The team at the medical center gave the same answer - lungs!
There are many capillaries at the ends of the pulmonary arteries and veins, which is the fundamental reason why the human body can quickly exchange oxygen.
But it is a pity that Li Dingsheng's lung condition has deteriorated.
The entire lung had to be removed, so it was impossible for Chen Xiao to find a solution on the capillaries in the lungs.
In addition to the lungs, some tissues of the body are also rich in capillaries - such as the liver, kidneys, large intestine, etc.
The liver metabolizes faster and is rich in chemical substances.
Not a good place for colonies to live.
Although the capillaries of the kidneys are relatively abundant, their surface area is small, and tampering with them is likely to affect kidney function.
If kidney failure occurs, the gain outweighs the loss.
Finally, after detailed discussion by the medical team, it was unanimously decided to arrange the arrangements in two places.
One is the large intestine.
The human intestine is already home to many microorganisms, so it makes sense to use a section of the large intestine for the cultivation of improved Rhodospirillum and cyanobacteria.
In addition to the large intestine, there is another place you can choose, which is the scalp layer.
The scalp is located relatively close to the heart, has a relatively large area and rich capillaries, and is also an easy place to operate.
Finally, this plan was finalized, and colonies were distributed in the large intestine and scalp.
And set up and install two small electric pumps at two locations to supply electrons to the colony in turn.
This kind of treatment by the medical team is just an attempt. No one, including Chen Xiao, knows what the final result will be.
Li Dingsheng's condition was already very bad. His blood oxygen saturation was seriously low and his heart rate was increasing rapidly.
This is a sign before death.
Treatment begins immediately.
There is no ECMO in this era, so we can only save Li Dingsheng's lungs first and race against time.
Chen Xiao and the entire medical team walked into the operating room.
Just leave professional matters to professionals.
After all, Chen Xiao was not a professional surgical expert, so all operations were left to the medical team.
He looked at Li Dingsheng's vital sign equipment and knew that the success of the operation depended on it.
Li Dingsheng's family members were waiting anxiously outside the operating room. In the era when paparazzi were still popular, many Western reporters had been waiting at the door of the Xia Guosi Academy of Sciences.
The press releases in the hands of these reporters have already been written.
"The death of a master physicist makes Xia's scientific research environment worrying."
…
The operation was performed by Wu Yong himself. He was once the best brain surgeon and had performed the most meticulous operations. Of course, he was able to perform these operations with ease.
But he was also very nervous at this time, looking at the vital sign monitor while operating.
Wu Jun knew he was racing against time.
"Blood oxygen saturation 80%..."
In addition to the vital signs that kept sounding the alarm, the surgical nurse also kept an eye on the vital signs and kept reporting them.
"75%..."
"70%!"
The nurse was already sweating profusely.
The normal experimental protective concentration of the human body should be above 94%.
If it is lower than 94%, there will be some hypoxia. If it is lower than 80%, it will be severe respiratory failure, which may be life-threatening at any time.
If it is less than 70%, then even if the patient has a chance to be saved, the brain is likely to die due to long-term lack of oxygen.
When they learned that the blood oxygen saturation had reached 70%, many people in the operating room were already in despair.
They were always prepared for the signal that Li Dingsheng's heart would stop.
At this time, Wu Yong completed the head surgery.
The bacterial colonies have covered the corresponding capillary end positions.
Chen Xiao quickly said: "Inject culture fluid!"
Only by injecting the culture medium prepared in the laboratory can the bacterial colonies be stimulated in a very short time and start working as soon as possible.
Tens of seconds later, a miracle happened.
Li Dingsheng's blood oxygen saturation was stable at around 75%, with no further decline.
"80%!"
"85%!"
"90%!"
The nurse during the operation read the numbers on the vital sign meter excitedly and felt very unbelievable.
Wu Jun's medical team is all elite.
Although their reputation is not as good as that of 301 Hospital, they have experienced rescue and treatment of various critical illnesses.
In the treatment of advanced lung cancer.
Like other hospitals, no case has been successful.
But can a miracle happen today?
But everyone was not happy for long.
Li Dingsheng's blood oxygen saturation instantly dropped to 85%.
This shows that relying solely on the oxygen produced by the metabolism of bacterial colonies in this position of the head cannot stabilize the patient's demand for oxygen.
Colon surgery is in progress.
The medical team used a 45-centimeter-long large intestine to provide a specialized growth environment for bacterial colonies.
These locations will eliminate the original lactobacilli, bifidobacteria, etc. in the large intestine.
Although the digestive function will definitely weaken and decline after surgery, it is worth the effort compared to surviving.
The surgeon also made a hole in Li Dingsheng's abdominal cavity, which was used to check bacterial colonies and infuse culture fluid.
This kind of surgery is the first time for everyone in the operating room, so the surgical process and the plan adopted may not be perfect and optimized, but as long as it can save lives, many of the flaws of the surgery can be ignored.
.
The operation had reached the fifth hour, and when the bacteria in the large intestine began to work, Li Dingsheng's blood oxygen saturation concentration reached 95%.
It fluctuated back and forth around 95% and never dropped again.
Because Li Dingsheng's lungs are still working, the saturation concentration can still reach 100% in many cases.
This data shows that Chen Xiao’s surgical plan is completely feasible!
Now everyone is excited!
Wu Yong, who was already sweating profusely, glanced at Chen Xiao excitedly and said excitedly: "Professor Chen! This kind of treatment can definitely apply for the Nobel Prize!"
Wu Yong has never been so excited.
The last time I felt like this was when I got the postgraduate admission notice from the School of Medicine of the Chinese Academy of Sciences.
But the operation has not been completed yet, so everyone can only hide this excitement in their hearts.
What remains is a difficult operation - complete lung removal.
The operation had been going on for eight hours at this time.
Li Fengmei outside the operating room felt that every second was torture.
She cried all her tears, but there was nothing she could do except wait.
drop!
The lights in the operating room went out.
The Li family members quickly gathered at the door of the operating room.
Wu Jun and others walked out extremely exhausted.
Li Fengmei hurried over and asked, "Professor Wu, how is the situation?"
