Experts see the right injection technique as an important element of effective insulin therapy. Insulin is injected into the subcutaneous fat tissue (subcutaneously) from the abdomen (rapid insulin uptake) or into the outer thighs (slow insulin uptake), but also the buttocks and upper arm are conceivable. When injecting a skin fold is formed with the thumb and forefinger, thereby reducing the risk of injection into the muscle.
Injection technique is important
In order to ensure an optimal distribution of the insulin in the adipose tissue, the insulin should be injected slowly and the needle should be removed only ten seconds after the complete injection. Another important aspect of optimal insulin injection is the correct injection angle. If a skin fold is formed, it is possible to pierce at an angle (45 degrees) as well as vertically (90 degrees) and select the needle length according to the thickness of the lower fat tissue.
What must a diabetic pay attention to when insulin is injected?
- The right spraying technique is important: insulin should always be injected subcutaneously, ie into the fatty tissue that lies above the muscle. Here it can be best distributed.
- "Change places": If a patient injects too often in the same place, among other things, lipohypertrophies (thickening of the fatty tissue) can form, and the insulin can no longer be properly absorbed in these areas. The injection sites should therefore be changed regularly, preferably according to a fixed "rotation principle". The spraying parts should be at least three cm apart. Help also offers the patient a so-called rotation template.
- The main thing about changing the needle: Reuse of the pen needle causes wear on the needle, which, among other things, can lead to additional minimal damage to the tissue and thus to a change in insulin uptake into the bloodstream. The signs of wear on the needle tip are not visible to the naked eye. Therefore, a new needle should be placed before each injection.
How can pain be avoided with insulin injection?
To significantly reduce the inconvenience of insulin injection, thinner, shorter, and sharper needles have been developed with a special lubricating film. The lubricating film ensures an almost painless injection. Reuse will affect the performance and safety of the needles. Both the loss of the lubricant and the damage to the needle tip increase the inconvenience of the injection.
