Resuscitative ultrasonography provides rapid, repeatable, and multisystem assessment to guide diagnosis and management of critically ill patients in the emergency department (ED). Cardiac ultrasonography offers new anatomic and hemodynamic information, previously unavailable in an ED setting, whereas other applications match or exceed the speed and utility of existing tests such as chest radiograph (thoracic ultrasonography) or central venous pressure determination (inferior vena cava ultrasonography). Evolving areas of resuscitative ultrasonography include neurologic applications and transesophageal echocardiography, which promise to further enhance the role of ultrasonography in managing critical illness in the ED.

The role for temporary and durable mechanical circulatory support is rapidly expanding. As the use of these technologies continues to grow, the emergency physician has an increasing opportunity to participate in the advancement of these potentially life-saving technologies. This review discusses the current role of the intra-aortic balloon pump in cardiogenic shock, describes the complications and management strategies for the critically ill patient with a left ventricular assist device, and explores the emerging role of ECMO in the emergency department for patients presenting in refractory cardiogenic shock and cardiac arrest.

ReviewAssessment and Treatment of the Trauma Patient in Shock.
High-volume crystalloid resuscitation is associated with increased length of stay, ICU and ventilator days, and organ failure and infection rates. Rapid evaluation of a hemodynamically unstable trauma patient is vital to diagnosis and treatment of the cause of shock. CT scanning should be used liberally in trauma patients to effect decreased mortality. Nonoperative management and catheter-based interventions are becoming the standard of care in appropriately selected patients with solid organ injuries.
