In recent years, ultrasound (US) has become more incorporated into anesthesia and intensive care medicine. The German Anesthesia Society established a modular curriculum to teach US skills. Until now, the efficacy of this modular curriculum has not been validated.
The main objective of this study was to determine whether there is an increase of knowledge and of psychomotor skills for the trainees in this curriculum.
After ethical committee approval, 41 anesthesia physicians were enrolled. To determine the increase of knowledge and of practical skills theoretical and practical tests performed were evaluated before and after two different US courses.
Comparing before and after course tests, the participants showed significant improvement in theoretical multiple choice tests (p = 0.008). Regarding psychomotor skills following course 1, the trainees improved significantly in the time needed to perform the two practical tests (p = 0.03), but not in the performance of the test. Better needle visualization during simulated US-guided vessel puncture (p = 0.52) and better identification of the anatomical structures in the axillary region (p = 0.56) could not be achieved.
This study shows that although this US course curriculum has positively enhanced the trainees' theoretical knowledge of US practice, it does not enhance the practical application of that theoretical knowledge. To improve this curriculum, a supervised clinically practical training should follow the course.
近年来,超声(US)已更多地应用于麻醉学和重症监护医学。德国麻醉学会制定了一个模块化课程来教授 US 技能。到目前为止,该模块化课程的效果尚未得到验证。
本研究的主要目的是确定该课程是否能提高学员的知识和运动技能。
在获得伦理委员会批准后,纳入 41 名麻醉医师。为了确定知识和实践技能的提高,在两次不同的 US 课程前后,对理论和实践测试进行了评估。
与课程前后的测试相比,参与者在理论多选题测试中表现出显著的改善(p=0.008)。在课程 1 后的运动技能方面,学员在完成两项实践测试所需的时间上有显著提高(p=0.03),但在测试的表现上没有提高。在模拟 US 引导血管穿刺时,更好地观察到了针的可视化(p=0.52),在腋区更好地识别了解剖结构(p=0.56),但没有得到改善。
本研究表明,尽管该 US 课程能提高学员对 US 实践的理论知识,但不能提高该理论知识的实际应用。为了改进该课程,应在课程后进行监督的临床实践培训。
