研究目的：我们进行了一项前瞻性、随机、对照试验，以验证一个假设，即34分钟的成人心肺复苏术视频自学（VSI）培训计划可以产生与目前的社区标准——美国心脏协会心脏保护课程相当或更好的心肺复苏术效果。方法：新生随机分为VSI组和Heartsaver CPR组。训练后2到6个月，我们测试了受试者，以确定他们在模拟心脏骤停环境下进行心肺复苏术的能力。盲法观察者使用明确的标准来评估我们的主要结局，CPR执行技能。此外，我们评估了次要结果，包括个人技能的顺序表现、通气和胸部按压特征，以及心肺复苏相关知识和态度的书面测试。结果：VSI学员整体表现优于传统学员。47名传统受训者中有20名（43%）被认为不能胜任心肺复苏术，而42名VSI受训者中只有8名（19%；绝对差值为24%；95%置信区间为5%至42%）。结论：在一组医学新生中，我们发现半小时的VSI比传统的受训者有更好的心肺复苏术的整体表现。如果经过进一步的研究验证，VSI可能为医护人员，甚至是普通人群提供一种简单、快速、廉价的传统CPR指导的替代方法。
Study objective: We conducted a prospective, randomized, controlled trial to test the hypothesis that a 34-minute video self-instruction (VSI) training program for adult CPR would yield comparable or better CPR performance than the current community standard, the American Heart Association Heartsaver course.Methods: Incoming freshman medical students were randomly assigned to VSI or the Heartsaver CPR course. Two to 6 months after training, we tested subjects to determine their ability to perform CPR in a simulated cardiac arrest setting. Blinded observers used explicit criteria to assess our primary outcome, CPR performance skill. In addition, we assessed secondary outcomes including sequential performance of individual skills, ventilation and chest compression characteristics, and written tests of CPR-related knowledge and attitudes.Results: VSI trainees displayed superior overall performance compared with traditional trainees. Twenty of 47 traditional trainees (43%) were judged not competent in their performance of CPR, compared with only 8 of 42 VSI trainees (19%; absolute difference, 24%; 95% confidence interval, 5% to 42%).Conclusion: In a group of incoming freshman medical students, we found that a half-hour of VSI resulted in superior overall CPR performance compared with that in traditional trainees. If validated by further research, VSI may provide a simple, quick, and inexpensive alternative to traditional CPR instruction for health care workers and, perhaps, the general population.
