Abstract：
BACKGROUND: Stress in surgeons is well-known for its negative impact on neurocognition and surgical performance. Surgeons commonly use music for stress reduction, but its specific effects on neurosurgeons remain unclear. This study aims to investigate how listening to music during microsurgery affects neurocognitive (NC) functions, subjective anxiety, and stress levels in neurosurgeons.
METHODS: Conducted in 2 phases, the pilot phase involved 23 neurosurgeons completing a survey and rating compositions based on ragas of North Indian/Hindustani classical music for suitability during surgery. Five excerpts were selected for the main phase, which involved 3 neurosurgeons performing 16 surgeries, 8 with and 8 without music. Data collection included presurgery assessments of sleep, caffeine intake, subjective stress levels, perceived complexity of the surgery that was to be performed, and NC tasks. Postsurgery subjective stress levels, actual complexity, and surgeon experiences with music were recorded.
RESULTS: While there was a trend toward reduced stress and perceived complexity with music, statistical significance was not reached. NC tasks showed nonsignificant improvement with music, with a significant (at P < 0.001) speed-accuracy trade-off noted in response inhibition.
CONCLUSIONS: Music appears to reduce subjective stress and task complexity, influencing neurocognition, particularly through speed-accuracy trade-offs. Further research is needed to understand its mechanisms and appropriate contexts for use before widespread recommendation.

摘要：
背景：外科医生的压力因其对神经认知和手术表现的负面影响而闻名。外科医生通常使用音乐来减轻压力，但其对神经外科医生的具体影响尚不清楚。这项研究旨在调查在显微外科手术期间听音乐如何影响神经认知功能，主观焦虑，和神经外科医生的压力水平。
方法：分两个阶段进行，试验阶段涉及23名神经外科医生,他们完成了一项调查,并根据北印度/印度斯坦古典音乐的ragas对作品在手术中的适用性进行评级.主要阶段选择了五个摘录，其中包括三名神经外科医生进行16次手术，八个有音乐，八个没有音乐。数据收集包括术前睡眠评估，咖啡因摄入量，主观压力水平，感知到要进行的手术的复杂性，和神经认知任务。手术后的主观压力水平，实际复杂性，记录了外科医生在音乐方面的经验。
结果：虽然音乐有减少压力和感知复杂性的趋势，没有达到统计学意义。神经认知任务显示音乐没有显着改善，在反应抑制中注意到显著的(p<0.001)速度-准确度权衡。
结论：音乐似乎可以减少主观压力和任务复杂性，影响神经认知，特别是通过速度-精度权衡。在广泛推荐之前，需要进一步研究以了解其机制和适当的使用环境。
