Low molecular weight heparin sodium injection, what should be done during the procedure to reduce these possible adverse reactions?

  1. Massage the skin for 2 minutes before operation to make the skin red and accelerate blood circulation at the injection site. Promote capillary dilation, promote drug absorption, reduce local drug concentration as soon as possible, reduce the incidence of subcutaneous bleeding. At the same time can increase the comfort of patients, reduce the patients nervous psychology!

  2. Site selection: for subcutaneous injection of LMWH, the abdomen, the lower margin of deltoid muscle of the upper arm and the abdomen can be selected as the preferred site.

  Abdominal hypodermic injection of low molecular heparin sodium to take the supine kneeling position: because the patient is rich in subcutaneous tissue, the injection range is relatively large, supine kneeling position easy to make abdominal wall muscle relax, make the formation of wrinkles, capillary relaxation and bending, not easy to damage, reduce the occurrence of subcutaneous bleeding.

Low molecular weight heparin sodium injection, what should be done during the procedure to reduce these possible adverse reactions?

  Methods: select periumbilical U shape, area, under the navel 5 CMP. About 10 cm (except the umbilical week 1 cm), each time interval injection in turn according to the order twice injection point distance above 2 cm, left, to avoid injury, induration and scar left thumb and forefinger knead dead skin forms folds, and maintain and finished injection and relax skin, right hand holding syringe clingy vertical needle into the skin, fat injection depth, according to the patients in general for the length of the needle 1/2 ~ 2/3, sure no slow injection after 30 s.

  Injection at the lower edge of deltoid muscle of the upper arm: the patient was placed in a comfortable position, and the needle inclined to the surface of the skin was punctured 30° ~ 40 ° rapidly, with a depth of 1/2~2/3. The injection was slowly pushed after no blood was returned.

  3, generally do not exhaust gas before injection, one is to ensure complete use of the liquid, accurate dosage, to ensure the efficacy; Second, it can effectively reduce the appearance of ecchymosis at the injection site. Inside the syringe injection, a small amount of air to the syringe, handheld needle, rapid Pierce, avoid excessive force, injection too deep, it is beautiful deep fat layer, and fixed injection needles, withdrawing without h. slow injection solution, finally left the little push air to avoid residual liquid in the needle, pull out the needle in order to avoid out of the solution, should press the piston. Effective communication with the patient during the injection and diversion of attention can relieve the pain caused by the low dosage of the injection

  4. Needle extraction: stay for 10s after injection and then vertically remove the needle. Please pull out the needle according to the original needle entry Angle and gently to avoid damaging capillary tissue.

  5. Apply pressure for 5 to 10 minutes, preferably at a depth of 1cm or less. Avoid injecting patients with abdominal belt, belt.

  6. After the injection, observe the pain at the injection site. Do not rub or apply hot compress. Observe the skin condition of the injection site within 12~24h. Observe the patient's whole body condition, such as the color and character of stool, whether there is bleeding of gums and nasal wings, etc. If abdominal scleroma, ecchymosis >2cm, and obvious pain should be alert to the occurrence of bleeding. If subcutaneous bleeding formation of 2cm*3cm ecchymosis, at this time, the patient appropriate to reduce activities, cold compress, in order to reduce the amount of bleeding and reduce peripheral nerve sensitivity, reduce pain!
