Simulation studies in adults and pediatrics demonstrate improvement in chest compression (CCs) quality as providers rotate every two minutes. There is paucity of studies in neonates on this matter. This study hypothesized that frequent rotation while performing CCs improves provider performance and decreases fatigue.
Prospective randomized, observational crossover study where 51 providers performed 3:1 compression-ventilation CPR as a pair on a term manikin. Participants performed CCs as part of 3 simulation models, rotating every 3, 5 and 10 minutes. Data on various CC metrics were collected. Participant vitals were recorded at multiple points during the simulation and participants reported their level of fatigue at completion of simulation.
No statistically significant difference was seen in any of the compression metrics. However, differences in the providers' fatigue scores were statistically significant.
CC performance metrics did not differ significantly, however, providers' vital signs and self-reported fatigue scores significantly increased with longer CC durations.
成人和儿科的模拟研究表明，每两分钟轮换一次可提高胸外按压（CCs）的质量。关于这一点，新生儿的研究很少。本研究假设，在进行 CCs 时频繁轮换可以提高提供者的表现并降低疲劳感。
这是一项前瞻性随机对照交叉研究，51 名提供者成对地在足月模型上进行 3:1 按压通气心肺复苏术。参与者作为 3 个模拟模型的一部分进行 CCs 操作，每 3 分钟、5 分钟和 10 分钟轮换一次。收集了各种 CC 指标的数据。在模拟过程中的多个时间点记录参与者的生命体征，并在模拟结束时报告他们的疲劳程度。
在任何 CC 指标上均未观察到统计学上的显著差异。然而，提供者的疲劳评分差异具有统计学意义。
CC 表现指标没有显著差异，但是，随着 CC 持续时间的延长，提供者的生命体征和自我报告的疲劳评分显著增加。
