Peripartum Hyperkalemia Caused by Magnesium Infusion in a Woman With End-Stage Renal Disease: A Case Report.

Pregnancy in the setting of renal failure has higher rates of adverse events necessitating increased monitoring and treatment. Pregnant women with end-stage renal disease have higher rates of hypertension, and 50% of pregnancies are complicated by preeclampsia. We describe the case of a 32-year-old parturient with end-stage renal disease on hemodialysis with superimposed preeclampsia who developed clinically significant hyperkalemia with electrocardiographic changes after magnesium infusion.
