Have there been any GranuFlo- or NaturaLyte-related deaths?

There are no documented deaths attributed to the administration of NaturaLyte or GranuFlo during dialysis. However, an internal Fresenius Medical Care North America (FMC) memo uncovered and reported by RenalWEB, a website devoted to dialysis, says 941 patients suffered cardiac arrest inside Fresenius clinics in 2010. Sudden cardiac arrest is the leading cause of death for dialysis patients, according to RenalWEB.
