The Effect of Music Played to Liver Transplant Donors During Surgery on Hemodynamic Parameters and Cortisol Levels: A Randomized Controlled Trial
The Effect of Music Played to Liver Transplant Donors During Surgery on Hemodynamic Parameters and Cortisol Levels: A Randomized Controlled Trial
This randomized controlled trial investigates the effects of music played during liver donor surgery on hemodynamic parameters and cortisol levels. Ninety participants were divided into three groups: music, silence (with headphones but no sound), and a control group with no intervention. The study aimed to evaluate whether music can reduce stress-related physiological responses during surgery.
This study was designed to evaluate the effects of music played during surgery on liver transplant donors. The research included 90 adult participants who underwent live liver donation surgeries. Participants were randomly assigned to one of three groups: music group (headphones with music), silence group (headphones without sound), and a control group (no headphones). Music intervention lasted for 30 minutes during the operation.
The primary objective was to examine whether intraoperative music exposure could reduce physiological stress, measured via cortisol levels. Secondary outcomes included changes in hemodynamic parameters such as systolic and diastolic blood pressure, pulse rate, oxygen saturation, and respiratory rate. Measurements were taken before and after the surgery.
The study was conducted at İnönü University Liver Transplant Institute, with ethical approval granted by the Malatya Clinical Research Ethics Committee (Approval No: 2021/52). The findings suggest that music may be an effective supportive intervention for reducing surgical stress.
