[Electroencephalographic changes in children dialyzed according to various protocols]
Insights
Bicarbonate dialysis and high-sodium acetate dialysates may improve electroencephalographic (EEG) changes in children undergoing hemodialysis. Bicarbonate dialysis generally showed better clinical tolerance and EEG results compared to other methods.
Area of Science:
- Pediatric Nephrology
- Neurophysiology
Context:
- Hemodialysis is a critical treatment for children with kidney failure.
- Dialysis strategies can influence neurological function.
- Electroencephalography (EEG) monitors brain activity.
Purpose:
- To evaluate electroencephalographic (EEG) changes in children during four different hemodialysis strategies.
- To compare the effects of acetate vs. bicarbonate dialysates.
- To assess the impact of high-sodium dialysate and hemodiafiltration.
Summary:
- EEG alterations occurred during most hemodialysis sessions, except with bicarbonate dialysates.
- High-sodium acetate dialysates showed less pronounced EEG changes than standard acetate.
- No direct correlation was found between clinical symptoms and EEG changes.
Impact:
- Bicarbonate dialysis demonstrates better clinical tolerance and EEG stability in pediatric hemodialysis.
- Findings suggest optimizing dialysate composition can mitigate neurological side effects.
- This research informs strategies for improving patient comfort and outcomes during renal replacement therapy.
Abstract:
A study of electroencephalographic changes in six children during hemodialysis sessions was done in order to evaluate the effects of four different dialysis strategies: acetate or bicarbonate dialysates (sodium 142 mEq/1), acetate dialysate with high sodium concentration (148-150 mEq/1), and hemodiafiltration. There are basic activity alterations in all cases except during bicarbonate dialysis sessions. Alterations are, however, less pronounced during dialysis sessions with high sodium concentration dialysate. No strict concordance between clinical manifestations and electroencephalographic changes was observed. However, better tolerance of bicarbonate dialysis sessions is assessed with respect to clinical symptoms as well as electroencephalograms.
