摘要
目的探讨使用音乐节拍器引导不同胸外心脏按压频率对各项质量指标的影响,为高品质胸外心脏按压培训提供依据。方法采用随机数字表法将132名新护士分为自由按压组(n=44)、100次/min组(n=44)及120次/min组(n=44),经培训后分别实行2min自由胸外心脏按压、节拍器引导100次/min和120次/min频率胸外心脏按压。使用单因素方差分析及非参数检验了解三组间各项按压指标是否存在差异。结果三组间按压频率、总按压次数、按压深度、足够深度次数、操作正确次数及疲劳时间比较,差异有统计学意义(P<0.05,P<0.01)。结论使用音乐节拍器引导胸外心脏按压,能保证稳定的按压频率及节律。节拍器引导100次/min频率的胸外按压比120次/min及自由按压更能保证按压深度、按压正确率,并延长按压者疲劳的时间。
Objective To explore the impact of music metronome guidance chest compressions at different rates on quality indicators,so as to provide basis for high-quality chest compression training.Methods A total of 132 new nurses were divided into a free compression group （n=44）,a 100/min group （n=44） and a 120/min group（n=44） randomly.After training,in 2 minutes,the free compression group performed free chest compression,the second group performed metronome guidance chest compression at 100 beats/min,and the third group at 120 beats/min.One-way analysis of variance and non-parametric test were used to analyze whether there were differences among the three groups.Results There were significant differences in compression rate,the total counts of compression,depth of compression,counts of compression without mistakes,counts of compression with enough depth,and fatigue time among the three groups （P〈0.05,P〈0.01）.Conclusion Music metronomes can be used to set stable rate and rhythm in chest compression.Metronome guiding chest compression at 100/min can ensure deeper compression,more compression without mistake and longer fatigue time compared to 120/min and free compression.
