目的证明虚拟现实（VR）培训将技术技能转移到手术室（OR）环境中。摘要背景数据的使用。 VR 手术模拟训练技能和降低手术室错误风险的作用从未在前瞻性、随机、盲法研究中得到证实。方法对 16 名外科住院医师 (PGY 1-4) 进行了基线精神运动能力评估，然后随机接受 VR 训练（MIST VR 模拟器透热任务），直至达到由经验丰富的腹腔镜医师制定的专家标准水平 (n = 8)，或未接受 VR 训练的对照组 (n = 8)。所有受试者均在不知情的主治外科医生的培训下进行腹腔镜胆囊切除术。胆囊解剖的录像由两名对受试者身份和培训不知情的研究人员独立审查，并对每个手术分钟的八个预定义错误进行评分（错误评估的评估者间可靠性 r > 0.80）。结果组间未发现基线评估存在差异。经过 VR 培训的住院医师的胆囊解剖速度加快了 29%。未接受过 VR 培训的居民暂时无法取得进展的可能性是其他人的九倍（P
ObjectiveTo demonstrate that virtual reality (VR) training transfers technical skills to the operating room (OR) environment.Summary Background DataThe use. of VR surgical simulation to train skills and reduce error risk in the OR has never been demonstrated in a prospective, randomized, blinded study.MethodsSixteen surgical residents (PGY 1-4) had baseline psychomotor abilities assessed, then were randomized to either VR training (MIST VR simulator diathermy task) until expert criterion levels established by experienced laparoscopists were achieved (n = 8), or control non-VR-trained (n,= 8). All subjects performed laparoscopic cholecystectomy with an attending surgeon blinded to training status. Videotapes of gallbladder dissection were reviewed independently by two investigators blinded to subject identity and training, and scored for eight predefined errors for each procedure minute (interrater reliability of error assessment r > 0.80).ResultsNo differences in baseline assessments were found between groups. Gallbladder dissection was 29% faster for VR-trained residents. Non-VR-trained residents were nine times more likely to transiently fail to make progress (P
