Losing blood from veins is not always safe and everywhere

A blood sample is not the same for everyone. While one of the sentences is like "Oh, what beautiful veins. They almost jump against me ", other patients in turn experience a hectic doctor's assistant who finds no suitable vein for puncturing. But this is quite normal, because like other parts of the body, the blood vessels are very different from person to person. In addition, it is important to decrease the blood on the experience of the blood collector.

Blood is usually taken in the elbow
Almost everyone has at least once experienced a blood loss. This usually takes place from the patient's elbow, who should sit or lie down while doing so. In order to make the vein, which is to be punctured, more visible and thus facilitate the blood collection, the blood flow is usually on the upper arm using a cuff or similar. briefly dammed. Nevertheless, it may be difficult for the doctor or the medical assistant to find a suitable vein or to puncture at all, explains the Chairman of the Bremen Doctors' Association, Hans-Michael Mühlenfeld, in an interview with the news agency "dpa".

Veins often become harder to find overweight
Because "veins are like noses and ears: very individual," explains the physician. In addition, there are anatomical features that can complicate the finding and tapping of a blood vessel. Since the blood vessels that carry the blood back to the heart are under the subcutaneous fatty tissue, they are accordingly e.g. Partially hidden in people with obesity and obesity. According to Mühlenfeld, even small patients sometimes experience problems, because "infants between half and two years often have a lot of bacon." Well-trained, athletic people with little fatty tissue and lots of muscles, on the other hand, would make it easy for the doctors because the veins in In this case, it is usually quite clear.

In order to make his veins more visible as a non-athlete, it is important, according to Mühlenfeld, to drink a lot. Therefore, a lot of fluid also causes more flow in the veins and this in turn can facilitate the search for the "ideal vein". Another trick is to warm up the forearms, which would relax and dilate the veins.

Experience of the blood collector is crucial
If the blood collection is not as it should, according to the experts also be a connective tissue weakness of the reason. As a result, the walls of the veins lose their elasticity and tend to break. If the vein is not hit properly, a bruise can quickly develop. Whether losing the blood works well or not, but in any case depends only to a certain extent on the constitution of the patient. The "decisive factor" for the successful implementation is namely the experience of the blood collector, emphasizes Mühlenfeld. (No)
