Rapid tranquilization of agitated patients can prevent injuries and expedite care. Whereas antipsychotics and benzodiazepines are commonly used for this purpose, ketamine has been suggested as an alternative. ⋯ Ketamine provides rapid sedation for undifferentiated agitated patients and is associated with higher intubation rates when used by ground Emergency Medical Services paramedics, compared with ED or air medical transport patients. Other side effects are common but usually self-limiting.

Acute heart failure (AHF) is a common presentation to the emergency department (ED), with the potential to cause significant morbidity and mortality. It is important to tailor treatments to the appropriate type of heart failure. ⋯ AHF is a condition that requires rapid assessment and management. Understanding the appropriate management strategy can allow for more targeted treatment and improved outcomes.

Rupture of the distal biceps tendon is seen in both the emergency and primary care settings. It most commonly occurs after excessive tension exerted on a flexed forearm. Knowledge of the anatomy, pathophysiology, historical and physical examination findings, as well as the workup, diagnosis, and treatment of distal biceps tendon rupture are essential in achieving good outcomes, as delays in treatment can make surgical repair more challenging and less efficacious. ⋯ A healthy 38-year-old male presented to his primary care physician complaining of right elbow pain that started while lifting an all-terrain vehicle into a truck. On physical examination, the patient had obvious deformity of the distal upper arm, as well as a positive squeeze test. Magnetic resonance imaging confirmed the presence of complete rupture of the distal biceps brachii tendon and the patient was referred to orthopedic surgery for evaluation. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Prompt diagnosis and referral to orthopedic surgery optimizes outcomes and minimizes complications after distal biceps brachii tendon rupture. Oftentimes, gross examination shows obvious deformity of the distal upper arm, but when swelling, mobility limitations, or patient anatomy hinder this physical examination finding, the diagnosis can be missed. Knowledgeable emergency physicians can perform a physical examination and other diagnostic tests that can confirm or rule out a diagnosis in order to achieve the best outcomes for patients.

There are 215 families of plants that contain insoluble needle-shaped calcium oxalate crystals on the surface of their tissues. Upon mucosal contact, injury can cause extreme pain, soft-tissue swelling, salivation, dysphagia, and even aphonia. This presentation can resemble angioedema or anaphylaxis. ⋯ A 55-year-old Asian female presented to the emergency department complaining of oral pain, swelling, and numbness. Her family reported that she began to experience sharp pain of the tongue and lips immediately after eating "elephant root." Physical examination revealed a patient sitting in an upright position, leaning forward with pooling secretions. She had few lingual petechiae, a subtle diffuse erythema, and mild edema of the lower lip. Due to pain, she was unable to speak and swallow. Her vitals remained within normal limits. The patient was taking lisinopril for hypertension. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Injury by calcium oxalate crystals is a relatively common occurrence that will present to the emergency department. Although most exposures are benign, patients can develop critical illness, requiring emergent therapies and airway management. Due to the nature of presentation, exposure can easily be misdiagnosed as anaphylaxis or hereditary and drug-induced angioedema. Severe pain and the temporal relationship to plant ingestion distinguish insoluble calcium oxalate crystal exposure from these alternative causes of angioedema. There is minimal evidence-based data evaluating treatment of these injuries. Standard treatment regimen includes a local anesthetic, corticosteroids, opioids, and antihistaminergic agents. Given the relative low cost, ease of administration, and benign adverse effect profile, sodium bicarbonate rinse may have a role as an adjunct therapy, however, research is needed.
