Acute Cardiac Tamponade: An Adult Simulation Case for Residents.

INTRODUCTION

This case was designed to be an interprofessional scenario to assist the learner in the approach to a patient with cardiac tamponade. This resource provides information and materials for a high-fidelity simulation scenario that is appropriate for learners at multiple levels. Each learner has the opportunity to interact with embedded patient actors. This scenario includes the opportunity to conduct a bedside echocardiogram and perform an ultrasound-guided pericardiocentesis.

METHODS

A 51-year-old female presents to the emergency department with a chief complaint of shortness of breath and with a history of cancer. Her shortness of breath evolves into tachypnea, hypoxia, altered mental status, hypotension, and shock. The physical assessment reveals hypotension, muffled heart tones, and jugular vein distension. One critical action requires the recognition of pericardial effusion on a bedside echocardiogram. The learner needs to interpret the ultrasound findings in conjunction with the physical exam findings to diagnose cardiac tamponade. An emergent ultrasound-guided pericardiocentesis is to be performed. Equipment needed includes a high-fidelity adult mannequin, the low-cost ultrasound pericardiocentesis model (or pericardocentesis model of choice), bedside ultrasound, the PowerPoint presentation containing imaging, and laboratory data.

RESULTS

A survey was completed by 23 residents who participated in this simulation. Ninety-five percent of those responding felt that this simulation in conjunction with the debriefing was effective in managing a patient presenting with undifferentiated shortness of breath and pericardial tamponade.

DISCUSSION

This case will be incorporated into the 3-year curriculum for our emergency medicine residency program and assist with evaluation of resident performance of pericardiocentesis.
