— Explanation · 中文詳解 —
毛地黃（Digoxin）治療窗極窄，中毒風險高。中毒的臨床表現包括腸胃道不適（如噁心、嘔吐、厭食）與視覺異常。視覺上的黃綠色光暈（Yellow-green halos）是該藥物中毒非常特異性的臨床徵象。臨床思路應強調監測藥物血中濃度與臨床症狀，特別是當病人出現視覺改變時，應立即停止給藥並檢查血中濃度。
Digoxin toxicity is indicated by specific visual disturbances, particularly seeing yellow-green halos around objects. Other common signs include gastrointestinal symptoms like anorexia and nausea, as well as lethargy, rather than hypertension, hyperactivity, or increased appetite.
✦ 台美臨床差異
在美國臨床，護理師在給予毛地黃前，必須先測量心跳（Apical pulse），若心跳低於 60 bpm 需暫停給藥並回報，這是 NCLEX 考試中關於此藥物的必備知識。
