    Background: Peri-operative anxiety is a common entity that can present as a challenge to the anaesthetist and can also negatively affect the surgical outcome and functional recovery. The use of music in a medical setting is becoming increasingly popular. Literature indicates promising outcomes on the use of music to reduce anxiety. The aim of this study was to determine the effects of listening to music, on patients’ anxiety, during spinal anaesthesia for patients undergoing knee and hip arthroplasty in a South African context. Materials and methods: This randomised, controlled study included 58 adult patients scheduled to receive lower limb arthroplasty surgery. Patients in the intervention group (music group) received one of five genres of music via headphones. The control group did not receive music. Both groups received a standardised neuraxial anaesthetic. Patients’ anxiety in both groups were measured using a visual analogue scale for anxiety (VAS-A). Anxiety scores were measured at the pre-operative visit, the morning prior to surgery, at skin incision and in the post-anaesthesia care unit. Results: Each group contained 29 patients. There was no difference in the baseline anxiety scores recorded at the pre-operative visit between the two groups (1.8 cm vs 1.9 cm; p = 0.422). The anxiety scores were significantly lower in the music group compared to the control group at skin incision (0.9 cm vs 1.9 cm; p < 0.001). The music group also experienced a greater decrease in their anxiety from prior to surgery to skin incision (1.4 cm vs 0.2 cm; p = 0.002). Conclusion: Music is an effective, cheap, safe, non-pharmacological adjunct that can be used to reduce peri-operative anxiety in patients undergoing lower limb arthroplasty procedures under spinal anaesthesia.
