RESUMEN
BACKGROUND: Traumatic epidural hematoma (EDH) with the potential to displace the brain tissue and increase intracranial pressure (ICP), is a life-threatening condition that requires emergent intervention. In rare circumstances, Emergency Physician (EP) may have to do skull trephination to reduce the ICP as a temporary measure. SPECIFIC AIMS: To evaluate emergency medicine (EM) residents' comfort in performing emergency department (ED) burr holes and to assess their difficulties and evaluate comfort level before and after simulated EDH cases. MATERIALS AND METHODS: A 3D-printed skull, electrical and manual drills were used for the simulation. Subjective comfort level pre and post-procedure, as well as objective procedural skills and time to complete the drill, were recorded. RESULTS: Twenty EM residents participated in the simulation study. The median time to perforate through the skull was 4 s for the electric drill and 10 s for the manual drill. A comfort level of 5 and above was reported by 12 participants for the manual drill and by 17 participants for the electric drill. Six participants had mild and 2 participants had moderate observed difficulty in handling the manual and electric drill. Most participants performed both procedures successfully with one attempt only. Three participants have an overall comfort level above 5 before the simulation and 13 participants had overall comfort level above 5 post-simulation. CONCLUSION: The 3D-printed model assisted the ED burr hole simulation and the residents could perform the procedure with minimum difficulties.
