Surgeons perform complex tasks while exposed to multiple distracting sources that may increase stress in the operating room (e.g., music, conversation, and unadapted use of sophisticated technologies). This study aimed to examine whether such realistic social and technological distracting conditions may influence surgical performance.
Twelve medical interns performed a laparoscopic cholecystectomy task with the Xitact LC 3.0 virtual reality simulator under distracting conditions (exposure to music, conversation, and nonoptimal handling of the laparoscope) versus nondistracting conditions (control condition) as part of a 2 x 2 within-subject experimental design.
Under distracting conditions, the medical interns showed a significant decline in task performance (overall task score, task errors, and operating time) and significantly increased levels of irritation toward both the assistant handling the laparoscope in a nonoptimal way and the sources of social distraction. Furthermore, individual differences in cognitive style (i.e., cognitive absorption and need for cognition) significantly influenced the levels of irritation experienced by the medical interns.
The results suggest careful evaluation of the social and technological sources of distraction in the operation room to reduce irritation for the surgeon and provision of proper preclinical laparoscope navigation training to increase security for the patient.
外科医生在手术室中会面临多种分散注意力的源，这些源可能会增加他们的压力，例如音乐、对话和不适应使用复杂技术。本研究旨在探讨这种现实的社会和技术干扰条件是否会影响手术表现。
12 名实习医生在 Xitact LC 3.0 虚拟现实模拟器下进行腹腔镜胆囊切除术任务，在干扰条件下（暴露于音乐、对话和腹腔镜的非最佳处理）与非干扰条件（对照条件）下进行 2 x 2 被试内实验设计。
在干扰条件下，实习医生的任务表现（总任务评分、任务错误和操作时间）显著下降，并且对非最佳处理腹腔镜的助手和社会干扰源的刺激水平显著增加。此外，认知风格的个体差异（即认知吸收和认知需求）显著影响实习医生的刺激水平。
结果表明，应仔细评估手术室中的社会和技术干扰源，以减少对外科医生的刺激，并提供适当的临床前腹腔镜导航培训，以增加患者的安全性。
