Ultrasound Detection of Patellar Fracture and Evaluation of the Knee Extensor Mechanism in the Emergency Department.

Traumatic injuries to the knee are common in emergency medicine. Bedside ultrasound (US) has benefits in the rapid initial detection of injuries to the patella. In addition, US can also quickly detect injuries to the entire knee extensor mechanism, including the quadriceps tendon and inferior patellar ligament, which may be difficult to diagnose with plain radiographs.

Point-of-Care Ultrasound for the Detection of Traumatic Intracranial Hemorrhage in Infants: A Pilot Study.

Objectives: Computed tomography is the criterion standard imaging modality to detect intracranial hemorrhage (ICH) in children and infants after closed head injury, but its use can be limited by patient instability, need for sedation, and risk of ionizing radiation exposure. Cranial ultrasound is used routinely to detect intraventricular hemorrhage in neonates. We sought to determine if point-of-care (POC) cranial ultrasound performed by emergency physicians can detect traumatic ICH in infants.

The diagnosis of right heart thrombus by focused cardiac ultrasound in a critically ill patient in compensated shock.

Right heart thrombus (RHT) is a life-threatening diagnosis that is rarely made in the emergency department (ED), but with the increasing use of focused cardiac ultrasound (FocUS), more of these cases may be identified in a timely fashion. We present a case of an ill-appearing patient who had an immediate change in management due to the visualization of RHT soon after arrival to the ED. The diagnosis was confirmed after a cardiology-performed ultrasound (US).

Spontaneous pneumomediastinum on bedside ultrasound: case report and review of the literature.

Spontaneous pneumomediastinum is a rare disease process with no clear etiology, although it is thought to be related to changes in intrathoracic pressure causing chest pain and dyspnea. We present a case of a 17-year-old male with acute chest pain evaluated initially by bedside ultrasound, which showed normal lung sliding but poor visualization of the parasternal and apical cardiac views due to significant air artifact, representing air in the thoracic cavity. The diagnosis was later verified by chest radiograph.

Point-of-care ultrasound in diagnosing pyomyositis: a report of three cases.

Background: Pyomyositis is a bacterial infection of skeletal muscle that often results in deep intramuscular abscesses. The absence of external dermatologic manifestations in the early stages of pyomyositis makes this a challenging diagnosis. In addition, physical examination findings can be difficult to distinguish from more common processes, such as soft-tissue cellulitis.

The FAST and E-FAST in 2013: trauma ultrasonography: overview, practical techniques, controversies, and new frontiers.

This article reviews important literature on the FAST and E-FAST examinations in adults. It also reviews key pitfalls, limitations, and controversies. A practical "how-to" guide is presented.

Thoracic ultrasonography.

Thoracic ultrasonography (US) has proved to be a valuable tool in the evaluation of the patient with shortness of breath, chest pain, hypoxia, or after chest trauma. Its sensitivity and specificity for detecting disease is higher than that of a chest radiograph, and it can expedite the diagnosis for many emergent conditions. This article describes the technique of each thoracic US application, illustrating both normal and abnormal findings, as well as discussing the literature.

Cardiac echocardiography.

Focused cardiac echocardiography has become a critical diagnostic tool for the emergency physician and critical care physician caring for patients in shock and following trauma to the chest, and those presenting with chest pain and shortness of breath,. Cardiac echocardiography allows for immediate diagnosis of pericardial effusions and cardiac tamponade, evaluation of cardiac contractility and volume status, and detection of right ventricular strain possibly seen with a significant pulmonary embolus. This article addresses how to perform cardiac echocardiography using the standard windows, how to interpret a focused goal-directed examination, and how to apply this information clinically at the bedside.

Bedside ultrasound in a case of blunt scrotal trauma.

This case study describes a patient who suffered blunt force trauma to the scrotum. Use of bedside emergency ultrasound facilitated early diagnosis of a ruptured testicle and allowed for prompt urological consultation and timely surgical repair. The utility of bedside emergency ultrasound in the evaluation of testicular trauma, as well as the outcome of our case, is discussed here.

Ultrasound detection of a renal mass in a patient with flank pain and hematuria.

Flank pain with hematuria is a common chief complaint in the emergency department (ED). Patients are often diagnosed with renal calculi or pyelonephritis and discharged with analgesics or antibiotics and follow-up. This case study describes a patient who presented to the ED with a 1 week history of flank pain and hematuria and was subsequently found to have a large renal mass on bedside ultrasound.

Emergency department diagnosis of infective endocarditis using bedside emergency ultrasound.

Infective endocarditis is a challenging diagnosis that is rarely made in the emergency department. As the use of focused emergency ultrasound expands into more applications, including advanced echocardiography, the diagnosis of infective endocarditis may be made earlier, potentially leading to more timely treatment. We report a case of an ill-appearing patient presenting to the emergency department with an indwelling central venous catheter, a cardiac murmur, and necrotic toes, who was diagnosed with a large tricuspid vegetation and prominent tricuspid regurgitation on bedside emergency ultrasound.

Transjugular Intrahepatic Portosystemic Shunt (TIPS) Migration to the Heart Diagnosed by Emergency Department Ultrasound.

A 57-year-old man presented to our emergency department with altered mental status. He had a past medical history significant for cirrhosis and previous placement of a transjugular intrahepatic portosystemic shunt (TIPS). On cardiac auscultation, a new heart murmur and an unexpected degree of cardiac ectopy were noted.

Intramedullary spinal neurocysticercosis presenting as brown-sequard syndrome.

Cysticercosis is an emerging disease in the United States. Neurocysticercosis may rarely cause disease within the spinal cord, but the occurrence of such pathology can produce debilitating symptoms for patients. We present the second report in the literature of intramedullary spinal neurocysticercosis presenting with a Brown-Sequard syndrome.

Bedside ultrasound in resuscitation and the rapid ultrasound in shock protocol.

Assessment of hemodynamic status in a shock state remains a challenging issue in Emergency Medicine and Critical Care. As the use of invasive hemodynamic monitoring declines, bedside-focused ultrasound has become a valuable tool in the evaluation and management of patients in shock. No longer a means to simply evaluate organ anatomy, ultrasound has expanded to become a rapid and noninvasive method for the assessment of patient physiology.

The role of bedside ultrasound in the diagnosis of pericardial effusion and cardiac tamponade.

This review article discusses two clinical cases of patients presenting to the emergency department with pericardial effusions. The role of bedside ultrasound in the detection of pericardial effusions is investigated, with special attention to the specific ultrasound features of cardiac tamponade. Through this review, clinicians caring for patients with pericardial effusions will learn to rapidly diagnose this condition directly at the bedside.
