Music linked to decreased need for sedation

Patients listening to their favorite music required much less sedation during surgery than did patients who listened to white noise or operating room noise, according to a School of Medicine study published in May.

The senior author, Dr. Zeev Kain, professor in the Department of Anesthesiology, says previous studies have shown that music decreases intraoperative sedative requirements in patients undergoing surgical procedures under anesthesia. He wanted to know if the decrease resulted from listening to music or eliminating operating room noise.

The study included 36 patients at Yale-New Haven Hospital and 54 patients at the American University of Beirut Medical Center. The subjects wore headphones and were randomly assigned to hear music they liked or white noise or to wear no headphones and be exposed to operating room noise. Dropping a surgical instrument into a bowl in the operating room can produce noise levels of up to 80 decibels, which is considered very loud to uncomfortably loud.

What the researchers found is that blocking the sounds of the operating room with white noise did not decrease the patients' sedative requirements, while playing music did reduce their need for sedatives during surgery.

"Doctors and patients should both note that music can be used to supplement sedation in the operating room," Kain says.

The lead author was Dr. Chakib Ayoub, with co-authors Dr. Laudi Rizk, Dr. Chadi Yaacoub and Dr. Dorothy Gaal of the University of Beirut Medical Center. The study was supported in part by National Institutes of Health grants.
