Direct current cardioversion is a common management option for termination of tachydysrhythmias, including atrial fibrillation and atrial flutter. It is generally safe and effective with infrequent reporting of side effects. Pulmonary edema is a rare complication with reported incidence of 1-3% and mortality of 18%. Our literature search did not reveal any reported cases of postcardioversion pulmonary edema in the emergency medicine literature. ⋯ We report a case of an 80-year-old woman with a history of atypical atrial flutter on warfarin, paroxysmal atrial fibrillation, and rheumatic mitral valve disease who presented with shortness of breath 12 h after transesophageal echocardiography and subsequent direct current cardioversion with reversion to sinus rhythm. She was found to be in acute pulmonary edema. She was placed on noninvasive ventilation and diuresis with eventual symptom resolution. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Postcardioversion pulmonary edema is a rare complication that may occur after reversion to sinus rhythm. Emergency physicians should be cognizant of patients, especially those with underlying structural heart disease, who present with dyspnea after a recent cardioversion procedure or after cardioversion in the emergency department. Patients cardioverted in the emergency department may be observed for around 3 h and counseled on the development of respiratory symptoms.

One Health is a biomedical approach that aims to optimize the health of humans, animals, and the environment through interdisciplinary collaboration. Cellulitis is an infection of the dermis and subcutaneous fat that may be caused by zoonotic streptococci species. ⋯ We report a case of cellulitis caused by Streptococcus canis in a woman who was taking Etanercept. We frame the presentation within a One Health approach and urge emergency physicians to collaborate with veterinarians in the management of patients with zoonotic diseases who are discharged home. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Pets are a source for zoonotic diseases, including resistant bacteria, that pose particular risk to immunocompromised patients. Emergency physicians often discharge patients with potential zoonotic infections such as cellulitis home without a long-term, holistic care plan, according to a One Health approach. Physicians should then collaborate with veterinarians in caring for humans and animals.

Patients who present emergently with focal neurological deficits concerning for acute ischemic stroke can be extremely challenging to diagnose and treat. Unnecessary administration of thrombolytics to potential stroke patients whose symptoms are not caused by an acute ischemic stroke-stroke mimics-may result in patient harm, although the overall risk of hemorrhagic complications among stroke mimics is low. ⋯ We present a case of a stroke mimic patient with underlying psychiatric disease who was treated with intravenous alteplase on four separate occasions in four different emergency departments in the same city. Although he did not suffer hemorrhagic complications, this case highlights the importance of rapid exchange of health information across institutions to improve diagnostic quality and safety. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Increased awareness of stroke mimics by emergency physicians may improve diagnostic safety for a subset of high-risk patients. Establishing rapid cross-institutional communication pathways that are integrated into provider's workflows to convey essential patient health information has potential to improve stroke diagnostic decision-making and thus represents an important topic for health systems research in emergency medicine.

Observational Study
Novel Use of a Gas Analyzer Can Reliably Predict the Arterial Oxygen among Emergency Department Patients Undergoing Rapid Sequence Intubation.
To our knowledge, no study has assessed the correlation of fraction of inspired oxygen (FiO2) and end-tidal oxygen (EtO2) values obtained from a gas analyzer during the preoxygenation period of rapid sequence intubation (RSI) to predict partial pressure of oxygen (PaO2) among patients requiring intubation in the emergency department (ED). ⋯ Among ED patients undergoing RSI, the use of a gas analyzer to measure EtO2 and FiO2 can provide a reliable measure of the minimal PaO2 at the time of induction during the RSI phase of preoxygenation.

Case Reports
Idarucizumab for Intravenous Thrombolysis and Endovascular Thrombectomy in Acute Stroke: A Case Report.
Non-vitamin K antagonist oral anticoagulants (NOACs), such as dabigatran, are widely used to prevent ischemic stroke in patients with nonvalvular atrial fibrillation. Nonetheless, stroke occurs in 1-2% of patients, and the use of NOACs may increase the bleeding risk for patients who are receiving acute treatment of intravenous thrombolysis (IVT) or endovascular thrombectomy (EVT). Idarucizumab, a monoclonal antibody developed to bind dabigatran, has been proven safe and effective for patients with uncontrolled bleeding or for patients planning to receive emergent procedures. It is now accepted that patients taking dabigatran with recurrent stroke may benefit from IVT after idarucizumab. However, there are limited data regarding idarucizumab use in patients planning to have EVT. ⋯ We present the case of a male patient taking dabigatran who had a stroke and who was treated with idarucizumab followed by combined IVT and EVT. The patient had immediate recanalization of the occluded vessel and near total recovery of function after 3 months. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Our case report supports the evidence that patients presenting with acute ischemic stroke (AIS) despite being under dabigatran therapy should be evaluated for reversal by idarucizumab which can contribute to the eligibility for IVT as well as EVT. It has also been proved to provide better outcomes for patients with AIS. The availabilities of specific reversal agents for NOACs will probably alter the current management of patients with AIS.
