A new technique called supercooling to preserve organs discovered

US researchers are claiming that they have discovered a new technique which will allow them to preserve organs for many days before finally transplanting them.
The technique is called ‘supercooling’. This technique collaborates chilling of the organs with pumping of nutrients and oxygen into the blood vessels of the organ. The tests performed on animals showed that the supercooled livers remained viable for as much as three days, compared to the 24 hours time available with current technology, according to the journal of Natural Medicine.
According to researchers if it works on human organs, then it has the massive potential to transform the organ donation scenario. When an organ is removed from the body, the individual cells start to die; however, cooling tends to slow down this process as it helps to decrease the metabolic rate of the cells.
In the month of March last year, surgeons in UK had carried out the first ‘warm liver’ transplant operation. This surgery used an organ which was maintained at a body temperature in a machine.
In this technique the organs are hooked first to a machine which perfuses it with nutrients and then it is cooled to minus 6 degree C.
During experiments performed on rat livers, these organs could be preserved for three days. According to one of the researchers, this technique would lead to better donor matching and would decrease long term organ rejection and other complication issues.
