RESUMEN
BACKGROUND: Burn patients feel a lot of physiological and mental stress during treatment and rehabilitation which often cause anxiety and body image dissatisfaction. This study aimed to compare the effects of the Benson relaxation technique and nature sounds on pain anxiety and body image in burn-injured patients admitted to a burn intensive care unit (BICU). METHODS: This single-blind randomized clinical trial studied 60 burn patients allocated into three groups (Benson relaxation, nature sounds, and control) from September 2021 to February 2022. The patients received the intervention for seven consecutive days in person. Burn Specific Pain Anxiety Scale (BSPAS), was completed on the 1st, 4th, and 7th days. The intervention continued for four weeks measuring body image using the Satisfaction with Appearance Scale (SWAP) at the end of the 1st, 3rd, and 5th weeks. Finally, the data were statistically analyzed using the Shapiro-Wilk test, chi-square test, Fisher's exact test, Bonferroni post hoc test, repeated measures ANOVA, Kruskal Wallis test, and Generalize Estimating Equations (GEE). RESULTS: The mean pain anxiety and dissatisfaction with the appearance were high in the three groups in the pretest. On the 7th day after the intervention, the ANOVA showed that the mean pain anxiety decreased significantly in Benson's relaxation and nature sounds groups in three stages (before intervention (S1), after intervention (S2) and immediately after dressing change (S3) (P < 0.001). Correspondingly, the Kruskal Wallis test revealed that the body image dissatisfaction decreased significantly in the three groups at the end of the 3rd and 5th weeks (P < 0.001). The mean scores of pain anxiety showed that the nature sounds group proved more effective than the Benson relaxation technique. Also, the means scores of body image satisfaction showed that the Benson relaxation technique proved more effective than nature sounds. CONCLUSION: The study findings suggested that the Benson relaxation technique and nature sounds effectively reduces pain, anxiety, and improves body image satisfaction in patients with burn injuries.
