Abstract：
UNASSIGNED: Traditional apprenticeship-based surgical training presents with challenges, especially in acute scenarios. Simulation provides the current standard of facilitating surgical training in a low-risk environment but is restricted by limited accessibility and high costs. Virtual reality (VR) offers immersive three-dimensional computer-generated training scenarios and can connect users from various locations. We aimed to compare the performance of junior doctors to manage an acute surgical scenario using VR and mannequin-based simulation. We hypothesised that VR would be as effective as mannequin-based simulation in performance outcomes.
UNASSIGNED: This multicentre, randomised controlled pilot study was conducted with eighteen junior doctor volunteers (Foundation and Core Trainee Year 1). Ten were randomly allocated to VR and eight to mannequin-based simulation. Participants completed questionnaires and a 15-min pneumothorax scenario. Quantitative metrics included overall score, time-to-critical decisions, and academic buoyancy scores (ABS). Qualitative metrics included participants\' likes and dislikes of their allocated simulation modality.
UNASSIGNED: VR participants scored significantly higher than mannequin-based simulation participants in overall scores (74.30% (SD ± 5.08%) vs. 59.75% (SD ± 10.14) (p = 0.04)), and technical skills aspects (77.20% (SD ± 8.01%) vs. 65.00% (SD ± 8.21%) (p = 0.01)). Mannequin-based simulation participants initiated critical decisions faster and demonstrated a trend towards a faster mean time-to-completion (p = 0.06). ABS scores increased for both study groups, though was only significant for VR participants (p ≤ 0.01). VR participants liked how VR fostered independent learning but disliked the formulaic content and impaired communication-learning compared to mannequin-based simulation.
UNASSIGNED: Both VR and mannequin-based simulation training are effective in training junior doctors in acute surgical scenarios but present different educational benefits. Future research should recruit a larger sample size for a full comparative randomised controlled trial.

摘要：
■传统的以学徒制为基础的外科培训带来了挑战，尤其是在急性情况下。模拟提供了在低风险环境中促进手术训练的现行标准,但受到有限的可接近性和高成本的限制。虚拟现实（VR）提供了沉浸式的三维计算机生成的培训场景，可以连接来自不同位置的用户。我们旨在比较初级医生使用VR和基于人体模型的模拟来管理急性手术方案的表现。我们假设VR在性能结果上与基于人体模型的模拟一样有效。
■这个多中心，对18名初级医生志愿者(基础和核心培训生1年)进行了随机对照试点研究。十个被随机分配给VR，八个被随机分配给基于人体模型的模拟。参与者完成问卷和15分钟气胸情景。定量指标包括总分，关键决策的时间，和学术浮力分数（ABS）。定性指标包括参与者对他们分配的模拟模式的好恶。
■VR参与者的总分明显高于基于人体模型的模拟参与者（74.30%（SD±5.08%）与59.75%（SD±10.14）（p=0.04），和技术技能方面(77.20%(SD±8.01%)与65.00%(SD±8.21%)(p=0.01))。基于人体模型的模拟参与者更快地启动了关键决策，并表现出了更快的平均完成时间的趋势（p=0.06）。两个研究组的ABS评分都增加了，尽管仅对VR参与者显着（p≤0.01）。与基于人体模型的模拟相比，VR参与者喜欢VR如何促进独立学习，但不喜欢公式化的内容和受损的交流学习。
■VR和基于人体模型的模拟训练在急性手术场景中培训初级医生方面都有效，但具有不同的教育益处。未来的研究应该招募更大的样本量来进行完整的比较随机对照试验。
