Determination of the hemodialysis ultrafiltration volume is guided by the clinician's estimate of dry weight. A poor estimate of this dry weight may result in insufficient fluid depletion causing a state of volume overload, which may be associated with long-term left ventricular failure, high blood pressure and excess of mortality. The diagnosis of fluid overload in haemodialysis patient is routinely based on clinical examination which consists of cardiopulmonary auscultation and edema palpation of limb member. Clinical examination can be completed by paraclinical examinations, and bioimpedance is an objective tool that assess fluid overload state. This test provides an individualized hydration status and fluid overload based on normal extracellular volume considering body composition. Echocardiography allows an accurate assessment of blood volume status by simultaneous studying left ventricular filling pressures, systolic pulmonary artery pressure and the diameter of the inferior vena cava. Lung ultrasound analyses the B-lines defined as artefactual images resulting from contact between air in "alveoli" and water in "septa". It can estimate pulmonary congestion. The aim of the study is to evaluate the lung ultrasound using "8 sites" score accuracy for estimating fluid overload of patients before hemodialysis session.
Centre Hospitalier Universitaire, Amiens is the lead sponsor of 576 studies on the registry; 178 are open to participants now.
Counted across the registry records on this site, refreshed daily.
Exclusion Criteria:
Subjects are enrolled during their usual session in the hemodialysis unit of the Amiens University Hospital. Before starting the hemodialysis, lung ultrasound according to the "8 sites" score and a measure of bioimpedance will be performed in dorsal decubitus. In a 2nd time, an echocardiography is realized. During haemodialysis session, biological analysis and clinical score will be assessed
number of patients with fluid overload
Fluid overloaded are determined by both tecniques : estimated fluid overload and lung ultrasound measured fluid overload
