病人正在進行肝素輸注。護理師應監測哪項檢驗數據以調整輸注速率?

A patient is receiving Heparin infusion. Which of the following lab values should the nurse monitor to adjust the infusion rate?

  • APlatelet count
    血小板計數
  • BBleeding time
    出血時間
  • CaPTT✓ 正解
    活化部分凝血活酶時間
  • DPT/INR
    凝血酶原時間/國際標準比值
Explanation · 中文詳解

肝素(Heparin)的作用主要是透過抑制凝血因子,臨床監測標準為活化部分凝血活酶時間(aPTT)。PT/INR 是用來監測 Warfarin,而非 Heparin。血小板則是為了監測 Heparin 誘導的血小板減少症(HIT),但調整劑量依據為 aPTT。

Heparin works primarily by inhibiting coagulation factors; the standard clinical monitoring parameter is the activated partial thromboplastin time (aPTT). PT/INR is used to monitor warfarin, not heparin. Platelet count is monitored to detect heparin-induced thrombocytopenia (HIT), but dose adjustment is based on aPTT.

✦ 台美臨床差異

美台臨床皆以 aPTT 作為肝素監測重點,且皆使用標準化給藥流程(Heparin Protocol)。
