Effective cardiopulmonary resuscitation (CPR) is critical to ensure optimal outcomes from cardiac arrest, yet trained health care providers consistently struggle to provide guideline-compliant CPR. Rescuer fatigue can impact chest compression (CC) quality during a cardiac arrest event, although it is unknown if visual feedback or just-in-time training influences change of CC quality over time. In this study, we attempt to describe the changes in CC quality over a 12-minute simulated resuscitation and examine the influence of just-in-time training and visual feedback on CC quality over time.
We conducted secondary analysis of data collected from the CPRCARES study, a multicenter randomized trial in which CPR-certified health care providers from 10 different pediatric tertiary care centers were randomized to receive visual feedback, just-in-time CPR training, or no intervention. They participated in a simulated cardiac arrest scenario with 2 team members providing CCs. We compared the quality of CCs delivered (depth and rate) at the beginning (0-4 minutes), middle (4-8 minutes), and end (8-12 minutes) of the resuscitation.
There was no significant change in depth over the 3 time intervals in any of the arms. There was a significant increase in rate (128 to 133 CC/min) in the no intervention arm over the scenario duration (P < 0.05).
There was no significant drop in CC depth over a 12-minute cardiac arrest scenario with 2 team members providing compressions.
有效的心肺复苏(CPR)对于确保心脏骤停患者获得最佳预后至关重要,但经过培训的医护人员在提供符合指南的 CPR 时始终存在困难。在心脏骤停事件中,救援者疲劳可能会影响胸外按压(CC)的质量,尽管尚不清楚视觉反馈或即时培训是否会随着时间的推移影响 CC 质量的变化。在这项研究中,我们试图描述在 12 分钟模拟复苏过程中 CC 质量的变化,并研究即时培训和视觉反馈对 CC 质量随时间变化的影响。
我们对 CPRCARES 研究的数据进行了二次分析,该研究是一项多中心随机试验,来自 10 家不同儿科三级护理中心的 CPR 认证医护人员被随机分配接受视觉反馈、即时 CPR 培训或不干预。他们参与了一个模拟心脏骤停场景,由 2 名团队成员提供 CC。我们比较了复苏开始(0-4 分钟)、中期(4-8 分钟)和结束(8-12 分钟)时 CC 质量(深度和频率)。
在任何干预组中,深度在 3 个时间间隔内均无显著变化。在无干预组中,随着场景持续时间的延长,频率显著增加(128 次/分至 133 次/分,P < 0.05)。
在由 2 名团队成员提供 CC 的 12 分钟心脏骤停场景中,CC 深度没有明显下降。
