HealthDay News — Listening to recorded music is associated with a significant reduction in anxiety and pain following cardiac surgery, according to a review published online in Open Heart.

Ellaha Kakar, from Erasmus Medical Center in Rotterdam, Netherlands, and colleagues conducted a systematic literature search and meta-analysis of randomized controlled trials evaluating music interventions in cardiac surgery.

Based on 20 eligible studies for qualitative analysis (1169 patients) and 16 studies for meta-analysis (987 patients), the researchers found that the first postoperative music session was associated with significantly reduced postoperative anxiety and pain. There were reductions of 4.00 points on the State-Trait Anxiety Inventory and 1.05 points on the Visual Analogue Scale/Numeric Rating Scale for anxiety and a reduction of 1.26 points on the Visual Analogue Scale/Numeric Rating Scale for pain. Multiple days of music intervention were associated with reduced anxiety until 8 days postoperatively.
