Have you or someone you know ever needed to donate blood? Maybe during a major operation or in an emergency, we have to donate blood. This is what we call a Blood Transfusion. Although it may seem a little scary at first glance, this is a very important thing that is done to save lives. So let's learn everything about it today.
What happens before donating blood?
When you decide to donate blood, the doctors and nurses will first take some blood from you and find out exactly what your blood type is. This is very important. Because you want to give the blood type that is most compatible with you. But sometimes, if you need to donate blood quickly, such as in an emergency, there are times when "O negative" blood type, which can be given to everyone, is used.
In addition, you will be asked to give your informed consent before undergoing this treatment. This means that you will have to sign a document that explains what will happen, the benefits, risks, and alternatives. But imagine, in a situation like a person who is unconscious after an accident, there is no way to get this consent. In such a situation, the medical staff will try to contact your next of kin.
What happens when you donate blood?
The process of donating blood is a very delicate one. These are the steps that usually occur.
| Steps | Description |
|---|---|
| 1. Weight check | Your weight is measured to determine how much blood your body needs. |
| 2. Checking Vital Signs | Your temperature, pulse rate, and blood pressure will be checked. These will be checked several times during the blood donation. |
| 3. Putting an IV Line in the Arm | A small tube will be inserted into a vein in your arm. This tube will connect to the blood bag. You may feel a little pain when the tube is inserted. Sometimes, if you already have a central venous catheter in a large vein for another treatment, you may be given blood through that. |
| 4. Starting blood donation | First, the blood is given very slowly. This is to see if it suits your body and if there are any problems. At this time, the nurse will ask you if you have a fever, chills, or difficulty breathing. If everything is going well, the blood flow will be increased a little. |
| 5. Continue to monitor | Your vital signs will be checked again while you are donating blood. You will be asked regularly how you are feeling. If you have a serious reaction, the transfusion will be stopped immediately and treated. |
| 6. Ending with blood | When the blood bag is finished, the tube in your hand is removed. After that, your vital signs are checked and you are asked how you are feeling. |
How long will this take?
The time it takes for this to happen varies depending on the type of blood being donated.
- If you donate red blood cells or whole blood, it usually takes about two to four hours .
- If you give something like plasma or platelets, it's even faster. It can take about an hour .
What do you do when you're done donating blood?
After donating blood, the doctor will explain to you what to do if you have any allergies or other reactions. If you do not need any other treatment, you will be able to go home shortly after. You will be advised to rest for the next 48 hours .
The arm where the tube is inserted may be a little sore. Soaking it in cold water and keeping your arm elevated for a while may help.
What are the benefits of donating blood?
Simply put, donating blood can save lives.
If you have lost a lot of blood from a major surgery or a serious accident, donating blood can save your life. It is also used as a treatment for certain blood disorders and several types of cancer.
What are the risks of donating blood?
Donating blood is generally a very safe procedure. However, as with any medical procedure, there are some risks. But remember, your doctor will only recommend that you donate blood if the benefits far outweigh the risks.
These are some of the possible risks.
| Risk | What happens with this? |
|---|---|
| Allergic Reaction | Your immune system may react to some of the substances in the blood you receive from outside. You may experience minor symptoms such as skin itching and hives. Rarely, you may experience severe allergic reactions such as difficulty breathing, rapid heartbeat, and vomiting. |
| Alloimmunization | This can happen to people who receive blood frequently. Each time you receive blood, your body starts making antibodies against the new blood. As these antibodies build up, it becomes harder to find a blood match for you in the future. |
| Fever | Fever and chills can occur as your antibodies react to the white blood cells in the new blood. If your fever is accompanied by chest pain and nausea, it could be a sign of a serious condition. |
| Hemolytic Transfusion Reaction | This is rare, but very serious. This can happen if your blood type and the type of blood you receive are not exactly the same. This is when your immune system starts to destroy the red blood cells in your body. Symptoms include chest pain, fever, chills, dark urine, and back pain. |
| Post-transfusion Purpura | This is where antibodies produced in your body destroy the platelets in your blood. This can cause excessive bleeding. Symptoms such as skin bruising, bleeding gums, and nosebleeds may appear 5-12 days after donating blood. |
| Circulatory Overload | This can happen to people with heart disease or kidney disease. This condition occurs when the body cannot handle the extra fluid that comes from donating blood. Difficulty breathing and coughing are the main symptoms. |
| Blood-borne infections | This happens very rarely now, because every bag of donated blood is rigorously tested for various infections (such as HIV and hepatitis). |
If you have these symptoms, call your doctor immediately.
Reactions to blood donation can occur during the donation, the day after, or even months later. If you experience any of the following symptoms, tell your doctor right away.
- Bleeding, pain, or new bruising at the site of the tube insertion
- Cold skin, fever, or chills
- Dark or red urine
- Rapid heartbeat, chest pain, difficulty breathing
- Headache or dizziness
- Nausea or vomiting
- Skin rash, itching
- Severe back pain
- Swelling of the lips, tongue, or face
Can I refuse to have blood drawn?
Yes. As with any medical treatment, you have the right to refuse blood. In such a case, the doctor will ask you why. He will also explain to you why he is recommending this treatment and what could happen if you do not do it. This is a great opportunity for you to overcome your fears and doubts, ask questions, and feel confident in your decision.
Blood is an indispensable thing in our lives. Donating blood is a valuable medical treatment that can save someone's life. Therefore, do not have any questions or doubts about this. Ask your doctor anything and find out. Then you will have a good understanding of this process and feel at ease.
