Background.The aim of this study was to investigate the effects of listening to Tibetan music on anxiety and endocrine, autonomic,\ncognitive responses in patients waiting for urologic surgery. Methods. Sixty patients waiting for surgery were enrolled to the study.\nThey were randomized in music (M) and control (C) groups. The M group listened to a low-frequency Tibetan music for 30 min\n(T0ââ?¬â??T30) through headphones, and the C group wore headphones with no sound. The State Trait Anxiety Inventory Questionnaire\n(STAI) Y-1 was administered at T0 and T30. Normalized low (LFnu) and high frequencies (HFnu) of heart rate variability, LF/HF\nratio, and galvanic skin response (GRS) data were analyzed at T0, T10, T20, T30, and T35.The salivary Ã?±-amylase (sAA) samples were\ncollected at T0, T35, and T45. Results. In the M group, the STAI Y-1 score decreased at T30 versus baseline (p < 0.001), sAA levels\ndecreased at T35 versus T0 (p 0.004), and GSR remained unchanged. In the C group, the STAI Y-1 score remained unchanged,\nsAA level increased at T35 versus T0 (p < 0.001), and GSR slightly increased at T35 versus baseline (p 0.359). LFnu was lower,\nand HFnu was significantly higher (T10ââ?¬â??T30) inMversus C group. Mean LF/HF ratio slightly reduced in theMgroup. Conclusions.\nOur results suggest that preoperative listening to relaxing Tibetan music might be a useful strategy to manage preoperative anxiety.
