Rejuvenate the organ before transplanting

For the first time, a damaged donor lung has been modified and grafted to patients. Normally donated lungs if not up to standard will be discarded. However, applying new techniques to combine drugs with stem cells, Canadian doctors have turned the lungs almost to be discarded into qualified lung graft for patients.

Donated lungs are usually taken from deaths from brain injury to transplant for patients. However, when the brain stops working normally releases enzymes (enzymes) that cause inflammation, only about 15% of the lungs meet the criteria for transplant surgery. Good lungs will be kept cold and can be used for transplantation within 6 to 8 hours.

With the new process, donated lungs after being separated from corpses will be transferred to the protective compartment connected to the ventilation system and the filter to be conveyed with oxygen solution. The temperature of the lungs is increased for 30 minutes until it reaches 37 ° C - at this temperature threshold, the lungs can be stored from 12-18 hours, allowing doctors to assess the quality of the organ to be treated. proper logic. During this time, the lungs also use a part of the self-regenerating ability to recover similarly to the body.

Canadian scientists think their technique can be applied to all organs, and open up the prospect of establishing an organ bank similar to a blood bank, where testing and organ donation are donated. The technique of 'sucking' this organ has been successfully tested in 4 lung transplant patients.
