Enoxaparin（低分子肝素）預充式針筒內含有氣泡（Air bubble），此氣泡設計旨在確保藥物完全進入皮下組織，並在拔針時封住針道，減少藥物滲漏至表皮引起瘀青或刺激，因此注射前不可排出。注射部位應選擇腹部皮下脂肪層，並捏起皮膚以確保藥物送入正確層面，避免誤入肌肉組織，注射後禁止按摩以免造成組織出血。
The nurse should pinch the skin fold to ensure the enoxaparin is injected into the subcutaneous adipose tissue rather than the muscle. The air bubble in the prefilled syringe should not be expelled, as it helps deliver the full dose and seals the needle track to prevent leakage and bruising.
