Nowadays, the procedure for taking blood from a vein is quite popular in medicine. It is difficult to overestimate its benefit, because it allows you to determine the composition of the blood, which is simply necessary for many medical procedures. Many people are interested in why the bruise after taking blood from a vein does not disappear.
Causes of hematoma
The hematoma itself is a consequence of the fact that blood from a vein has entered neighboring tissues. It can occur instantly or after a day. Many are interested in why a bruise formed after taking blood from a vein. The first reason that immediately comes to mind is the low qualification of the health worker who performed this operation. But there are other reasons besides this.
The cause of a bruise at the site of taking blood from a vein may be:
- Low coagulability of blood, that is, it did not have time to stop corny before the patient removed the cotton wool.
- Thinning of the walls of the vessel.
- High blood pressure can cause excessive blood flow.
Excessive movement and fidgeting during the procedure allows for the possibility of additional damage to the walls of the vessel and, as a result, additional hemorrhage. Excessively rapid removal of cotton from the site of blood collection can also affect the appearance of a bruise. In addition to all this, the cause may be physical exertion on the arm.
Essence of treatment
The hematoma after the operation may disappear in a few weeks, however, you can speed up the restoration of the normal appearance of the hand and eliminate possible discomfort. In the first few days, you need to apply ice to the damaged area, and then, on the contrary, warm the bruise. This should be done to narrow the vessels and stop its enlargement, and then to expand the vessels, that is, speed up the metabolism, which will help dissolve the hematoma.
Ice is traditionally used for cooling, but it should be borne in mind that it must be wrapped in cloth to avoid frostbite on the skin.
To warm you can do alcohol compresses. You will need to take a piece of gauze, moisten it with water and alcohol in a ratio of 1: 1 (you can use vodka instead), wrap it with a cloth and apply it to the problem area for several hours or night. In addition, heparin ointment may be beneficial. It is also necessary to make a compress from it (spread a piece of gauze and wrap a film over the hematoma). You can also use gel from a bug (fresh-water sponge). Now pharmaceutical companies provide a wide range of different products.
ethnoscience
There are effective recipes for traditional medicine that will help get rid of a bruise after taking blood from a vein. To do this, dilute potato starch in water to a concentration of thick sour cream and then put on the hematoma for half an hour. In addition, you can still cook the following tools:
- Take a spoonful of plantain, fragrant rue and two glasses of water for each type of grass. Boil, cool and strain. Moisten cotton wool in both glasses in turn, squeeze, then also put on a bruise.
- Make pulp from grated onions. Apply to the bruise for no more than an hour.
- Prepare chamomile infusion and send to the freezer. Wipe the affected area with ice several times a day. If the algorithm for taking blood from a vein has been violated , then such an infusion will help eliminate soreness. For convenience, you can use special forms for freezing ice cubes.
You should know that alternative methods of treatment can do harm. Before using any infusion or other remedy, you should consult your doctor.
How to avoid injury
In order to avoid bruising after taking blood from a vein, it is important to take into account the qualifications of the health worker, so if possible you should find a reliable specialist.
In addition, knowledge of all the rules for taking blood from a vein and following the instructions of a health care provider is a guarantee of the safety of the procedure and the elimination of subsequent bruises. First of all, it is important:
- Keep calm during the procedure and do not move your hand, which can lead to injury to the walls of the vein.
- Do not interfere with the health care provider, but monitor his / her work. Know: first you need to remove the tourniquet, and only then remove the needle.
- Press the cotton wool moistened with the antiseptic received from the healthcare provider to the site of blood collection and bend the arm at the elbow. A bruise in a vein after blood sampling may occur if cotton wool is removed earlier than 10 minutes later.
- Until the end of the day, it is important to exclude any physical activity on the arm.
Prevention of Complications
It is very important to minimize the risk of blood poisoning. Infection can occur after this procedure if the laboratory assistant did not comply with the elementary rules for blood sampling. If you contact an experienced specialist, there will be no problems, and a bruise after taking blood from a vein will not form.
You need to know that an infectious infection threatens not only the health of the patient, but also his overall life, so you should take this seriously, despite the fact that taking blood from a vein is much safer than an intravenous injection.
To ensure personal safety, it is important to monitor compliance with the algorithm for taking blood from a vein:
- Use of sterile medical equipment by a healthcare provider (for example, a healthcare provider should print and wear gloves with you). In particular, it is important to monitor the use of a clean disposable syringe and needle for taking blood, because dirty ones can cause very undesirable complications, such as HIV infection.
- Treatment of the site of blood sampling with alcohol (not only the puncture site, but also the entire ulnar zone). Please note that the healthcare provider must treat the injection site before and after blood collection.
- Any contamination of the injection site should be avoided until it is completely healed.
And, of course, in no case should you neglect personal hand hygiene.
The opinion of doctors
As medical practice shows, a bruise after taking blood from a vein is a safe phenomenon that does not threaten the patient's life. In the event that a severe hematoma appears, it is imperative to visit a doctor and undergo a medical examination. If you take into account all the recommendations of a doctor, then you can reduce the risk of bruising to a minimum. If the doctor is a qualified specialist, then hematomas should not occur. It is also important to consider the general state of human health. If there are violations in the body, then often small hematomas occur.
