Two long-term comatose
patients have finally awakened in Changhai Hospital's hyperbaric oxygen
therapeutic center, hospital officials announced over the weekend.
Zhang Shifen, 30, from Jiangyin, Jiangsu Province, came to the hospital just
after the May holiday break. She was in a coma after being poisoned by hydrogen
sulfide at work.
Cai Zhongliang, 35, from Jiading, on the outskirts of Shanghai, woke up at
the end of last month after three months in coma caused by a traffic accident.
Both of them were treated with hyberbaric oxygen therapy.
"We feel overjoyed now because doctors at our local hospital said my daughter
will never wake up," said Tang Rendi, Zhang's mother.
Liu Qingle, the center's director, understands the joy and excitement but
considers the two just normal cases. "We help comatose patients regain
consciousness just like other doctors treat diseases such as colds," said Liu.
The hospital's statistics show that an average one or two patients in a
vegetative state have awakened every month since 2002, when the center's
hyperbaric oxygen therapy treatment swung into full operation.
According to Liu, their wake-ups account for more than 50 percent of
patients. "We can tell whether the patient can wake up in most cases based on
our experiences," said Liu.
Liu explained that the therapy helps cause a saturation of oxygen in the
plasma and tissue fluids so the body can function more effectively.
"Hyperbaric oxygen therapy is one of the most effective methods to wake up
people in a vegetative state," said Wang Guisong, a respected neurosurgeon at
