Ultrasound For The Win! Case – 101M with Altered Mental Status #US4TW
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 this case, a 101-year-old man presents after being found down with altered mental status. [+]
Ketamine for Excited Delirium Syndrome
Excited delirium syndrome is defined as “a syndrome of uncertain etiology characterized by delirium, agitation, and hyperadrenergic autonomic dysfunction”.1 You may have encountered a patient like this in the ED or prehospital setting. Although the etiology is impossible to determine in many cases, stimulant abuse and other drugs are involved in a majority of cases. An 8% mortality has been ascribed to Excited Delirium Syndrome, resulting from hyperthermia, severe metabolic acidosis, and cardiovascular collapse. [+]
Trick of the Trade: IV-Push Antibiotics in the ED
Limited intravenous access is a common conundrum in the Emergency Department, with heavy implications for medication administration. Of particular concern, are the profoundly septic patients that necessitate multiple timely therapies, which require tying up a line – fluids, pressors, several antibiotics, etc. The shift away from less central line (i.e. triple lumen) placement for initial resuscitation, may serve to further exacerbate this issue.

Vancomycin Loading Doses in Pediatric Patients: A Missed Opportunity?
In January 2014, ALiEM featured a must-read post by Bryan Hayes regarding proper dosing of vancomycin in the emergency department, including a special note related to the recommendations regarding consideration of loading doses of vancomycin ranging from 25 to 30 mg/kg in adult patients who are critically ill with a high suspicion for MRSA infection.

AIR Series: GU/Renal Module 2015
Welcome to the eighth ALiEM Approved Instructional Resources (AIR) Module! In an effort to reward our residents for the reading and learning they are already doing online we have created an Individual Interactive Instruction (III) opportunity utilizing FOAM resources for U.S. Emergency Medicine residents. For each module, the AIR board curates and scores a list of blogs and podcasts. A quiz is available to complete after each module to obtain residency conference credit. Once completed, your name and institution will be logged into our private database, which participating residency program directors can access to provide proof of completion. [+]
Four reasons not to order a Rapid Flu test
Every year emergency departments are inundated with cases of influenza-like illness. Rapid flu testing (RFT) offers the promise of a quick and relatively noninvasive rapid diagnostic test. However, the use of this test has significant limitations that can lead to increased risk for both the patient and the provider. [+]
Hyperkalemia Management: Preventing Hypoglycemia From Insulin
Insulin remains one of the cornerstones of early severe hyperkalemia management. Insulin works via a complex process to temporarily shift potassium intracellularly. Though insulin certainly lowers plasma potassium concentrations, we often underestimate the hypoglycemic potential of a 10 unit IV insulin dose in this setting. The purpose of this post is to highlight the need for proper supplemental glucose and blood glucose monitoring when treating hyperkalemia with insulin. This is such an important medication safety issue, the Institute for Safe Medication Practices (ISMP) highlighted it in a February 2018 Safety Alert. [+]
Trick of the Trade: TRUST ultrasound confirmation of pediatric endotracheal tube placement
Following intubation the confirmation of endotracheal tube placement and depth is essential. While dynamic etCO2 monitoring has revolutionized the confirmation of endotracheal placement, there are still several circumstances in which this modality may be misleading (e.g. prolonged arrest, severe status asthmaticus/PE/pulmonary edema, etCO2 detector contamination with drugs/gastric contents). Additionally, EtCO2 detectors cannot confirm appropriate endotracheal tube depth, leading to delayed recognition of mainstem placement. [+]
Diagnose on Sight: Lip Swelling
Case: A 24 year old male presents with right sided lip swelling that began several hours ago. This is the second time he has had this type of swelling. His mother has also had this before. He currently has no urticaria, dyspnea, wheezing, or stridor. What is the cause of this patient’s symptoms? [+]
A cost-effective, two-layer wound closure task trainer
Performing a two layer wound closure can be a challenging procedure in the Emergency Department for clinicians with limited wound care experience. Challenges include suture choice, suture placement, and the technique of burying the knot in the deep layer of the wound, and the availability of ready ‘volunteers’ with complex wounds willing to let novices practice on them. Commercially available suture models are expensive, and can be cumbersome to store, and difficult to obtain in a timely manner to provide the learner with opportunities to practice prior to wound repair on a patient in the department.
