Improved Hemodynamic Tolerance of Intermittent Hemodialysis Sessions in Intensive Care Unite Using Citrate- vs Acetate-based Dialysate
- Conditions
- Intradialytic Hypotension

- Brief Summary
During intermittent hemodialysis (IHD), the occurrence of intradialytic hemodynamic instability (IHI) is frequent in ICU and impacted morbidity and mortality. Bicarbonate dialysate buffer improves hemodynamic tolerance compared to acetate dialysate buffer. However, bicarbonate dialysate buffer still contains a lower concentration of acetate, which could contribute to hemodynamic instability. Recently, citrate-based dialysate in bicarbonate hemodialysis instead of acetate have been proposed. They have the appropriate authorizations for routine use. The aim of this study is to compare acetate- vs citrate-based dialysate in terms of hemodynamic tolerance and effectiveness.
