What is it like to have blood drawn? What are the consequences of a blood draw?

Every time you have an empty physical examination, you will faint when you draw blood! I don't know why, it's been like this since high school, and after a few tens of seconds of smoking, I start to get dizzy, my eyes are glazed, I want to vomit, I feel nauseous, I must sit or I will definitely not be able to stand.

There is a feeling that "the wind is sluggish and the water is cold, and the strong man will never return". Anyway, I'm afraid of injections and blood draws. I was so dizzy and dizzy.

The needle used to draw blood is similar to the needle used to make a hanging bottle, and it doesn't hurt much to pierce it. The doctor said that I was faint, but when I pulled out the needle, I saw it, and I didn't like it, I disliked myself.

The first time I was drawn blood was the physical examination at the beginning of my freshman year, and the senior sister of the nursing department took a 10ml syringe to draw, and the senior sister told me not to be afraid, don't tremble.

I don't think it's anything to smoke for others, my eyes were black when I was pumped myself, I was dizzy, it was so embarrassing, I actually fainted.

When I went to the hospital, I was afraid that my health would not be good, so the doctor recommended a physical examination, holding the glass tube containing blood, looking at the queue in front, worrying about whether there would be anything wrong with my body, and looking at the syringe in front of me to draw blood. I was a little faint again.

It hurts, although I am a doctor, but I don't dare to prick it myself!

Every time, I pray that I will meet a good technique, because I am afraid of the sting.

Drawing blood and injections, two words that scared me when I heard them from childhood to adulthood.

The blood was drawn on an empty stomach, and after the blood was drawn, he got up and left. When I checked my eyes, I suddenly felt that my eyes were black and my head was buzzing, and I was unconscious.

Blood is drawn with a vacuum tube. The vacuum tube is leaking. The doctor pricked the poor vein over and over again, but it didn't bleed. After a dozen stabs, he gave me a different tube. And the blood was drawn out.

It is possible to perform examinations, laboratory tests, and it is also possible to understand the condition of the body, which is conducive to checking the condition of the disease, and it is possible to understand the problem of the blood. After the final tests, they are all discarded, and after accurate blood data is obtained, all the blood is disposed of.

It is used for testing, checking blood type, blood condition, and checking whether there are other diseases, some of which will be thrown away because it is useless after the examination, and some of which will be left for blood group preservation.

These blood are sent to the laboratory for routine examination, through which the blood can be understood blood routine, liver and kidney function, blood sugar, and blood lipids, so as to judge the health of the body.

Test common sense - precautions when taking blood for testing Blood test is a common thing when seeing a doctor, the doctor requires the patient to draw blood for a variety of blood index tests to make a clear diagnosis or differential diagnosis, and to carry out targeted and rational drug use. So, what are the precautions that need to be paid attention to during the whole process of blood testing? The first thing to do is to ask the doctor what to look out for when taking blood from the test request form.

Different laboratory items have different requirements, and a small number of emergency laboratory items such as blood routine, dielectric, cardiac enzyme spectrum, troponin, amylase, etc., can be tested at any time due to urgent needs of the condition. Most biochemical, immunological, and radioimmunoassay items such as liver function, kidney function, two and a half, anti-"O", rheumatoid factor, tumor antigens, hormone assays, and AIDS antibodies require blood to be drawn on an empty stomach in the morning or fasting for more than 6 hours. Blood lipid analysis, blood glucose, blood sedimentation rate, blood viscosity and other laboratory items are susceptible to the influence of diet, blood must be drawn on an empty stomach, especially blood lipid analysis, because chyle micronism can occur after eating, which seriously affects the measurement results, so it is required to fast for more than 12 hours to draw blood.

Many drugs can affect the results of blood markers, so patients who need to take drugs every day should ask whether they can stop taking the test before the blood is drawn. You should get enough sleep at night before blood drawing, and you should not do strenuous exercise in the morning, because strenuous exercise can also change the concentration of various blood indicators and affect the measurement results. If you have stomach discomfort on an empty stomach, you can drink a small amount of plain water, but do not drink milk.

Those who do glucose tolerance test and insulin stimulation test should bring glucose powder. In the morning, you can go to the hospital blood collection center or outpatient laboratory 10 minutes in advance, so that your body and mind can adjust to a stable state before drawing blood. When taking blood, you should give all the test application forms to the doctor to avoid missing the test.

In autumn and winter, clothes are often worn, and coats and thick sweaters must be taken off to avoid the sleeves being too tight and it will be difficult to stop the bleeding after blood drawing. It is necessary to cooperate with the doctor when taking blood, especially when the child has blood drawn, and parents should help the doctor to fix the child's arm. While drawing blood and making fists, the body should be relaxed, and in order to eliminate tension, you can talk to others to distract yourself.

After the blood is drawn, the puncture site should be pressed tightly with a sterilized cotton ball for 3-5 minutes to stop the bleeding, and the upper sleeves should be relaxed. Do not rub the puncture site to avoid local bruising and "bruising". Do not touch the puncture point also after the bleeding has stopped to avoid infection.

Occasionally, some people have "fainting" phenomena after taking blood due to fasting, poor rest, mental tension and other factors: dizziness, paleness, general fatigue, and difficulty breathing. At this time, you should immediately seek help from the doctor, and at the same time, you can lie on your back in the waiting chair, release your belt, take a deep breath, and get relief in a few minutes with the help of the doctor.

People with a history of "faint needle" can bring some candy, chocolate, etc. when taking blood next time, and taking it immediately after blood drawing can avoid the occurrence of such phenomena. Finally, ask the doctor for the time and place of obtaining the test report so that you can get a timely consultation. Oh.

It depends on your technique, the amount of blood donated at a time is about 250 ml, which is a very safe amount, you smoke it yourself, affected by the technology, it may hurt for several days.

According to your situation, it is most suitable to donate blood, and it satisfies your curiosity, and the blood bank can also ensure your health and health.

If you want to draw blood, you should know the approximate location, use a well-packaged disposable syringe, and wipe the blood collection site with a 75% medical alcohol cotton ball before and after drawing. If you do both, you won't be afraid of bacteria or something.

It is best to operate the syringe and have studied health school or something, and if the technique is poor, it will be pumped on the back of the hand, the blood vessels will be easy to find, and the good skills will be pumped on the arm, and the blood vessels will be thicker. There are no too delicate nerves on the injury and arm, so feel free to smoke it. Novices either pierce the blood vessels in pairs, or they don't tie them properly, and it is normal for them to be swollen for a few days and hurt for a few days.

As long as it is not a pig operating, it will not leave a lifelong memorial to the hail.

I've got so much, let's get a little more.

After the test, the data obtained is discarded in a special collection bucket for harmless treatment.
