BACKGROUND Measurement of the common bile duct (CBD) has traditionally been considered an integral part of gallbladder sonography, but accurate identification of the CBD can be difficult for novice sonographers. OBJECTIVE To determine the prevalence of isolated sonographic CBD dilation in emergency department (ED) patients with cholecystitis or(More)
BACKGROUND Intraosseous (IO) access can be complicated by obesity. Successful placement of a 25 mm IO needle is unlikely when soft tissue depth exceeds 20 mm. OBJECTIVES The authors examined the relationship between body mass index (BMI), the ability to palpate the tibial tuberosity (TT), and soft tissue depth at recommended IO insertion sites. METHODS(More)
BACKGROUND The effectiveness of point of care (POC) right upper quadrant ultrasound (RUQ US) in the diagnosis of biliary disease has been well studied. Extrabiliary pathology that might remain undetected in the course of typical, focused POC RUQ US has not been directly examined. OBJECTIVES Our objective was to determine the prevalence and clinical(More)
Cardiac arrest in the adolescent population secondary to congenital heart disease (CHD) is rare. Focused cardiac ultrasound (FoCUS) in the emergency department (ED) can yield important clinical information, aid in resuscitative efforts during cardiac arrest and is commonly integrated into the evaluation of patients with pulseless electrical activity (PEA).(More)
BACKGROUND As bedside ultrasound (BUS) is being increasingly taught and incorporated into emergency medicine practice, measurement of BUS competency is becoming more important. The commonly adopted experiential approach to BUS competency has never been validated on a large scale, and has some limitations by design. OBJECTIVE Our aim was to introduce and(More)
INTRODUCTION The goal of this study was to investigate the efficacy of diagnosing shoulder dislocation using a single-view, posterior approach point-of-care ultrasound (POCUS) performed by undergraduate research students, and to establish the range of measured distance that discriminates dislocated shoulder from normal. METHODS We enrolled a prospective,(More)
