Enoxaparin（低分子量肝素）的預充式針筒內含有一個小氣泡，這是為了確保在注射時能將藥物完整推入組織，並減少針頭殘留藥物，進而降低注射部位的局部皮下出血（瘀青）。因此，絕對不可將此氣泡排出。護理師在進行皮下注射時，需選擇腹部（避開肚臍周圍）、不按摩注射部位、並輪替注射點，以維持藥物吸收與組織健康。
The air bubble in the pre-filled enoxaparin syringe is intentional and should not be expelled, as it ensures the full dose is delivered and minimizes medication residue in the needle. Expelling the bubble could result in an underdose. The abdomen is the preferred injection site, and rotating sites while avoiding massage helps prevent tissue irritation and bruising.
