Intraoperative Music and Propofol Consumption in Breast Surgery
The Effect of Intraoperative Music on Propofol Consumption and BIS Values in Patients Undergoing Elective Breast Surgery: A Randomized Controlled Trial
The goal of this study is to find out whether listening to music during surgery can reduce the amount of propofol, an anesthesia medicine, needed in patients having elective breast surgery.
Patients who agree to take part will be randomly assigned to one of two groups. One group will listen to music of their choice through headphones during anesthesia and recovery. The other group will receive standard anesthesia care without music. All patients will receive routine anesthesia monitoring, including a monitor that helps assess the depth of anesthesia.
The main outcome of the study is the total amount of propofol used during surgery. The study will also look at anesthesia depth values, use of other anesthesia medicine, blood pressure and heart rate, time spent in the recovery unit, nausea and vomiting after surgery, and patient satisfaction.

Descrição detalhada
This is a single-center, prospective, randomized, controlled, two-arm study conducted at Bursa Uludag University Faculty of Medicine, Department of Anesthesiology and Reanimation. The study population will include adult patients scheduled for elective breast surgery under total intravenous anesthesia.
After providing written informed consent, eligible participants will be randomized into two groups. The control group will receive routine anesthesia care in a standard operating room environment. The music group will receive the same anesthesia protocol and will listen to self-selected music using noise-cancelling Bluetooth headphones from immediately before anesthesia induction until discharge from the post-anesthesia care unit.
All patients will undergo standard intraoperative monitoring, including electrocardiography, noninvasive blood pressure, pulse oximetry, capnography, and bispectral index monitoring. Anesthesia will be induced and maintained according to a standardized total intravenous anesthesia protocol using propofol and remifentanil. Propofol administration will be titrated to maintain the BIS value within the target range of 40-60.
The primary outcome is total propofol consumption expressed as mg/kg. Secondary outcomes include intraoperative BIS values recorded at regular intervals, remifentanil consumption, heart rate and blood pressure measurements, post-anesthesia care unit length of stay, postoperative nausea and vomiting, and patient satisfaction before discharge from the post-anesthesia care unit.
