The effects of musical stimulation on the level of consciousness among patients with head trauma hospitalized in intensive care units: A randomized control trial. (February 2021) - Yekefallah, Leili
Abstract: Background: Improvement in the level of consciousness (LOC) is considered as an indicator of recovery among patients with head trauma (HT). musical stimulation is a simple noninvasive intervention with potential positive effects on LOC. This study evaluated the effects of musical stimulation on LOC among patients with HT hospitalized in intensive care unit. Methods: This clinical trial was conducted in 2018–2019. Fifty-four patients with HT were purposively and consecutively recruited from two trauma intensive care units in Qazvin, Iran, and randomly allocated to a control (n = 27) and an intervention (n = 27) group. Participants in the intervention group received fifteen-minute musical stimulation once daily for seven consecutive days using an MP3 player and a headphone for their counterparts, the headphones were silent for 15 min without receiving any musical stimulation once daily for seven consecutive days. A demographic questionnaire, the Glasgow Coma Scale, and the Richmond Agitation-Sedation Scale were used for data collection. LOC was daily assessed before and after each musical stimulation session. The SPSS program (v. 23.0) was used for data analysis at a significance level of less than 0.05. Findings: There were significant between-group differences respecting the posttest mean score of LOC in the third, fourth, fifth, sixth, and seventh days of the study intervention (P < 0.05)., the posttest mean score of LOC in the intervention group significantly increased in the intervention group (P < 0.0001), while it did not significantly change in the control group (P > 0.05). Conclusion: musical stimulation is effective in significantly improving LOC among hospitalized patients with HT. Therefore, it can be used as a non-expensive noninvasive intervention to improve treatment outcomes among these patients. Highlights: Music therapy is effective in significantly improving LOC among hospitalized patients with HT. Music therapy can be used as a non-expensive noninvasive intervention to improve treatment outcomes among these patients. Music therapy facilitated recovery of patients with HT and imposes on costs on healthcare systems. Auditory stimulation is more widely used for providing sensory stimulation to patients with altered LOC because the auditory sense is the last sense which is lost during coma and is easier to use by critical care nurses in ICU.
