Singh T, Alagasundaramoorthy S, Gregory A, et al. - By performing a retrospective analysis, researchers investigated whether low potassium dialysate 1 meq/L was related to higher mortality among hospitalized end stage renal disease (ESRD) patients with severe hyperkalemia (serum potassium > 6.5 mmol/L). This study involved 209 ESRD patients receiving hemodialysis admitted with severe hyperkalemia. Mean serum potassium was 7.1 mmol/L. Among ESRD patients with severe hyperkalemia, the in-hospital mortality or cardiac arrest was estimated to be 12.4%. Overall, findings revealed reduced in-hospital mortality or cardiac arrest in correlation with use of 1mEq/L potassium bath for management of severe hyperkalemia (>6.5 mmol/L) in hospitalized ESRD patients.
