Effect of Musical Hearing On Anxiety, Pain, and Cardiorespiratory Parameters in Cardiac Surgery: Study Protocol of a Randomized Clinical Trial

Abstract Background Preoperative anxiety and postoperative pain are frequent in cardiac surgeries and constitute important stressors for the patient, which can cause several complications. Among the various strategies that aim to alleviate these phenomena is musical hearing as a non-pharmacological intervention. The aim of this study is to evaluate the effect of musical hearing on preoperative state-anxiety, postoperative pain, at rest and cough stimulus, and cardiorespiratory parameters in patients undergoing cardiac surgery. Methods A randomized, parallel, simple masking clinical trial will be conducted with patients 18 years of age or older who have undergone elective cardiac surgery by sternotomy, who accept to participate in the research and sign the consent. Study participants will be randomly divided, in a 1:1 ratio, to one of the two groups, experimental (subjected to music listening for 20 minutes in the pre and postoperative period) or control (standard care in the pre and post -operative), using a randomization scheme generated by the website. The sample size calculation was obtained after conducting a pilot study. Discussion The results of the study may contribute to the implementation of non-pharmacological interventions in health services, highlighting the protocols of musical hearing, to minimize anxiety and pain in cardiac surgery.
