Exploring the impact of music on response to ketamine/esketamine: A scoping review.

Music and ketamine each influence therapeutic outcomes, yet their combined use is rarely studied. This scoping review maps existing research on administering music alongside ketamine or esketamine in humans. Studies include healthy volunteers and patients of various ages, using different doses and treatment processes, with music played at varying times relative to drug administration. Research on music during ketamine anesthesia is included, as anesthesia drove early ketamine use. Recreational ketamine studies are excluded. The review is limited to English-language articles with no year restriction. It is the first comprehensive overview of music and ketamine/esketamine interplay, offering guidance for future study design.

Abstract

Music and ketamine are both known to affect therapeutic outcomes, but few studies have investigated their co-administration. This scoping review describes the existing literature on the joint use of music and ketamine-or esketamine (the S(+) enantiomer of ketamine)-in humans. The review considers that extant studies have explored the intersection of ketamine/esketamine and music in healthy volunteers and in patients of various age groups, at different dosages, through different treatment processes, and have varied the sequence of playing music relative to ketamine/esketamine administration. Studies investigating the use of music during ketamine anesthesia are also included in the review because anesthesia and sedation were the early drivers of ketamine use. Studies pertaining to recreational ketamine use were omitted. The review was limited to articles published in the English language but not restricted by publication year. To the best of our knowledge, this scoping review is the first comprehensive exploration of the interplay between music and ketamine/esketamine and offers valuable insights to researchers interested in designing future studies.
