Sudden cardiac arrest remains a leading global cause of death. High-quality chest compressions during cardiopulmonary resuscitation (CPR) are crucial for patient outcomes. Basic life support (BLS) training must be adequately incorporated into undergraduate training. During the pandemic-regulated restrictions, our institute started the online CPR training course for medical undergraduates so that some training could be imparted to them if they needed to staff the clinical areas. This study compared online with traditional mannequin-based CPR training regarding skill acquisition and knowledge retention.
This randomized cross-sectional study involved 108 medical undergraduates divided into two groups to receive online-based training (Group 1) and mannequin-based training (Group 2). Compression depth and rate were objectively measured using an AmbuMan CPR training mannequin. Knowledge assessment was conducted using relevant clinical vignettes, and participant performance was assessed using a skill-based checklist.
Both groups had comparable baseline knowledge. Group 2 exhibited significantly higher post intervention knowledge assessment and skill-based checklist scores. Mean compression depth [36.28 (13.84) vs 51.6 (8.7), < 0.001] and median rate [110 (87.5 to 129.50) vs 123.0 (111.0 to 133.0), = 0.012] were better in mannequin trained participants. Group 2 participants demonstrated superior skills across all checklist items, with notable differences in pre compression and compression steps. Scene safety checks (62%), compression rate (44%), and compression depth (48%) showed the most significant improvements, whereas steps involving Automated External Defibrillator (AED) usage had minimal enhancements.
The findings of this study are significant, demonstrating that hands-on mannequin-based training is significantly more effective than online training in teaching BLS skills to novice medical students, particularly in achieving correct chest compression depth and rate. The study's findings indicate that hands-on training is indispensable for effective skill acquisition despite the widespread adoption of online teaching.
心脏骤停仍然是全球主要的死亡原因。心肺复苏（CPR）期间高质量的胸外按压对患者的预后至关重要。基础生命支持（BLS）培训必须充分纳入本科培训。在疫情管控限制期间，我们学院为医学本科生开设了在线CPR培训课程，以便在他们需要到临床区域工作时能传授一些培训内容。本研究比较了在线CPR培训与传统基于人体模型的CPR培训在技能获取和知识保留方面的差异。
这项随机横断面研究涉及108名医学本科生，分为两组，分别接受在线培训（第1组）和基于人体模型的培训（第2组）。使用AmbuMan CPR培训人体模型客观测量按压深度和速率。使用相关临床案例进行知识评估，并使用基于技能的检查表评估参与者的表现。
两组的基线知识水平相当。第2组在干预后的知识评估和基于技能的检查表得分显著更高。在接受人体模型培训的参与者中，平均按压深度[36.28（13.84）对51.6（8.7），<0.001]和中位数速率[110（87.5至129.50）对123.0（111.0至133.0），=0.012]更好。第2组参与者在所有检查表项目上都表现出更优的技能，在按压前和按压步骤上有显著差异。现场安全检查（62%）、按压速率（44%）和按压深度（48%）显示出最显著的改善，而涉及自动体外除颤器（AED）使用的步骤改善最小。
本研究结果意义重大，表明对于向新手医学生教授BLS技能，尤其是在实现正确的胸外按压深度和速率方面，基于人体模型的实践培训比在线培训显著更有效。研究结果表明，尽管在线教学广泛应用，但实践培训对于有效获取技能是不可或缺的。
