摘　　要：目的 探讨血管穿刺训练模型在介入超声教学中的应用及其学习曲线。方法 对2021年6月至2021年12月在北京大学第三医院超声科学习的14名进修医师进行培训及考核,分别绘制沿粗管长轴和短轴、细管长轴和短轴进针的平均时间学习曲线,并进行问卷调查。结果 沿粗管长轴穿刺的平均时间学习曲线在第4次出现拐点,之后逐渐趋于平稳,穿刺平均时间在19 s以内。沿粗管短轴、细管长轴和细管短轴练习10次均未出现拐点。问卷调查结果表明,大多数进修医师认为利用模型练习穿刺可以很大程度或较大程度上激发学习兴趣,提高独立操作信心,提高对所学超声介入知识的理解。结论 进修医师在经过超声介入理论培训、介入穿刺观摩和4次模型练习后,可基本掌握超声引导下沿粗管长轴穿刺置管,沿粗管短轴、细管长轴和短轴穿刺置管方面并不能达到稳定水平,需要更多练习机会。Objective To discuss the application of vascular puncture training model in the teaching of interventional ultrasound and to analyze its learning curve.Methods Training and assessment were conducted in the 14 refresher doctors who studied in the Department of Ultrasound of Peking University Third Hospital from June 2021 to December 2021.The learning curve of the average time spent for needle insertion along the long axis and short axis of thick tube as well as along the long axis and short axis of thin tube were separately plotted,and a questionnaire survey was conducted.Results The learning curve of the mean time of puncturing along the long axis of the thick tube appeared an turning point at the fourth time,and then the curve became gradually stabilized,and the mean time of puncture was less than 19s.No turning point of the learning curve appeared after 10 times of practice of puncturing along the short axis of thick tube,along the long axis of thin tube and along the short axis of thin tube.The results of the questionnaire survey indicated that the majority of refresher doctors considered that using this model to practice puncturing manipulation could stimulate their learning interest to a large or greater extent,improve their confidence in independent operation,and further improve their understanding of the knowledge of ultrasound intervention.Conclusion After the theoretical training,observing the interventional puncture demonstration,and 4 times of puncturing practice,the refresher doctors can basically master the skill of ultrasound-guided puncturing along the long axis of the thick tube,but the skill of puncturing along the short axis of the thick tube,along the long axis of the thin tube and along the short axis of the thin tube cannot reach a stable level,it means that for them more puncturing practice opportunities are still needed.
