The music video therapy in postoperative analgesia in preschool children after cardiothoracic surgery.

<bold>Objectives: </bold>To observe the effect of music video (MV) therapy on early postoperative pain in preschool children after cardiothoracic surgery.<bold>Methods: </bold>116 preschool children undergoing cardiothoracic surgery were randomly divided into the MV and control groups from June 2019 to March 2020. The related vital signs parameters, the Wong-Baker FACES pain rating scale, the FLACC scale, the number of postoperative PCA press and the cumulants of sufentanil use were recorded and analyzed.<bold>Results: </bold>There were no statistically significant differences in general characteristics and preintervention data between the two groups. However, there were significantly lower in the heart rate, mean arterial pressure, respiratory rate, the number of postoperative PCA press, and the dosage of sufentanil in the MV group than those in the control group after the intervention. The Wong-Baker FACES and FLACC scales in the MV group were significantly lower than those in the control group at the time point of immediately after the first intervention, 1 day, and 2 days after the intervention. The two pain scores showed a downward trend over time, and the corresponding scores in the MV group were better than those in the control group.<bold>Conclusion: </bold>MV therapy can be an effective nonpharmaceutical intervention in the clinical to relieve children's postoperative pain after cardiothoracic surgery.
