Brain.fm Music for Anesthesia

Induction and emergence from propofol can be a difficult process for patients and healthcare workers, and long recovery times in particular can limit the rate of care. A double-blinded randomized controlled trial with 220 patients undergoing elective colonoscopy or endoscopy is proposed to test the impact of perioperative music on patient experience and recovery from propofol anaesthesia. Patients will be assigned at random to hear either rhythmic auditory stimulation (music designed to drive neural oscillations) or spectrally-matched noise (sound that produces the same levels of activity at the cochlea but not expected to drive neural entrainment). Bone-conduction headphones will be administered in pre-operation waiting and will play music (or matched noise) until propofol administration ceases, at which time the music (or noise) will be switched: Pre- and post-operational music is designed to be sedative and stimulative, respectively, created with methods that drive auditory entrainment to promote those states. Outcome measures will be recovery time and the patient's subjective experience (taken via survey).
