摘要
目的探讨医学生应用模拟人进行胸腔穿刺模拟训练的学习曲线。方法48名医学生进行胸腔穿刺模拟训练，每人在模拟人身上进行5次模拟训练，对每次操作的操作失误（performance errors，PE）、操作时间（procedure time，PT）及操作者信心（participant＇s confidence，PC）三个方面进行评价，各变量分别绘制学习曲线。0．5年后再次评估其远期效果。结果学生在5次操作中，PE、PC和PT随操作次数的增加逐渐改善，到第4次操作时达到平台期。0．5年后的考核结果与培训时第5次操作结果相似（P〉0．05）。结论应用模拟人进行胸腔穿刺模拟训练可以显著提高学生的临床操作能力，4次操作练习即可以达到满意效果。
Objective The purpose of this study is to document the learning curve of simulation based thoracentesis training and to evaluate its long term outcome. Methods Forty-eight medical students were enrolled in this study. Each participant performed 5 supervised but unmentored thoracentesis on the simulator. Participant＇s performance was assessed by performance errors （PE） , procedure time （PT） and participant＇ s confidence （PC） by the supervisors for every operator on each test trial. Learning curves for each variable were generated. Long term outcomes of the training were measured by the re-test on half year later. Results An obvious improvement was noted in PE, PT and PC when comparing the subjects 1 st and 4th test trial （ P 〈 0. 01 ）. A plateau for PE, PT and PC in the learning curve occurred in 4th test trial. The results of re-test on half year later were similar with that in the test trial 5 （ P 〉 0. 05 ）. Conclusions This study demonstrated simulation based thoracentesis training can significantly improve the individual＇ s skill. The full effect of learning from the modular can be achieved by four times of practices.
