Review Case Reports
Arterial Gas Emboli Secondary to Portal Venous Gas Diagnosed With Point-of-Care Ultrasound: Case Report and Literature Review.
Portal venous gas (PVG) is a rarely observed clinical finding generally associated with intestinal ischemia. The proper clinical response to the finding of PVG depends somewhat on the setting in which it is observed. Here we describe a case in which extensive arterial gas emboli (AGE) were encountered during point-of-care ultrasound (POCUS) and subsequent computed tomography (CT) identified PVG secondary to gastric wall ischemia as the likely source. ⋯ A 69-year-old woman with history of metastatic colon cancer presented to the emergency department (ED) with altered mental status. On arrival, she was hypotensive, hypothermic, cachectic, and with abdominal distension. POCUS was performed to evaluate the source of the patient's hypotension, revealing the presence of PVG, as well as gas bubbles in all four chambers of the heart and the aorta. CT scan revealed gastric wall ischemia and confirmed the presence of significant air emboli throughout the portal venous system. Given the overall poor prognosis, the decision was made to forego further chemotherapy or surgery and the patient died later that week while under hospice care. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: AGE can occur in the setting of PVG. This may cause multi-organ failure by disrupting blood flow to organs, especially in patients with circulatory dysfunction, such as shock. Depending on the setting in which it is diagnosed, early detection of PVG may expedite earlier assessments of a patient's negative prognosis or initiation of attempted life-saving treatment. In this case report, we show that POCUS can be used to obtain an expedited diagnosis in a critically ill patient.

Randomized Controlled Trial
Ultrasound Guidance Versus Landmark-Guided Palpation for Radial Arterial Line Placement by Novice Emergency Medicine Interns: A Randomized Controlled Trial.
More than 10 million arterial lines are placed annually worldwide, many of which happen in the emergency department. Before the introduction of point-of-care ultrasound, landmark-guided palpation (LMGP) was considered standard of care. ⋯ USG improved first-pass and overall success of radial arterial line cannulation while reducing time to access and attempts when used by novice emergency medicine interns.

During the coronavirus disease 2019 (COVID-19) pandemic, healthcare systems in many regions of the country were being overwhelmed by large numbers of patients needing care. In this paper, we discuss use of an external emergency department (ED) site by a hospital system based in Charlotte, North Carolina to address concerns of a local surge similar to those seen around the country. ⋯ External expansion of the ED is an important strategy that can allow hospitals to accommodate potentially infectious patients while maintaining appropriate isolation and rapid throughput. Proper implementation of the right system to meet hospital-specific needs can prove effective for the healthcare system.

Case Reports
Acute Angle-Closure Glaucoma Secondary to Vitreous Hemorrhage Diagnosed with the Aid of Point-of-Care Ultrasound.
Acute angle-closure glaucoma (AACG) caused by vitreous hemorrhage is a rare complication of intravitreal injection that often leads to permanent vision loss without prompt treatment. ⋯ This is a case of vitreous hemorrhage with secondary AACG in an 80-year-old man who presented to the emergency department (ED) with pain and vision loss in his left eye after undergoing intravitreal injection to treat exudative macular degeneration. The diagnosis was made with the use of point-of-care ultrasound after intraocular pressure (IOP) was found to be significantly elevated in the left eye. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Emergency physicians should have a high level of suspicion for AACG in patients who are diagnosed with a vitreous hemorrhage after intravitreal injection and should immediately measure IOP for elevation upon presentation to the ED.

Emergency departments (EDs) need to be prepared to manage crises and disasters in both the short term and the long term. The coronavirus disease 2019 (COVID-19) pandemic has necessitated a rapid overhaul of several aspects of ED operations in preparation for a sustained response. ⋯ A crisis like the COVID-19 pandemic requires careful planning to facilitate urgent restructuring of many aspects of an ED. By sharing our departments' responses to the COVID-19 pandemic, we hope other departments can better prepare for this crisis and the next.
