基于情景模拟教育在推广简明DA-CPR模式的运用效果评价

Evaluation on application effect of promoting concise DA-CPR model based on scenario simulation education

[目的]探讨以情景模拟教育为基础的简明调度员辅助心肺复苏指令(dispatcher-assisted CPR instruction,DA-CPR)模式对非医学普通居民心肺复苏知识及技能的影响。[方法]将符合入选要求的360例普通居民通过信封法随机分为A组、B组和C组,采用简明DA-CPR模式帮助A组识别模拟心搏骤停病人并指引实施心肺复苏,B组则采用常规DA-CPR模式,C组不作任何干预,收集并比较3组心肺复苏相关知识得分、从呼救至实施抢救的时间以及心肺复苏质量。[结果]干预后A组和B组的心肺复苏相关知识得分为(83.73±11.96)分和(82.79±11.34)分,明显高于C组的(64.87±12.73)分(P<0.05);3组呼救至实施心肺复苏的时间依次为A组(90.63±15.87)s、B组(106.54±21.18)s和C组(127.98±18.10)s,组间两两比较差异均具有统计学意义(P<0.05);在按压深度、频率和胸廓回弹的达标率方面,由高到低依次均为A组、B组、C组,差异具有统计学意义(P<0.05)。[结论]以情景模拟教育为基础的简明DA-CPR模式可有效提升普通居民的心肺复苏知识及操作能力,对于提升全民的急救初步处理能力具有积极的促进意义。

Objective： To probe into the eefect of concise Dispatcher - assisted CPR Instruction（DA - CPR） model on the knowledge and skills of cardiopulmonary resuscitation among non-medical residents based on situational simulation education. Methods： A total of 360 ordinary residents who met the requirements were randomly divid-ed into group A,group B and group C by envelope method. The patients in group A were diagnosed with simula-ted cardiac arrest and guided cardiopulmonary resuscitation with concise DA - CPR model. Patients in group B used conventional DA - CPR model. No intervention was made in group C. The scores of cardiopulmonary resus-citation related knowledge,the period from the call for help to implement the rescue,and the quality of cardiop-ulmonary resuscitation were collected and compared. Results： The scores of cardiopulmonary resuscitation relat-ed knowledge ingroup A andgroup B were （83. 73 ± 11. 96） points and （ 82 79 ± 11. 34） points, respectively,which were significantly higher than those ing ro upC （64. 87 ± 12 73） points（P 〈0. 05）. The period from the call for help to implement the rescue was（90. 63± 15. 87） seconds in groupA（106. 54±21 18） seconds in group B and（127. 98± 18. 10）seconds in groupC. The between group variances were statistically significant（P〈0. 05）. In the rate of reaching the standard in press depth, press frequency and thorax resilience,Group A〉Group B〉Group C;the difference was statistically significant（P 〈0. 05）. Conclusions ： The concise DA - CPR model based on situational simulation education could effectively improve the knowledge and operation ability of cardiopulmonaryresuscitation among ordinary residents , which was of great significance to promoting the preliminary handlingcapacity of first aid.
