机械通气患者实施音乐干预的随机对照研究

Music intervention on mechanically ventilated patients：a randomized control trial

目的探讨音乐干预降低机械通气患者焦虑水平以及稳定机械通气患者生理指标的效果。方法将150例机械通气患者随机分为音乐组、耳机组、空白组，采用中国版状态焦虑量表（C-SAI）对三组研究对象干预前后的焦虑水平进行测定，同时记录心率、呼吸率和血压。结果干预后音乐组C-SAI评分（40．54±8．34）分，耳机组（47．52±9．25）分，空白组（52．02±10．20）分，三组患者干预前后比较差异均有统计学意义（P〈0．01）；音乐组患者干预前后心率、呼吸率、收缩压和舒张压的变化均有统计学意义（P〈0．01）。结论音乐干预与戴耳机均有降低机械通气患者焦虑水平的作用，且音乐的作用更明显，音乐可以稳定机械通气患者心率、呼吸率、收缩压和舒张压。

Objective To examine the effects of music intervention on the physiological variables and the anxiety level of mechanically ventilated patients. Methods A total of 150 patients with mechanical ventilation were randomly divided into the music group, the headphone group and the control group. The patients were investigated by using the C-STAI scale before and after the study .period. The indicators including heart rate, respiratory rate, saturation of oxygen and blood pressure were recorded before and after the study period. Results Significant differences were found in state anxiety before and after the test in music group and headphone group （P 〈 0. 01 ）. The difference （ post-pre ） of state anxiety within three groups revealed significant differences （ P 〈 0. 01 ）. Significant differences were found on HR, RR, SBP and DBP before and after the test in music group （P 〈0. 01 ）. Condusions Music and headphone can reduce anxiety in mechanically ventilated patients and the effects of the former are better. Music can steady the heart rate, saturation of oxygen and blood pressure for patients with mechanical ventilation.
