Background: We report a case of refractory vasoplegia after nimodipine administration that was unresponsive to triple vasopressor therapy and was rescued by IV hydroxocobalamin. Case Summary: An 84-year-old male presented comatose from a subarachnoid hemorrhage and developed severe hypotension unresponsive to three vasopressors following a single dose of enteral nimodipine. Multisystem point-of-care ultrasonography ruled out alternate etiologies of shock, indicating that this was likely a vasoplegic state caused by nimodipine...

Point-of-care ultrasonography (POCUS) was initially limited to simple applications such as diagnosing ascites, sampling pleural fluid and guiding venous access. Use of POCUS is currently on the rise. As radiologists, we endorse the use of ultrasonography as the stethoscope of the future, but we make some critical comments. The interpretation of ultrasonographic findings can have far-reaching therapeutic implications. The patient is therefore entitled to maximum ultrasonographic expertise. Intensive hands-on training starting in early medical school is mandatory and central archiving of ultrasonographic images and reports is essential...

In 2017, there were ≈47,600 opioid overdose-related deaths in the United States. US emergency department (ED) visits for suspected opioid overdose increased by 30% between July 2016 and September 2017.2 The current US opioid epidemic makes it critical for emergency physicians to be aware of common and uncommon infectious and non-infectious complications of injection drug use. Point-of-care ultrasound has become a widely available, non-invasive diagnostic tool in EDs across the United States and worldwide...

Right-to-left pulmonary and cardiac shunts (RLS) are important causes of refractory hypoxia in the critically-ill perioperative patient. Using a point-of-care ultrasound (POCUS) agitated saline bubble study for an early diagnosis allows patients with clinically significant RLSs to receive expedited therapy. This narrative review discusses the principles of agitated saline ultrasonography as well as the role of POCUS in detecting the most common RLS types seen in the intensive care unit, including patent foramen ovale, atrial septal defects, and pulmonary arterio-venous malformations...

Point of care ultrasonography (POCUS) is a specific form of ultrasonography that aims to quickly rule in or out specific abnormalities with a high impact on diagnostic or therapeutic management as an adjunct to physical examination. As such, it is of great value to every physician who performs physical examinations, especially if there is an acute problem that may involve several organ systems.

We report the case of a 71-year-old male with Crohn's disease, shortness of breath, and chest pain that highlights cardiac involvement in inflammatory bowel disease and the role of point-of-care ultrasonography using an alternate cardiac ultrasound window in making the diagnosis of Crohn's pericarditis. The role of ultrasonography in diagnosis and management of inflammatory bowel disease focuses primarily on intestinal pathology. Cardiac involvement is a rare but clinically impactful extraintestinal manifestation, the diagnosis of which benefits from ultrasonography if the clinician performing and interpreting the exam is aware of the possibility and understands the potential value of whole-body ultrasonography as part of a physical exam...

STUDY OBJECTIVE: Acute chest syndrome is a leading cause of mortality in patients with sickle cell disease (SCD). Because early detection of acute chest syndrome is directly tied to prognosis, young patients with SCD undergo countless chest radiography screenings throughout their lifetime for commonly occurring acute chest syndrome risk factors such as fever, chest pain, or cough. Chest radiography is not an ideal screening method because it is associated with radiation exposure, which accumulates with repeated imaging...

Takotsubo syndrome (TS) is an incompletely understood, transient dysfunction of the left ventricle. While acute coronary syndrome must be at the forefront of the differential diagnosis and ruled out appropriately, the possibility of TS can be identified early with point-of-care ultrasonography. The formal diagnostic criteria for TS rely on invasive diagnostic procedures and resolution of symptoms, typically relegating it to a diagnosis of exclusion. However, the acute complications are potentially lethal, and rapid identification is therefore beneficial because these patients can be risk-stratified to higher levels of care...
