Magnesium Toxicity in an Obstetric Patient Due to Preeclampsia-Related Renal Dysfunction Despite Administration of a Standard Pritchard Regimen: A Case Report

Magnesium toxicity could occur in the treatment of preeclampsia/eclampsia, especially when the patient has coexisting renal impairment. If undetected and promptly treated, hypermagnesemia can cause severe fetomaternal complications and death. We present the case of a 22-year-old pregnant woman at 32 weeks of gestation, who was referred to our hospital with eclampsia, treated with intramuscular magnesium sulfate following a standard Pritchard regimen. An emergency cesarean section was carried out under general anesthesia due to multiorgan dysfunction. Following the cesarean delivery, she was successfully managed with mechanical ventilation and hemodialysis.
