OBJECTIVES: Bedside ultrasound is increasingly being used to guide fluid management in shocked patients. Little data exist on the inter-rater reliability of techniques used, especially when performed by nonexpert trainee doctors. The primary aim of this study is to measure the inter-rater reliability of five ultrasound techniques commonly used to guide fluid management: inferior vena cava collapsibility index (IVCCI), transthoracic echocardiography (TTE)-derived stroke volumes, ultrasound cardiac output monitor (USCOM) derived stroke volume and carotid artery blood flow and corrected flow time measurements...

PURPOSE: Lung ultrasound is an accurate and accessible tool to quantify lung edema. Furthermore, left ventricle filling pressures (LVFP) can be assessed with transthoracic echocardiography (TTE) by the E/e' ratio (E/e'). The present study aimed to assess the correlation between E/e' and lung edema quantified by a simplified lung ultrasound score (LUS) in newly admitted septic patients. MATERIALS AND METHODS: In this prospective observational cohort, septic adult patients admitted at the emergency department of a tertiary hospital were included...

Adequate assessment of fluid status is an imperative objective in the management of all types of patients in cardiology, intensive care, and especially nephrology. Fluid overload is one of the most common modifiable risk factors directly associated with hypertension, heart failure, left ventricular hypertrophy, and eventually, higher morbidity and mortality risk in these categories of patients. Different methods are commonly used to determine fluid status (eg, clinical assessment, natriuretic peptide concentrations, echocardiography, inferior vena cava measurements, or bioimpedance analysis)...

OBJECTIVES: Perturbed hemodynamic function complicates severe malaria. The Fluid Expansion as Supportive Therapy trial demonstrated that fluid resuscitation, involving children with severe malaria, was associated with increased mortality, primarily due to cardiovascular collapse, suggesting that myocardial dysfunction may have a role. The aim of this study was to characterize cardiac function in children with severe malaria. DESIGN: A prospective observational study with clinical, laboratory, and echocardiographic data collected at presentation (T0) and 24 hours (T1) in children with severe malaria...

Pericardial fluid is a common finding on echocardiography. Less than 10 mm of fluid on ultrasound scan is not necessarily associated with any significant illness. Clinical examination, blood count, renal and liver enzymes and thyroid function tests as well as inflammatory marker tests are often adequate for a patient who is in good health. A significant amount of fluid requires further investigations, especially in a symptomatic patient. Cancers, infections and various systemic diseases are the most common causes of prominent effusion...

BACKGROUND: Venoarterial extracorporeal membrane oxygenation (VA-ECMO) has been proved to effectively rescue patients from refractory cardiogenic shock. The role of the right ventricle in VA-ECMO has been emphasized, but quantitative right ventricular (RV) analysis in this population has been lacking. Three-dimensional echocardiography (3DE) is currently suggested for RV volumetric analysis. The aims of this study were to assess 3DE-derived RV ejection fraction (RVEF) in patients with refractory cardiogenic shock stabilized by VA-ECMO and to explore the association between 3DE-derived RVEF and weaning success as well as the prognosis after the first intent of decannulation...

BACKGROUND: Chronic heart failure (HF) is a relevant and growing public health problem. Although the prognosis has recently improved, it remains a lethal disease, with a mortality that equals or exceeds that of many malignancies. Furthermore, chronic HF is costly, representing a large and growing drain on healthcare resources. METHODS: This narrative review is based on the material searched for and obtained via PubMed up to May 2017. The search terms we used were: "heart failure, echocardiography, natriuretic peptides" in combination with "treatment, biomarkers, guidelines"...

BACKGROUND: Hemodynamic balance in the heart-brain axis is increasingly recognized as a crucial factor in maintaining functional and structural integrity of the brain and thereby cognitive functioning. Patients with heart failure (HF), carotid occlusive disease (COD), and vascular cognitive impairment (VCI) present themselves with complaints attributed to specific parts of the heart-brain axis, but hemodynamic changes often go beyond the part of the axis for which they primarily seek medical advice...

