血气酸碱失衡分析软件在临床医学检验专业中的教学应用

目的应用血气酸碱失衡分析软件进行临床教学。 方法使用血气酸碱失衡分析软件，以临床生化检验教科书中的血气酸碱失衡检查为教学内容，依据《全国临床检验操作流程》的判断公式对临床的血气结果进行分析，应用于医学检验专业学生的教学实验。所有教学数据均来源于广州医科大学附属第二医院，共220例，男122例，女98例。对纳入数据进行示教，血气分析，其中正常65例，单纯型90例，混合型41例，三重型24例。 结果通过临床实测220例患者的数据结果，将手工判断与酸碱失衡分析软件的结果进行比较，通过Kappa检验评价两者的一致性，Kappa值为0.935，P＜0.001，两者结果一致性好。血气酸碱失衡辅助分析软件也能缩短血气判断的时间。同时，在教学应用中，进一步对软件进行了完善，增加了课后练习、参考资料、教学素材、教师信箱、医学检验最新动态、交流园地和公告栏等模块。 结论软件血气判断正确率高，使用方便，灵活和快速，让教学形式多样化，利于学生随时自主学习，同时也扩大学生知识面和增进血气专业知识掌握的深度，能激发学生学习兴趣。

Teaching application of blood gas and acid-base imbalance analysis software in clinical medical laboratory specialty Huang Haiying,Chen Bo,Zhou Qiang,Ji Tianxing,Lin Zhen,Chen Jingnan. The Second Affiliated Hospital of Guangzhou Medical University,Guangzhou Guangdong 510260, China

ObjectApplicating of the blood gas and acid-base imbalance analysis CAI software in clinical teaching. MethodsThe blood gas and acid-base imbalance analysis software was used to analyze the clinical blood gas results according to the judgment formula of the national clinical examination operation process, which is applied to the teaching experiment of medical laboratory students,and the unbalance of blood gas acid base in clinical biochemistry test textbook was used as teaching content. All teaching data were obtained from the Second Affiliated Hospital of Guangzhou Medical University, including 220 cases(122 males and 98 females).The inclusion requirement was that the blood gas data and electrolyte results of inpatients should be complete, and incomplete data should not be adopted. The included data were illustrated and analyzed by blood gas analysis, including 65 normal cases, 90 simple cases, 41 mixed cases and 24 triple severe cases. ResultThe results of manual judgment and acid-base imbalance analysis software were compared based on the clinical data of 220 patients. The consistency between software judgment and manual judgment was evaluated by Kappa test, and the kappa value was 0.935, P＜0.001. At the same time, it also greatly reduced the time of blood gas acid-base imbalance analysis. In the specific application process, the software was further improved, some modules such as exercises, reference materials, teaching materials, teachers' mailbox, latest news of medical laboratory science, forum and bulletin board were added. ConclusionThe CAI software had high accuracy of blood gas judgment, and is convenient, flexible and fast, and allows diversified teaching methods, which helps students to study independently at any time. Furthermore, it also expands students' scope of knowledge, deepens their expertise, and motivates their interests in learning.
