The novel coronavirus SARS-CoV-2 (COVID-19) pandemic has created diagnostic uncertainty with regards to distinguishing this infection from pulmonary embolism (PE). Although there appears to be an increased incidence of thromboembolic disease in patients with COVID-19 infection, recommendations regarding anticoagulation are lacking. We present the case of a 61-year-old woman with clinically significant venous and arterial thromboemboli in the setting of COVID-19 infection requiring tissue plasminogen activator (tPA).

To determine if following fluid resuscitation recommendations in the Surviving Sepsis Campaign guidelines affects hospital length of stay (LOS) in chronic kidney disease (CKD) patients who present to the emergency department with sepsis-induced hypotension or septic shock. ⋯ The results of this single-center, retrospective study indicate that CKD patients who receive guideline-directed fluid resuscitation (≥27 mL/kg) for sepsis-induced hypotension or septic shock experience a longer hospital LOS compared to those who receive a reduced initial fluid volume.

Emergency department (ED) crowding is associated with increased mortality and delays in care. We developed a rapid admission pathway targeting critically-ill trauma patients in the ED. This study investigates the sustainability of the pathway, as well as its effectiveness in times of increased ED crowding. ⋯ This study found that a streamlined process to admit critically-ill trauma patients is sustainable and associated with reduction in ED LOS. As ED crowding remains pervasive, these findings support restructured care processes to limit prolonged ED boarding times for critically-ill patients.

The COVID19 crisis has provided a portal to revisit and understand qualities of screening tests and the importance of Bayes' theorem in understanding how to interpret results and implications of next actions.

Hyperoxia, the delivery of high levels of supplemental oxygen (sO2) despite normoxia, may increase cerebral oxygenation to penumbral tissue and improve stroke outcomes. However, it may also alter peripheral hemodynamic profiles with potential negative effects on cerebral blood flow (CBF). This study examines the hemodynamic consequences of prehospital sO2 in stroke. ⋯ Prehospital-initiated hyperoxia for acute stroke is associated with a small, but significant decrease in average ED MAP, without changes in heart rate, compared to normoxia. While limited by the inability to link changes in peripheral hemodynamical profiles directly to changes in CBF, this study suggests that hyperoxia may result in a relative hypotension. Further studies are needed to determine if this small change in peripheral vascular resistance translates into a clinically significant reduced CBF.
