RATIONALE: Stress-induced cardiomyopathy (SCMP), also known as Takotsubo syndrome, is a transient cardiac condition often precipitated by severe emotional or physical stress. It is commonly mistaken for acute coronary syndrome due to similar clinical presentations. The use of point-of-care ultrasound (POCUS) provides a noninvasive, rapid diagnostic alternative that can potentially reduce the need for invasive coronary angiography, especially in emergency settings. PATIENT CONCERNS: A 26-year-old woman with type 1 diabetes presented to the emergency department following a suicidal hanging attempt...

Point of care ultrasound (POCUS) provides quick bedside assessment for diagnosing and managing life-threatening conditions in critical care medicine. There has been increasing interest in developing infrastructure to archive images, record clinical interpretation, assess quality, and recoup revenue for POCUS. We present a simple workflow by systems integration of electronic medical record, ultrasound machines, picture archiving, and communication system to facilitate POCUS documentation and billing. We recorded a trend on the number of POCUS performed before and after introduction of the structured integration...

Imaging has been demonstrated to play a crucial role in both the diagnosis and management of COVID-19. Depending on resources, pre-test probability, and risk factors for severe disease progression, real-time polymerase chain reaction (RT-PCR) testing may be followed by chest radiography (CXR) or chest computed tomography (CT) to further aid in diagnosis or excluding COVID-19 disease. SARS-CoV-2 has been shown not only to pathologically impact the pulmonary system, but also the cardiovascular, gastrointestinal, and neurological systems to name a few...

SIGNIFICANCE: Conventional ultrasound-guided vascular access procedures are challenging due to the need for anatomical understanding, precise needle manipulation, and hand-eye coordination. Recently, augmented reality (AR)-based guidance has emerged as an aid to improve procedural efficiency and potential outcomes. However, its application in pediatric vascular access has not been comprehensively evaluated. AIM: We developed an AR ultrasound application, HoloUS, using the Microsoft HoloLens 2 to display live ultrasound images directly in the proceduralist's field of view...

Point-of-care ultrasound (POCUS) is an essential skill in various specialties like anesthesiology, critical care, and emergency medicine. Anesthesiologists utilize POCUS for quick diagnosis and procedural guidance in perioperative and critical care settings. Key applications include vascular ultrasound for challenging venous and arterial catheter placements, gastric ultrasound for aspiration risk assessment, airway ultrasound, diaphragm ultrasound, and lung ultrasound for respiratory assessment. Additional utilities of POCUS can include multi-organ POCUS evaluation for undifferentiated shock or cardiac arrest, ultrasound-guided central neuraxial and peripheral nerve blocks, focused cardiac ultrasound, and novel applications such as venous excess ultrasound...

Non-obstructive hypertrophic cardiomyopathy, or apical hypertrophic cardiomyopathy (ApHCM), also referred to as Yamaguchi syndrome, is a type of hypertrophic cardiomyopathy (HCM) characterized by significant thickening of the left ventricular apex without blockage in the left ventricular outflow tract. It is a very rare variant of HCM. Patients with non-obstructive HCM often experience symptoms such as chest pain, palpitations, shortness of breath, and syncope, which may resemble those seen in various cardiovascular and non-cardiac conditions...

INTRODUCTION: B-lines on lung ultrasound have been found in asymptomatic competitive breath-hold divers, but their significance and time to resolution are not well understood. We sought to investigate the relationship between B-lines, oxygen saturation, and respiratory symptoms after competitive dives to diagnose pulmonary injury. METHODS: We performed lung ultrasounds before (predive), immediately after (postdive), and within 1 h (follow-up) of a competitive dive...

(1) Background: Ocular emergencies account for 1.5-3% of emergency department (ED) visits and require urgent diagnosis to prevent serious complications. Ultrasonography is a crucial, non-invasive diagnostic tool for these conditions but traditionally lacks portability and integration with modern electronic smart devices. The purpose of this study was to assess the accuracy and performance of a new handheld ultrasound device in comparison to a conventional cart-based sonographic machine in patients attending to the ED for vitreo-retinal diseases...

BACKGROUND: The HHUS market is very complex due to a multitude of equipment variants and several different device manufacturers. Only a few studies have compared different HHUS devices under clinical conditions. We conducted a comprehensive prospective observer study with a direct comparison of nine different HHUS devices in terms of B-scan quality, device handling, and software features under abdominal imaging conditions. METHODS: Nine different HHUS devices (Butterfly iQ+, Clarius C3HD3, D5CL Microvue, Philips Lumify, SonoEye Chison, SonoSite iViz, Mindray TE Air, GE Vscan Air, and Youkey Q7) were used in a prospective setting by a total of 12 experienced examiners on the same subjects in each case and then assessed using a detailed questionnaire regarding B-scan quality, handling, and usability of the software...

INTRODUCTION: Heart failure (HF) is associated with significant morbidity, mortality, and health care costs. Stage B HF is defined as structural heart disease prior to developing symptomatic HF. If identified early in the disease process, preventative measures may be implemented to slow disease progression to Stage C (symptomatic) or Stage D (refractory) HF. Previous research has focused on outpatient screening for HF in the primary care setting; however, there are limited data on Stage B HF screening in the Emergency Department (ED) setting...

BACKGROUND: Minimally invasive thoracic surgical techniques require effective lung isolation using one-lung ventilation (OLV). Verification of lung isolation may be confirmed by auscultation, visual confirmation using fiberoptic bronchoscopy (FOB), or more recently, point-of-care ultrasound (POCUS). The aim of this study was to prospectively compare lung ultrasound with clinical auscultation to confirm OLV before thoracic surgery in pediatric patients. METHODS: This prospectively blinded feasibility study included 40 patients ranging in age from 0 to 20 years...

Over the past few years, point-of-care ultrasound (POCUS) has emerged as a critical diagnostic tool in emergency medicine, providing real-time imaging at the bedside.

We aimed to explore variability within the diagnostic and treatment pathways of ileocolic intussusception. A narrative review of the literature was conducted for peer-reviewed articles published in English between 2004 and 2024...

BACKGROUND: Point-of-care ultrasound (POCUS) is a valuable adjunct to traditional imaging and physical exam. Adult-Gerontology Acute Care Nurse Practitioners (AGACNPs) serve as primary providers for acutely ill patients across the country, yet there is limited literature to describe the AGACNP experience with POCUS training and clinical application. PURPOSE: This integrative review was to describe barriers to learning and performing POCUS that AGACNP's experience, identify necessary components of a successful POCUS curriculum, and synthesize evidence to propose solutions...

Budd-Chiari syndrome (BCS) is a life-threatening disease characterized by the partial or complete obstruction of hepatic venous outflow anywhere from the liver to the heart. In China, secondary BCS is rare. We present a case of secondary BCS caused by compression of the suprahepatic inferior vena cava (IVC), mainly due to local bile accumulation in the caudate lobe of the liver. This case highlights the scarcity of secondary BCS worldwide and the importance of point-of-care ultrasound (POCUS) in the diagnosis and treatment, especially in critical and comatose patients...

Background Ultrasound-guided peripheral intravenous (USGPIV) placement is more successful, comfortable, and longer lasting than traditional landmark-based IVs. While many hospitals have protocols for becoming credentialed in this skill, there is little information available about the USGPIV success rate during and after training. Objectives This pilot study aimed to quantify USGPIV attempts by emergency nurses undergoing USGPIV training and to determine if 10 successful USGPIVs predicted success in the next USGPIV...
