Orbital Compartment Syndrome and Irreversible Blindness Related to Orbital Varix Thrombosis: A Case Report.
Orbital compartment syndrome (OCS) is an ocular emergency that can severely threaten the visual potential. The most common etiologies include facial trauma-related orbital wall fractures and postoperative bleeding within the orbit. Nontraumatic cases were also reported sporadically, although they are rare. The orbital volume limits the compliance to expand when space-occupying lesions develop. Both direct compression of the optic nerve and depleted perfusion from elevated intraorbital pressure subsequently lead to ischemic optic neuropathy and vision loss. ⋯ A 74-year-old man experienced headache, bulging left eye, dull pain, vision loss, nausea, and vomiting within 1 day. Computed tomography and magnetic resonance imaging revealed a heterogeneous mass extending from the orbital apex and connected with the ophthalmic vein. Lateral canthotomy and cantholysis were performed at bedside for emergent orbital decompression. The proptosis and pain relieved after surgery, but visual loss remained irreversible. Surgical exploration was conducted and pathology proved the diagnosis of varix of the ophthalmic vein with thrombosis. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Clinicians should be aware of the presentation of OCS and perform timely orbital decompression, which could reverse visual impairment. These patients might also benefit from immediate consultants with ophthalmologists and radiologists.

Case Reports
Pseudomembranous Tracheobronchitis With Severe Tracheal Stenosis and Masked Bronchial Obstruction.
Pseudomembranous tracheobronchitis (PMTB) is a rare condition characterized by the formation of endobronchial pseudomembranes. PMTB overlaps with necrotizing tracheobronchitis or plastic bronchitis. The reported infectious etiology mainly includes invasive aspergillosis. PMTB can cause serious airway obstruction; however, urgent tracheotomy is rarely required. ⋯ A 46-year-old woman was transferred to the emergency department (ED) with a 1-week history of progressive dyspnea and cough that was preceded by fever and sore throat. She was previously healthy except for a 20-year history of mild palmoplantar pustulosis. Stridor was evident. Nasolaryngoscopy performed in the ED revealed severe tracheal stenosis caused primarily by mucosal edema and secondarily by pseudomembranes. Initially, tracheitis was considered the sole cause of dyspnea. Although she underwent urgent tracheotomy to prevent asphyxia, her respiration deteriorated progressively. Bronchoscopy revealed massive pseudomembranes obstructing the bilateral bronchi, which led to the clinical diagnosis of PMTB. Subsequent toilet bronchoscopy markedly improved her ventilation. The causative pathogen was not identified despite extensive work-up, including molecular biological testing. Histopathologic examination of the pseudomembranes revealed fibrin with abundant neutrophils, which was consistent with PMTB. Associated conditions, including immunodeficiency, were not found. Her condition improved with antibiotics and repeated toilet bronchoscopy. WHY SHOULD AN EMERGENCY PHYSICIANS BE AWARE OF THIS?: PMTB is an important differential diagnosis of airway emergencies. PMTB can present with critical edematous tracheal stenosis and masked bronchial pseudomembranous obstruction. Emergency physicians should include PMTB in the differential diagnosis in adult patients with acute central airway obstruction because it requires prompt multimodal treatment.

A Case of Covid-19 Diagnosed at Home With Portable Ultrasound and Confirmed With Home Serology Test.
The coronavirus disease 2019 (COVID-19) pandemic has pushed us to find better ways to accurately diagnose what can be an elusory disease, preferably in a way that limits exposure to others. The potential for home diagnosis and monitoring could reduce infectious risk for other patients and health care providers, limit use of finite hospital resources, and enable better social distancing and isolation practices. ⋯ Novel times call for novel solutions and our case demonstrates one possible path for home diagnosis and monitoring of COVID-19. The tools used, namely ultrasound and pulse oximetry, should be familiar to most emergency physicians. Ultrasound in particular was helpful in eliminating other potential diagnoses, such as pulmonary embolus.

Emergency medical services (EMS) agencies with higher field termination-of-resuscitation (TOR) rates tend to have higher survival rates from out-of-hospital cardiac arrest (OHCA). Whether EMS agencies can improve survival rates through efforts to focus on resuscitation on scene and optimize TOR rates is unknown. ⋯ This study described the association between an educational intervention focusing on optimization of resuscitation on scene and OHCA process and outcome measures. Field termination has the potential to serve as a surrogate marker for aggressively treating OHCA patients on scene.

Observational Study
Impact of Electronic Medical Record Alerts on Emergency Physician Workflow and Medical Management.
Electronic medical record (EMR) alerts are automated messages that notify the physician of important information. However, little is known about how EMR alerts affect the workflow and decision-making of emergency physicians (EPs). ⋯ EPs frequently receive EMR alerts, however, most alerts were not perceived to impact patient care. These alerts contribute to the high volume of interruptions EPs must contend with in the clinical environment of the ED.
