INTRODUCTION: The focused assessment with sonography in trauma (FAST) exam is a critical diagnostic test for intraperitoneal free fluid (FF). Current teaching is that fluid accumulates first in Morison's pouch. The goal of this study was to evaluate the "sub-quadrants" of traditional FAST views to determine the most sensitive areas for FF accumulation. METHODS: We analyzed a retrospective cohort of all adult trauma patients who had a recorded FAST exam by emergency physicians at a Level I trauma center from January 2012 - June 2013...

Thoracic ultrasound is used at the bedside in emergency and critical care settings. Advantages of ultrasound include rapid real-time, low-cost, diagnostic information that can direct patient care without the use of ionizing radiation. We describe methods on how to perform lung ultrasound, with the intent to educate the radiologist who might otherwise be relatively unfamiliar with thoracic sonography. We describe and depict the normal sonographic appearance of lung anatomy. We also show the sonographic appearance of a wide range of lung and pleural pathologies such as pneumonia, pneumothorax, as well as lung and pleural masses...

BACKGROUND: Esophageal foreign body (EFB) and impaction are common gastrointestinal emergencies. Detection with standard imaging can be challenging. Computed tomography is a commonly used non-invasive imaging modality, but is not 100% sensitive and not always feasible. Sensitivity of plain film x-ray varies widely and the addition of a barium swallow can obscure evaluation by subsequent esophagogastroduodenoscopy (EGD). Use of emergency ultrasound (EUS) for detection of EFB in adults has not been previously studied...

OBJECTIVES: Ultrasound (US) is vital to modern emergency medicine (EM). Across residencies, there is marked variability in US training. The "goal-directed focused US" part of the Milestones Project states that trainees must correctly acquire and interpret images to achieve a level 3 milestone. Standardized methods by which programs teach these skills have not been established. Our goal was to determine whether residents could achieve level 3 with or without a dedicated US rotation. METHODS: Thirty-three first- and second-year residents were assigned to control (no rotation) and intervention (US rotation) groups...

Targeted temperature management (TTM) improves survival and neurological outcome after nontraumatic cardiac arrest. However, TTM is not used widely after traumatic cardiac arrest because of concerns that it might exacerbate bleeding. We report the use of postarrest TTM after repair of blunt myocardial rupture. A 48-year-old man was admitted after being rescued from a major traffic accident by the local emergency service. Focused sonography showed pericardial fluid without cardiac tamponade. Computed tomography showed a large hematoma in the anterior mediastinum associated with hemopericardium...

Point-of-care (POC) ultrasonography is considered fundamental in emergency medicine training and recently has become a milestone in critical care fellowship programs as well. Currently, there is no such standard requirement for internal medicine residency programs in the United States. We present a new case and briefly review another case at our institution - a community hospital - in which internal medicine house staff trained in ultrasonography were able to uncover unexpected and critical diagnoses that significantly changed patient care and outcomes...

Yufeng Zhou, Xiaobin Wilson Gao
High-intensity focused ultrasound (HIFU) is emerging as an effective therapeutic modality in clinics. Besides the thermal ablation, tissue disintegration is also possible because of the interaction between the distorted HIFU bursts and either bubble cloud or boiling bubble. Hydrodynamic cavitation is another type of cavitation and has been employed widely in industry, but its role in mechanical erosion to tissue is not clearly known. In this study, the bubble dynamics immediately after the termination of HIFU exposure in the transparent gel phantom was captured by high-speed photography, from which the bubble displacement towards the transducer and the changes of bubble size was quantitatively determined...

Toru Kameda, Nobuyuki Taniguchi
Point-of-care abdominal ultrasound (US), which is performed by clinicians at bedside, is increasingly being used to evaluate clinical manifestations, to facilitate accurate diagnoses, and to assist procedures in emergency and critical care. Methods for the assessment of acute abdominal pain with point-of-care US must be developed according to accumulated evidence in each abdominal region. To detect hemoperitoneum, the methodology of a focused assessment with sonography for a trauma examination may also be an option in non-trauma patients...

Ultrasound is becoming an increasingly accessible modality for its easy and accurate evaluation of shoulder pathology. In Part 1 of our series (Am J Orthop. 2016;45(3):176-182), we showed how musculoskeletal ultrasound can be properly coded and reimbursed and can be as effective in evaluating the shoulder as magnetic resonance imaging, yet more economical. With more physicians beginning to incorporate this technology into their practice, we describe the physics of ultrasound and our methods for evaluating the shoulder with ultrasound...
