基于虚拟现实技术的侧脑室穿刺模拟训练研究

摘要

目的 评估基于虚拟现实技术的侧脑室穿刺模拟演练系统对于年轻医师掌握侧脑室穿刺术的训练效果.方法 随机选择进入规范化住院医师培训工作的住院医师50名,接受基于虚拟现实技术的侧脑室穿刺模拟演练系统训练,持续4周.训练前后分别使用利克特量表进行效果评价.结果 经过模拟系统演练培训后,培训医师对侧脑室解剖理解评分(4.70±0.71)分,高于训练前(1.58±1.41)分,差异有统计学意义(t=893.9,P＜0.05);对于手术步骤掌握评分训练后(4.54±0.70)分,高于训练前(2.06±2.12)分,差异有统计学意义(t=365.39,P ＜0.05);脑室穿刺方向把握评分(4.7±0.71)分,高于训练前(1.34±1.02)分,差异有统计学意义(t=1206.12,P ＜0.05);独立真实操作自我评估(4.20±1.00)分,高于训练前(1.66±0.69)分,差异有统计学意义(t=365.39,P ＜0.05).尽管有28位(56％)医师对于系统给予的真实沉浸感并不认可,但是所有培训医师均表示同意或非常同意该模拟系统的有效性和仿真性.结论 基于虚拟现实技术的侧脑室穿刺模拟演练系统有助于年轻医师快速掌握侧脑室穿刺技能,是有效提高其专业素质水平的训练平台.%Objective To evaluate the training outcome of young doctors based on the virtual reality (VR) simulator for lateral ventricular puncture. Methods Fifty residents admitted to standardized residency training program were selected to receive the training with the VR simulator for lateral ventricular puncture. Results The score to evaluate the residents' cognition of lateral ventricular surgery improved significantly compared with the pre-training one [ (4.7±0.71) points v.s. (1.58±1.41) points, t=893.9, P ＜ 0.05) ]. The VR simulator allowed the participants to master more about operation process with statistical significance [ (4.54±0.70) points v.s. (2.06±2.12) points, t=365.39, P ＜ 0.05) ], and to achieve more exact direction of puncture[ (4.7±0.71) points v.s. (1.34±1.02) points, t=1206.12, P ＜ 0.05) ], as well as to acquire more self-confidence in real practice [ (4.20±1.00) points v.s. (1.66±0.69) points, t=365.39, P ＜ 0.05) ]. Although 28 (56％) residents claimed that the feeling of true immersion provided by the virtual reality simulator was not perfect, they all agree the simulator could improve training effectiveness and offer real feeling.Conclusion The virtual reality simulator provides young doctors with an effective platform to master the skill of lateral ventricular puncture rapidly, and thereby elevates their professionalism.
