Acoustic conditions in the operating room have different impacts on surgeon's performance. Their effects on the performance of surgical teams are not well documented. We investigated if laparoscopic teams operating under pleasant acoustic conditions would perform better than under noisy conditions.
We recruited 114 surgical residents and built 57 two-person teams. Each team was required to perform two laparoscopic tasks (object transportation and collaborative suturing) on a simulation training box under music, neutral, and noisy acoustic conditions. Data were extracted from video recordings of each performance for analysis. Task performance was measured by the duration of time to complete a task and the total number of errors, and objective performance scores. The measures were compared over the three acoustic conditions.
A music environment elicited higher performance scores than a noisy environment for both the object transportation (performance score: 66.3 ± 8.6 vs. 57.6 ± 11.2; p < 0.001) and collaborative suturing tasks (78.6 ± 5.4 vs. 67.2 ± 11.1; p < 0.001). Task times in the music and noisy environments was subtracted to produce a music-noisy difference time. Pearson correlation coefficient analysis showed a significant negative relationship between the team experience score and the music-noisy difference time on the object transportation (r = - 0.246, p = 0.046) and collaborative suturing tasks (r = - 0.248, p = 0.044).
As to individuals, music enhances the performance of a laparoscopy team while a noisy environment worsens performance. The negative correlation between team experience and music-noisy difference time suggests that laparoscopy teams composed of experienced surgeons are less likely affected by an acoustic distraction than the noisy teams. Team resistance to acoustic distraction may lead to a new way for assessing team skills.
手术室中的声学条件对外科医生的表现有不同的影响。但它们对手术团队表现的影响并没有得到很好的记录。我们研究了在舒适的声学条件下进行手术的腹腔镜团队是否会比在嘈杂的环境下表现得更好。
我们招募了 114 名外科住院医师，并组建了 57 个两人团队。每个团队都需要在模拟训练箱上完成两个腹腔镜任务（物体运输和协作缝合），在音乐、中性和嘈杂的声学条件下进行。从每个表现的视频记录中提取数据进行分析。任务表现通过完成任务的时间和总错误数以及客观表现分数来衡量。在三种声学条件下比较了这些措施。
与嘈杂环境相比，音乐环境下物体运输（表现得分：66.3±8.6 对 57.6±11.2；p<0.001）和协作缝合任务（表现得分：78.6±5.4 对 67.2±11.1；p<0.001）的表现得分更高。音乐和嘈杂环境下的任务时间相减得出音乐-嘈杂差异时间。Pearson 相关系数分析显示，物体运输（r=-0.246，p=0.046）和协作缝合任务（r=-0.248，p=0.044）中团队经验评分与音乐-嘈杂差异时间之间存在显著负相关。
对于个体而言，音乐可以提高腹腔镜团队的表现，而嘈杂的环境会降低表现。团队经验与音乐-嘈杂差异时间之间的负相关表明，由经验丰富的外科医生组成的腹腔镜团队比嘈杂的团队受到声学干扰的影响更小。团队对声学干扰的抵抗力可能为评估团队技能提供一种新方法。
