PBL结合情景教学在激光辅助超声桡动脉穿刺教学中的应用

Implementing PBL in Laser-Assisted Ultrasound-guided Radial Artery Puncture

目的探究以问题为导向的学习法(PBL)与情景教学法相结合的创新模式在激光辅助超声桡动脉穿刺技术教学中的应用效果,以提升学生的实践能力和临床技能。方法选取2022-2023年在吉林大学第一医院麻醉科进行住院医师培训的40名学生,随机信封法分为传统教学组(对照组)18名和PBL结合情景教学组(结合组)22名。对照组接受传统教学方式,结合组以问题为基础,结合真实临床情景进行教学。通过基础理论知识和直接观察操作技能(DOPS)评估,对两组学生教学效果进行比较分析,并比较两组学生的临床能力。结果结合组在临床操作技能考核中,对物品准备、无菌操作及穿刺评分等技能操作的DOPS评估均明显优于对照组(P<0.05);临床能力考核Mini-CEX评估,结合组在医疗面谈能力、人文关怀、临床诊断、整体临床能力方面均明显优于对照组(P<0.05);教学效果的调查问卷,结合组在临床思维能力和操作能力方面认可人数明显多于对照组(P<0.05)。结论PBL结合情景教学模式明显优于传统教学,学生的临床能力和技能操作更佳,教学效果显著。

Objective This study examines the effectiveness of integrating problem-based learning(PBL)and situational teaching in laser-assisted ultrasound-guided radial artery puncture training to enhance students′practical and clinical skills.Methods Forty anesthesiology residents from the First Hospital of Jilin University(2022-2023)were randomly assigned to traditional teaching(control group)(n=18)or PBL with situational teaching(combined group)(n=22).The latter group engaged in problem-based scenarios.Assessments included the control knowledge and direct observation of procedural skills(DOPS).Results The PBL combined group outperformed the control group in preparation,aseptic technique,and puncture skills(P<0.05).In Mini-CEX assessments,the combined group excelled in medical interview skills,humanistic care,clinical diagnosis,and overall clinical ability(P<0.05).Survey results indicated higher agreement on improved clinical thinking and operational abilities in the combined group(P<0.05).Conclusion This teaching mode is obviously better than the traditional teaching group,and it is leading in clinical ability and skill operation.Students have achieved remarkable teaching results in practice through this teaching mode.
