There's No Such Thing As Cold

You've felt cold before. Sometimes it's cold outside. But what if I told you that "cold" isn't real? There's no substance or quantity called "cold" in science. We can't measure the amount of "cold" in something. Instead it's about what's NOT there.

The Pioneers

Many clinical trials target the nation's most acute health issues. With deaths from liver disease soaring by 40 per cent in a decade, more and more patients are waiting for vital liver transplants. There is a shortage of organ donors and many donated organs are rejected as only those in excellent condition are considered suitable for a transplant procedure. Surgeons Richard Laing and Thamara Perera are part of a team at QEHB trialling a revolutionary way to tackle this crisis, by maximising the number of donor organs that can be safely re-used. The film follows the trial every step of the way, as Richard receives a donor liver that would usually be rejected and tries to prove it is viable for transplant by rejuvenating and testing it on a perfusion machine. This machine sustains the liver by mimicking the supply of blood, oxygen and nutrients an organ receives inside a live, healthy human body. Once the donor liver has proved itself fit for transplant, the surgical team start to remove grandmother Connie O'Driscoll's severely diseased liver. Once the donor liver has been disconnected from the perfusion machine, they have just 20 minutes to place it in Connie's body and plumb it into the complex and delicate network of hepatic blood vessels.
