— Explanation · 中文詳解 —
Enoxaparin（低分子量肝素）的預填式針筒中含有空氣泡，其設計目的是在注射完成後，空氣能將殘留於針頭內的藥液推入皮下，並封住針道，以減少藥液外漏及注射部位的瘀青形成。因此，護理師不應將其排出。其他操作如腹部注射、輪替部位及使用原廠預填針筒皆為正確程序。給藥後不應揉搓注射部位，以防造成微血管出血。
The air bubble in the pre-filled enoxaparin syringe is intentionally designed to push the remaining medication into the subcutaneous tissue and seal the injection tract after administration. Expelling this bubble is incorrect as it may lead to medication leakage and increased bruising at the injection site.
