— Explanation · 中文詳解 —
肝素（Heparin）皮下注射標準位置為腹部，需避開肚臍周圍 2 英吋。注射時不可抽吸（避免挫傷）也不可按摩（避免出血及血腫），使用小針頭（通常 3/8 或 1/2 英吋）即可。腹部脂肪組織適合藥物緩慢吸收。
The abdomen is the preferred site for subcutaneous heparin administration due to consistent absorption rates. Aspiration is contraindicated as it causes tissue trauma, and massage should be avoided to prevent hematoma formation. A short needle (typically 3/8 to 1/2 inch) is used to ensure proper subcutaneous delivery without entering muscle tissue.
✦ 台美臨床差異
兩地均強調不可按摩，但台灣臨床偶見老一輩護理師習慣按摩，需注意遵循標準作業程序 (SOP)。
