硫酸鎂（Magnesium sulfate）用於治療子癲前症，其中毒機轉為神經肌肉傳導阻斷。中毒的早期臨床徵兆是深部肌腱反射（Deep tendon reflexes, DTR）消失（如膝反射消失）。護理師必須定時檢查 DTR，若反射減弱或消失，應立即停藥並準備鈣離子劑，以防進展至呼吸抑制與心跳停止。
Magnesium sulfate is used to treat preeclampsia, and its toxicity is mediated by neuromuscular blockade. The earliest clinical sign of toxicity is the loss of deep tendon reflexes (DTRs), such as the disappearance of the patellar reflex. The nurse must regularly check DTRs; if reflexes diminish or disappear, the medication should be stopped immediately and calcium gluconate prepared to prevent progression to respiratory depression and cardiac arrest.
