Hyperkalemia (HK) is one of the most frequently observed hydro electrolyte disorders in patients (Pts) with severe renal dysfunction and especially in those under maintenance hemodialysis (HD). Its relevance lies in the potential risk for the development of serious arrhythmias and increased mortality. Missing HD sessions and even after the long interdialytic period (LIP) increase the risk of its occurrence. The main aim of this study was to assess the impact of the LIP on serum potassium concentration K + and verify if these differ from those usually recorded at midweek (MW).
