A 9-day-old infant died but before she passed away she donated her kidneys, saving another child’s life, in Kunming, capital of Southwest China’s Yunnan Province, on July 26, Kunming-based City Times reported.
The report said the infant donor became the youngest donor in the province’s history.
The infant’s mother, surnamed Zuo, suffered from placental abruption and gave birth to the female baby on July 17.
The newborn had severe asphyxia and was in deep coma. Despite rescue efforts, she was diagnosed as brain dead on the seventh day of her birth.
Parents decide to donate the baby’s organs
She was the second child of her family. Her parents were looking forward to her birth. Her grieving father asked whether the baby can leave something in this world.
“Though my child had a short life, I hope her organs can save other children’s life,” said the father. “If so, I and her mother will be grateful.”
Entrusted by the infant’s mother, the father signed documents to permit the donation.
“The family experienced such a blow but thought to help others. We are deeply moved,” said Li Ke, a staff member of the Red Cross Society of China, who witnessed the signing ceremony.
The organ harvest operation is difficult
After an evaluation, the infant’s kidneys were deemed qualified to be donated. The infant was sent to the operation room for kidney harvest at 10 am of July 26.
Medical staff removed the respirator from the infant after a moment of silence. Her heart stopped beating.
“The newborn’s organs were very small. Her blood vessel and ureter were very thin,” said Zhao Yongheng, the surgeon, adding that the thin blood vessels are easy to snap.
If the vessel breaks, the organ will be useless, Zhao said. Eventually, the operation harvested two kidneys.
An 8-month-old receives a kidney
Two kidneys were assigned to two patients in Wuhan, Central China’s Hubei Province, via China Organ Transplant Response System and were transferred right after they were harvested.
One kidney was too small to be transplanted to the potential receiver.
Another kidney was transplanted to an 8-month-old patient. “The kidney matched the patient well and started to play its role,” said surgeon Zhao Yongheng,
China banned transplants of organs from executed prisoners in January 2015, so voluntary donations have been the only source of organs since then.
Data from China Organ Transplant Response System show that since China launched the system in 2010, about 10,000 people have donated vital organs upon their death as of the end of 2016.

Chinese workers are building the world’s deepest and Asia’s largest underground high-speed railway station beneath the Great Wall at the Badaling section in Beijing. The station under construction will be 3-story high and have a 36,000 square meters floor area, including platform, entrance and exit. The railway tracks will be 102 meters underground.
The station is an important part of a 12.01 kilometers long tunnel section of the 174-kilometer Beijing–Zhangjiakou high-speed railway line. The tunnel is the longest one of the railway line.
“Passengers will enter and exit the station about 100 meters underground, and it will be very safe,” said Dai Longzhen, a senior manager of the construction company China Railway No 5 Engineering Group Co Ltd.
An escalator would raise passengers 62 meters at vertical height, and inclined elevators will also be used in the station for the first time.
To secure the safety of passengers, the station will change the inclined shafts that are used to build the station as permanent rescue channels.
The underground burrowing work is the country’s most complicated, because the station has to contain 78 caverns and lots of intersections, said Chen Bin, a commander-in-chief of the project.
Starting from the construction of the tunnel on April 15, 2016, workers have known how tough the work will be, however the hardness of the rocks still exceeded their expectations, said Jiang Si, a manager of the company.
According to its initial plan, workers could excavate the tunnel 6 to 8 meters a day, but the tough rock meant workers could dig only about 2 meters a day.
Large–size shield tunneling machines could not be used, and workers could only use the blasting method in the construction, Dai said.
“The No 1 shaft has a 80-degree turn, and the No 2 shaft has a 135-degree turn, which prohibits the machines more than 100 meters long from working there,” Dai said.
Workers have to develop new blasting technology to explore the tunnel carefully, because just above it are the Great Wall and the railway line linking Beijing and Zhangjiakou first independently designed and built by Chinese 100 years ago.
Workers have carried out more than 4,500 explosions. They use the electronic detonators to control the vibrations in batches of small explosions to reduce the impacts on the inside of hills and the Great Wall. At the Qinglongqiao station of old Beijing-Zhangjiakou railway line, worker used expansive agents to dig the tunnel, only 4 meters beneath.
Another problem in the tunneling is the underground water, and every day, workers have to pump at least 19,000 cubic meters of water, which equals about 10 swimming pools.
The Bejing-Zhangjiakou high-speed railway is expected to get through by the end of 2019, allowing passengers to travel between the two cities in one hour. It is an important project for the 2022 Winter Olympic Games.
