- AAspirate before injecting the medication注射前進行回抽
- BExpel the air bubble from the prefilled syringe排出預充式針筒內的空氣氣泡
- CMassage the site vigorously after injection注射後用力按摩注射部位
- DInject into the abdominal wall✓ 正解注射至腹部壁
— Explanation · 中文詳解 —
依諾肝素通常以預充式針筒提供，建議注射在腹部皮下脂肪層。該針筒內含小氣泡，目的在於確保藥液完全進入皮下，不可排出。注射時不需回抽（Aspiration），且注射後應避免按摩該部位，以預防皮下出血或血腫發生。
The abdomen is the preferred site for subcutaneous enoxaparin administration to ensure consistent absorption. The air bubble in the prefilled syringe should not be expelled, as it helps seal the medication within the subcutaneous tissue. Aspiration is contraindicated to prevent tissue trauma, and vigorous massage after injection should be avoided to reduce the risk of bruising or hematoma formation.
