- W3000137114 abstract "Abstract Introduction and case report description A 54-year-old male with no past cardiac disease was experiencing a productive cough, fevers, chills, and shortness of breath for 3 days in the community. His dyspnea worsened significantly, and he then presented to the emergency room. He admitted to using intravenous recreational drugs. His initial vital signs included a temperature of 38.2 degrees Celsius, a heart rate of 116 beats per minute, and a blood pressure of 88/42 mmHg. He had a positive pulses paradoxus with a decrease in systolic blood pressure of 14 mmHg on inspiration. Description of the problem and procedures This presentation was consistent with cardiac tamponade. He had an emergent echocardiogram showing a large pericardial effusion in the apical-four-chamber view (Image 1, A), including collapse of the right ventricle during diastole (Image 1, B, Green Arrow). There were also fibrin strands seen in a modified parasternal long axis view (Image 1, C, Blue Arrow). He had an emergency pericardiocentesis using real-time ultrasound guidance, which drained 400 mL of thick brown purulent fluid. A pigtail catheter was inserted to allow for continued drainage. Immediately afterwards, the patient’s blood pressure normalized, and his shortness of breath improved significantly. Using the ultrasound, the physician also saw bilateral pleural effusions. The larger left pleural effusion was drained, and a pigtail catheter was inserted into the left pleural space. After confirming that there was no post-procedure left pneumothorax, the right pleural effusion was also drained. An echocardiogram after the pericardiocentesis showed a significant decrease in the size of the pericardial effusion (Image 1, D). The patient was started on broad-spectrum antibiotics, which was then narrowed after cultures from both the pericardial fluid and pleural fluid grew methicillin-susceptible Staphylococcus aureus. Discussion Cardiac tamponade results in increased compression of the cardiac chambers due to raised pericardial pressures. As it progresses, it can result in significant impairment in venous return, cardiac output, and blood pressure. This is a life-threatening condition if it is not promptly treated. In this case, the patient had a methicillin-susceptible Staphylococcus aureus empyema which spread contiguously into the pericardium and resulted in cardiac tamponade. Conclusions and implications for clinical practice This case highlights the clinical benefits of being proficient in performing a point-of-care ultrasound because a bedside echocardiogram by the physician immediately confirmed the diagnosis and allowed for safer drainage of the pericardial effusion using ultrasound guidance to decrease the chance of causing a perforation of the ventricle. Using ultrasound, the clinician was also able to promptly diagnose the pleural effusions and urgently drain them, which was necessary for achieving source control in order to fully treat the infection.
