A 71 year-old patient with a past medical history of hypertension, percutaneous transluminal coronary angioplasty 7 years ago, and robotic coronary artery bypass grafting of the left internal mammary artery to the left anterior descending artery 9 years ago presents with worsening dyspnea on exertion. He had a biopsy of the upper lobe of the left lung the week before. He was having a neoplastic mass evaluated. The patient presents with a soft left-sided anterior chest mass, inflating and deflating with respiration.
Amoxicillin is a penicillin derivative antibiotic against susceptible gram positive and gram negative bacteria. It has reasonable coverage for most upper respiratory infections and is used as prophylaxis for asplenia and bacterial endocarditis. This post aims to demystify amoxicillin treatment for common pediatric infections.(more…)
Chief Complaint: Pain with swallowing
History of Present Illness: A 43-year-old male presented to the emergency department with progressing pain upon swallowing. He described a sensation of food becoming stuck and creating a fullness in his chest. Review of symptoms was positive for dyspnea on exertion worsening over several months, but negative for cough, fevers, or weight change. He reported no medical history and had recently emigrated from Guatemala where he worked as a well digger.
End-tidal CO2 (EtCO2) monitoring is a measure of metabolism, perfusion, and ventilation. In the ED, we typically think of a EtCO2 as a marker of perfusion and ventilation. However, EtCO2 is an extremely powerful surrogate for endotracheal tube (ETT) Position, CPR Quality, Return of spontaneous circulation (ROSC), Strategies for treatment, and Termination (of CPR). Do these letters look familiar? They should! In this post we take a deep dive into each of these potential uses of EtCO2 in the ED.(more…)
Acute respiratory distress syndrome (ARDS) is a complex, life-threatening form of respiratory failure. It is responsible for almost 75,000 annual deaths in the United States.1Management remains lung-protective mechanical ventilation, an intervention that can begin in the ED. The Berlin Definition of ARDS has better predictive validity for mortality in comparison to previous definitions of ARDS.2 ALiEM Cards: ARDS, written by Dr. Michelle Lin, reviews the Berlin Definition and provides EPs with an on-shift resource to help manage critically-ill patients.
The role of extracorporeal membrane oxygenation (ECMO) in the management of acute respiratory distress syndrome (ARDS) has been a source of debate within the critical care community.1 The use of ECMO has steadily increased over the past decade;2 however, evidence to support the widespread adoption of this expensive and invasive technology is limited. As advances in ECMO technology have rapidly outpaced evidence, clinicians have been left to speculate as to ECMO’s true value. Is ECMO a promising tool to advance the care of patients with respiratory failure3 or an expensive distraction that has inappropriately supplanted evidence-based strategies?4
All who care for patients with ARDS have been eagerly awaiting the results of the Extracorporeal Membrane Oxygenation for Severe Acute Respiratory Distress Syndrome (EOLIA) trial which were recently published in May 2018’s New England Journal of Medicine.5
Computed tomography (CT) is increasingly available across U.S. Emergency Departments and has changed the practice of medicine. However, it is coupled with potential side-effects from radiation and contrast media. Emergency Medicine is beginning to make a concerted effort to identify clinical scenarios in which CT may be unnecessary, producing outcomes research and validated clinical decision rules. Renal colic and pulmonary embolism, in particular, seem amenable to this area of investigation. The ACEP E-QUAL Network podcast, a partnership with ALiEM to promote clinical practice improvements, reviewed this topic with experts Dr. Chris Moore (Emory University) and Dr. Jeffrey Kline (Indiana University). We present highlights from their discussion with Dr. Jason Woods.
