— Explanation · 中文詳解 —
Furosemide 是排鉀利尿劑（Loop diuretic），會導致尿液中大量流失鉀離子。低血鉀（Hypokalemia）是使用此藥最常見且嚴重的副作用，容易誘發心律不整，因此給藥前務必確認血鉀濃度是否在安全範圍內。
Furosemide is a potassium-wasting diuretic (loop diuretic) that causes large amounts of potassium to be lost in the urine. Hypokalemia is the most common and serious side effect of this medication and can easily provoke arrhythmias. Therefore, before administering it, the nurse must confirm that the serum potassium level is within a safe range.
✦ 台美臨床差異
台灣醫院常規開立利尿劑時，常會同時開立口服鉀離子補充劑，美國則視實驗室報告彈性調整。
