If I don t pull out the needle at the end of the infusion, will there be air?

When we have a cold, there are many cases of fever injections and even infusions, but many people will ask a question, that is, if you do not remove the needle after the end of the infusion, will the blood vessels enter the air? First of all, air entering the blood vessels will cause vascular embolism, which is a very serious disease in medicine, and in the most serious cases, it will directly lead to death. When experimenting with mammals such as rabbits in medical school, this method was used to stop the heartbeat of white rabbits.

So that's what we're very worried about.

In the daily process of our infusion, there is no need to worry, after the end of our infusion, because the infusion tube is transformed from liquid pressure to gas pressure, and the other end of the needle inserted in the blood vessel is liquid pressure, there is a certain pressure difference between the two, so sometimes after the infusion if the needle is not removed in time, a little blood will flow out from the needle. The back-up blood also clotted quickly. Therefore, there is a pressure difference, and we don't need to worry about this problem.

However, some special infusion methods should attract great attention, such as pressurized infusion or elevated limb infusion. When we do this type of infusion, we remove the needle before the fluid runs out. In this way, we can ensure that no air can enter our blood vessels.

In the infusion process, what we really need to pay attention to is not whether the blood vessels will enter the air after the infusion is completed, but whether the air in the infusion tube has been exhausted before the infusion, and whether there is a problem of sealing when adding liquid. These are the things we need to pay attention to when we are infusion.

The air will not enter without the needle being withdrawn at the end of the infusion, which does not require us to worry too much. However, we should always pay attention to the infusion of liquid to avoid some accidents.

It does get air, because there is actually air in the infusion bag, which may cause some harm to the human body.

It will not enter the air, but it will return blood, so it is generally no problem to look at it in time, and it is okay to pull out the needle directly when the blood returns, and it will not have any effect.

The infusion has ended, and if you don't pull it out, it will definitely enter the air, and a lot of air will enter the body with the blood vessels, which is very bad for the body.

If you don't pull out the needle at the end of the infusion, you will really get air. After all, there is no extra one, and the blood will go in, so that's it.

A small amount of air enters the body, but it does not affect because the air is metabolized by the bloodstream.

There will definitely be, and it can cause some infections in our body. It can even cause us to have a bloated stomach and not be able to eat.

I think it will, but it won't have any effect on the body because the amount of air coming in is very small.

It can cause blood vessel thrombosis and is life-threatening.

Air embolism is a dangerous complication that may occur when the air is not exhausted during infusion, the rubber tube connection is not tight, there is a leaking seam, or the pressurized infusion and blood transfusion is unattended. As soon as a small amount of air enters the vein, the patient will experience abnormal chest discomfort, followed by dyspnea, severe cyanosis, and hypoxia, which can lead to immediate death.

1.Many years ago, the tubes used for infusions were open. If a large amount of air is not injected into the blood vessels (more than 20 liters) in time, it will block blood flow and form an air embolism.

It causes acute pulmonary edema, coughing up pink frothy sputum, dyspnea, cyanosis of the lips, and is life-threatening.

2.Nowadays, the infusion strip has been changed to a closed type, and when there is no saline in the bottle, the infusion will be automatically stopped, and the blood will flow back a little from the vein into the infusion tube, thus preventing air from entering the human blood vessel.

3. Now there is no need to worry about the occurrence of air embolism in the infusion, even if there is a little air in the tube, it will generally not exceed 1 ml, do not worry, it will not cause harm, because those small bubbles will be discharged with the blood flow to the pulmonary artery orifice.

The serious consequence of the air entering the blood vessels of the human body is air embolism, that is, the air column is blocked in the small blood vessels of certain organs, resulting in obstruction of blood circulation and corresponding symptoms. However, this is only possible when the amount of air entering is relatively large, at least a few milliliters or more.

Yours only have two bubbles, in fact, it is not very rare in the infusion operation (of course, it is better to avoid), it will not cause the uncomfortable feeling you said, you can relax at this point. There is no need to deal with it.

The discomfort you are talking about may be caused by your original or other diseases, maybe the medication is injected too quickly, the concentration is too high and the hand is sore, or it may be due to the excessive nervousness caused by the entry of air bubbles. If it still exists, you can check the corresponding cause again and deal with it.

What happens when the blood vessels get air into the blood during the infusion? I feel uncomfortable after reading it!

Therefore, it does not cause damage and can disperse to the alveolar capillaries, where it binds to hemoglobin. or diffuse to the alveoli, excreted with breathing, stirring the air and blood in the heart chambers to form a large amount of foam, when the heart is contracted and not discharged or blocked by the pulmonary artery can lead to sudden death, the infusion set must be removed and the needle must be inserted again

Air enters the blood vessels. Generally, when the air that quickly enters the blood circulation is about 100 ml, it can cause gas embolism, and the air will not enter If you still have to continue the infusion, you will die in severe cases But this will not happen during the infusion, because the blood is under pressure in the blood vessels, and the blood will flow into the infusion tube. However, the amount of air entering the blood is large and relatively rapid, and the air is injected into the blood vessels due to the beating of the heart.

If the amount of air is small, it can cause shock, but it depends on the amount of gas entered.

There should be no danger during the infusion, because the human body has blood pressure, but if you want to squeeze air into the blood vessels, then it is a different matter.

If air is injected into the blood vessels, it will cause shock, and in severe cases, death will not happen But this will not happen during the infusion, because the blood is under pressure in the blood vessels, and the blood will flow into the infusion tube, and the air will not enter If the infusion must be continued, the infusion set must be removed and the needle inserted again

Air entering blood vessels can cause gas embolism, depending on the amount of gas entered. If the amount of air is small, it can be dispersed into the alveolar capillaries and bind to hemoglobin. or diffuse into the alveoli and excrete with respiration without causing damage.

However, if the amount of air entering is large and relatively rapid, due to the beating of the heart, the air and the blood in the heart chambers are stirred to form a large amount of foam, and when the heart is contracted, it is not expelled or the pulmonary artery is blocked, which can lead to sudden death. Generally, when the air that quickly enters the blood circulation is about 100 ml, it can lead to heart failure, which is manifested as an abnormal feeling in the chest, followed by dyspnea and cyanosis, and then immediately organize rescue.
