Blood Donation

My first Blood Donation – An event to remember.


Today, I donated  blood at “The Blood Donation Camp” organized by Guru Nanak Institute of Hotel Management, Sodpur in collaboration with National Medical College, Kolkata. Many girls of my age fear or are too lazy to donate blood. My haemoglobin level being very good as compared to other girls of my age encouraged me for the donation. It was an awesome experience for, though I am too much afraid of needles and syringes. But the feeling that my blood can save someone’s life reduced all my fear and pain! At last I did something fruitful in my life.

History of blood donation

The first recorded successful human blood transfusion was accomplished in 1818, but due to the lack of knowledge and research, it was followed by many blood transfusion failures. Some 80 years later, it was discovered that inherited differences in people’s red cells were the cause of many of the incompatibilities seen with transfusions. Four blood types were identified - A, B, AB and O. This discovery revolutionised haematology and led the way for successful blood transfusions.
During World War I, when human blood was needed for transfusions for wounded soldiers, scientists began to study how to preserve and transport blood. But it was not until World War II that the development of effective preservative solutions made blood transfusions widely and safely available. Since then, there have been many advances, such as the discovery of the Rh blood group system and technical developments such as the introduction of the plastic bag for safer blood collection.
By the end of 1947, several blood banks had been established in major cities across the United States and blood donation was promoted to the public as a way of fulfilling one’s civic responsibility.
Freezing of red blood cells, separation of different blood components by centrifugation, aphaeresis (extraction of one blood component and returning the rest to the donor) and many other discoveries and advancements make for full utilization of every donation. Each blood element can be used to treat different diseases.
Today, in light of HIV, Hepatitis C and many other diseases, the federal government has enforced regulations for blood screening tests in an effort to improve blood safety and to reduce the risk from blood transfusions. To further ensure the safety of the blood supply, the government outlawed paying someone for his or her blood.
Human blood is precious. There is no substitute for it and there is no way to manufacture it outside the body. Yet, millions of times each year, human blood is required to save the lives of people suffering from disease or who are victims of accidents.

Some Facts About Blood and Blood Donation :
1.       Someone needs blood every two seconds.
2.       About 1 in 7 people entering a hospital need blood.
3.      One pint of blood can save up to three lives.
4.      Healthy adults who are at least 18 years old, and at least 110 pounds may donate about a pint of blood—the most common form of donation—every 56 days, or every two months, depending on iron levels. Females receive 53 percent of blood transfusions; males receive 47 percent.
5.      94 percent of blood donors are registered voters.
6.      Four main red blood cell types: A, B, AB and O. Each can be positive or negative for the Rh factor. AB is the universal recipient; O negative is the universal donor of red blood cells.
7.      Dr. Karl Landsteiner first identified the major human blood groups – A, B, AB and O – in 1901.
8.      One unit of blood can be separated into several components: red blood cells, plasma, platelets and cryoprecipitate.
9.      Red blood cells carry oxygen to the body’s organs and tissues.
10.   Red blood cells live about 120 days in the circulatory system.
11.    Platelets promote blood clotting and give those with leukaemia and other cancers a chance to live.
12.    Plasma is a pale yellow mixture of water, proteins and salts.
13.   Plasma, which is 90 percent water, makes up 55 percent of blood volume.
14.   Healthy bone marrow makes a constant supply of red cells, plasma and platelets.
15.   Blood or plasma that comes from people who have been paid for it cannot be used to human transfusion.
16.   Granulocytes, a type of white blood cell, roll along blood vessel walls in search of bacteria to engulf and destroy.
17.   White cells are the body’s primary defence against infection.
18.   Aphaeresis is a special kind of blood donation that allows a donor to give specific blood components, such as platelets.
19.   42 days: how long most donated red blood cells can be stored.
20.  Five days: how long most donated platelets can be stored.
21.    One year: how long frozen plasma can be stored.
22.   Much of today’s medical care depends on a steady supply of blood from healthy donors.
23.   2.7 pints: the average whole blood and red blood cell transfusion.*
24.  Children being treated for cancer, premature infants and children having heart surgery need blood and platelets from donors of all types, especially type O.
25.   Anaemic patients need blood transfusions to increase their red blood cell levels.
26.  Cancer, transplant and trauma patients, and patients undergoing open-heart surgery may require platelet transfusions to survive.
27.   Sickle cell disease is an inherited disease that affects between 90,000 to 100,000 people in the United States, 98 percent of whom are of African descent.
28.  Many patients with severe sickle cell disease receive blood transfusions every month.
29.  A patient could be forced to pass up a lifesaving organ, if compatible blood is not available to support the transplant.
30.  Thirteen tests (11 for infectious diseases) are performed on each unit of donated blood.
31.   17 percent of non-donors cite “never thought about it” as the main reason for not giving, while 15 percent say they’re too busy.
32.   The #1 reason blood donors say they give is because they “want to help others.”
33.  Shortages of all blood types happen during the summer and winter holidays.
34.  Blood centres often run short of types O and B red blood cells.
35.  The rarest blood type is the one not on the shelf when it’s needed by a patient.
36.  There is no substitute for human blood.
37.  If all blood donors gave three times a year, blood shortages would be a rare event (The current average is about two.).
38.  46.5 gallons: amount of blood you could donate if you begin at age 17 and donate every 56 days (depending on iron levels) until you reach 79 years old.
39.  Four easy steps to donate blood: medical history, quick physical, donation and snacks.
40. The actual blood donation usually takes about 10 minutes. The entire process – from the time you sign in to the time you leave – takes about an hour.
41.   After donating blood, you replace the fluid in hours and the red blood cells within four weeks. It takes eight weeks to restore the iron lost after donating.
42.  You cannot get AIDS or any other infectious disease by donating blood.
43.  10 pints: amount of blood in the body of an average adult.
44. One unit of whole blood is roughly the equivalent of one pint.
45.  Blood makes up about 7 percent of your body’s weight.
46. A newborn baby has about one cup of blood in his body.
47.  Giving blood will not decrease your strength.
48. Any company, community organisation, place of worship or individual may contact their local community blood centre to host a blood drive.
49. People who donate blood are volunteers and are not paid for their donation.
50.  Blood donation. The entire process takes about one hour and 15 minutes; the actual donation of a pint of whole blood unit takes eight to 10 minutes. However, the time varies slightly with each person depending on several factors including the donor’s health history and attendance at the blood drive. It’s about an hour of your time. It’s About Life.
