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
Recommendations on the Use of Ultrasound Guidance for Adult Thoracentesis
The use of ultrasound guidance for thoracentesis has been associated with increased success rates and decreased complication rates. Ultrasound can be used to estimate the pleural fluid volume, characterize the effusion as... read more
Trick of the Trade: Bubble Study for Confirmation of Central Line Placement
The safe placement a central venous catheter (CVC) remains an important part of caring for critically ill patients. Over 5 million CVCs are placed each year in the United States. It is crucial to confirm that the central... read more
Ultrasound-Guided Peripheral Intravenous Access
Obtaining intravenous (IV) access is a basic necessity in the emergency department. So what do you do when you are unable to place a peripheral IV, and your go-to external jugular line is not an option? You certainly do not... read more
Bedside Ultrasound Assessment of Lung Reaeration in Patients With Blunt Thoracic Injury Receiving High-Flow Nasal Cannula Oxygen Therapy
High-flow nasal cannula oxygen therapy may be considered as an initial respiratory therapy for trauma patients with blunt chest injury. High-flow nasal cannula therapy could improve lung aeration as noted by the transthoracic... read more
Transient Systolic Anterior Motion with Junctional Rhythm After Mitral Valve Repair in the ICU
This case report shows that junctional rhythm can cause deterioration of SAM, LVOTO, and MR, and can lead to unstable hemodynamics in a patient with right ventricular failure after MVR. Atrial pacing can resolve SAM, LVOTO,... read more
Assessment of the adequacy of oxygen delivery
In this article, we review physiologic principles of global oxygen delivery, and discuss the bedside approach to assessing the adequacy of oxygen delivery in critically ill patients. Although there have been technological... read more
