Ear buds were taped to the participants' ears before each procedure and the volume was adjusted so the music was only audible to the patient. Then, after the initial dose of a sedative commonly used during a colonoscopy, it was randomly determined if the music would be played during the procedure itself. Further doses of the sedative were given if necessary.
After the procedure, each patient was asked about their discomfort and pain levels during the procedure and if they had any anxiety.
From their data, the researchers determined that those who listened to music during the colonoscopy needed approximately one less dose of the sedative mediation, while still reporting about the same levels of comfort as those who did not listen to music.
If music does indeed reduce the amount of sedation a patient needs for a colonoscopy, it could lead to reduced healthcare costs and greater satisfaction with the overall procedure.
"Over all, colonoscopies are very, very safe." Krevsky said. "And while the risks of sedatives are relatively small, in general, less medication is better."
The type of music the patients selected didn't seem to matter. Krevsky even suggests toting along your mp3 player to your next colonoscopy. Your favorite tunes may make the procedure a little easier to bear.