REVIEW
Yogen Singh
Hemodynamic instability and inadequate cardiac performance are common in critically ill children. The clinical assessment of hemodynamic status is reliant upon physical examination supported by the clinical signs such as heart rate, blood pressure, capillary refill time, and measurement of the urine output and serum lactate. Unfortunately, all of these parameters are surrogate markers of cardiovascular well-being and they provide limited direct information regarding the adequacy of blood flow and tissue perfusion...

BACKGROUND: Pleural effusion (PLE) may lead to low blood pressure and reduced cardiac output. Low blood pressure and reduced cardiac output are often treated with fluid loading and vasopressors. This study aimed to determine the impact of fluid loading and norepinephrine infusion on physiologic determinants of cardiac function obtained by ultrasonography during PLE. METHODS: In this randomised, blinded, controlled laboratory study, 30 piglets (21.9 ± 1.3 kg) had bilateral PLE (75 mL/kg) induced...

BACKGROUND: Continuous-wave Doppler (CWD) ultrasound through the left ventricular outflow tract is one modality used for non-invasive cardiac output measurement. The ultrasonic cardiac output monitor (USCOM) is a relatively new monitor which uses a small, transcutaneous ultrasound probe to measure cardiac output with CWD via the suprasternal window. It is faster and less complex to train new users than conventional echocardiography. In addition to stroke volume (SV), the USCOM can calculate stroke volume variation (SVV) and the Smith-Madigan inotropy index (SMII), which is an estimate of the pre-load independent contractility of the myocardium...

OBJECTIVES: First, we aimed at assessing whether fluid responsiveness is predicted by the effects of an end-expiratory occlusion on the velocity-time integral of the left ventricular outflow tract. Second, we investigated whether adding the effects of an end-inspiratory occlusion and of an end-expiratory occlusion on velocity-time integral can predict fluid responsiveness with similar reliability than end-expiratory occlusion alone but with a higher threshold, which might be more compatible with the precision of echocardiography...

REVIEW
Heike Rabe, Hector Rojas-Anaya
During the transition to extrauterine life, preterm infants are at high risk of developing circulatory failure. Currently, hypotension is used as major diagnostic criteria for starting treatments such as fluid boluses, inotropes or steroids. Most of these treatment options have not been studied in large randomised controlled trials for efficacy and safety and are under discussions. A wide variety in their use is reported in the literature and clear evidence about which inotrope or other treatment should be preferred is lacking...

BACKGROUND: Fluid management remains a major challenge of hemodialysis (HD) care, with serious implications for morbidity and mortality. Intradialytic fluid management is typically guided by blood pressure, an indirect resultant of hemodynamics status. Direct measurements of hemodynamic parameters may improve cardiovascular outcomes by providing rational bases for intervention. We compare stroke volume (SV) measurements using a noninvasive, regional biompedance cardiography device (NiCaS) with Doppler echocardiography (Echo) in HD setting...

OBJECTIVE: To evaluate early and dynamic changes of the left ventricular systolic function of patients with septic shock by two-dimensional speckle tracking imaging (2D-STI), and to provide guidance for treatment and prognosis. METHODS: Fifty-eight septic shock patients admitted to intensive care unit (ICU) of Subei People's Hospital from January 2016 to April 2017 were enrolled. The septic shock patients were given early fluid resuscitation. The left ventricular end-diastolic volume (LVEDV), left ventricular end-systolic volume (LVESV), left ventricular ejection fraction (LVEF), early diastolic mitral flow velocity/early diastolic mitral annular peak velocity (E/Em) were obtained by conventional echocardiography, and the left ventricular global longitudinal strain (GLS), global circumferential strain (GCS), global radial strain (GRS) were obtained by 2D-STI before fluid resuscitation and 1, 3, 7, 14 days after fluid resuscitation...
