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.

Helicopter Emergency Medical Services (HEMS) dispatch currently depends on predefined protocols, on first responders' initial assessment, or on medical direction decision in some states. National guidelines do not provide recommendations concerning prehospital time criteria. ⋯ In adult patients with blunt trauma, HEMS transport was associated with overall improved survival rates mainly in the first 30 min after injury. GEMS transport, however, had a survival advantage in the 61- to 90-min total prehospital time interval.

Mild traumatic brain injury (TBI) is a common event and antiplatelet therapy might represent a risk factor for bleeding. ⋯ Patients on antiplatelet therapy have an increased risk of ICH after mild TBI compared with patients not on antithrombotic therapy. However, the risk is just slightly increased, and the need to perform a computed tomography scan in patients on antiplatelet therapy after a mild TBI should be evaluated case by case, but always considered in patients with other risk factors.

Static Ultrasound Guidance VS. Anatomical Landmarks for Subclavian Vein Puncture in the Intensive Care Unit: A Pilot Randomized Controlled Study.
Subclavian vein puncture is commonly used in the intensive care unit (ICU) but is associated with complications. ⋯ Static ultrasound-guided subclavian vein puncture is superior to the traditional landmark-guided approach for critically ill patients in the ICU. It is suggested that static ultrasound-guided puncture techniques should be considered for subclavian vein puncture in the ICU.

The Bezold-Jarisch reflex is a depressor reflex of the heart due to the preferential distribution of vagal nerves in the inferior wall of the left ventricle. We report a case of Stanford type A acute aortic dissection, in which coronary spastic angina caused the Bezold-Jarisch reflex in the acute phase. ⋯ A 53-year-old man presented with left chest pain and cold sweating. An electrocardiogram was normal and the high-sensitivity cardiac troponin T level was negative. A diagnosis of Stanford type A acute aortic dissection was made based on computed tomography (CT); there was no evidence of ischemic heart disease on coronary CT angiogram obtained simultaneously. While waiting for emergency surgical repair, chest pain worsened, followed by bradycardia and hypotension, along with ST-segment elevations in the inferior leads, all of which were resolved by conservative treatment. During surgery, no evidence to suggest an extension of the dissection to the ostium of the right coronary artery was observed. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: The present case highlights the importance of recognizing the Bezold-Jarisch reflex because this depressor reflex may require different management than other conditions.
