Objective: Insertion of central venous catheters (CVCs) is an essential competency for emergency physicians. Ultrasound-guided (USG) insertion of CVCs has been shown to be safer than the traditional landmark technique. There is no clear consensus on effective methods for training physicians in USG insertion of CVCs. We developed and evaluated a novel educational training program in the USG technique for insertion of CVCs.
Methods: Sixteen emergency medicine residents volunteered for a pre- and postprogram evaluation study, which was approved by our research ethics board. After their previous experience was determined, each participant was videotaped inserting a USG CVC in the right internal jugular vein on models. Participants then reviewed a Web-based instructional module and had a practical session. Participants were again videotaped inserting a USG CVC. The primary outcome was the change in score before and after the training program, using an expert-validated performance evaluation tool used to review the videotaped performances in a blinded fashion. Participants also completed a questionnaire to measure their satisfaction with the training program and any change in their perceived competence.
Results: Participants ranged from residency year 1 to 5. Thirteen of 16 (81%) had never attempted USG insertion of a CVC. Participants reported that the models were realistic. Performance scores (12/19 to 13.2/19) and global ratings assessments (3.5/7 to 5.5/7) improved significantly (p < 0.01; the effect size, Cohen d = 1.12 before and 1.28 after) after the instruction. There was good interrater reliability between evaluators of the videotaped performances regarding performance scores (r = 0.68) and global rating scores (r = 0.75). All participants felt their confidence and technical skills were improved (p < 0.01) and all felt satisfied with the training program.
Conclusion: This brief innovative multimethod training program was effective in enhancing emergency medicine resident competence in USG insertion of CVCs.

Food-dependent exercise-induced anaphylaxis (FDEIA) is a specific variant of exercise-induced anaphylaxis that requires both vigorous physical activity and the ingestion of specific foods within the preceding several hours. When patients present to the emergency department (ED) with allergic reactions, careful history regarding these 2 factors is required to establish the correct diagnosis. Correct diagnosis of FDEIA will allow patients to take control of their lifestyles and avert repeated events and ED visits. Two cases of FDEIA are presented, and the diagnosis, pathophysiology and therapy of food-dependent exercise-induced anaphylaxis are reviewed.
