BACKGROUND M-mode or "motion" mode is a form of ultrasound imaging that is of high clinical utility in the emergency department. It can be used in a variety of situations to evaluate motion and timing, and can document tissue movement in a still image when the recording of a video clip is not feasible. OBJECTIVES In this article we describe several(More)
AIM The purpose of this study was to compare lung ultrasound findings in both the supine and upright positions in heart failure patients presenting with dyspnea or chest pain. METHODS AND RESULTS We performed lung ultrasonography on 50 heart failure patients in the emergency department. Each subject underwent eight-zone lung sonography in the seated(More)
BACKGROUND Emergency physicians can utilize bedside ultrasound to aid in the diagnosis of abdominal wall hernias and in the reduction of incarcerated hernias. OBJECTIVES To review the sonographic appearance and diagnostic criteria of abdominal wall hernias and to describe the potential use of ultrasound as an aid in hernia reduction. CASE REPORT An(More)
BACKGROUND Some subcutaneous foreign bodies (FBs) are not easily visualized during physical examination and may not be detected on radiographic evaluation. Ultrasound (US) is capable of visualizing FBs of varying compositions. Previous studies have examined the use of US to detect FBs in deceased animal or human tissue. This study used live anesthetized(More)
The placement of a central venous catheter remains an important intervention in the care of critically ill patients in the emergency department. We propose an ultrasound-first protocol for 3 aspects of central venous catheter placement above the diaphragm: dynamic procedural guidance, evaluation for pneumothorax, and confirmation of the catheter tip(More)
We present 2 recent cases of heterotopic pregnancy in which bedside sonography performed by the treating emergency physician was used to identify the heterotopic pregnancy and facilitate prompt gynecologic intervention. The cases, the sonographic approach to the diagnosis of heterotopic pregnancy, and a review of the literature are presented.
BACKGROUND There is a well-established relationship between obesity, as measured by body mass index (BMI), and overall health risk. The presence of body fat is a known limitation to ultrasound, but it is unknown whether any decrease in quality due to obesity limits the interpretability of focused bedside echocardiography (FBE). OBJECTIVES To correlate(More)
BACKGROUND Emergency point-of-care ultrasound (POC u/s) is an example of a health information technology that improves patient care and time to correct diagnosis. POC u/s examinations should be documented, as they comprise an integral component of physician decision making. Incomplete documentation prevents coding, billing and physician group compensation(More)
