Complications of hemodialysis treatments due to dialysate contamination and composition errors

Although hemodialysis is a routine outpatient treatment for millions of patients with a proven safety record, accidents and errors do occur from time to time. Many nephrologists are unaware of the technical aspects of providing a safe and reliable dialysate and rely on the support and advice of renal technologists. Complications may arise due to bacterial and chemical contamination of potable water, errors in dialysate acid or bicarbonate solution composition and proportioning, and resetting machine conductivity and temperature controls. As such, clinicians need to be aware of the possible complications of hemodialysis so that these are recognized promptly to provide appropriate management and minimize patient harm.
