目的:探讨高仿真模拟支气管镜模拟技术在呼吸科专科医师支气管镜操作训练中的作用。方法:对20名呼吸科医生(支气管镜检查术的初学者)作为观察对象,采用美国生产的Simbionix GI Mentor Simulator高仿真模拟支气管镜操作系统进行培训。由2名熟练进行支气管镜检查术的呼吸科医生进行指导,比较培训前后在高仿真模拟支气管镜操作的速度、灵活性和准确性方面差异。结果:20名初学者均完成了支气管镜的操作培训。在模拟训练后,操作的灵活性、准确性和速度都明显提高。与训练前相比视野清晰可见时间由(30.0±2.0)%增加到(75.0±5.0)%:段支气管检查到达由(74.0±5.1)%提高到(89.3±4.0)%;通过咽喉及声门时间由(00.01.28±00.00.54)h缩短到(00.00.36±00.00.09)h,操作用时由(00.07.27±00.01.23)h缩短到(00.06.24±00.00.54)h。误入食道次数由(6.0±2.0)缩短到(2.0±0.5),培训前机器给予自动评分为(30.8±6.6)分,培训后(70.8±6.6)分。结论:高仿真模拟支气管镜在初学气管镜呼吸专科医师培训中起到重要的作用。
Objective: To explore the role of high simulation simulated bronchoscopy in bronchoscopic training of respiratory specialists. METHODS: Twenty respiratory physicians (beginners of bronchoscopy) were selected as subjects for training using the Simbionix GI Mentor Simulator high-simulation simulated bronchoscope operating system manufactured in the United States. Two respiratory surgeons who were proficient with bronchoscopy were instructed to compare the speed, agility and accuracy of high simulation simulated bronchoscopy before and after training. Results: 20 beginners completed the operation training of bronchoscope. After the simulation training, the flexibility, accuracy and speed of operation are obviously improved. Compared with pre-training, the time of visual field increased from (30.0 ± 2.0)% to (75.0 ± 5.0)%: the degree of segment bronchus increased from (74.0 ± 5.1)% to (89.3 ± 4.0)%; The time was shortened from (00.01.28 ± 00.00.54) h to (00.00 ± 36.00 ± 0.09) h and the operation time was shortened from (00.07.27 ± 00.01.23) h to (00.06.24 ± 00.00.54) h . The number of missed esophageal passages was shortened from (6.0 ± 2.0) to (2.0 ± 0.5), and the score was (30.8 ± 6.6) minutes before training and 70.8 ± 6.6 minutes after training. Conclusion: High simulation simulated bronchoscopy plays an important role in the training of beginner tracheal respiration specialist.
