摘要

本研究採單組前後測之研究設計，主要目的為評值東方舒緩音樂聆聽介入措施對等待正子斷層掃瞄檢查病人情境焦慮及心率變異之生理指標的影響。以立意取樣選取25位符合收案條件之預計接受正子斷層掃瞄檢查病人。每位研究個案在等待室時先接受前測情境焦慮量表（Spielberger Trait Anxiety Inventory-State, STAI-S）的評估。除了原本檢查前例行常規準備流程之外，研究個案於安靜的等待室躺於檢查床上等待時，聆聽東方舒緩音樂30 分鐘，於40 分鐘的等待過程，使用藍芽無線生理監測儀監測其心跳及心率變異之變化，之後再接受情境焦慮量表之後測評估。本研究發現等待正子斷層掃瞄檢查病人有低至中等程度的焦慮。在聆聽東方舒緩音樂後，其主觀情境焦慮程度（p=0.002）及平均心跳（p<0.001）顯著地下降，達到放鬆的狀態。此音樂雖然增加心率變異之高頻百分比，使其趨於放鬆，但此增加未達顯著差異（p>0.05）。舒緩音樂的聆聽措施為一經濟方便的措施且能降低病人在等待檢查過程中的主觀焦慮程度，建議未來以較大樣本數及實驗研究設計來評值此東方舒緩音樂的聆聽措施對心率變異生理相關指標之成效。東方舒緩音樂的聆聽為一不具侵入性且方便的介入措施，能在臨床中推廣，可協助降低正子斷層掃瞄檢查病人在等待期間的焦慮程度及降低其心理及生理上的不適，進而促進檢查的流程。

Abstract

This study used a one-group pre-test and post-test design to evaluate the effects of eastern soothing music listening on state anxiety and heart rate variability in patients awaiting positron emission tomography (PET) scans. A purposive sample of 25 eligible patients scheduled for PET scans were recruited. Each participant received baseline assessment for state anxiety using Spielberger Trait Anxiety Inventory-State (STAI-S) when they waited in the waiting room. In addition to the routine procedure of PET scanning preparation, the participants listened to 30 minutes of eastern soothing music individually while they lied on the examination table in the quite waiting room. During the 40 minutes of waiting time, the participant was monitored for their heart rate variability using Bluetooth wireless physiological monitor. All participants were assessed for their state anxiety again at post-test. This study found that patients awaiting PET scans had low to medium level of state anxiety. After listening to eastern soothing music, the participants’ subjective state anxiety (p=0.002) and mean heart rates (p<0.001) were significantly reduced, indicating they were in a relaxing state. This music listening increased the participants’ HF % of heart rate variability which indicated being in a relaxing state, but the increase was not significant (p>0.05). Eastern soothing music listening as a non-invasive and convenient strategy can be used in the clinical setting and can help reduce anxiety in order to and alleviate physical and psychological discomfort of patients awaiting PET scans and facilitate the examination procedures.
