重症超声心动图(critical care echocardiography,CCE)对于评估重症患者的血流动力学状态具有重要作用,但是目前临床应用仍存在不足。本研究旨在探讨超声心动图模拟器在内科医师CCE培训中的应用效果。于2023年5至6月,对北京大学第三医院35名内科医师进行CCE培训,包括1小时理论授课和3小时模拟教学。培训结果显示,有33名(94.3%)学员能够采集出所有5种超声心动图切面;学员对低血容量的超声图像识别的正确率达到100.0%。以简单随机方法抽取16名学员,培训后1周为标准化病人进行超声心动图检查,结果显示,所有学员均在标准化病人上成功完成了超声心动图切面采集。培训实践证明,超声心动图模拟器在内科医师CCE的培训中取得了良好的效果,学员可以在较短时间内基本掌握切面采集和图像识别。
Critical care echocardiography (CCE) plays a vital role in assessing the hemodynamic status of critically ill patients, but there is still a significant deficiency in its clinical application. This study explores the application of echocardiography simulators in CCE training among internists. From May to June 2023, CCE training was conducted for 35 internists in Peking University Third Hospital, which included 1 hour of knowledge teaching and 3 hours of simulated training. The results showed that 33(94.3%) trainees were able to obtain all 5 echocardiography views; the accuracy rate in identifying low blood volume was 100.0%. A simple random sampling method was used to select 16 trainees, who performed echocardiographic on standardized patients one week after the training. The results indicated that all trainees successfully completed the acquisition of echocardiography views on the standardized patients. The training practice demonstrated that the echocardiographiy simulator achieved favorable outcomes in the training of CCE for internists. Trainees could basically master the acquisition of echocardiography views and identification of the echocardiography images within a short period.
