist. All anesthesia and analgesia procedures will be performed according to the hospital's standard protocols. The type of analgesia (nerve block, patient-controlled analgesia \[PCA\], or intravenous analgesics) will be recorded, but not influenced by the research team. Postoperative pain scores, analgesic requirements, and anesthesia-related complications will be prospectively monitored and documented.
- label
- Female Anesthesiologist Group
- description
- Patients undergoing elective mastectomy for breast cancer who receive anesthesia care from a female anesthesiologist. All anesthesia and analgesia procedures will be performed according to the hospital's standard protocols. The type of analgesia (nerve block, patient-controlled analgesia \[PCA\], or intravenous analgesics) will be recorded, but not influenced by the research team. Postoperative pain scores, analgesic requirements, and anesthesia-related complications will be prospectively monitored and documented.
