Treating Ischemic Stroke with tPA in the ED: Time is Brain

Ischemic stroke is an emergent and devastating neurologic disorder, and is a leading cause of both death and disability in the United States. With each minute of brain ischemia, two million neurons are irreversibly damaged. Total ischemic time is linked to functional outcome, and therefore, the role of the Emergency Department is paramount in the management of these patients. Fibrinolytic therapy has become a mainstay of therapy for acute stroke, but guidelines for the use of tPA are dynamic, and often even controversial. When you identify someone with symptoms of stroke, what is your approach to determining if a patient should receive tPA?

Deciphering Acid-Base Disorders

AcidBaseDerangements in acid-base status are commonly discovered on routine emergency department evaluation and often suggest the presence of severe underlying disease. Many acute conditions can disrupt homeostatic mechanisms used to buffer and excrete acid, and these changes may necessitate immediate intervention. When you discover a patient with an abnormal pH, what is your approach to the diagnosis?

Choosing the right vasopressor agent in hypotension

HypotensionExpertPeerReviewStamp2x200The incidence of critical illness in the ED is rising, with greater than 1 million ED patients requiring emergent resuscitation each year. In addition to definitive airway management, hemodynamic support is among the most important life-saving interventions implemented by emergency physicians. When a patient develops persistent hypotension, what is your approach to choosing the right medication for hemodynamic support?

Alarms from the ventilator: Troubleshooting high peak pressures

VentilatorAirway management is one of the defining skills of an emergency physician, but our role in the care of intubated patients may continue long after endotracheal tube placement is confirmed. In mechanically ventilated patients, acute elevations in airways pressures can be triggered by both benign and life-threatening causes. When the ventilator alarms, do you know how to tell the difference? What is your approach in troubleshooting the potential problems?
