— Explanation · 中文詳解 —
依諾肝素為低分子量肝素。給藥時應將藥物注射至腹部脂肪層，針頭以 90 度垂直插入。不需回抽（aspirate）因為這會造成瘀青，也不可按摩針孔處。預充式針筒內的氣泡設計是為了確保病人能完整攝取劑量，不應刻意排出。
Enoxaparin is a low-molecular-weight heparin. The drug should be injected into the abdominal subcutaneous fat with the needle inserted at a 90-degree angle. Do not aspirate, because this can cause bruising, and do not massage the injection site. The air bubble in the prefilled syringe is intended to ensure that the client receives the full dose and should not be intentionally expelled.
✦ 台美臨床差異
台灣與美國臨床做法一致，強調衛教病人預充式針筒的氣泡不可排出。
