For blood glucose self-monitoring, blood collection is essential. Therefore, people with diabetes regularly take the blood with a lancing device. Many find this painful, as they mistakenly remove the blood directly in the middle of the fingertip and not as recommended on the side of the fingertip. In order to prevent the sensation of pain, we give you some suggestions here and reveal tricks on how to make a gentle "click" out of the sting on the lateral finger-berry. First, let's give you a few pointers on what to watch out for when getting blood.
Every skin is different
In order to reach the sufficiently perfused areas in the skin during stinging, the lancet must pierce the uppermost skin layer (epidermis, epidermis).
The epidermis on the hands and fingers, however, varies from person to person and is exacerbated in places by external influences such as work in the garden or manual activities. The thickness of the horny layer may vary from 0.05 to 1.0 millimeters due to these various fingertip influences. The underlying germ layer is between 0.1 and 0.2 millimeters thick.
Also, there are no blood vessels, but already the first nerve endings, which respond to mechanical and chemical stimuli and to temperature stimuli. In order to achieve a site with sufficient blood supply, a lancing device must therefore puncture penetration depths of between 0.15 millimeter and 1.2 millimeters as accurately as possible and with as little pain as possible for the respective person. Because only the underlying skin layer, the dermis, contains the smallest blood vessels.
Tips for a correct blood collection
So, the blood is easily from the hand and you come to the right measurement results.
- Adjust all measuring utensils such as blood glucose meter, test strip, lancing device with lancet and diary.
- Warm hands: Before taking blood, your hands should not be too cold. Otherwise, the escaping blood volume is not always sufficient for the measurement. Gently massage your fingers to promote blood circulation.
- Wash hands: Wash your hands before taking the blood. Otherwise, sugar residues (for example of fruit) on the fingers can simulate high blood sugar levels. If you wash your fingers with warm water, you will also improve blood circulation. Please also make sure that your hands are well dried. Do not disinfect your hands. Only in exceptional cases, if, for example, you carry out work associated with dirt and it is not possible to clean your hands on site, you can use alcohol swabs. Let the alcohol evaporate completely. Otherwise, alcohol and blood mix, which can lead to false readings.
- Massage hands: After stinging, it often takes a while for the blood to escape. Be patient and massage your finger gently from palm to fingertip. This light pressing is allowed. Since hardly any tissue fluid escapes, there is also no danger of false measurement results. So you can already measure your blood sugar with the first drop of blood.
Tips for a poorer blood production
They can do "all sorts" to ensure that blood production is largely painless. Here are some little tricks with a big impact.
- Remove blood from the side of the fingertip. There is a strong blood supply guaranteed, the pain sensation but very low.
- Take blood from different fingers regularly. Right-handed people should, for example, also peck at the fingers of the right hand. By changing less keratinization, which complicate the blood production.
- Preferably, remove the blood from the sides of the fingertip of the middle, ring and little fingers. Thumb and index finger disturb the smallest injuries, because we grab a lot with these fingers.
- Press the lancing device firmly against the skin during blood collection. So you can reduce the penetration depth and the associated pain sensation.
- Firmly squeeze the affected skin for about 30 seconds after taking blood. This will prevent rebleeding, which can lead to small bruises and thus to pain.
- It is recommended to change the lancet of the lancing device before each blood collection.
Because your hands are worth it ...
Your hands are regularly "pissed" during blood collection. Why do not you give them even an extra dose of care? We recommend a wellness program from hand bath to manicure. Begin by pampering your hands with a lukewarm, oily bath (for example, a tablespoon of olive or almond oil in warm water). The hand bath should not take too long. This dries out the skin. Then dry your hands well - especially between the finger gaps.
With a scrub, for example from olive oil, sea salt and liquid honey, you can then refine the skin texture on the hands. Rough spots and cornifications disappear as a result. But be careful not to scour the skin too much. Apply then with a hand mask quietly once thickly.
Use a face mask, for example with vitamin E, and wrap your hands over it with clingfilm. After ten minutes exposure, you have real "velvet paw". Whoever wants to do a manicure should use a nail file. Nail scissors can easily lead to injuries that can lead to infections. In addition, they should refrain from pushing back the cuticles.
