Evaluating intradialytic change of serum magnesium and its relation to intradialytic complications in chronic hemodialysis patients during one-month period

Introduction: The most common important complications of hemodialysis are hypotension, muscle cramps, nausea and vomiting, which play a significant role in the process of dialysis and in the patient’s lifestyle. Objectives: This study aimed to investigate the impact of serum magnesium on incidence of dialysis complications. Patients and Methods: Two blood samples were obtained from all the patients who were eligible to enter the study for checking their serum magnesium before and after dialysis. Blood pressure was recorded before and after dialysis since the symptoms of cramp, nausea and vomiting were evaluated during dialysis. Results: Decreased serum magnesium level, throughout dialysis, had a significant direct correlation with intradialytic hypotension (IDH). Conclusion: Intradialytic hypotension had a direct correlation with the reduction of magnesium level during dialysis.
