A new scientific study conducted in India has proven that listening to instrumental music during surgery can significantly reduce the need for anesthesia in patients. According to The Independent, the study was conducted on 56 patients who underwent gallbladder removal surgery (laparoscopic cholecystectomy) at Lok Nayak Hospital and Maulana Azad Medical College in Delhi.
The main goal of this study, conducted from March 2023 to January 2024, was to reduce the amount of anesthesia and reduce the level of preoperative stress. Although all patients received the same anesthesia kit, only one group listened to music through headphones during the operation. They were accompanied by sedative compositions based on an Indian flute or piano.
The need for anesthesia sharply decreased
According to the results, patients who listened to music needed a significantly smaller amount of the main anesthetic - propofol. They needed an average of 6.7 mg of propofol per kg per hour, and in the control group - 7.86 mg. Experts assessed this as a "visible difference."
At the same time, patients who listened to music did not need fentanyl, a strong painkiller, which is additionally given during surgery when the heart rate or blood pressure rises.
Low stress, quick recovery
The study also found that physiological stress, assessed by the level of cortisol in the blood, is significantly lower. In the control group after surgery, cortisol averaged 536 ml, and in patients who listened to music - 417 ml. This means that the body did not respond to the surgery with strong stress.
Also, in patients who listened to music, the awakening from anesthesia was easy and the recovery process was faster.
Experts evaluate music as an affordable, safe, and clinically applicable supplementary therapy. The study also shows that the use of music in surgical procedures may become popular in the future.
