Organ Donation | DoctorNDTV ... for the better health of Indians

Organ Donation

In 1994, the Government of India passed the Transplantation of Human Organs Act that legalized the concept of brain death and, for the first time, facilitated organ procurement from heart beating, brain dead donors. However, this concept has not caught on well in India for want of public education and awareness. This in turn is perpetuating the commercial sale of human organs due to the widening gap between the demand and supply. Thousands of lives are lost in India annually from heart and liver failure since transplantation of unpaired organs like heart, liver and pancreas is either difficult or impossible from living donors. This is only possible on a large scale if these organs are available from cadaver donors.

What is organ and tissue donation?

Organ and tissue donation is a way to help others, after your death by allowing organs or tissues to be taken from your body and transplanted in someone else’s body. It may save another person’s life. Organ and tissue donation is a way of “giving something back” to society. It costs nothing, it does not change your own life, and it can mean a huge improvement to others’ lives. Organ and tissue donation is completely your choice.

Why should you donate your organs and tissues?

Organ failure can strike anybody at any time as a result of illness or infection. For most people who experience organ failure, a transplant is their only realistic treatment option. If you die, your organs could help several people through organ transplants and many others through tissue grafts. For e.g. your liver could save the life of someone whose liver has been damaged through illness or accident. A person who is attached to a dialysis machine could return to full-time work after receiving one kidney. Every effort is made to save your life before donation is considered and donation does not disfigure the body.

Who can become a donor?

All individuals can indicate their intent to donate. Medical suitability for donation is determined at the time of death. There are no age limitations on who can donate. The deciding factor on whether a person can donate is the person’s physical condition, not the person’s age. Newborns as well as senior citizens have been organ donors. In persons under 18 years of age the parents or guardian must consent.

How to become an organ and tissue donor?

  1. Indicate your intent to be an organ and tissue donor on your driver’s license.
  2. Carry a organ donor card.
  3. Most important, discuss your decision with family members and loved ones. Even if you sign a donor card, it is essential that your family knows your wishes. Your family may be asked to sign a consent form in order for your donation to occur.

What can be donated?
  • Organs: heart, kidneys, pancreas, lungs, liver, and intestines
  • Tissues: currently transplanted human tissues include bone, corneas, skin, heart valves, veins, cartilage and other connective tissues.
  • Bone marrow
When are organs donated?
  • Organ donation is only possible after death has occurred.
  • Following the consent of your family, the entire organ retrieval can take several hours. Blood testing and tissue typing also needs to take place before the procedure.
  • Families of organ donors are kept informed at every step. It is ensured that the retrieval procedure is over as soon as possible and causes as little disruption as possible.

Where and how does organ and tissue donation take place?

Organ donation always occurs in a hospital operating theatre, after death has been declared and the family has given consent. The incision is covered with a dressing, as in all surgical procedures. The body is treated with respect and dignity, and the family can view and spend time with the deceased afterwards. Normal funeral and burial arrangements can proceed. If a person dies in a hospital or nursing home, the family may be asked whether they wanted to donate tissues. If the death occurs elsewhere, the family should let the attending doctor know if this is what the deceased person wanted. This should be done as soon as possible after the death.

If the family consents to organ donation then the life-support machines will remain switched on. This will protect the organs for transplantation. The hospital staff may continue administering drugs to the deceased person in order to stabilise the organs. Without these drugs and a supply of oxygen, the organs would deteriorate rapidly and transplantation would not be possible. Surgery commences soon afterwards and may take several hours. Immediately before the organs are removed from the body, all mechanical ventilation is ceased and the heart is stopped. Once removed the organs are flushed with preservation fluid and specially packed in a cool chamber. They are then transported to the hospitals where they will be transplanted.

Can organs be sold?

The National Organ Transplant Act makes it illegal to sell human organs and tissues. Violators are subject to fines and imprisonment. Buying and selling of organs might lead to inequitable access to donor organs with the wealthy having an unfair advantage.

How are organs distributed?

Patients are matched to organs based on a number of factors including blood and tissue typing, medical urgency, time on the waiting list, and geographical location.
