Chapter 123 Preparation for Breast Cancer Surgery
She had to go back and figure out how to make ether; this was a project that could not be delayed any longer.
This long-acting anesthetic is required for breast cancer surgery.
Su Yuejian asked Su Quan to find an alchemist. She remembered that the alchemists of this era were quite amazing. Some chemical raw materials were first discovered by them.
According to the alchemist, Su Yuejian found the "method of refining stone gall to extract essence" in the book "Huangdi Jiuding Shendan Jingjue", which is the process of dry distilling gallbladder to obtain "green alum oil".
The "green vitriol oil" here refers to sulfuric acid.
"Use earth to build two square-headed furnaces, two feet apart, and fill each with fine mud inside and outside. Make a hole on the side, also fill it with mud inside and outside, so that the fine mud can be smoked and dried.
In one furnace, a copper plate is placed and allowed to settle, and then covered with mud; in another furnace, charcoal is burned to produce gallstones (gallstone vitriol), which are then fanned with an object, and the essence of the smoke enters the copper plate.
The fire in the furnace is turned off and waited for it to cool down before it is opened for use. This is the process of distilling gallstones and making sulfuric acid as recorded in ancient books.
This is not difficult. With crude sulfuric acid, it is not difficult for Su Yuejian to concentrate it into concentrated sulfuric acid. The only difference is that concentrated sulfuric acid is highly corrosive. Fortunately, she already has quartz glass beakers and utensils, otherwise she really doesn't know what other materials can be used to hold it.
The production of ether is simple. It is actually a clear liquid obtained by distilling a mixture of sulfuric acid and alcohol.
But it is complicated. First, she had to build a reaction device. When she first started making anesthetics, the conditions were not yet ripe.
Now we have quartz glass, which is resistant to acid corrosion and high temperature, making the experiment feasible.
Su Yuejian clamped beakers of various shapes with iron clamps, connected the curved tubes, straight condensers, connecting tubes, and conical flasks to their respective positions, and placed the ice water bath on the lifting rack.
Then add the reactants and heat to react.
After completion, the crude product is isolated, which requires the use of sodium hydroxide solution.
This was not difficult for her. She first found a natural alkali mine (containing sodium carbonate), dissolved and purified it, added clear lime water to react, filtered out the precipitated calcium carbonate, and the remaining solution was sodium hydroxide solution.
Pour an equal volume of 5% sodium hydroxide solution to the crude product into a conical flask, transfer it to a separatory funnel, wash the crude product, let it stand to separate the layers, discharge the lower aqueous solution, and then take 5 mL of saturated salt water/saturated calcium chloride solution to wash the solutions respectively.
Finally, transfer the ether in the separatory funnel to a dry conical flask, take a spoonful of calcium chloride with a medicine spoon, and distill it.
Finally, laboratory ether was obtained.
It’s the smell of the operating room in the previous life!
After obtaining ether, she conducted experiments on rabbits based on the previous anesthetic experiments, and the results were very good.
Now that she has the ability to heal herself and is not afraid of problems, she experiments on herself.
As a result, the injection anesthesia had an ideal depth and duration, and the dosage was the same as in the previous life.
At this point, 70% of the preparation for breast cancer surgery is complete.
Such a rough process sounds extremely troublesome. In fact, the experimental steps for all reactions combined involve at least a hundred steps, and the process is extremely dangerous.
After Su Yuejian has extracted a sufficient amount, she will pass the extraction technology to Shaoyao, and a written version of the production method will be kept for the Shen family.
When medical science develops to the right time in the future, I will consider restarting this project.
Su Yuejian decided not to promote it to the outside world for the time being. If she was not careful, the experimenters would get hurt first.
If the extract is impure, the patient may have an accident.
This is a dangerous chemical and a controlled substance, so it cannot be abused and promoted on a large scale, otherwise it will result in more people being saved than harmed.
After the operation, Su Yuejian will seal up the remaining ones.
After half a year of study, Wang Wenjun is now able to master some nursing-related skills.
Even debridement and suture can be performed.
However, due to late entry, many basic medical knowledge systems have not yet been established.
If she joins the surgical team, she can barely be an operating room nurse when there is a shortage of manpower.
When she first said she wanted to learn medicine to save Su Yuejian, Su Yuejian actually wanted her to have a practical skill. It was hard to say whether she could meet a good man in this era after the operation.
However, by studying medicine and seeing through the normal life of birth, aging, sickness and death, you will not fall into the dead end of “why me?”
Treating others’ illnesses is not only about saving people, it’s also about healing yourself.
Su Yuejian hopes that she can use her own hands to help others, realize her own value, and not continue to fall into negative emotions.
As for Su Yuejian's mastectomy surgery, she had actually planned to train Shaoyao to be her surgeon five years ago, so she spent the most time on it over the years.
It is true that the Wang family has a clear family genetic tendency, and Wang Wenjun already has a small lump in her breast.
For half a year, Su Yuejian used microvision to observe every month and found that the small lump had grown a little bit, so Su Yuejian had to speed up the process.
At present, Wang Wenjun needs to undergo a mastectomy and immediate breast reconstruction. She is also waiting for a female corpse and wants to perform the entire operation again with her team as a rehearsal.
In the past, they had undergone mastectomy at the Yizhuang in the capital, but immediate breast reconstruction was not performed at that time.
The experiment took the longest time, and they also dissected a male during this period. There were more male death row prisoners in this era.
The surgical nurse and Wang Wenjun have already survived the period of physical discomfort.
Another good news is that the medical technicians who came back for further studies this time include Shen Nanxing and two other medical technicians.
Shen Nanxing hadn't seen Su Yuejian for a long, long time. Ever since that conversation, he decided to let it go.
Hearing that she was planning to perform a difficult operation, he decided to study with this group of trainees.
He also wanted to try to see her again and see if he would have any more thoughts.
Renxintang now has so many medical professionals that they can still cope with the situation even if he is missing for a few months.
When they met again, Su Yuejian was not embarrassed. They had worked together for so many years, and even if there was no love, they still had a deep revolutionary friendship.
Shen Nanxing acted very frankly, so Su Yuejian naturally felt relieved.
Yuejiantang is bright and beautiful because of Shen Nanxing's arrival.
He is the owner of Renxin Hall, young, handsome and elegant. Su Yue sees many girls coming in and out here. When they suddenly see such a dazzling man, they will blush and talk about whether he has an engagement behind his back.
It was also the first time that Wang Wenjun met Shen Nanxing, such a graceful and elegant lady!
Wang Wenjun, who has always been simple and open-minded, blushed for the first time.
She also understood that her love life was bound to be bumpy, but since God had allowed her to meet the person who made her heart beat at first sight, she didn't want to escape.
That day, Gu Bingxiu sent someone to inform that they could go to the charity cemetery, as there was a female death row prisoner who met the requirements. Su Yuejian was very happy, as she had finally waited for the cadaver teacher!
Take everyone straight to the charity cemetery.
There were guards guarding the outside, and Wei Yuzhu followed closely inside.
Firstly, it must be kept strictly confidential and no one else can be allowed in. Secondly, having these people guarding can also give courage to others.
Everyone put on masks and took their tools and started according to their usual dissection process.
Wang Wenjun learned the most carefully because this exercise or rehearsal was tailor-made for her.
