心肺复苏术（CPR）的实施指南最近已经修订，现在提倡在心搏停止和无脉性电活动期间对患者进行连续3分钟的胸外按压。本研究的目的是确定在3分钟的胸外按压过程中是否会发生救援人员疲劳，如果是，对按压速度和质量的影响。研究了40名能够进行基本生命支持（BLS）的受试者。他们在Laerdal Skillmeter（TM）Resusci-Anne（R）人体模型上进行连续胸外按压，连续两次，每次3分钟，间隔30秒。在整个研究期间，尝试按压的总次数保持在约100 min（-1）。然而，在复苏过程中，满意的胸外按压次数逐渐减少（P < 0.001），如下：第一分钟，82分钟（-1）;第二分钟，68分钟（-1）;第三分钟，52分钟（-1）;第四分钟，70分钟（-1）;第五分钟，44分钟（-1）;第六分钟，27分钟（-1）。我们观察到令人满意的按压次数与施救者的身高和体重之间存在显著相关性。与男性相比，女性受试者获得的满意按压明显较少（P = 0.03）。7名受试者（5名女性，2名男性）由于疲劳而无法完成第二个3分钟阶段。我们的结论是，救援人员疲劳的胸外按压的质量产生不利影响时，不中断超过3分钟的时间内，这种影响可能是更大的女性，由于他们的身材较小。应考虑在1分钟间隔后旋转进行胸外按压的救援人员。(C)2002爱思唯尔科学爱尔兰有限公司保留所有权利。
Guidelines for the performance of cardiopulmonary resuscitation (CPR) have been revised recently and now advocate that chest compressions are performed without interruption for 3 min in patients during asystole and pulseless electrical activity. The aim of the present study was to determine if rescuer fatigue occurs during 3 min of chest compressions and if so, the effects on the rate and quality of compressions. Forty subjects competent in basic life support (BLS) were studied. They performed continuous chest compressions on a Laerdal Skillmeter(TM) Resusci-Anne(R) manikin for two consecutive periods of 3 min separated by 30 s. The total number of compressions attempted was well maintained at approximately 100 min(-1) throughout the period of study. However, the number of satisfactory chest compressions performed decreased progressively during resuscitation (P < 0.001) as follows: first min, 82 min(-1); second, 68 min(-1); third, 52 min(-1); fourth, 70 min(-1); fifth, 44 min(-1); sixth, 27 min(-1). We observed significant correlations between the number of satisfactory compressions performed and both height and weight of the rescuer. Female subjects achieved significantly fewer satisfactory compressions compared with males (P = 0.03). Seven subjects (five female, two male) were unable to complete the second 3-min period because of exhaustion. We conclude that rescuer fatigue adversely affects the quality of chest compressions when performed without interruption over a 3-min period and that this effect may be greater in females due to their smaller stature. Consideration should be given to rotating the rescuer performing chest compressions after I min intervals. (C) 2002 Elsevier Science Ireland Ltd. All rights reserved.
