Precautions for subcutaneous injection

When injecting hypodermic needles, the local anatomy of the body must first be clarified to avoid injury to blood vessels and nerves during injection. Alcohol should be used before and after injection. The syringe should be pulled out. 45 degrees, can avoid local muscle damage. Before injection, observe whether the local skin is damaged or swollen or allergic. If any, the injection site should be replaced. For some patients who often need subcutaneous injections, such as diabetic patients, they need to frequently inject insulin under the skin. Change the site frequently, and the injection must be precise. For injection of less than 1ml of liquid medicine, a 1ml syringe must be used. When piercing the skin, draw back first to determine whether the blood vessel is damaged. During the infusion, try to avoid severe pain as slowly as possible. The gas in the syringe must be drained before the infusion. Pay attention to disinfection and hemostasis.
