護理師照護一位接受肝素(Heparin)靜脈輸注的病人。哪項實驗室數值監測最重要?

A nurse is caring for a client receiving heparin infusion. Which lab value is most important to monitor?

  • AaPTT✓ 正解
    活化部分凝血活酶時間 (aPTT)
  • BPlatelet count
    血小板計數
  • CHgb and Hct
    血紅素與血容積 (Hgb and Hct)
  • DPT/INR
    凝血酶原時間/國際標準比值 (PT/INR)
Explanation · 中文詳解

肝素(Heparin)的作用監測指標為 aPTT(活化部分凝血活酶時間)。PT/INR 是監測華法林(Warfarin)的指標。血小板(B)需監測以防 HIT(肝素誘發血小板減少症),但在調整 Heparin 劑量時,aPTT 是最直接的臨床調整依據。

The activated partial thromboplastin time (aPTT) is the primary laboratory value used to monitor the therapeutic efficacy and adjust the dosage of heparin infusions. While platelet counts are monitored to detect heparin-induced thrombocytopenia, aPTT directly reflects the anticoagulant effect required for safe treatment.

✦ 台美臨床差異

兩地對於 Heparin titration 均有嚴格的 protocol,aPTT 數值直接連動輸注流速的調整。
