Key points for attention in injection of low molecular weight heparin sodium

  Heparins Manufacturer says low-molecular-weight heparin sodium is a newly developed anti-blood suppository made from the decomposition of common heparin. Compared to heparin, it has higher bioavailability, longer half-aging, stronger antithrombotic effect, less bleeding and risk, fewer adverse behavior reactions, and no need to be tested by test methods. In clinical research can mainly be used for: treatment of unstable angina pectoris and non-Q wave centrifuge infarction; Prevent the risk of thrombus formation related to the method of surgery.

  When using low molecular weight heparin sodium, it is easy to cause pain, subcutaneous hematoma, scleroma, abdominal wall hematoma and so on. It creates tension and fear for the patient and family and may also affect the absorption of the medication, never reducing the effectiveness of the treatment. These reasons are related to injection site, shallow injection, rapid injection, needle extraction method, residual liquid, and pressing time and intensity.

  1. Massage the skin for 2 minutes before operation to make the skin flush and accelerate the blood circulation at the injection site. Promote telangiectasia, promote drug absorption, reduce local drug concentration as soon as possible, reduce the incidence of subcutaneous bleeding. At the same time can increase the patient's comfort, relieve the patient's tension.

  2. Site selection: Subcutaneous injection of low molecular weight heparin sodium can be used for treatment by selecting the abdomen, the lower edge of upper arm deltoid muscle, and the abdomen as the preferred target site.

  Abdominal subcutaneous injection of low molecular heparin sodium to supine position: patients with subcutaneous tumor tissue rich students, injection time scope economy is relatively large, supine, easy to make abdominal muscle relaxation, form wrinkles, sagging bending is capillary cells, through damage, reduce lead to subcutaneous bleeding.

  Methods: A U - shaped area around the umbilical cord was selected, 5cmp.

  Injecting the lower edge of upper deltoid muscle: the patient is in a comfortable position, and the needle is inserted into the skin at a depth of 1/2 to 2/3 at a bevel of 30 to 40 degrees. After the inhalation, the liquid is slowly injected.

  3, generally do not exhaust before injection, one is to ensure that the liquid through the use of a complete, accurate dose, to ensure the efficacy of the product; Second, effective methods can be obtained to reduce ecchymosis at different parts of self-injection. Research the air inside the syringe injection, a small amount of above to the syringe, handheld needle, rapid Pierce, avoid greatly too forcibly students, injection too deep, is better to in-depth analysis of fat layer, need fixed needle injection at the same time, back to inject liquid smoke no h. slow development, finally put the little push air to avoid enterprise residual liquid in the needle, When pulling out the needle, the piston should be pressed in order to avoid the culture taking out the liquid. Providing effective communication with the patient during the injection and distracting the child can ease the pain caused by low-volume injection techniques

  4, needle pulling: after injection stay for 10 seconds, vertical needle pulling. Pulling needle Angle should be the same as the original needle Angle, and the movement should be gentle, so as not to damage the capillary tissue.

  5, press: press for 5~10 minutes, press the degree of skin sag or slightly sag, the depth is not more than 1cm. Avoid injecting patients with abdominal bands and belts.

  6. After the injection, we can observe the pain management of different parts of the injection, and pay attention not to rub or apply hot compress. The skin development at the injection site was observed closely within 12~24h. During the use period, the students observed and analyzed the patients' ability to use the stool in their whole body, such as stool color, stool character, gingiva, nasal alar bleeding, etc. If the abdominal induration, ecchymosis >2cm, and the pain degree is obvious, we should be alert to the occurrence of bleeding. If the risk of subcutaneous bleeding forms 2cm*3cm ecchymoplasty, the patient should be provided with appropriate and effective reduction of economic activities and cold compress to reduce the amount of bleeding and peripheral nerve sensitivity, and reduce pain!
