The Effects of Music Therapy on Patients Undergoing Colonoscopy in a Tertiary Care Hospital at Karachi, Pakistan: A Comparative Study.

A colonoscopy is a procedure commonly used for the diagnosis of colorectal diseases but may be associated with high levels of anxiety and discomfort, which can lead to complications during sedation and decreased patient comfort and cooperation. This study was conducted at a tertiary care hospital in Karachi to assess the effectiveness of music therapy on pre-procedural anxiety, sedation requirements, pain, and procedure duration among patients undergoing colonoscopies. This comparative study included 110 outpatients. The intervention arm received non-lyrical soft music through earphones before and during the colonoscopy procedure, while the control group did not receive any music. In the intervention arm, significant reductions were seen in pre-procedural anxiety scores (p < 0.001), physiological measures (p < 0.001), sedation doses (p < 0.001), and procedure durations (p < 0.05). Control arm showed an increase in heart rate and systolic blood pressure (p < 0.001). Pain scores were similar for both groups. Music therapy is an effective tool to reduce patient anxiety pre- procedure. It is a simple, safe, and noninvasive relaxing intervention that could be used as an adjunct to sedative medications before and during the colonoscopy procedure.
