Primary Outcome Measures:

  • cardiac monitoring [ Time Frame: through study period (to 15 min before the application of headphones until 15 minutes after their removal ]

    cardiac variability

Secondary Outcome Measures:

  • questionnaire [ Time Frame: questionnaire score change 15 min after the removal of headphones from baseline ( early before the application of headphones) ]

    anxiety questionnarie

  • laboratory test [ Time Frame: enzyme level change early after the application of headphones from baseline (early before the application of headphones) ]

    enzyme dosage

Patients undergoing elective surgical intervention will be allocated in two groups: Group M will listen prerecorded music through an individual headset for 30 min before the induction of anesthesia; Group C will listen no sound through an individual headset for 30 min before the induction of anesthesia The degree of stress and anxiety the patients will be assessed using questionnaire. Laboratory enzymes will be measured.

Heart rate, non invasive arterial pressure, pulse oximetry,skin resistance will be recorded. All the patients will receive continuous ECG holter recording .

To assess the effect of music therapy on the degree of autonomic modulation, HRV will be analyzed with traditional time and frequency measures.
