Chest compressions and early defibrillation are crucial in cardiopulmonary resuscitation (CPR). The Guidelines 2005 brought major changes to the basic life support and automated external defibrillator (BLS-AED) algorithm. We compared the European Resuscitation Council's Guidelines 2000 (group '00) and 2005 (group '05) on hands-off-time (HOT) and time to first shock (TTFS) in an experimental model.
In a randomised, cross-over design, volunteers were assessed in performing BLS-AED over a period of 5min on a manikin in a simulated ventricular fibrillation cardiac arrest situation. Ten minutes of standardised teaching and 10min of training including corrective feedback were allocated for each of the guidelines before evaluation. HOT was chosen as the primary and TTFS as the secondary outcome parameter.
Forty participants were enrolled; one participant dropped out after group allocation. During the 5-min evaluation period of adult BLS-AED, HOT was significantly (p<0.001) longer in group '00 [273+/-3s (mean+/-standard error)] than in group '05 (188+/-3s). The TTFS was significantly (p<0.001) longer in group '00 (91+/-3s) than in group '05 (71+/-3s).
In this manikin setting, HOT and TTFS improved with BLS-AED performed according to Guidelines 2005.
胸外按压和早期除颤在心肺复苏（CPR）中至关重要。《2005年指南》给基本生命支持和自动体外除颤器（BLS - AED）算法带来了重大改变。我们在一个实验模型中比较了欧洲复苏委员会的《2000年指南》（“00组”）和《2005年指南》（“05组”）在无按压时间（HOT）和首次除颤时间（TTFS）方面的差异。
采用随机交叉设计，让志愿者在模拟心室颤动心脏骤停情况下，在人体模型上进行5分钟的BLS - AED操作评估。在评估前，针对每个指南分配10分钟的标准化教学和10分钟包括纠正反馈的训练。选择HOT作为主要结局参数，TTFS作为次要结局参数。
招募了40名参与者；1名参与者在分组后退出。在成人BLS - AED的5分钟评估期内，“00组”的HOT[273±3秒（均值±标准误）]显著长于“05组”（188±3秒）（p<0.001）。“00组”的TTFS（91±3秒）显著长于“05组”（71±3秒）（p<0.001）。
在这种人体模型设置中，按照《2005年指南》进行BLS - AED操作时，HOT和TTFS得到了改善。
