硫酸鎂（Magnesium sulfate）是治療子癇前症與預防癲癇的首選藥物，但其毒性指數狹窄。中毒的最早期跡象是「深部肌腱反射（DTR）消失」，這發生在血中濃度過高且可能導致呼吸抑制之前。護理師必須在治療期間嚴密評估 DTR，若反射減弱或消失，必須立即暫停輸注並通知醫師。這是臨床評估中最即時且敏感的指標。
Magnesium sulfate has a narrow therapeutic index, and the earliest clinical sign of toxicity is the loss of deep tendon reflexes. This symptom appears before respiratory depression occurs, making the assessment of deep tendon reflexes the most immediate and sensitive indicator for detecting potential toxicity during treatment.
