doctors save boy by \'printing\' an airway tube with 3d printer
This is the latest development in the booming field of regenerative medicine, manufacturing body parts in the laboratory.
Girl born without a trachea got a bio
In the case of Kaiba Gionfriddo, the doctor did not have the extra time.
Due to birth defects, the little Ohio boy\'s airways collapsed continuously, causing breathing to stop and the heart to collapse frequently.
Doctors in Michigan have been working on artificial airway splints, but have not yet been implanted in patients.
In one day, they \"printed\" 100 test tubes on their computer.
The guide laser stacks and blends plastic films instead of paper and ink to form a variety of shapes and sizes.
The next day, under the special permission of the Food and Drug Administration, they implanted one of the tubes in Kaiba, the first time they did so.
All of a sudden, a doctor said the baby who might not be alive leaving the hospital could breathe normally for the first time.
He was only three months old at the time of surgery last year and is now almost 19 months old.
He is going to take down the tube cut through the trachea.
When he was a few months old, it was put there and needed a ventilator.
He hasn\'t had a breathing crisis since he came home a year ago.
\"He is a very healthy child now . \"
Glen Green, an expert in pediatric otolaryngologyS.
The location of the operation is the University of Michigan Mott Children\'s Hospital in Ann Arbor.
The New England Journal of Medicine on Thursday described it.
The independent expert praised the work and potential of 3D printing to create more body parts to address unmet medical needs.
\"This is the wave of the future . \"
Robert Witherley is a pediatric specialist at the University of Missouri in Kansas City.
\"I was impressed by their achievements.
\"So far, only a small number of adults have had a trachea or trachea transplant, usually to replace the trachea damaged by cancer.
These cartridges come from the dead donor or the lab.
Stem cells are sometimes used for manufacturing.
Last month, a 2-year-
The old girl, who was not born with a trachea, received a stem cell from her own stem cell growth to a plastic scaffold at the Peoria hospital.
There\'s a different problem with Keba.
An incomplete trachea, one of the two Airways that branch from the trachea, extends like a trouser leg to the lungs.
In the United States, about 2,000 babies are born with this defect every year, and as more organizations develop, most babies grow up at the age of 2 or 3.
In severe cases, parents will learn about the defect when the child suddenly stops breathing and dies.
When Keba and his parents were 6 weeks old in a restaurant in April, it almost happened, with Brian gunfrido living in Youngstown, Northeast Ohio.
On April, Gionfriddo said: \"He turned blue and stopped breathing on us . \" His father performed CPR to restore his life.
More incidents followed, and when he was 2 months old, Kaiba had to use a ventilator.
The doctor told the couple that he was in serious condition.
\"A lot of people say there is a good chance he won\'t leave the hospital alive.
\"It\'s terrible,\" his mother said . \".
\"We pray every night and hope he can get through it.
\"Subsequently, Mark Nelson, a doctor at the Akron Children\'s Hospital, suggested doing the experiment in Michigan.
Researchers there are testing air-Channel splints made of biodegradable polyester, which are sometimes used to repair bones and cartilage.
Kaiba underwent surgery on February. 9, 2012.
The splints are placed around his defective trachea, which is stitched to the splints to prevent it from collapsing.
The splint has a crack along its length so that it can expand and grow like a child --
A permanent artificial implant is not possible.
Scott Hollister, a biomedical engineer who led the work, said the plastic was designed to degrade within three years and gradually be absorbed by the body as a form of healthy tissue to replace it.
Green and Scott Hollister are applying for a patent for the device, and Hollister has financial benefits for a company that makes implant brackets. Dr.
John bent, a pediatric expert at the Albert Einstein School of Medicine in New York, said that only time can prove whether this is a permanent solution, but he praised the researchers for their insistence on developing it.
\"What I can think of is that in the last 20 years, several of the children I \'ve seen have suffered a lot. . .
This could benefit from the technology, \"Bent said.
