Objective:

Acute pain is one of the main symptoms reported by patients during the postoperative period of cardiac surgery, where the use of music has reported positive effects. Therefore, this study sought to determine the effectiveness of a nursing intervention based on music as a non-pharmacological treatment of pain in the postoperative period of cardiac surgery.

Methods:

Mixed study, with a quantitative phase of the Randomized Clinical Trial type with a 3-level unifactorial statistical design, and an additional qualitative phase that examines participants' experience after the Nursing intervention. With a total of 45 participants assigned to the control and experimental groups (with 2 levels of intervention), the level of perceived pain was measured to subsequently address patients' perception after intervention through a semi-structured interview.

Results:

The quantitative phase showed a statistically significant change in the perception of pain after intervention in the experimental groups (p = 0.016). In the qualitative phase, 3 categories were determined: Participants' experience with the use of recorded music; aspects of the execution of session of music use, and patient recommendations to enrich the intervention. Likewise, it was determined that the time selected for the intervention turns out to be sufficient from the perspective of participants.

Conclusion:

The proposed intervention was effective in reducing postoperative pain in the two intervention groups. Besides, it was observed that this intervention produced additional positive effects in the participants, such as relaxation, distraction, and tranquility.
