Frequently Asked Questions
1. Where does donor blood come from?
Blood that is used in a transfusion comes from people you who have donated their blood voluntarily. If you are planning for a surgery, you may also be able to store your own blood ahead of time (autologous donation).
2. Is the blood I received from a donor safe?
In Apollo Hospitals Bangalore, donors are never paid for their blood and all the blood supply is received by voluntary donation. All prospective donors are carefully screened to protect both the person who donates the blood and the patient who receives it. Every time they donate, donors are asked a series of questions about their health. Based on these questions, some donors are eliminated from giving because they may be at greater risk of passing on an infectious disease.
A new sterile disposable needle attached to a collection bag is used to take blood from the donor. Then, every donation is tested for diseases that might be transmitted by blood transfusion. Electro Chemilumicense (ECI) is the method used for screening donor samples which is more advanced than the ELISA. Any donated blood that does not pass the test is destroyed. However, there is still a small risk of disease transmission. To put this in perspective, the risk is generally much smaller than the risk involved with most surgical procedures themselves.
3. I have surgery coming up. Can my relative donate blood for me?
A donation from a relative or friend specified for a certain patient is called a “direct donation”. Encouraging your friends and family to donate blood will help ensure that the blood supply is sufficient to prevent blood shortages.
4. I have surgery coming up. Can my own blood be stored and used?
In some circumstances, you may be able to have your own blood taken and stored prior to surgery in which a transfusion may be necessary. This is known as autologous (aw-tol-o-gus) donation. An autologous donation will not be taken if it is unlikely that a transfusion will be required. You also need to be in acceptable physical condition and have an adequate red blood cell (haemoglobin) level. Please speak to your doctor about this program. If there is not enough of your own blood available at the time of surgery, you may still need to have a transfusion of volunteer donor blood.
5. What are the risks of a blood transfusion?
6. What are the risks of not having a transfusion?
When your body has lost so many red blood cells that your body is not getting enough oxygen, you run the risk of damaging vital organs such as the brain or heart. Transfusion may be necessary to prevent such damage, which can cause serious injury, permanent handicap or death. Your physician/surgeon or anaesthetist will recommend when transfusion is needed based on your individual case.
7. What is Autologous Blood?
This is your own blood that is stored in a refrigerator and used for transfusion, if necessary, at the time of surgery.
Advantages of Using Your Own Blood
- You have no risk of being infected by contaminated blood.
- You will not become immune to other blood types. When you receive blood from someone else, you may become immune to other blood types leading to risks or difficulties in future transfusions if required.
- You won’t have possible allergic or other immune reactions.
- Possibility of a slightly lower risk of complications after surgery if your own blood is used.
8. Who is eligible?
Most people who plan to have major elective surgery are eligible. The medical staff at the Blood Conservation Program will determine your eligibility based on
- General medical condition.
- The procedure you are schedule to have.
- The amount of blood usually required for the procedure.
9. What do I do?
At the pre-admission unit, a staff person will review the autologous blood donation process with you and answer any questions you may have. An anaesthetist will check to see if you are medically and physically fit to donate. A request for your donation will be forwarded to the Apollo hospitals blood bank and you will be contacted to set-up a donation. The required amount of blood will be collected at a series of appointments about a week apart.
10. Where is my blood stored?
The blood will be stored at the Apollo Hospital blood bank. If your blood is not used, or it expires, it will be properly disposed of.
11. What if I require more blood than I can donate?
If more blood is required than what is donated, donor blood from the Apollo hospital blood bank will be used.
12. Are there any disadvantages to being an autologous donor?
You may find that coming in for each donation session is inconvenient. Pre-donation testing, the actual donation and post-donation recovery may take one to two hours or more per donation.
13. Are there any side effects to donating blood?
There are minor side effects such as bruising or bleeding from the needle, light-headedness, fainting or dizziness, and mild anaemia. Severe complications can include low or high blood pressure, abnormal heart rhythm or rate, chest pains, heart attack or stroke.
Diet and Iron
Iron is a mineral that is essential for forming part of haemoglobin (red blood cells) which carries oxygen to the cells of the body. Oxygen is important for your body’s cells to grow and function.
14. What happens if you do not get enough iron?
If the levels of iron in your body are low you may experience
- a feeling of being tired.
- lack of energy.
- pale skin.
- problem concentrating.
- signs of irritability
- difficulty breathing
15. Why do you need a lot of iron before surgery?
- Your body needs iron to help build new red blood cells.
- An increase in red blood cells will be needed before surgery to allow you to participate in some parts of the blood conservation program (donation of your own blood).
- A higher red blood cell level will allow oxygen to get to body cells and help you recover faster from your surgery.
- It also provides an adequate amount of red blood cells in case there is bleeding during or following your surgery.
16. What foods should you eat?
Iron can be found in a variety of foods. There are two types of iron in foods: Heme and Non-Heme irons.
It is easily absorbed by the body and is found in foods such as organ meats (liver, kidney, heart), beef, lamb, pork, veal, poultry (dark meat), and fish or seafood.
It is not as easily absorbed and is found in foods such as whole grain cereals or fortified cereals, vegetables (beans, lentils, dried peas, chard), dried fruits (raisins, apricots), seeds and nuts, breads and pasta that are whole grain or enriched.
17. How can you get the most iron from the food you eat?
When you eat Non-Heme iron, you should include foods that help to increase iron absorption. Foods containing vitamin C, such as fruit (strawberries, kiwi, oranges, and raspberries), fruit juices, cauliflower, broccoli, brussels sprouts, tomatoes, turnip, and foods containing Heme irons, will help in the absorption of the Non-Haeme iron, when eaten at the same time.
Some combinations can include
- iron fortified cereal with orange juice.
- whole grain toast and strawberries
- egg salad and fruit.
- mutton with beans.
NOTE: You should avoid tea, coffee, caffeine soft drinks, cocoa and milk (calcium) with your meals because they lower the amount of iron that is absorbed. Have these drinks in between meals.
