Personalized Music and Dreaming During Propofol Sedation
Sponsor: Wonkwang University Hospital
Summary
Many patients report dreams during intravenous (IV) propofol sedation, but it is uncertain whether listening to music changes how often dreams occur or how pleasant they feel. This single-center randomized study compared three auditory conditions during propofol sedation for elective surgery under spinal anesthesia or peripheral nerve block: (1) patient-selected preferred music, (2) matched non-preferred music, and (3) silence (headphones only). Music or silence was delivered through identical closed-back headphones starting 1-2 minutes before sedation and continuing until the end of sedation. The main outcomes were (1) whether a dream occurred (yes/no) assessed by a neutral modified Brice interview in the post-anesthesia care unit (PACU), and (2) dream pleasantness rated on a 0-10 scale among participants who reported a dream. Additional outcomes included coded dream content features, patient satisfaction, sedative dose, hemodynamic variability, early recovery measures, postoperative symptoms, and adverse events.

Conditions
Interventions
Preferred Music
Standardized closed-back headphones are used to deliver music during IV propofol sedation. Depending on randomization, participants receive self-selected preferred music. Playback begins shortly before sedation and continues until the end of sedation; volume is calibrated per protocol.
Matched Non-Preferred Music
Standardized closed-back headphones are used to deliver music during IV propofol sedation. Depending on randomization, participants receive e matched non-preferred music. Playback begins shortly before sedation and continues until the end of sedation; volume is calibrated per protocol.
Silence (Headphones Only)
Participants wear identical closed-back headphones during IV propofol sedation, but no audio is played. Procedures, timing, and staff interactions are otherwise identical to the music arms.
