This prospective observational study aims to evaluate the effects of intradermal methylene blue injection on intraoperative hemodynamic stability in patients undergoing breast surgery under general anesthesia. While methylene blue is commonly used for sentinel lymph node mapping, its potential systemic vasopressor effects remain unclear. To provide a comprehensive analysis, the study will compare patients receiving methylene blue with a control group of patients undergoing similar breast procedures without the use of any dye. Hemodynamic parameters such as blood pressure, heart rate, and oxygen saturation will be recorded and compared between the two groups to determine the specific impact of methylene blue on the incidence of intraoperative hypotension and the need for vasopressor support.

Comparison of Intraoperative Hemodynamic Stability Between Methylene Blue and Control Groups
Timeframe: From the induction of anesthesia until the end of the surgical procedure (approximately 1 to 3 hours per patient).
