The effect of music played to liver transplant donors during surgery on some hemodynamic values and cortisol level

Aim: This study was conducted to determine the effect of music played to liver transplant donors during surgery on some hemodynamic values and cortisol levels. Material and Method: The randomized controlled study was conducted between December 2020 and November 2022 in the operating rooms of İnonu University Liver Transplant Institute. The sample consisted of 90 living liver donors, including 30 music, 30 silence and 30 control groups. Data were collected using the Patient Description, Hemodynamic Parameter Record and Cortisol Level Record Forms. After determining the hemodynamic parameters and cortisol levels of the patients in the music group, 30 minutes of music was applied. Hemodynamic parameters and cortisol levels were determined again immediately after the application (30 minutes). In the analysis of data, two-way analysis of variance tests were used for number, percentile, mean, standard deviation, chi-square, and repeated measurements. Findings: In the comparison between the music, silence and control groups, it was determined that there was no significant difference between the pre-test and post-test pulse rate, systolic blood pressure, diastolic blood pressure, respiratory rate and oxygen saturation mean scores (p>0.05). In intragroup comparisons, the difference between pulse rate, systolic and diastolic blood pressure, oxygen saturation and cortisol level of the music group was found to be significant (p<0.05) When the differences between the pre-test and post-test values of cortisol levels were examined, it was determined that the decrease in the mean score was higher in the music group (p<0.001). Conclusion: It was determined that music played to liver transplant donors during surgery decreased pulse rate, systolic and diastolic blood pressure, increased oxygen saturation, had no effect on respiratory rate, and decreased cortisol levels.
