Calcium balance during hemodialysis

Semin Dial. Jan-Feb 2008;21(1):38-42. doi: 10.1111/j.1525-139X.2007.00368.x.


Calcium balance during hemodialysis (HD) is important in determining short-term cardiovascular function, this influences the hemodynamic tolerability of dialysis. In the longer term, calcium flux during HD is an important determinant of overall calcium balance in a patient and may also influence the development and progression of vascular calcification, with its attendant consequences. This article aims to review the assessment and mechanisms of calcium flux during HD, choice of dialysate calcium concentration, influence of HD modality, and potential consequences of therapy choices (cardiovascular and skeletal) resulting from an inappropriate intradialytic calcium balance.
