when we get out blood for one analyticsthe person doing the extraction is always telling us to tighten up during five minutes. Sometimes a patch is applied to prevent too much blood from being shed. Other times, they just leave a cotton swab for us to press. Be that as it may, sometimes we need to drive immediately, or we don’t want to walk down the street with our sleeves rolled up in the middle of winter, or it’s just uncomfortable to walk holding on. And what’s going on? Those five minutes turn into 30 seconds, and then we wonder if we get hematoma for mining.
Because yes, sometimes the toilet is blamed for the bruise, but the truth is that something as simple as a wrong press can further explain why this unpleasant situation occurs. And the truth is, that’s what we all know. After drawing blood, you must click to prevent them from appearing. bruises, Correctly. But why?
Perhaps, knowing the reasons, the next time we draw blood, we will prefer to wait a bit before getting into the car or going out into the cold winter (if it comes back) with our sleeves rolled up.
What is a bruise?
Before considering why we bruise if we do not force ourselves after a blood test, it is useful to know what is hematoma.
Basically it can be defined as an accumulation of blood due to a small internal hemorrhage, not reaching skin surface. This usually occurs when small blood vessels, such as capillaries, rupture. This can happen for a variety of reasons, although it most often occurs due to more or less intense impacts. But also by scratches or when we perform blood analysis.
Why do you need to compress after taking blood?
When they take blood from us, they use intravenous needle, which reaches the walls of the veins and penetrates them to extract their contents. When removed, the resulting hole may cause diffusion of blood into the subcutaneous tissue. As a result, this builds up and can lead to bruising.
The more blood flows, the bigger the bruise will be. However, if we put pressure on the wound from the needle, we will prevent it. Mainly because the blood collects at most in one place, but it will not spread over the arm.
No need to spend a lot of time pressing. What from five minutes Tentatively, there are no exact dates. However, if we have adequate coagulation, by this time the bleeding will already have stopped and we can avoid a hematoma.
Of course, it is important to press constantly and stationary. Namely, we can’t move our fingers in circles while we are squeezing, because in this case we could further promote the spread of blood under the skin.
In short, if after drawing blood you put pressure on the wound just enough to get away from the first-aid post, then don’t complain if you get a bruise. If we are told to press for five minutes, it is not for pleasure, but for our own good.
