Simulator Teaching of Cardiopulmonary Bypass Complications: A Prospective, Randomized Study
2016
Objective Complications of cardiopulmonary bypass (CPB) are rare, but life-threatening events that need prompt and rehearsed actions involving a team. This is not adequately taught to cardiothoracic surgical trainees. The objective of this study was to assess the knowledge of cardiothoracic trainees required to manage these events after simulation-based vs. lecture-based teaching. Participants and Design Totally, 17 cardiac surgical trainees with no formal teaching in intraoperative complications of CPB management were randomly assigned by computer to either a study group receiving simulation-based complications of CPB teaching via the Orpheus simulator ( n = 9) or a control group receiving complications of CPB teaching via a lecture ( n = 8). Each subject undertook a written test comprising 20 multiple choice questions on complications of CPB before and after teaching. Trainees were then asked to rate their satisfaction with each session from 1 to 5, with 5 being most satisfied. Setting St George Simulation and Clinical Skills Laboratory, St George’s Hospital, London. Results There was no significant difference in the pretest scores between the 2 groups (p = 0.29). After teaching, both groups showed a statistically significant improvement in their knowledge (p Conclusion Despite the familiarity with CPB during surgery, the simulation group performed at least as well as the lecture group. Cardiothoracic trainees would benefit from formal teaching of complications of CPB management via either learning modality being incorporated into their training.
