模拟教学方法在住院医师产前超声技能培训中的应用

Application of simulation teaching method in prenatal ultrasound skills training for residents

目的探讨模拟教学方法在住院医师产前超声技能培训中的应用效果。方法采用试验对照方法。2019年9月至11月,选取中南大学湘雅三医院超声科的22名住院医师规范化培训学员作为研究对象,采用随机数字法将其平分为试验组和对照组。在产前超声技能培训中,试验组学员采用模拟教学方法,对照组学员采用志愿者孕妇教学方法。培训前后两组学员均接受产前超声技能考核,培训后超声技能考核完成后,采用自编问卷对试验组学员进行调查。结果培训前后试验组学员超声技能考核成绩的变化量高于对照组学员[(23.35±9.11)分比(9.90±8.42)分,t=3.597,P<0.01]。问卷调查结果显示,试验组有10名及以上学员认为产科超声模拟器图像显示清晰,模拟教学方法能够帮助形成规范的检查顺序、能够帮助学员提升临床检查能力。结论模拟教学方法有助于提高学员的产前超声技能水平,学员对模拟教学方法反馈良好。

Objective To explore the application effect of simulation teaching method in prenatal ultrasound skills training for residents.Methods A randomized controlled trial design method was used in this study.From September 2019 to November 2019,22 residents who studied in the ultrasound department of the Third Xiangya Hospital of Central South University were recruited and they were randomized divided into experimental group and control group with 11 in each.The experimental group residents were trained with simulation teaching method,while the control group residents were trained with volunteer pregnant woman method.Before and after the training,both groups were examined by prenatal ultrasound skills assessment.After the completion of the assessment,the experimental group residents were conducted a questionnaire survey.Results The improvement of the test scores of the experimental group residents was greater than that of the control group[(23.35±9.11)vs.(9.90±8.42),t=3.597,P<0.01].The questionnaire survey results showed that 10 or more residents in experimental group thought thatthe images of obstetric ultrasound simulator were clearly displayed,the simulation teaching method could help form a standardized examination sequence and help to improve the clinical examination capabilities.Conclusions Simulation teaching method is helpful to improve residents'prenatal ultrasound skills.The overall feedback from residents to this training mode is good.
