病人獲處方使用華法林(Warfarin)治療。護理師應監測哪項檢驗數據來評估治療成效?

A client is prescribed warfarin therapy. Which laboratory result should the nurse monitor to evaluate the effectiveness of the treatment?

  • ABleeding time
    出血時間
  • BaPTT
    活化部分凝血活酶時間
  • CPlatelet count
    血小板計數
  • DPT/INR✓ 正解
    凝血酶原時間/國際標準化比值
Explanation · 中文詳解

華法林為維生素 K 拮抗劑,影響凝血因子 II、VII、IX、X 的合成,臨床上以凝血酶原時間(PT)及其衍生的國際標準化比值(INR)來評估抗凝血效果。aPTT 是用於監測肝素(Heparin)的指標,兩者不可混淆。

Warfarin is a vitamin K antagonist that affects the synthesis of clotting factors II, VII, IX, and X. Its anticoagulant effect is clinically evaluated by means of the prothrombin time (PT) and its derived International Normalized Ratio (INR). aPTT is the indicator used to monitor heparin therapy, and the two tests should not be confused.

✦ 台美臨床差異

台灣與美國對於口服抗凝血劑的監測機制一致,皆以 INR 為準,並配合病患教育。
