Blood Donation and its Importance (Practical )

Blood Donation and its Importance ( Practical 
History
The earliest documentation of blood transfusion is found in the religious text of many civilizations. The first documented demonstration of blood transfusion was between two dogs by Richard Lower in 1665.
Landsteener discovered the ABO Blood Group system in 1901, which is one of the most important landmark discoveries in the Transfusion Medicine. In the 1970s voluntary donors were accepted as blood donors. These donors were later on found to people having high-risk activities and the recipients were found to be suffering from liver diseases. This lead to another discovery of Hepatitis B transmitted by donated blood. Since then testing for the hepatitis B antigen was implemented and this together with cessation of paid donors reduced the incidence of post transfusion hepatitis. Further studies also made us to include tests for Malaria, Syphilis, AIDS, and Hepatitis C to make the donated blood as safe as possible to the recipient.
What is blood?
One can almost say that blood is that magic potion which gives life to another person. Though we have made tremendous discoveries and inventions in Science we are not yet able to make the magic potion called Blood. Human blood has no substitute. Requirement of safe blood is increasing and regular voluntary blood donations are vital for blood transfusion services.

Who can donate blood?

Eligibility criteria for blood donation
Donor should be between 18-55 years of age with a weight of 50 kg or above with pulse rate, body temperature and blood pressure should be normal. Both men and women can donate. There are only few conditions in which donors are permanently excluded. The donor with history of epilepsy, psychotic disorders, abnormal bleeding tendencies, severe asthma, cardiovascular disorders, malignancy are permanently unfit for blood donation. Donors suffering from disease like hepatitis, malaria, measles, mumps, and syphilis may donate blood after full recovery with 3-6 months gap. Also people who have undergone surgery, blood transfusion may safely donate blood after 6-12 mths for woman donors who are pregnant or lactating blood is not taken as their iron reserves are already on the lower side.
How much blood can be taken?
Our body has 5.5 ltr of blood of which only 350 ml - 450 ml of blood is taken depending upon weight of donor. Majority of healthy adults can tolerate withdrawal of one unit of blood. The withdrawn blood volume is restored within 24 hours and the hemoglobin and cell components are restored in 2 months. Therefore it is safe to donate blood every three months.

What is done with the blood collected?
The blood collected in sterile, pyrogen free containers with anticoagulants like CPDA or CPDA with SAGM. This prevents clotting and provides nutrition for the cells. This blood is stored at 2-6 C or -20 C depending on the component prepared. Donated blood undergoes various tests like blood grouping antibody detection, testing of infections like hepatitis, AIDS, Malaria, syphilis and before it reaches the recipient it undergoes compatibility testing with the recipient blood.

Modern Blood Transfusion Practice:

Modern blood transfusion basically deals with the optimal use of one unit of blood. One unit of whole blood is separated into components making it available to different patients according to their requirement. Thus one unit of blood is converted into packed cell volume, fresh frozen plasma, platelet concentrate, cryoprecipitate and granulocytes concentrate.

Another important practice is apheresis. This is separation of only desired component from the donor and return the remaining constituent back to donor. This technique is also used for remaining pathological substance in patients.

Withdrawal of blood for transfusion is regarded as a safe procedure now and blood donor has emerged as the single most vital link.

IT IS NOT A STORY BUT A TRUE INCIDENT THAT HAPPENED IN AMERICA .....

A Indian man walks into a bank in New York City and asks for the loan officer. He tells the loan officer that he is going to Indian on business for two weeks and needs to borrow $5,000.

The bank officer tells him that the bank will need some form of security for the loan, so the Indian man hands over the keys of a new Ferrari parked on the street in front of the bank. He produces the title and everything checks out. The loan officer agrees to accept the car as collateral for the loan.

The bank's president and its officers all enjoy a good laugh at the Indian for using a $250,000 Ferrari as collateral against a $5,000 loan. An employee of the bank then drives the Ferrari into the banks underground garage and parks it there.

Two weeks later, the Indian returns, repays the $5,000 and the interest, which comes to $15.41.The loan officer says, "Sir, we are very happy to have had your business and this transaction has worked out very nicely, but we are a little puzzled. While you were away, we checked you out and found that you are a multi millionaire. What puzzles us is, why would you bother to borrow "$5,000" .

The Indian replies: "Where else in New York City can I park my car for two weeks for only $15.41 and expect it to be there when I return'"

Ah, the mind of the Indians.. .....

Farmer's Daughter - A Good Story

A young man wished to marry the farmer’s beautiful daughter. He went to the farmer to ask his permission.

The farmer looked him over and said,

“Son, go stand out in that field. I’m going to release three bulls, one at a time. If you can catch the tail of any one of the three bulls, you can marry my daughter.”

The young man stood in the pasture awaiting the first bull.

The barn door opened and out ran the biggest, meanest-looking bull he had ever seen. He decided that one of the next bulls had to be a better choice than this one, so he ran over to the side and let the bull pass through the pasture out the back gate.

The barn door opened again. Unbelievable. He had never seen anything so big and fierce in his life. It stood pawing the ground, grunting, slinging slobber as it eyed him. Whatever the next bull was like, it had to be a better choice than this one. He ran to the fence and let the bull pass through the pasture, out the back gate.

The door opened a third time. A smile came across his face. This was the weakest, scrawniest little bull he had ever seen. This one was his bull. As the bull came running by, he positioned himself just right and jumped at just the exact moment.

He grabbed… but the bull had no tail!

Moral: Life is full of opportunities. Some will be easy to take advantage of, some will be difficult. But once we let them pass (often in hopes of something better), those opportunities may never again be available. So always grab the first opportunity.
