基于模拟人研究不同医学背景对胸外按压质量的影响

Effects of Different Hospital Staff on Quality of Chest Compressions:A Manikin Study

目的:利用模拟人研究不同医学背景对胸外按压质量的影响、评估疲劳程度与胸外按压质量的相关性。方法:190名医院内不同岗位的志愿者被招募并参加本次队列研究。研究共分为4组:(1)非医学背景组(NM组);(2)辅助科室组(CT组);(3)普通医护组(GM组);(4)危重症组(CCM组)。所有志愿者均需要在模拟人身上进行持续2分钟的单纯胸外按压,同步地我们分别对其胸外按压质量、施救者疲劳评分(PRE)等进行了评估。结果:GM组和CCM组的按压深度显著优于其他两组,更重要的是CCM组的胸廓充分回弹的比例和胸外按压正确率都要明显优于其他3组,包括GM组。结论:医院不同岗位志愿者的胸外按压质量存在显著差异,医疗专业的志愿者较非医疗专业的按压质量高。

Objective:To investigate the effect of different hospital staff on quality of chest compressions,as with fatigue. Methods:Total 190 volunteers were recruited. Non-medical staff were assigned into NM group,pharmacists and staff in clinical laboratory into CT group,medical staff in charge of general and milder cases into GM group and those in charge of critical and emergency cases into CCM group respectively. Results:The depth of CCs achieved in the GM group and CCM group were significantly greater when compared with the other two groups. The numbers of complete chest recoil and appropriate CCs achieved in CCM group were markedly greater than those in the other threegroups.Conclusion:The quality of CCs performed by the clinical medical staff was better than non-clinical-medical-staff due to frequent training and more experiences of CPR.
