The Effects of music therapy on Pain Threshold, Anxiety, distress response and Hemodynamic Parameters during dressing changes in burn patients

Music is one of the non-pharmacotherapeutic approaches of pain relief. This study was done to investigate the effect of music (selective and nonselective) in reducing pain، anxiety and behavioral reactions and changes of hemodynamic parameters in the burned patients during the daily dressing changing. This clinical trial was done on 90 burned patients of Shahid Rajaei Hospital of Qazvin، Iran، in 2012 that were selected via purposeful sampling method and randomly divided into three control، selected music and nonselective music groups. Data were collected by interview، self-reporting and document observing with the demographic، the Spielberger and pain behavioral questionnaires and pain intensity recording sheet. The hemodynamic status (heart rate، blood pressure and respiratory rate) of the patient was measured during dressing changing. Data were analyzed using one-way ANOVA and Tukey’s post hoc tests. Music caused a significant reduction of pain and also anxiety in the burned patients (p<0. 05). The selective music caused a significant reduction of behavioral reactions to pain (p=0. 02). Selective and nonselective music caused significant modification of heart rate of the patients (p<0. 05). Music، especially the familiar type can have positive effects in reducing anxiety، pain and controlling some vital sings of burned patients.
