Abstract

Introduction: Reducing the compression rotation interval from 2 to 1 minute is expected to improve cardiopulmonary resuscitation (CPR) quality. This meta-analysis aimed to assess the effect of altering the compression rotation interval on key CPR quality parameters, including compression depth, rate, and rescuer fatigue.

Methods: We systematically searched MEDLINE, EMBASE, Scopus, Google Scholar, Web of Science, and the Cochrane Controlled Register of Trials from their inception to May 15, 2025. We searched for randomized controlled trials, simulation studies, and crossover studies that compared 1-min and 2-min compression rotation times. The assessed outcomes included compression depth, rate, correctness, and rescuer fatigue, which were reported as the standard mean difference (SMD) with a 95% confidence interval (95% CI).

Results: One randomized controlled trial and seven randomized crossover studies, involving 668 rescuers in total, using manikins, were included. The 1-min rotation group exhibited significantly greater compression depth, with an increase of 2.06 mm (SMD = 2.06, 95% CI: 0.44-3.68, p < 0.001). This group demonstrated lower levels of fatigue, as indicated by a significant reduction on the visual analog scale for fatigue (SMD = -1.27, 95% CI: -2.24 to -0.30, p < 0.001). However, there were no significant differences in the compression rate or percentage of compressions that achieved adequate depth.

Conclusion: It seems that altering the chest compression rotation interval from 2 min to 1 min improves the compression depth and reduces rescuer fatigue. However, parameters, such as the compression rate and compression adequacy, remained unchanged. Notably, all the studies were conducted on manikins, thus necessitating further research to assess the applicability of these changes in real-world clinical settings.

压缩旋转间隔对心肺复苏质量的影响:系统回顾和荟萃分析。
将按压旋转间隔从2分钟减少到1分钟有望提高心肺复苏(CPR)质量。本荟萃分析旨在评估改变按压旋转间隔对心肺复苏术关键质量参数的影响,包括按压深度、按压速率和施救者疲劳。方法:我们系统地检索了MEDLINE、EMBASE、Scopus、谷歌Scholar、Web of Science和Cochrane Controlled Register of Trials,从它们成立到2025年5月15日。我们检索了比较1分钟和2分钟压缩旋转时间的随机对照试验、模拟研究和交叉研究。评估的结果包括压缩深度、速率、正确性和救援人员疲劳,这些结果以95%置信区间(95% CI)的标准平均差(SMD)报告。结果:纳入1项随机对照试验和7项随机交叉研究,共涉及668名使用人体模型的救援人员。旋转1 min组压迫深度增加2.06 mm (SMD = 2.06, 95% CI: 0.44-3.68, p < 0.001)。这一组表现出较低的疲劳水平,正如疲劳的视觉模拟量表显着降低所表明的那样(SMD = -1.27, 95% CI: -2.24至-0.30,p < 0.001)。然而,在压缩率或达到足够深度的压缩百分比方面没有显著差异。结论:将胸按压旋转间隔由2 min改为1 min,可提高按压深度,减轻抢救者疲劳。但是,压缩率和压缩充分性等参数保持不变。值得注意的是,所有的研究都是在人体模型上进行的,因此需要进一步的研究来评估这些变化在现实世界临床环境中的适用性。
