Trial of Dialysate Sodium in Chronic Hospitalized Hemodialysis Patients

Intra-dialytic Hypotension Clinical Trial

Official title: Randomized Trial of Dialysate Sodium in Chronic Hospitalized Hemodialysis Patients

Status Completed

Clinical Trial Summary

Intra-dialytic hypotensive (IDH) events can be defined as an abrupt decline in blood pressure that cause symptoms and/or require an intervention. They are common, affecting up to one third of maintenance HD sessions. Detrimental associations include: development of myocardial stunning, cerebral hypo-perfusion, vascular access thrombosis and greater mortality. Rapid solute removal by HD generates temporary osmotic gradients between the intra-vascular and intra-cellular compartments, promoting trans-cellular fluid movement and resultant hypotension. Manipulation of osmotic gradients, e.g. using higher dialysate sodium (DNa), may ameliorate excess SBP decline during HD. This study aims to assess the effects of higher (142 mmol/L) versus lower (138 mmol/L) dialysate sodium (DNa) use in adult chronic hemodialysis patients admitted to hospital on intra-dialytic blood pressure and biomarkers of cardiac ischemia. The investigators will randomly assign subjects to higher versus lower DNa during their hospital stay, up to a maximum of six HD sessions.
