BACKGROUND: Inferior vena cava (IVC) ultrasonography has been used for the diagnosis and prognosis of acute heart failure (HF). Its usefulness in chronic HF is less known. HYPOTHESIS: IVC ultrasonography is a useful tool in the care of patients with chronic HF. METHODS: For this prospective cohort study, 95 patients with chronic HF were included consecutively as they attended scheduled medical visits. Ultrasound was done with a 5-MHz convex probe device, calculating IVC collapse index (IVCCI)...

BACKGROUND: Diagnosis and management of patients presenting with acute dyspnea is one of the major challenges for physicians in emergency department (ED). A correct diagnosis is frequently delayed and difficult to ascertain, and clinical uncertainty is common, explaining the need for rapid diagnosis and a management plan. The primary aim of our study is to assess a diagnostic strategy using multiorgan point of care ultrasonography (USG) to differentiate patients presenting with acute dyspnea to ED into different diagnostic categories for timely management in a resource-limited setting...

Objective Shock is a common emergency condition with high morbidity and mortality, and judicious fluid resuscitation can significantly affect outcomes. The use of a bedside echocardiogram and evaluation of the inferior vena cava (IVC) via ultrasound (US) for collapsibility can predict volume status. Additionally, the Association of American Medical Colleges (AAMC) Entrustable Professional Activities (EPA) 10 states that residents need to be able to address a patient with a critical illness, including hypotension, on Day 1 of residency...

There has been increasing use of a novel combined femoral venous sheath, catheter and retrievable self-expanding and collapsible diamond-shaped IVC filter (Angel® Catheter, BiO2 Medical), in severely injured patients who cannot receive anticoagulation. As the filter is not detached from the catheter/sheath, it should be easily retrieved. Outcomes included in large registries demonstrate a high safety profile and a 100% retrieval rate. However, at our institution-a Level 1 major UK trauma centre with 4 years of substantial experience in using this device-we've encountered three cases of device fracture and subsequent complicated retrieval dating from Dec 2016 to March 2017...

PURPOSE: We aim to determine whether the combination of regional tissue oxygen saturation (StO2 ) measurement using near-infrared spectroscopy (NIRS), inferior vena cava (IVC) collapsibility and ejection fraction (EF) is able to detect occult sepsis. METHODS: We included adult patients in the emergency department with at least one of the following: fever; any one component of the quick sepsis-related organ function assessment (SOFA) score; heart rate≥100 beats per minute; or white cell count <4...

PURPOSE: To explore the relationship between the shape of the inferior vena cava (IVC) lumen and central venous pressure (CVP). METHODS: In 60 patients undergoing mechanical ventilation and CVP monitoring in the Intensive Care Unit of Peking Union Medical College Hospital from July to October 2016, we measured with B-mode ultrasonography the transverse maximum (MXD) and minimum diameter (MID) of the IVC at end expiration, and calculated the diameter ratio (DR) as MXD/MID...

INTRODUCTION: Ultrasound assessment of the inferior vena cava (IVC) has gained favour in aiding fluid management decisions for controlled, mechanically ventilated patients as well as in non-mechanically ventilated, spontaneously breathing patients. Its utility in spontaneously breathing patients during positive pressure non-invasive ventilation has not yet been determined. The use of the axillary vein, as an alternative option to the IVC due to its ease of accessibility and independence from intra-abdominal pressure, has also not been evaluated...

OBJECTIVE: The intent of fluid bolus therapy (FBT) is to increase cardiac output and tissue perfusion, yet only 50% of septic children are fluid responsive. We evaluated respiratory variation of inferior vena cava (IVC) diameter as a predictor of fluid responsiveness. METHODS: A prospective observational study in the ED of The Royal Children's Hospital, Melbourne, Australia. Patients were spontaneously ventilating children treated with FBT for sepsis-induced acute circulatory failure...

Inferior vena cava (IVC) filters have been used for over five decades as an alternative to anticoagulation therapy in the treatment of venous thromboembolic disease. However, complications associated with IVC filters remain common. Though many studies have investigated blood flow in the IVC, the effects of respiration-induced IVC collapse have not been evaluated. Our hypothesis is that IVC collapse may have an influence on IVC filter performance. Therefore, we herein investigate the hemodynamics in uncollapsed and collapsed IVC configurations using in vitro flow experiments and computational simulations...

BACKGROUND: The optimal strategy of fluid administration during spinal anesthesia for cesarean delivery is still unclear. Ultrasonography of the inferior vena cava (IVC) has been recently used to assess the volume status and predict fluid responsiveness. In this double-blind, randomized controlled study, we compared maternal hemodynamics using a combination of 500-mL colloid preload and 500-mL crystalloid coload versus 1000-mL crystalloid coload. We assessed the IVC at baseline and at subsequent time points after spinal anesthesia...

