Immediate Diagnosis of Pyloric Stenosis with POCUS
A case of hypertrophic pyloric stenosis diagnosed immediately at the bedside by an emergency physicians (EP) using point-of-care ultrasound is presented. hypertrophic pyloric stenosis (HPS) is an important diagnosis for... read more
Clinically Significant Pleural Effusion in ICU
Clinically significant pleural effusion (PLEFF)—defined by a depth greater than or equal to 2 cm in a drainable location on thoracic ultrasound together with a potential adverse effect on patient progress—was detected... read more
Expiratory Muscle Dysfunction in Critically Ill Patients
The expiratory muscles are the "neglected component" of the respiratory muscle pump. Rather as the heart does not comprise only a left ventricle, but also a right one, the respiratory muscle pump is much more than just the... read more
Influence of Head-of-bed Elevation on the Measurement of IVC Diameter and Collapsibility
In a population of critically ill patients undergoing goal-directed ultrasound examinations, elevating head-of-bed (HOB) to 30° did not significantly alter inferior vena cava (IVC) measurements or CI. At 45°, however,... read more
A CT Scanner in Your Pocket? Lung Ultrasonography Beats Chest Radiography
Lung ultrasound is still a relatively young diagnostic modality, but it is evolving and growing at a rapid pace. Harrison's manual of internal medicine deemed to it to be a "useless" modality as recently as 2001. Once... read more
Neonatal Lung Ultrasonography
This book presents lung ultrasound as an accurate, reliable, low-cost and simple imaging technique, which poses no risk of radiation damage, making bedside use both feasible and convenient in neonatal wards. The aim of... read more
Diagnostic Accuracy of Point-of-Care Lung Ultrasonography and Chest Radiography in Adults With Symptoms Suggestive of ADHF
Standard tools used to diagnose pulmonary edema in acute decompensated heart failure (ADHF), including chest radiography (CXR), lack adequate sensitivity, which may delay appropriate diagnosis and treatment. Point-of-care... read more
Ultrasound-based Clinical Profiles for Predicting the Risk of Intradialytic Hypotension in Critically Ill Patients on Intermittent Dialysis
In critically ill patients on intermittent hemodialysis, the absence of hypervolemia as assessed by lung and vena cava ultrasound predisposes to intradialytic hypotension and suggests alternative techniques of hemodialysis... read more
Ultrasound Assessment of Gastric Volume in Critically Ill Patients
Ultrasonographic measurement of antral CSA is feasible and reliable in the majority of critically ill patients. This technique could be useful to manage critically ill patients at risk of aspiration or with enteral feeding. Antral... read more
Idiopathic Intracranial Hypertension
A 22 year-old female with a medical history of migraines and obesity who presents to the Emergency Department with a headache. Her headache was gradual in onset, but has progressively worsened and has not been relieved... read more
POCUS Is Not a Magic Bullet
A man in his 50s checked into our ED recently feeling weak, nauseated, and short of breath for two days. He had no significant medical history, and had previously been active and healthy. A fingerstick glucose at triage... read more
Diagnosis of Nonventilated Hospital-acquired Pneumonia
Nonventilated hospital-acquired pneumonia (NV-HAP) poses several barriers for diagnosis compared with VAP, and the available knowledge is limited. A call for further research in diagnosis of nonventilated HAP is urgent.... read more
Clinical Assessment of Critically Ill Patients by Whole-body Ultrasonography
Critical care ultrasonography (CCUS) is increasingly advocated and used, and is defined as point-of-care image acquisition, interpretation and clinical application, all performed by the critical care clinician, and directed... read more
Ultrasound for Lung Monitoring of Ventilated Patients
In the intensive care unit, patient lung ultrasound provides accurate information on lung morphology with diagnostic and therapeutic relevance. It enables clinicians easy, rapid, and reliable evaluation of lung aeration and... read more
Top 10 Perioperative Applications of Point-of-Care Ultrasound for Anesthesiologists
Anesthesiologists have been leaders in the use of point-of-care (POC) ultrasound for intraoperative transesophageal echocardiography (TEE), and to guide vascular access and regional anesthesia procedures. Recently, anesthesiologists... read more
Catheter Type in Pulmonary Embolism Intervention
Catheter based interventions for pulmonary embolism is on the rise. The rise in mainly in patients who present with submassive PE. The intent of intervention is to reduce clot burden. This is done to improve acute symptoms... read more
What is the lowest change in cardiac output that transthoracic echocardiography can detect?
In critically ill patients, changes in the velocity-time integral (VTI) of the left ventricular outflow tract, measured by transthoracic echocardiography (TTE), are often used to non-invasively assess the response to fluid... read more
Pathophysiology, echocardiographic evaluation, biomarker findings, and prognostic implications of septic cardiomyopathy
As a result of conflicting data, echocardiographic measures of left ventricular (systolic or diastolic) or right ventricular function cannot currently provide reliable prognostic information in patients with sepsis. Natriuretic... read more
The Importance of Skeletal Muscle Ultrasound in Critical Care
With growing interest in understanding muscle atrophy and function in critically ill patients and survivors, ultrasound is emerging as a potentially powerful tool for skeletal muscle quantification. However, there are key... read more
Extravascular Lung Water as a Target for Intensive Care
Extravascular lung water (EVLW) remains a useful guide for monitoring pulmonary edema (PO) and vascular permeability in sepsis, acute respiratory distress syndrome (ARDS), and heart failure. In addition, EVLW has a prognostic... read more
Time to Add a Fifth Pillar to Bedside Physical Examination
Inspection, palpation, percussion, and auscultation have been the 4 pillars of clinical bedside medicine. Although these basic methods of physical examination have served us well, traditional bedside examination, for a number... read more
Ultrasound-guided Pleural Effusion Drainage With a Small Catheter Using the Single-step Trocar or Modified Seldinger Technique
Ultrasound-guided pleural effusion drainage by catheter insertion is a safe and effective procedure. The success rate is low when the effusion is loculated and septated. Both the trocar and the modified Seldinger techniques... read more
