Epinephrine effectiveness and safety are still questioned. It is well known that the effect of epinephrine varies depending on patients' rhythm and time to injection. ⋯ In shockable and nonshockable rhythms, epinephrine does not seem to have any benefit on D30 survival. These results underscore the need to perform further studies to define the optimal conditions for using epinephrine in patients with OHCA.

Meta Analysis
Double Defibrillation for Refractory In- and Out-of-Hospital Cardiac Arrest: A Systematic Review and Meta-Analysis.
Double/dual defibrillation (DD) has been proposed as an alternative treatment for refractory ventricular fibrillation (VF). This topic has been poorly researched and data on survival rates are limited. ⋯ DD did not improve any outcomes of interest. Therefore, it is imperative that a well-designed study in this area be conducted. Ideally, conducting a randomized controlled trial in this population should be attempted to obtain a higher level of scientific evidence.

Successful airway management is critical to the practice of emergency medicine. Thus, emergency physicians must be ready to optimize and prepare for airway management in critically ill patients with a wide range of physiologic challenges. Challenges in airway management commonly encountered in the emergency department are discussed using a pearl and pitfall discussion in this second part of a 2-part series. ⋯ This narrative review discusses the pearls and pitfalls of commonly encountered physiologic high-risk intubations with a focus on the emergency clinician.

Case Reports
A Rare Case of Spontaneous Pseudo-Aneurysm Rupture of an Extra-Anatomical Axillo-Femoral Bypass Graft: A Case Report.
Sudden onset of chest wall bulging is a rare chief symptom in the emergency department (ED). However, it may represent life-threatening diseases, such as tumor bleeding, aneurysm rupture, or subcutaneous emphysema. ⋯ We present an 89-year-old woman who visited our ED with a chief symptom of abrupt bulging of the right chest wall accompanied with severe pain. The patient had a history of peripheral artery disease and 10-year post-extra-anatomical axillo-femoral bypass (AxFB) status. After several examinations, the patient was diagnosed as having spontaneous pseudo-aneurysm rupture of an extra-anatomical AxFB graft. Emergency endovascular intervention with stent insertion was performed immediately, and the patient was eventually discharged successfully. WHY SHOULD EMERGENCY PHYSICIANS BE AWARE OF THIS?: Although spontaneous pseudo-aneurysm rupture of an extra-anatomical AxFB graft is rare, the disease may consequently lead to a fatal outcome once misdiagnosed, and prompt intervention is warranted. Therefore, we should always consider the differential diagnosis of this disease in patients with a bulging chest wall and history of AxFB graft placement.

Case Reports
Foreign Body Esophageal Perforation Leading to Multifocal Brain Abscesses: A Case Report.
Among those aged 5 years or younger, foreign bodies are the fourth most common pediatric exposure reported to the American Association of Poison Control Centers. Although the majority of ingested foreign bodies pass through the gastrointestinal tract without complication, those that do not spontaneously pass can lead to a number of serious complications, such as gastrointestinal obstruction or perforation, which can be complicated by bleeding from aortoesophageal fistula, secondary mediastinitis, peritonitis, esophageal or gastrointestinal fistula formation, and abscesses. ⋯ We present the case of a 10-month-old child who presented with new-onset focal seizure in the setting of multiple brain abscesses, ultimately found to be due to esophageal perforation from a retained, metallic esophageal foreign body. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Foreign bodies that are retained for longer than 24 h after ingestion have been associated with a higher risk of complications because they are less likely to pass spontaneously through the gastrointestinal tract. Early identification and removal of foreign bodies is necessary to prevent subsequent complications. In patients who have a subacute history of cough, gagging, vomiting, and decreased oral intake with an otherwise unknown cause, foreign-body ingestion or aspiration should be considered. In addition, central nervous system abscess and infection should be considered in patients with concerns about previous foreign body ingestion or aspiration and who are newly presenting with fever, focal neurologic changes, and irritability.
