Pericardial Tamponade in a Patient With a History of Pneumonectomy.

Abstract

Shock is the clinical presentation of circulatory failure with impaired perfusion that results in inadequate cellular oxygen utilization. Treatment requires properly identifying the type of shock that is impacting the patient (obstructive, distributive, cardiogenic, and/or hypovolemic). Complex cases may involve numerous contributors to each type of shock and/or multiple types of shock which can present interesting diagnostic and management challenges to the clinician. In this case report, we present a 54-year-old male with a remote history of a right lung pneumonectomy presenting with multifactorial shock including cardiac tamponade, with initial compression of the expanding pericardial effusion by the postoperative fluid accumulation within the right hemithorax. While in the emergency department, the patient gradually became hypotensive with worsening tachycardia and dyspnea. A bedside echocardiogram revealed an increase in size of the pericardial effusion. An emergent ultrasound-guided pericardial drain was inserted with gradual improvement of his hemodynamics followed by placement of thoracostomy tube. This unique case highlights the importance of utilizing point-of-care ultrasound along with emergent intervention in critical resuscitation.
