Enoxaparin（低分子量肝素）的預充式針筒內含空氣泡，其設計目的是確保病人能完整注射到標定劑量，因此注射前不應排出空氣。施打時應選擇腹部皮下組織，注射後絕不可按摩注射部位，因為按摩會破壞皮下微血管，增加瘀血或血腫（Hematoma）的風險，且不需要回抽血液（Aspiration），因為這會造成組織損傷。
When administering subcutaneous enoxaparin, the nurse should inject the medication into the abdomen while leaving the air bubble in the pre-filled syringe to ensure the full dose is delivered. Aspiration and vigorous massage of the site should be avoided to prevent tissue trauma and hematoma formation.
