Some elderly people often have varicose veins, which can even cause embolism. For this type of disease, there are drugs to prevent and treat it, usually enoxaparin sodium, which is an injection. Patients need to go to hospital for professional injection treatment.

　　Enoxaparin should be given subcutaneous deep injection for the prevention of venous thromboembolism, treatment of deep venous embolism, treatment of unstable angina pectoris and non-Q wave myocardial infarction. Intravascular administration during hemodialysis and cardiopulmonary bypass; For acute myocardial infarction with ST-segment elevation, initial treatment is intravenous followed by subcutaneous injection.

　　Subcutaneous injection technique: The dosage of enoxaparin can be adjusted according to the patient's body weight. The excess amount must be discharged before injection, but the air bubbles in the syringe need not be discharged before injection. A syringe pre-loaded with liquid medicine can be used directly. The injection should be given after the patient is lying flat. It should be administered alternately in the anterolateral or posterolateral subcutaneous tissue of the left and right abdominal walls. During the injection, the needle should be inserted vertically into the skin, but not at an Angle. Throughout the injection, the skin is picked up between your thumb and forefinger, and all the needles are inserted into the fold to give the injection.

　　After each injection, the drug needs to be fully metabolized before the next injection, so as not to cause too much load on the body. In addition, because the treatment is for a variety of diseases, the drug must be administered on a case-by-case basis.