Acute decompensated heart failure (ADHF) is a common reason for admission to the hospital, and readmission is frequent. Multiple factors contribute to rehospitalizations, but inadequate assessment of volume status leading to persistent congestion is an important factor. We sought to determine if focused cardiac ultrasound (FCU) of the inferior vena cava (IVC), as a surrogate of volume status, would predict readmission of ADHF patients after index hospitalization. Patients admitted with a primary diagnosis of ADHF were prospectively enrolled...

BACKGROUND: Significant hypotension is frequent after spinal anaesthesia and fluid administration as therapy is usually empirical. Inferior vena cava (IVC) ultrasound (US) is effective to assess fluid responsiveness in critical care patients. The aim of this study was to evaluate the IVCUS-guided volume optimization to prevent post-spinal hypotension. METHODS: In this prospective, randomized, cohort study, 160 patients scheduled for surgery under spinal anaesthesia were randomized into a study group (IVCUS-group), consisting of an IVCUS analysis before spinal anaesthesia with IVCUS-guided volume management and a control group (group C) with no IVCUS assessment...

INTRODUCTION: Retrospective data indicates that dehydration in acute ischemic stroke patients may be common, even though these patients frequently have elevated blood pressure. We sought to evaluate clinical and laboratory measures of intravascular volume status compared to more objective measures using ultrasound measurements of the inferior vena cava (IVC). METHODS: This was a prospective observation study of acute ischemic stroke patients in the emergency department...

Afferent fibers expressing the vanilloid receptor 1 (VR1) channel are implicated in cardiac nociception, however, their role in modulating reflex responses to cardiac stress is not well-understood. We evaluated this role in Yorkshire pigs by percutaneous epicardial application of resiniferatoxin (RTX), a toxic activator of the VR1 channel, resulting in depletion of cardiac VR1-expressing afferents. Hemodynamics, epicardial activation recovery intervals (ARIs), and in vivo activity of stellate ganglion (SG) neurons (SGNs) were recorded in control and RTX-treated animals...

OBJECTIVE: Fluid responsiveness is the ability to increase the cardiac output in response to a fluid challenge. Only about 50% of patients receiving fluid resuscitation for acute circulatory failure increase their stroke volume, but the other 50% may worsen their outcome. Therefore, predicting fluid responsiveness is needed. In this purpose, in recent years, the assessment of the inferior vena cava (IVC) through ultrasound (US) has become very popular. The aim of our work was to systematically review all the previously published studies assessing the accuracy of the diameter of IVC or its respiratory variations measured through US in predicting fluid responsiveness...

INTRODUCTION: Ultrasound is an emerging method for assessing lung congestion but is still seldom used. Lung congestion is an important risk of cardiac events and death in end-stage renal disease (ESRD) patients on hemodialysis (HD). OBJECTIVE: We investigated possible variables associated with lung congestion among diabetics with ESRD on HD, using chest ultrasound to detect extracellular lung water. METHODS: We studied 73 patients with diabetes as the primary cause of ESRD, undergoing regular HD...

BACKGROUND: Evaluation of patient's dry weight remains challenging in chronic hemodialysis (HD) especially in children. Inferior Vena Cava (IVC) measurement was reported useful to assess fluid overload both in adults and children. METHODS: We performed a monocentric prospective study to evaluate the relation between predialytic IVC diameter measurements and hydration status evaluated by physicians and bioimpedance spectroscopy (BIS) and between IVC measurements and persistent hypertension...

Early stage acute kidney injury (AKI) is an independent risk factor for an increase in mortality. Accurate assessment of volume status is a major challenge during the early stages of acute renal injury. Determining volume status based on the history and physical exam lacks accuracy. Urine sodium and free excretion of sodium (FENa) provide objective evidence of intravascular volume status when interpreted carefully and is helpful to delineate prerenal from intrinsic renal failure. In recent years point of care ultrasound has been used to assess volume status...

PURPOSE: To investigate correlation of central venous pressure (CVP) with ultrasonographic measurement of central veins, along with association between these variables and occurrence of intradialytic adverse events in hospitalized patients. MATERIALS AND METHODS: Patients requiring hemodialysis via dialysis catheter were prospectively enrolled. CVP measurements through catheter, internal jugular vein aspect ratio, subclavian vein collapsibility, inferior vena cava (IVC) maximal diameter, and IVC collapsibility were recorded before and after hemodialysis...

BACKGROUND: The collapsibility index of the inferior vena cava is traditionally visualized from the subcostal region in the sagittal plane, referred to here as cIVCSS . Alternatively, the collapsibility index of the inferior vena cava can be visualized from the right midaxillary line in the coronal plane, referred to here as cIVCRC . It is unclear whether values of cIVCRC are comparable with values of cIVCSS because the inferior vena cava collapses asymmetrically into an elliptical form, quantified as the flat ratio of the inferior vena cava (F-IVC)...
