背景：以往的研究探讨了疲劳对一般心理能力的影响。然而，研究专门解决疲劳对外科住院医师的认知技能的影响，在模拟surgical exercises.Methods：37外科住院医师在precall和postcall条件进行了测试，心理和认知技能评估的虚拟现实模拟器与触觉反馈和手部动作记录。为了评估手术技能，分析了手和工具运动的平滑度、认知错误和完成特定任务的时间。（P <0.01）记录在熟练度变量的记忆，注意力，和联运协调任务时，居民在postcall条件。疲劳和睡眠剥夺导致外科住院医师的认知技能显着恶化，通过虚拟现实模拟测量。在需要心理和认知技能相结合的任务中，心理技能也会受到负面影响。(C)2008 Excerpta Medica Inc.

Background: Previous studies have explored the effect of fatigue on general psychomotor proficiency. However, studies specifically addressing the effect of fatigue on surgical residents' cognitive skills during simulated surgical exercises are lacking.Methods: Thirty-seven surgical residents in both the precall and the postcall condition were tested for psychomotor and cognitive skill evaluation on a virtual-reality simulator with haptic feedback and hand-motion recording. To evaluate surgical skills, hand- and tool-movement smoothness, cognitive errors, and time to completion for specific tasks were analyzed.Results: In addition increased cognitive errors, a significant decrease (P < .01) was recorded in the proficiency variables of memory, attention, and intermodal coordination tasks when residents were in the postcall condition.Conclusions: Fatigue and sleep deprivation cause a significant deterioration in the surgical residents' cognitive skills as measured by virtual reality simulation. Psychomotor skills are also negatively impacted during tasks that require a combination of psychomotor and cognitive skills. (C) 2008 Excerpta Medica Inc. All rights reserved.
