Key result
Dialysis machines set to deliver a sodium concentration of 136 mmol/l actually delivered a higher concentration of 141.8±2.9 mmol/l by flame photometry and 142.5±2.4 mmol/l by ISE.

Absolute Event Rate: 141.8% vs 136%
Dialysis machines set to deliver hyponatraemic dialysate actually deliver higher sodium concentrations than set, highlighting the need to measure delivered concentrations in clinical trials.

Dialysis sodium delivery exceeds programmed values; leaves open accuracy of hyponatremic dialysate effects in prior trials.
Ekbal et al. (2016) conducted an observational in Hemodialysis (n=16). Hemodialysis machines set to 136 mmol/l sodium vs. Set dialysate sodium concentration was evaluated on Delivered dialysate sodium concentration. Dialysis machines set to deliver a sodium concentration of 136 mmol/l actually delivered a higher concentration of 141.8±2.9 mmol/l by flame photometry and 142.5±2.4 mmol/l by ISE.
