If a person dies because of the failure of a human organ, shouldn’t replacing that organ with a perfectly working organ bring him back to life?
In the late 20th – early 21st century transplantation medicine became an area concentrating the latest achievements of surgery, anesthesiology, critical care medicine, immunology, pharmacology and other life sciences. This is an area of high biomedical technologies used in cases of pathological changes in human organs and tissues which would inevitably lead to the death of the patient (Abelson, 1991). Organ transplantation also has a great social value, because it doesn’t only extend life but can ensure high level of its quality.
Looking at the high level of medicine the answer to our question seems to be simple. But transplantation medicine faces several problems and it’s not that easy to revive the patient. First of all, there is always a chance of organ rejection. Since the donor organ doesn’t match patient’s tissue exactly, the body tries to destroy the transplanted organ by rejecting it. For example, short-term positive result of kidney transplantation is usually observed in more than 75% cases (Verma, 2003).
One day therapeutic cloning and stem cell research could provide a way to generate artificial cells or body parts that would be genetically identical to a prospective patient (Hakim, 2009), but medicine is still far from this. Scientists research the possibility of growing human body parts on mice and doing brain transplantation experiments on dogs and primates.
So organs replacement works and can help to extend person’s life, but transplantation medicine is not perfect and faces some problems. Humans are biological organisms and you can’t just replace one detail with another like it works with robots or machines.
