Lin Ran has been a little busy recently.

As the backbone of the Medical College of Guanshishan Academy, Lin Ran has recently been invited by the Military Medical Department of the Royal Military Academy of the Tang Dynasty to give lectures.

The military medical department faces the most various types of trauma, and this is Lin Ran's area of ​​expertise.

"tweezers!"

"Scissors!"

"Hemostats!"

"gauze!"

In the Jamroom of the Military Medical Department, Lin Ran was demonstrating wound suturing to the trainees of the Military Medical Department.

"Lin Jiaoyu, wouldn't it increase the risk of infection if the gauze is wrapped around the wound?"

Lin Ran's surgery can be regarded as a teaching demonstration surgery.

Inside the jam room, dozens of students from the military medical department stood densely packed.

"Chaoyue said, if we use ordinary cloth to help the wound, it will indeed increase the risk of wound infection. I believe you all know that the microorganisms on these cloths will make the wound more susceptible to inflammation. But our gauze is different.

This is the medical gauze launched after the latest improvements from Guanshishan Academy's Gewu Academy. It is not only breathable but also sterilized.

Using these gauze to help wounds will not only not increase the risk of infection, but will actually reduce it. Moreover, for deep and wide wounds, the wound healing speed will be much faster after using gauze."

For example, with the minor surgery in front of him, Lin Ran was able to do both surgery and teaching at the same time.

The student who was asking the question now was the most talented in the Military Medical Department of the Royal Military Academy of the Tang Dynasty, and Lin Ran was even more willing to answer his questions seriously.

Speaking of which, as a medical family, the Chao family has not only occupied a long-term position in Taiyuan Hospital, but Renxintang is also famous in Chang'an City.

Now that the Military Academy has a military doctor, the Chao family naturally has children joining the academy.

Although Chao Yuedao is not a direct descendant of the Chao family, he still has the surname Chao.

"Is this why our military medical department lists gauze as a necessary item in the medical kit?"

The medical kit is the most common thing around every student of the Military Medical Department of the Royal Military Academy of Datang.

According to the regulations of the Military Medical Department, every trainee needs to carry a medical kit at all times unless there are special circumstances.

In addition to commonly used surgical instruments, disinfectant alcohol, health pills and other items, it also recently added gauze.

Although the weight of gauze is very light, everyone is still more concerned about the addition of things to the medical kit.

"That's right. If this gauze is on the battlefield, it will be one of the most important items for soldiers to save their lives. Especially when there are a large number of wounded, the doctors in the army will definitely not have time to deal with the wounded one by one. At this time,

It is of great significance to use gauze to tie the wound urgently to avoid massive blood loss and missed treatment opportunities.”

Although Li Kuan only briefly mentioned this theory to Sun Simiao and Lin Ran, after several tests, Lin Ran completely believed in Li Kuan's theory.

Moreover, under his suggestion, gauze became the most common medical material in the Military Medical Department of the Royal Military Academy of the Tang Dynasty, and it also began to be widely used in the Affiliated Hospital of Guanshishan Academy Medical College.

In a sense, the emergence of gauze has played a huge role in the development of surgery.

Although it is not as significant as disinfectant alcohol, its auxiliary role in wound healing is not small at all.

…

"Your Majesty, why did you ask people to change all the mosquito nets?"

In the palace of Prince Chu, Cheng Jingwen asked Li Kuan a little doubtfully.

In the past, Li Kuan would definitely not care about trivial matters like changing mosquito nets, let alone arrange for people to do it himself.

Otherwise Cheng Jingwen wouldn't find it strange.

"Jingwen, have you noticed that this mosquito net is different from the previous one?"

Li Kuan looked at the very ordinary mosquito net in front of him and said with a smile.

As the palace of the Prince of Chu, a wealthy country, the mosquito nets in the past were basically made of silk.

Mosquito nets made of silk are high-end, but after being cleaned several times, problems of one kind or another may easily occur.

Moreover, this silk mosquito net is easy to deteriorate.

Although the Chu Palace was not short of money, Li Kuan spent a lot of effort to find more applications for cotton.

Needless to say, the cotton cloth, the gauze cloth is also outstanding for Li Kuan.

Today's mosquito nets are no exception.

Although this mosquito net may seem inconspicuous, it can be regarded as a product with a long history.

Basically, it is a necessary material for every household.

The idea is that the sanitary conditions are not as good as those in later generations, but the greening is much better than in later generations, so naturally there will be no shortage of mosquitoes.

Although there is no dengue fever, there are so many mosquitoes that no one can stand it.

"Is there any difference? They seem to be the same."

Cheng Jingwen usually pays very little attention to mosquito nets, and she really doesn't see any difference between the mosquito nets in front of her.

Of course, it used to be dyed, but now it's white.

However, she believed that Li Kuan definitely did not mean this difference.

"The raw material of this mosquito net is cotton. Compared with silk mosquito nets, its price is much lower; and compared with mosquito nets made of linen, its quality is much better. It can be said to be the best item for making mosquito nets."

Even in later generations, mosquito nets were generally made of cotton as the original material.

This can be regarded as side proof that cotton is the best partner for mosquito nets.

"Cotton? If every mosquito net in every household is made of cotton yarn processed from cotton, then the demand for cotton will definitely rise to a higher level. Cotton cultivation in Hedong Road will be even more significant."

Cheng Jingwen's brain was not bad, and she quickly thought of the meaning behind this matter.

"Cotton has many functions. In addition to cotton cloth, gauze and mosquito nets, cotton-padded clothes and quilts will also be the most important uses. You can't know how well the cotton you wore before has a thermal insulation effect. Once cotton

If the output continues to increase, the price of cotton will inevitably continue to fall. By then, the people will have the opportunity to afford cotton-padded clothes and quilts. This can be regarded as a scene of the prosperous Zhenguan era."

"So, the cotton planting area in Hedong Road must continue to expand?"

"That's right, not only Hedong Road, but also after the army takes over the Western Regions, I am going to propose to the court to promote the cultivation of cotton in the Western Regions, so that the Western Regions will no longer be dispensable, tasteless to eat, and a pity to abandon."

In Li Kuan's mind, the wider the territory of the Tang Dynasty, the better.

Even if it is not used now, it can be left to future generations.

In the past, the reason why the Central Plains dynasty did not have much desire to occupy places like the Western Regions was ultimately because the input-output ratio was too low.

Fighting a war is a waste of money and people, but nothing is gained in the end.
