A systematic review of the comparative effects of sound and music interventions for intensive care unit patients' outcomes.

Background: Despite syntheses of evidence showing efficacy of music intervention for improving psychological and physiological outcomes in critically ill patients, interventions that include nonmusic sounds have not been addressed in reviews of evidence. It is unclear if nonmusic sounds in the intensive care unit (ICU) can confer benefits similar to those of music.

Objective: The aim of this study was to summarise and contrast available evidence on the effect of music and nonmusic sound interventions for the physiological and psychological outcomes of ICU patients based on the results of randomised controlled trials.

Music-based interventions and theoretical mechanisms in post-ICU survivors: A critical narrative synthesis.

Background: Hospitalization in the ICU can have long-term physiological and psychological impacts, affecting functional recovery and quality of life of post-ICU patients. Despite systematic reviews showing the impact of music interventions on physiological and psychological outcomes in ICU patients, their applicability and effectiveness in the post-ICU context remain unclear.

Aim: This review aimed to summarize: a) the types and characteristics of music/sound of interventions used in the rehabilitation of ICU patients, b) evidence on the feasibility, safety and acceptability of sound and music interventions for post ICU survivors, c) the types of post-ICU outcomes explored and the effects of sound and music interventions on any type of outcome in post-ICU survivors, and d) potential mechanisms or theoretical frameworks underlying the effects of sound and music interventions.

A Neurobiological Framework for the Therapeutic Potential of Music and Sound Interventions for Post-Traumatic Stress Symptoms in Critical Illness Survivors.

Overview: Post traumatic stress disorder (PTSD) has emerged as a severely debilitating psychiatric disorder associated with critical illness. Little progress has been made in the treatment of post-intensive care unit (ICU) PTSD.

Aim: To synthesize neurobiological evidence on the pathophysiology of PTSD and the brain areas involved, and to highlight the potential of music to treat post-ICU PTSD.
