Healthcare providers in the emergency first response units have been exposed to a considerable stress during the SARS-CoV-2 pandemic. This study was designed to identify the effects of listening to music during the work break compared to the routine break (in the absence of listening to music) on the level of state anxiety and on the vital parameters of the nurses on duty at the operations center.
Randomized, controlled, three-arm, double-blind, single-center clinical study. Healthcare providers were divided into three groups according to study intervention (Group 1: listening to 440Hz music; Group 2: listening to 432Hz music; Group 3: liberal activity). The study was conducted during the working hours of dayshifts in an emergency first response unit station located in Tuscany, Italy. Outcomes were measured against measures of stress (State-Trait Anxiety Inventory - STAIX1), heart rate (HR), respiratory rate (RR), systolic/diastolic blood pressure (SBP/DBP), pain and productivity (Likert Scale) measured at baseline (T0) and at the end of exposure (T1).
Overall, 54 healthcare providers were enrolled; 32 females (59.3%); mean age of 39.64 years (SD±9.94); the total measurements performed were 83. The median values of STAI X1 decreased in all the 3 groups from T0 to T1 (Group 1: 34.5 vs. 32, p=0.0001; Group 2: 34 vs. 29, p=0.001; Group 3: 33 vs. 31, p=0.028). In Group 2 a reduction of mean values of respiratory rate and systolic blood pressure was recorded at T1 (-2.714 b/min, p=0.000 and -3.821 mmHg, p=0.031, respectively).
Listening to music at 432 Hz is a low cost and short intervention that can be a useful resource to manage anxiety and stress. Further studies are needed to assess medium and long-term effects of listening to music.
在 SARS-CoV-2 大流行期间，急救一线的医护人员承受了相当大的压力。本研究旨在比较工作休息期间听音乐与常规休息（不听音乐）对值班护士的状态焦虑水平和生命体征的影响。
随机、对照、三臂、双盲、单中心临床研究。根据研究干预措施，医护人员分为三组（组 1：听 440Hz 音乐；组 2：听 432Hz 音乐；组 3：自由活动）。该研究在意大利托斯卡纳的一个急救一线站的白班工作时间进行。在基线（T0）和暴露结束时（T1），使用应激量表（状态-特质焦虑量表-STAIX1）、心率（HR）、呼吸频率（RR）、收缩压/舒张压（SBP/DBP）、疼痛和生产力（Likert 量表）来测量结果。
共有 54 名医护人员参与了研究，其中女性 32 名（59.3%），平均年龄 39.64 岁（标准差±9.94），共进行了 83 次测量。所有 3 组的 STAI X1 值中位数均从 T0 到 T1 降低（组 1：34.5 降至 32，p=0.0001；组 2：34 降至 29，p=0.001；组 3：33 降至 31，p=0.028）。在组 2 中，T1 时呼吸频率和收缩压的平均值均降低（每分钟减少 2.714 次，p=0.000，收缩压减少 3.821mmHg，p=0.031）。
听 432Hz 的音乐是一种低成本、短时间的干预措施，可以作为管理焦虑和压力的有用资源。需要进一步研究来评估听音乐的中、长期效果。
