Chapter 279 Surgery
For the next period of time, Zhang Qingfeng was working with a group of imperial doctors to compile textbooks.
Everyone has an opinion on how to teach students, and sometimes it's hard to agree on it.
However, after working with each other for a period of time, the textbook was finally compiled.
Then Zhang Qingfeng asked a printing workshop of the imperial court to print thousands of sets of textbooks.
Meanwhile, enrollment continues.
"Da Song Daily" and "Da Song Daily", as well as "Da Song Royal Daily" run by a Zhao family clan, these three newspapers have been publicizing the admission of students to the medical school for several days in a row.
The requirements for enrolling students in the medical school are very simple. They must be between the ages of 13 and 20, be able to read and write, and have no physical disabilities. There are no other requirements.
The medical school promises that if you have excellent academic performance, you will be accepted as a disciple by the imperial doctor, and you will also have the opportunity to become a court official.
After the news spread through the two newspapers, many scholars soon came to sign up.
On Zhang Qingfeng's side, the imperial court assigned a few subordinate officials to fill in the vacancies. With the help of these people, the registration work was carried out in an orderly manner.
In just a few days, the medical school screened and accepted thousands of students.
Even so, many people signed up later, but because the medical school couldn't accommodate it and the teaching staff was insufficient, the recruitment was stopped.
In the following time, the imperial doctors taught the students according to the teaching materials, while Zhang Qingfeng was busy making microscopes and purifying alcohol.
For the microscope, Zhang Qingfeng handed over the work of polishing the lens to the mirror polishers in the palace.
These craftsmen have been grinding the copper surface into a flat and smooth mirror surface for many years, and they have a unique advantage in polishing the lens.
As for purifying alcohol, this was relatively simple. He asked some craftsmen in the Ordnance Supervision to build a set of distillation equipment according to his requirements.
The alcohol concentration in ancient times was very low, and Zhang Qingfeng needed several operations to purify pure alcohol.
After the pure alcohol is purified, distilled water and pure alcohol without other impurities are finally used to blend, which is almost the ratio of 70.00% alcohol to 20.00% water.
As for why it is necessary to purify the pure alcohol before blending, the main reason is that the alcohol content is not known after one purification.
Too high and too low alcohol content is not good for killing bacteria.
High concentration of alcohol will form a protective film on the surface of the bacteria, preventing it from entering the body of the bacteria, making it difficult to completely kill the bacteria.
Only alcohol with a temperature of about 75 degrees is the most suitable, which can coagulate the protein components of bacteria and prevent bacteria from forming a self-protecting film, so that alcohol can continue to penetrate into the inside of bacteria to completely eliminate and sterilize them.
The method of purifying alcohol is also very simple. The boiling point of alcohol is only [-] or [-] degrees, and the boiling point of water is [-] degrees. As long as the temperature of the wine is heated to about [-] degrees, the alcohol can be turned into a gas, and then the gas can be cooled. Can be reduced to high concentration alcohol again.
In fact, in the Southern Song Dynasty, distilled liquor was sold among the people. This was a distillation technology brought by nomads.
The distillation equipment made by Zhang Qingfeng is more reasonable than the folk distillation equipment, and the alcohol content that can be purified is also the highest.
half a month later.
Dasong Daily published an article on it, saying that Dasong Medical College has invented a new drug that can treat trauma with a high probability. If someone has a wound that festers and cannot be cured in a pharmacy, they can go to Dasong Medical College for treatment.
After the news was released, several patients came to the medical school that day.
In a classroom of the medical school, countless medical students sat down. On the podium, an operating table was placed on it. On the operating table, a patient was tied up.
The patient had no clothes on, and someone cut him on the waist. Everyone could see that the wound on the man's waist had festered, and it was a purulent infection of the wound.
This person was carried over by a group of family members at noon, and it is said that he was slashed half a month ago in a fight with someone.
I have seen many doctors and used many medicines, but the wound has not healed, but it is getting worse every day.
Such an injury is basically hopeless in this era. It depends on whether the individual's physique is good. If the physique is good, it can last longer. If the physique is not good, it may die in a few days.
This patient is also the most serious wounded person received by the medical school today.
When a group of imperial doctors saw the patient's injury, they just shook their heads and concluded that it was impossible to save him.
However, Zhang Qingfeng kept the patient. He planned to perform an operation to save the patient and use this patient to teach the students and teachers of the medical school.
Zhang Qingfeng only hoped that this patient has not allowed the infection to spread to the blood, causing the toxin to spread throughout the body and form a toxemia.
Zhang Qingfeng also signed a contract with the patient and his family members when he promised to treat the patient. No matter whether he can save his life or not, the patient's family members will not trouble him.
"Students, our hypothetical theory is that wound ulceration is caused by many tiny insects that are invisible to the naked eye."
"Next, what I have to do is to cut off the broken flesh of the patient with a knife, then sterilize it with alcohol, and then bandage it. If it is saved, it will prove that alcohol can kill these tiny bugs, or It can be disinfected." Zhang Qingfeng explained while operating.
He used a scalpel to cut open the broken part of the patient tied to the operating table, and then forcefully squeezed out the pus.
"what……"
"pain……"
"what……"
Immediately, the people on the operating table let out screams.
Fortunately, the patient's whole body was tied up, and there were two young and strong men holding him down. No matter how hard he struggled, it would not help.
Zhang Qingfeng didn't care about the patient's screams and struggles, the most painful time hadn't come yet, so what's the rush?
Under Zhang Qingfeng's squeeze, most of the pus was squeezed out soon.
"Give me alcohol." Zhang Qingfeng said to an imperial doctor who was helping him.
Hearing Zhang Qingfeng's words, the imperial doctor quickly handed Zhang Qingfeng a bottle of alcohol in a porcelain bottle.
Zhang Qingfeng opened the bottle cap and poured the alcohol directly onto the patient's wound.
"Ah~~"
Suddenly, there was a scream like killing a pig.
Zhang Qingfeng didn't care, and while washing the wound with alcohol, he used tools to clean up the pus.
This man's wound was about two fingers deep, and the festering had already formed a gap two fingers deep and one or two fingers wide.
With such a big wound, basically all the flesh inside was rotted away.
Zhang Qingfeng scraped the festering flesh with a scalpel until it bled.
He didn't dare to scrape hard, for fear of scratching blood vessels and arteries, which would cause bleeding.
The operation took about half an hour.
The main task was to clean up the suppuration and then disinfect it with alcohol. After treating the wound, Zhang Qingfeng sprinkled some of the best sore medicine in the palace on the wound and then wrapped it with a sterilized bandage.
When we got here, the operation was considered complete, and when we looked at the patient again, the pain was no longer there, and he was moaning and moaning all the time.
Fortunately, Zhang Qingfeng didn't cut flesh or anything, so the patient wouldn't go into shock.
"Okay, let's carry him to Ward No. [-]. As for whether it will be better or not, it depends on God's will." Zhang Qingfeng said to the two staff members.
In this era without antibiotics, Zhang Qingfeng cannot guarantee that this patient will be cured.
