Brief Summary

Training in TEE is based on hands-on training in the operation room which is time consuming and therefore its use and experience is limited among anesthesiologists. Recent studies demonstrate that simulation-based education is also superior to a conventional didactic system and superior to hands-on teaching in the OR in terms of theoretical knowledge in echocardiography. So far there is no study evaluating the study effect in obtaining the 11 basic TEE views as recommended by the American Society of Echocardiography (ASE) and the Society of Cardiovascular Anesthesiologists (SCA) between simulator training and training in the operation room in residents with no prior knowledge of echocardiography. The basic TEE examination focus on the 11 most relevant views. Therefore the investigators want to assess if there is a difference in the study effect in obtaining the 11 basic TEE views and also in theoretical knowledge in 3 groups of residents with no prior knowledge of echocardiography: the simulation group (CAE Vimedix Simulator), the hands-on OR group and the online group (http://pie.med.utoronto.ca/TEE/). prospective randomized single-center study. The investigators want to include 51 anaesthesia residents (17 per group) in their first or second year of training with no prior knowledge of echocardiography in this randomized, Controlled single-centre study. The investigators want to assess the pre- and post training scores of the theoretical multiple choice test and the practical test in all 3 groups. The multiple choice test consists of 50 questions with 1 point per question (max. 50 points) and the practical test is an evaluation of 11 basic perioperative TEE examination on the simulator (CAE Vimedix Simulator). Each view is evaluated on a scale of 0 to 10 according to predetermined criteria including image angle, overall clarity and visualization of 3 major anatomic structures pertinent to each view. Each view can receive a maximum score of 10 and each study a maximum of 109 (ME asc. aortic LAX has only 2 main structures). Further the time to adjust each view and the time to complete the basic TEE Examination will be assessed.

Interventions

theoretical test OTHER

The theoretical test is a multiple choice test which consists of 50 questions with 1 point per question (max. 50 points). It will be done before the teaching, after the 2 teaching sessions and 3 Months after the study

practical test OTHER

The practical test is an evaluation of 11 basic perioperative TEE examination on the simulator (CAE Vimedix Simulator). Each view is evaluated on a scale of 0 to 10 according to predetermined criteria including image angle, overall clarity and visualization of 3 major anatomic structures pertinent to each view. Each view can receive a maximum score of 10 and each study a maximum of 109 (ME asc. aortic LAX has only 2 main structures). It will be done after the first and second teaching session, and 3 Months after the study.
