硫酸鎂（Magnesium sulfate）廣泛用於子癇前症（Pre-eclampsia）以預防癲癇發作。其藥理機轉具有神經肌肉阻斷作用，過量易導致中毒。評估優先級遵循「安全性」原則，深腱反射（Deep tendon reflexes, DTR）消失通常是中毒的最早期徵象，隨後可能出現呼吸抑制與心跳停止。
Deep tendon reflexes are the priority assessment for patients receiving magnesium sulfate because loss of reflexes is often the earliest sign of magnesium toxicity. Monitoring this allows for early intervention before progression to respiratory depression or cardiac arrest.
