A new machine developed by the Sahlgrenska University Hospital researchers may contribute to more lung transplants in the long term.
Built by a company in Lund, the machine is used to assess and treat the function of donors' lungs before transplantation. While the lungs of many donors are of good quality, some can swell on account of the fluid that gathers in them, rendering them unsuitable for transplantation.
"The new machine allows us to get rid of the swelling and so make them fully functional," explains G'ran Dellgren, docent at the Sahlgrenska Academy and consultant in cardiothoracic surgery at Sahlgrenska University Hospital.
The lungs taken from the donor are first cooled as all donor lungs are at the donor hospital. On arrival at the transplant center the donor lungs are hooked up to the machine. After being slowly re-warmed they are then ventilated so that they can be assessed. If, after three to four hours' treatment they are in good condition, they are cooled once more before transplantation.
Four people have been given lungs treated in this way.
"We wouldn't have been able to use any of these lungs for transplantation before the machine became available," says Dellgren. "The patients now have fully functional lungs and are doing very well so far".
The almost 150 multi-organ donors in Sweden each year enable 50-60 lung transplants to be carried out. Acquired with research funding, the machine at Sahlgrenska University Hospital is an excellent tool for ensuring more lung transplants, believes Dellgren.
"We may be able to increase the number of transplants by 20-30%, which would be a blessing for all seriously ill lung patients in Sweden."
