Music is a low-cost intervention that can improve patient satisfaction.
This was a prospective, randomised, controlled trial conducted at an urban tertiary care academic medical centre in the United States. Nulliparous women 18-50 years old with a healthy singleton pregnancy at ≥ 37 weeks gestational age undergoing elective caesarean delivery under neuraxial anaesthesia were randomised to the music group (Mozart sonatas) or control group (no music). Mozart sonatas were broadcast to the music group immediately prior to patient entry and maintained throughout the procedure. The primary outcome was patient satisfaction using the Maternal Satisfaction Scale for Caesarean Section (MSSCS). Secondary outcomes were changes in anxiety pre- and post-operatively and post-operative mean arterial pressure (MAP). Student's t-test, the Wilcoxon rank sum test, and the c2 test were used where appropriate for statistical analyses.
27 parturients were evaluated for participation between 2018 and 2019, and 22 enrolled. The final study subject number was 20 due to two withdrawals. There were no clinically meaningful differences in baseline demographics, vital signs, and anxiety. The mean (SD) total patient satisfaction for music vs. control was 116 (16) vs. 120 (22), mean difference 4 (95% CI: -14.0 to 22.0), P = 0.645. The mean (SD) change in anxiety with music vs. control was 2.7 (2.7) vs. 2.5 (2.6), mean difference -0.4 (95% CI: -4.0 to 3.2), P = 0.827. The median (IQR) post-operative MAP with music vs. control was 77.7 (73.7-85.3) vs. 77.3 (72.0-87.3), P = 0.678.
The use of Mozart sonatas did not result in improvements in patient satis-faction, anxiety or MAP in parturients undergoing elective caesarean delivery.
音乐是一种低成本的干预手段，可以提高患者满意度。
这是一项在美国一家城市三级保健学术医疗中心进行的前瞻性、随机、对照试验。纳入年龄在 18-50 岁、孕龄≥37 周、行择期椎管内麻醉下剖宫产术的单胎、初产妇，按照 1:1 比例随机分为音乐组（莫扎特奏鸣曲）或对照组（无音乐）。在患者进入手术室前即刻开始向音乐组播放莫扎特奏鸣曲，并在整个手术过程中持续播放。主要结局指标是采用剖宫产产妇满意度量表（MSSCS）评估的患者满意度。次要结局指标为手术前后焦虑评分的变化以及术后平均动脉压（MAP）。统计学分析采用学生 t 检验、Wilcoxon 秩和检验和 c2 检验。
2018 年至 2019 年期间共评估了 27 名产妇参与研究的可能性，其中 22 名产妇入组。由于 2 名产妇退出研究，最终的研究对象为 20 名产妇。音乐组与对照组在基线人口统计学特征、生命体征和焦虑评分方面无临床意义差异。音乐组与对照组产妇的总满意度评分分别为 116（16）分和 120（22）分，平均差值为 4 分（95%CI：-14.0 至 22.0），P=0.645。音乐组与对照组产妇的焦虑评分变化分别为 2.7（2.7）分和 2.5（2.6）分，平均差值为-0.4 分（95%CI：-4.0 至 3.2），P=0.827。音乐组与对照组产妇的术后 MAP 中位数（IQR）分别为 77.7（73.7-85.3）mmHg 和 77.3（72.0-87.3）mmHg，P=0.678。
在择期剖宫产产妇中，使用莫扎特奏鸣曲并未改善患者满意度、焦虑评分或 MAP。
