Ceftriaxone is a broad-spectrum antibiotic that is frequently administered intramuscularly (IM) in emergency medicine. However, these injections hurt — A LOT! Can we do anything to minimize the pain?
We’re all pretty familiar with the banana bag: intravenous (IV) fluids with the addition of thiamine, folic acid, multivitamins, and sometimes magnesium. Banana bags are commonly utilized in patients at risk for alcohol withdrawal symptoms or those who present to the emergency department (ED) acutely intoxicated.
Welcome to another ultrasound-based case, part of the “Ultrasound For The Win!” (#US4TW) Case Series. In this peer-reviewed case series, we focus on real clinical cases where bedside ultrasound changed management or aided in diagnoses. In today’s case, a 30-year-old male is brought in after blunt trauma from a high-speed MVC.
Case: A previously healthy 6 year old male presents with left elbow pain after wrestling with a friend. What is the diagnosis? Click on image for a larger view.
A 71 year old female presents to the ED with lethargy, fever (39.5 C), and tachypnea (RR 28 rpm). She has a long-standing history of myasthenia gravis (MG) for which she receives periodic IVIG infusions. She is accompanied by her son, who informs you that she had a recent 10-day hospital stay for weakness. A CXR reveals an infiltrate in the left lower lobe.
The decision is made to initiate antimicrobial therapy for presumed healthcare-associated pneumonia. But, which antibiotics are safe to use in a patient with severe MG?
Valproic acid is used for a variety of clinical indications including seizures, migraine prophylaxis and treatment, and bipolar disorder. A metabolite of valproic acid, thought to be propionic acid, has the ability to increase ammonia levels by inhibiting a step in the hepatic urea cycle, which may lead to valproic acid-induced hyperammonemic encephalopathy. As a result, patients treated with valproic acid presenting with signs and symptoms of acute mental status changes, increased seizure frequency, and/or gastrointestinal symptoms should be evaluated for elevated ammonia concentrations.
We commonly see patients who have some form of blunt chest trauma. This is the result of motor vehicle collisions, falls, and a myriad of other traumatic events. The decision to perform thoracic imaging can be difficult. Chest xray (CXR) and/or chest CT? In fact, studies have shown that emergency and trauma physicians often disagree 28-40.9% of the time about which patients require a chest CT following blunt trauma. 1,2
