A STUDY ON THE VARIATION IN SERUM ELECTROLYTE CONCENTRATION AFTER THE USE OF POLYETHYLENE GLYCOL CONTAINING ASCORBIC ACID AND ELECTROLYTES FOR ORAL WHOLE BOWEL IRRIGATION IN DIALYSIS PATIENTS

Abstract

Purpose : The variation in serum electrolyte concentration after the use of polyethylene glycol containing ascorbic acid and electrolytes (PEG-ASC) for bowel preparation in dialysis patients was examined. Method : Blood samples were obtained from dialysis patients before taking PEG-ASC and after colonoscopy. Results : In the group of patients not under hyperkalemia remedy (12 patients), there was a significant increase in the serum potassium concentration after taking PEG-ASC (4.5±0.4mEq/L vs. 4.9±0.7mEq/L, before vs. after taking PEG-ASC, P＝0.012). Conclusion : When dialysis patients undergo oral whole bowel irrigation with PEG-ASC, it is important to monitor their potassium concentration, and a potassium-lowering drug may need to be administered.
