靜脈輸注肝素（Heparin）是一種高警訊藥物（High-alert medication），具有強效抗凝血作用，使用不當極易導致大出血。因此，監測凝血功能是強制性的，臨床上主要依據 PTT（部分凝血活酶時間）來調整劑量。護理師必須定期根據醫囑抽血監測 PTT，並觀察病人有無出血徵象（如牙齦出血、瘀斑、血尿）。
IV heparin infusion is a high-alert medication with potent anticoagulant effects; improper use can readily cause major bleeding. Monitoring coagulation function is therefore mandatory, and PTT (partial thromboplastin time) is the primary parameter used to adjust the dose clinically. The nurse must obtain regular PTT samples per the provider's order and observe the client for signs of bleeding (such as gum bleeding, bruising, and hematuria).
