Cast room procedures, such as cast application and removal, pin removal, and suture removal can cause significant anxiety in young children. The use of music therapy in the cast room to decrease anxiety has not been previously reported.
We performed a randomized, prospective study of soft lullaby music compared with no music in 69 children 10 years or younger undergoing cast room procedures. Heart rates (beats per minute) were recorded in the waiting room and cast room using a pulse oximeter.
A total of 28 children were randomized to music and 41 children to no music. The mean rise in heart rate between the waiting room and entering the cast room was -2.7 beats/min in the music group and 4.7 beats/min in the no music group (P = 0.001). The mean difference in heart rate between the waiting room and during the procedure was 15.3 beats/min in the music group and 22.5 beats/min in the no music group (P = 0.05). There were 7 patients in the no music group with heart rate increases of greater than 40 beats/min. No patient in the music group had an increase of this magnitude.
Playing soft music in the cast room is a simple and inexpensive option for decreasing anxiety in young children during cast room procedures.

石膏室操作，如石膏的应用与拆除、钢针拔除及缝线拆除，会使幼儿产生显著焦虑。此前尚无关于在石膏室使用音乐疗法减轻焦虑的报道。
我们对69名10岁及以下接受石膏室操作的儿童进行了一项随机前瞻性研究，比较了轻柔摇篮曲音乐与无音乐的效果。使用脉搏血氧仪在候诊室和石膏室记录心率（每分钟心跳次数）。
共有28名儿童被随机分配到音乐组，41名儿童被分配到无音乐组。音乐组从候诊室到进入石膏室时心率的平均上升为 -2.7次/分钟，无音乐组为4.7次/分钟（P = 0.001）。音乐组从候诊室到操作过程中心率的平均差异为15.3次/分钟，无音乐组为22.5次/分钟（P = 0.05）。无音乐组有7名患者心率增加超过40次/分钟。音乐组没有患者心率增加达到这一程度。
在石膏室播放轻柔音乐是在石膏室操作期间减轻幼儿焦虑的一种简单且经济的方法。
随机临床试验，二级。
