Beijing time on August 6, according tomedia reports, someone in the death, if the body organ donation, can save the lives of others, but in the process how doctors save the donor’s organs, and transport it? “To be an organ donor, you have to be hospitalized, use a ventilator to support your life, and some types of nerve damage may occur during the transplant process,” said Heather Meksa, chief executive of Lifebanc, an organ donor in northeastern Ohio. “
Organ donors die in two ways: brain death and heart-borne death, which can occur in different parts of the brain if the patient’s brain is severely damaged and cannot be fully recovered. Donors may have only a small amount of brain function, but doctors believe they can’t recover permanently, when they can only rely on a ventilator to survive, and eventually relatives choose to stop the ventilator to end the patient’s pain, which is considered dead when the person’s heart stops beating.
According to a study published in the British Medical Journal in 2020, most organ donors are brain-killed, with no brain function before death and irreversible loss of function in all regions of the brain, including the brain stem. When a patient is in a coma, there is no brain stem reflex, and the doctor does not pass a apnea test that shows whether all brain stem function is lost, the doctor will say it is “brain death.” Patients are legally considered dead by brain death, even if they are still on life-support using a ventilator, and their death is determined by a physician, not by an organ transplant team.
When the donor’s body is maintained through a life support system, the organ transplant team tests whether the donated organ is safely transplanted. If a donor has cancer or is infected with the new coronavirus, their organs may not be used, but not all diseases affect organ transplantation. For example, HIV-positive people can donate to HIV-positive people, Meksa stressed, we regularly perform A, B, C-positive hepatitis A and C-positive organ transplants.
Routine blood tests can show the health of organs such as the liver and kidneys, and organ transplant teams sometimes insert a thin tube into the donor’s artery or vein and then pass through blood vessels to the heart to check the donor’s heart for damage or obstruction. The team also used chest X-rays to assess lung size, infection, or signs of disease. They can perform the next test by inserting a thin tube into the lungs to assess the infection and determine if antibiotics are needed. The donor’s brain tissue cannot be transplanted, but in a state of brain death, all other organs of the body can be donated for transplant. However, according to a new study, heart tissue may be so damaged in the event of heart death that it cannot be transplanted to other patients.
After testing these organs, the organ transplant team finds a donor matching the donor from the National Transplant Organ Waiting List, and the donor’s surgeon arranges time to meet the donor and then arrives in the donor’s area. “Depending on the number of organs donated, organ donors in 3-4 states are contacted by the recipient’s doctor,” Meksa said. “
In a state of brain death, doctors stop the ventilator from pumping blood throughout the body to restore organ operation by cutting off the respiratory circulation system. For heart dead patients, they take off their ventilators and wait until the heart stops beating, which can take about half an hour to two hours, and then wait another five minutes to ensure the donor’s heart doesn’t beat, Meksa said. If the heart stops beating for too long and other organs begin to die, the surgeon may decide not to restore the organs, and for both types of organ donors, the surgeon will drain the blood from the donor’s organs, re-inject it with cryogenic preservation fluid, and then remove the organ tissue.
Surgeons airliftthe the donated organs to the recipient and begin the transplant. They must act quickly, according to the Health Resources and Services Authority (HRSA), the heart and lungs can survive 4-6 hours in vitro, the pancreas can survive 12-24 hours, the liver can survive 24 hours, and the kidneys can survive 48-72 hours. When the donor’s organ tissue is removed, relatives may prepare for a funeral and memorial service.
Organ donation can save a patient’s life, but the number of donations is not enough. According to statistics, 20 people die every day in the United States from the inability to obtain transplanted organs. Although 90 percent of adults in the United States support posthumous organ transplants, only 60 percent of adults are registered donors. Even registered donors may have problems in the donation process if they do not explicitly express their willingness to donate to their families. “When we meet with some donor families, the biggest challenge is not knowing what they want to do, after all, organ transplants are a sad, evasive thing for relatives,” Meksa said. “(Leaf Town)
