Music is commonly played in operating theaters. Some surgeons believe music reduces stress and operative time, while others think music is a distraction and should be avoided. There is limited published evidence evaluating the effects of music on surgical performance.
The goal of this study is to evaluate the effect of music on simple wound closure.
Plastic surgery residents were asked to perform layered closures on pigs' feet with and without their preferred music playing. Simple randomization was used to assign residents to the music playing first or music playing second group. The time to complete the repair was measured and repairs were graded by blinded faculty. Results were analyzed to determine significant differences in time to complete the task and quality of repair. Participants were retested in a second session with music played in the opposite order to evaluate consistency.
Listening to preferred music decreased repair time by 8% for all plastic surgery residents (p = 0.009). Subgroup analysis demonstrated even more significant improvement in speed for senior residents (PGY 4-6), resulting in a 10% decrease in repair time (p = 0.006). The quality of repair was also better in the music group, at 3.3 versus 3.1 (p = 0.047). Retesting revealed results remained significant whether music was played first or second.
Playing preferred music made plastic surgery residents faster in completing wound closure with a 10% improvement in senior residents. Music also improved quality of repair as judged by blinded faculty. Our study showed that music improves efficiency of wound closure, which may translate to healthcare cost savings.
手术室中通常会播放音乐。一些外科医生认为音乐可减轻压力并缩短手术时间,而另一些人则认为音乐会分散注意力,应予以避免。关于音乐对外科手术表现影响的已发表证据有限。
本研究的目的是评估音乐对简单伤口缝合的影响。
要求整形外科住院医师在有和没有播放其喜欢的音乐的情况下对猪脚进行分层缝合。采用简单随机化方法将住院医师分配到先播放音乐组或后播放音乐组。测量完成修复的时间,并由不知情的教员对修复进行评分。分析结果以确定完成任务的时间和修复质量的显著差异。在第二阶段,以相反的顺序播放音乐对参与者进行重新测试,以评估一致性。
所有整形外科住院医师在听喜欢的音乐时,修复时间减少了8%(p = 0.009)。亚组分析表明,高级住院医师(PGY 4 - 6)的速度提升更为显著,修复时间减少了10%(p = 0.006)。音乐组的修复质量也更好,评分为3.3,而另一组为3.1(p = 0.047)。重新测试显示,无论音乐是先播放还是后播放,结果仍然显著。
播放喜欢的音乐使整形外科住院医师在完成伤口缝合时速度更快,高级住院医师的速度提高了10%。音乐也提高了不知情教员评判的修复质量。我们的研究表明,音乐提高了伤口缝合的效率,这可能转化为医疗成本的节省。
