Conclusion
• Music, both with and without BB:
– decrease anxiety level and lower – decrease anxiety level and lower systolic BP
• Patients who received BB:
– decrease in heart rate
• BB embedded musical intervention • BB embedded musical intervention may have benefit over musical intervention alone in decreasing operative anxiety
