The aims of this study were to develop a novel three-finger chest compression technique (pinch technique; PT) and an assistive device chest compression technique (plate-assisted technique; PAT) and compare these techniques with conventional techniques.
Prospective, crossover manikin study.
Pediatric emergency department at a tertiary care academic center.
Fifty medical doctors and medical students.
Using a manikin, fifty participants performed five different chest compression techniques-two 2-finger techniques (TFT1 and TFT2), two PTs (PT1 and PT2), and the PAT-for 2 minutes with 2 minutes of rest in a randomized sequence.
The compression depth (CD), compression rate, recoil, and finger position were recorded. At the study conclusion, each participant completed a 5-point Likert scale-based questionnaire on fatigue, satisfaction and difficulty of performing each technique. The mean CDs were 32.9 mm (TFT1), 30.3 mm (TFT2), 37.3 mm (PT1), 35.0 mm (PT2) and 40.1 mm (PAT) (p<0.001). TFT2 achieved the highest frequency of complete chest recoil, followed by PT1 and TFT1 (88.9%, 86.9%, and 81.4%, respectively, p = 0.003). The highest percentage of correct finger position was achieved by the PAT, followed by the PT1 and PT2 (93.4%, 83.1%, and 80.1%, respectively, p = 0.016). PAT use resulted in higher participant satisfaction, less fatigue, and less difficulty than the other four techniques.
Our new chest compression methods using three fingers and assistive plates showed better CD results than the conventional 2-finger technique.
本研究旨在开发一种新的三指胸外按压技术(捏合技术;PT)和一种辅助装置胸外按压技术(板辅助技术;PAT),并将这些技术与传统技术进行比较。
前瞻性、交叉式模拟人研究。
三级护理学术中心的儿科急诊室。
五十名医生和医学生。
使用模拟人,五十名参与者以随机顺序用五种不同的胸外按压技术进行 2 分钟的按压-两种 2 指技术(TFT1 和 TFT2)、两种 PT(PT1 和 PT2)和 PAT-在 2 分钟的休息后。
记录按压深度(CD)、按压频率、回弹和手指位置。在研究结束时,每位参与者完成了一份基于 5 点李克特量表的问卷,评估对每种技术的疲劳感、满意度和实施难度。平均 CD 分别为 32.9mm(TFT1)、30.3mm(TFT2)、37.3mm(PT1)、35.0mm(PT2)和 40.1mm(PAT)(p<0.001)。TFT2 实现了完全的胸外回弹的最高频率,其次是 PT1 和 TFT1(分别为 88.9%、86.9%和 81.4%,p=0.003)。正确手指位置的最高百分比是 PAT 实现的,其次是 PT1 和 PT2(分别为 93.4%、83.1%和 80.1%,p=0.016)。与其他四种技术相比,PAT 的使用可带来更高的参与者满意度、更低的疲劳感和更小的难度。
我们新的使用三指和辅助板的胸外按压方法显示出比传统的 2 指技术更好的 CD 结果。
