目的 探讨基于急救流程的视频分析结合PBL的教学模式在急诊本科护生创伤模拟教学中的应用效果.方法 将2016年9-12月来武汉大学中南医院急救中心实习的本科护生120名作为研究对象,其中单月为对照组,双月为观察组每组各60名.2组护生在第一周集中讲解创伤处理理论知识以及急救流程、观看创伤处理的教学视频;第二、三周采取跟班轮转一对一临床带教的方法,第四周对照组采取常规抽取案例模拟演练,观察组由授课老师截取抢救视频运用PBL的教学模式指导其3~5人为一组讨论并运用急救流程分析抢救视频,再模拟演练的方式,最后比较2组护生在理论成绩、模拟案例考核成绩及其对教学效果的评价.结果 教学结束后观察组的理论成绩、操作成绩、对课程评价分别为(89.17 ± 5.55)、(88.62 ± 5.64)、(91.55 ± 4.32)分,对照组分别为(82.72 ± 4.92)、(74.25 ± 7.68)、(83.64 ± 3.54)分,2组比较差异有统计学意义(t=6.742、11.681、10.973,P<0.01).结论 基于急救流程的视频分析结合PBL教学模式能提高本科护生的创伤急救能力,激发护生的自主学习兴趣,有利于提高护生的急救应变能力和解决问题的能力.

Objective To discuss the video analysis basing on emergency process,and combined with the application effect on PBL(Problem based learning)teaching model in trauma simulation teaching for emergency undergraduate intern students. Methods There were 120 undergraduate intern students, coming to the hospital from January to December in 2016,been selected as subjects.The single month was the control group,and the bimonthly was observation group.Each group contained of 60 members.In the first week, two groups focused on the theoretical knowledge of wound treatment, emergency treatment process and watched the trauma disposing video. In the second and third weeks, followed the rotation of one to one clinical teaching methods. In the fourth week, the control group took regular simulation exercises. Teachers might intercept a case of rescuer video and use PBL teaching mode to guide the observation group. Students would discuss and use the first aid process analysis rescue video in 3-5 persons a group. And then compared with two groups in the theoretical score, simulation exercises performance and the evaluation of teaching results. Results After the teaching program,the theoretical score of observation group was 89.17±5.55,and the control group was 82.72±4.92(t=6.742,P<0.01).The simulation exercises score of observation group was 88.62±5.64,and the control group was 74.25±7.68(t=11.681, P<0.01). The evaluation score of teaching results of observation group was 91.55±4.32, and the control group was 83.64 ± 3.54 (t=10.973, P<0.01). The difference between two groups was statistically significant. Conclusion The use of the first aid process of video analysis combined with PBL teaching model can improve the trauma of the nursing students first aid ability,stimulate students'interest in self-study,and improve the ability of first aid and solving problems
