Third-year students in the Dresden Medical School Programme undergo a 6 week course 'Basics of Drug Therapy' in a problem-based learning curriculum. As part of this course a practical seminar about antiarrhythmic drugs and ECG was set up. This study was conducted to evaluate the use of a simulator in this course.
A total of 234 students were randomly allocated to receive instructions with (Group S) or without (Group C [control]) the use of a simulator. After a lecture on antiarrhythmic drugs, arrhythmias were presented to Group S using an advanced life support (ALS) manikin. The students were asked to administer a drug or to defibrillate, and the outcome was shown on the monitor. The students in Group C were presented with ECG charts without a simulator. The course was evaluated by a questionnaire and multiple-choice questions (MCQ) about arrhythmias.
We received 222 questionnaires. The content-time ratio was rated almost perfect in both groups, but the students in Group S rated the course better suited to link theory and practice. Students in Group S considered the simulator helpful and a good tool for teaching, and the extra effort to be worthwhile. A significantly higher number of students in Group S preferred electric cardioversion as therapy for ventricular tachycardia.
An ALS manikin can be an effective tool in teaching clinical pharmacology.
德累斯顿医学院项目的三年级学生在基于问题的学习课程中接受为期6周的“药物治疗基础”课程。作为该课程的一部分，设立了一个关于抗心律失常药物和心电图的实践研讨会。本研究旨在评估模拟器在该课程中的应用。
总共234名学生被随机分配，一组（S组）使用模拟器接受指导，另一组（C组[对照组]）不使用模拟器接受指导。在关于抗心律失常药物的讲座之后，使用高级生命支持（ALS）人体模型向S组展示心律失常情况。要求学生给药或除颤，并在监视器上显示结果。C组学生观看没有模拟器的心电图图表。通过问卷调查和关于心律失常的多项选择题（MCQ）对该课程进行评估。
我们收到了222份问卷。两组对内容-时间比的评价都几乎是完美的，但S组学生认为该课程更适合将理论与实践联系起来。S组学生认为模拟器很有帮助，是一种很好的教学工具，额外的努力是值得的。S组中明显更多的学生倾向于选择电复律作为室性心动过速的治疗方法。
ALS人体模型可以成为临床药理学教学的有效工具。
