肝素(Heparin)是一種抗凝血藥物,主要透過抑制凝血因子(特別是凝血酶與 Xa 因子)來發揮作用。為了監測其治療效果及預防過度抗凝導致的出血風險,臨床上使用活化部分凝血活酶時間(aPTT)作為標準監測指標。理想的治療範圍通常設定為控制組(Normal control)的 1.5 到 2.5 倍。護理師應定時抽血監測 aPTT,並觀察有無出血徵兆(如牙齦出血、血尿、瘀斑)。
The activated partial thromboplastin time (aPTT) is the standard laboratory value used to monitor the therapeutic effect and safety of heparin therapy. Monitoring aPTT helps ensure the medication remains within the therapeutic range to prevent clotting while minimizing the risk of bleeding complications.
