Brief Summary

Intravenous (IV) ketamine is a treatment option for patients with chronic pain that does not respond to standard therapies, primarily working by blocking NMDA receptors in the brain. Beyond pain relief, ketamine can produce dissociative sensations, classifying it as an atypical psychedelic or mind-altering drug, and may enable patients to reprocess their pain similarly to experiences with traditional psychedelics. At the Montreal General Hospital's pain clinic, the investigators have observed patients frequently listening to music during ketamine infusions, and recent research indicates that music-especially when self-selected by patients-might provide additional pain-relieving benefits by influencing central mechanisms related to pain perception and interpretation. This intersection of music and pain relief is garnering substantial scientific interest as recent advances provide more insight into the neuroscience of music and its effects on brain regions involved in emotion, sensation, memory, and pain. This study aims to investigate the effects of music on chronic pain patients undergoing IV ketamine infusions at the Alan Edwards Pain Management Unit (AEPMU), specifically to determine whether the choice of music affects the intensity and duration of ketamine-induced pain relief. During the infusion (lasting 1 hour), patients will listen to a playlist delivered through specialized headphones, which will either consist of their own selected music (preferred music), music chosen by a music therapist, or no music at all, in a randomized order. Patients will track their pain levels throughout the infusion period and in the intervals between treatments (5 weeks) using standardized pain assessment tools. Additionally, the investigators will assess the subjective experiences of ketamine through interviews and qualitative analysis, while documenting and summarizing any adverse effects. The investigators hypothesize that listening to preferred music will enhance both the intensity and duration of pain relief from IV ketamine. To test this, the investigators will recruit patients already receiving repeated IV ketamine infusions for pain management at the AEPMU clinic. The first infusion will take place under usual conditions to establish a baseline. The infusions will occur in a dedicated room equipped with audio technology to ensure an immersive music experience.

Outcome Measures

Primary Outcomes (1)

  • Pain intensity

    Pain intensity assessed using a 0-10 visual rating scale anchored at 0 (absence of pain) and 10 (maximum pain imaginable). Participants will rate their average pain intensity in the previous 24 hours.

    From baseline to 24 hours after each ketamine session

Secondary Outcomes (9)

  • In-session Pain intensity

    Immediately before and after each ketamine session

  • In-session Pain unpleasantness

    Immediately before and after each ketamine session

  • Duration of pain relief

    From baseline to the end of each condition (5 weeks) daily for one week, then weekly

  • Brief Pain Inventory (pain interference)

    From baseline to the end of each condition (5 weeks)

  • Brief Pain Inventory (number of pain sites)

    From baseline to the end of each condition (5 weeks)

  • +4 more secondary outcomes

Interventions

The self-selected preferred music intervention will expose participants to music chosen based on personal tastes. Patients will be instructed to compile a playlist lasting approximately 1 hour, but preferably over 1 hour (to avoid repetition or moments without music) of their favorite music. They will be instructed to select songs that they find extremely pleasurable to listen to. Participants will be instructed to select songs that will have a higher likelihood to facilitate relaxation and introspection. This does not need to be an all-time favorite selection, but rather the music that they currently enjoy listening to the most.

The therapist-selected music intervention will expose participants to a curated playlist specifically designed for psychedelic treatment by expert Music Therapists, which was used in a previous study to investigate the additive hemodynamic effects of music during ketamine infusions for depression. Patients will be randomly exposed to one of 9 available playlists, all containing songs without lyrics.

SilenceOTHER

The silence intervention will expose patients to the same therapeutic procedures, in the same room and context, and with the same noise-cancelling headphones. The purpose is to cancel any potentially perturbing background noise, as no music will be played.
