Abstract

Background: There are limited opportunities to practice surgical skills and techniques in residency. Therefore, it is important to explore strategies which optimize surgical simulation experiences to enhance learning outcomes and skill retention.

Methods: Novice medical students (n = 29) were recruited to participate in a Fundamentals of Laparoscopic Surgery (FLS) peg transfer task training. Participants were randomly assigned to a control group, practicing the peg transfer task independently, or an experimental group, practicing with time pressure. Participant skill assessments were completed before the training, after the training, and 8-weeks after the training. Subjective and objective stress measurements were taken in the form of self-report surveys and heart rate variability data, respectively.

Results: For all the skill assessment measurements, there was no difference between groups in performance on the FLS task. Both groups showed improvement in performance after the training compared to before. The experimental group reported higher stress during and after the training period compared to the control group; however, there was no difference between groups on heart rate variability metrics.

Conclusion: Time pressure while practicing an FLS task did not significantly impact learning acquisition or retention. However, the experimental group reported higher levels of stress. This preliminary study suggests time pressure does not confer an enhanced surgical skill learning experience for novices.

时间压力对新手外科技能保持的影响:随机对照试验
背景:在住院医师培训中练习外科技能和技巧的机会有限。因此,探索优化手术模拟体验的策略以提高学习效果和技能保持率非常重要:方法:招募新手医学生(n = 29)参加腹腔镜手术基础(FLS)挂钩转移任务培训。参与者被随机分配到对照组(独立练习转移挂钩任务)或实验组(有时间压力的练习)。学员在训练前、训练后和训练 8 周后分别完成了技能评估。主观和客观压力测量分别以自我报告调查和心率变异数据的形式进行:结果:在所有技能评估测量中,各组在 FLS 任务上的表现没有差异。两组在训练后的表现都比训练前有所提高。与对照组相比,实验组在训练期间和训练结束后的压力更大;但在心率变异性指标上,组间没有差异:结论:练习 FLS 任务时的时间压力对学习的掌握和保持没有显著影响。结论:练习 FLS 任务时的时间压力对学习的掌握和保持没有明显影响,但实验组的压力水平更高。这项初步研究表明,时间压力并不会增强新手的外科技能学习体验。

期刊介绍: Surgical Innovation (SRI) is a peer-reviewed bi-monthly journal focusing on minimally invasive surgical techniques, new instruments such as laparoscopes and endoscopes, and new technologies. SRI prepares surgeons to think and work in "the operating room of the future" through learning new techniques, understanding and adapting to new technologies, maintaining surgical competencies, and applying surgical outcomes data to their practices. This journal is a member of the Committee on Publication Ethics (COPE).
