I make a popular science video and all the emperors learn from it!

【Collection of short videos on popular science and modern medicine】

【Eight: Surgery】

【Surgery, commonly known as surgery, refers to the treatment that doctors use medical instruments to perform excision, suturing, etc. on the patient's body.】

【Use knives, scissors, needles and other instruments to operate on parts of the human body to maintain the patient's health】

【It is the main treatment method of surgery, with the purpose of treating or diagnosing diseases, such as removing diseased tissue, repairing damage, transplanting organs, improving the function and shape of the body, etc.】

【Early surgeries were limited to simple manual methods of incision, cutting and suturing on the body surface, such as abscess drainage, tumor resection, trauma suturing, etc.】

【Therefore, surgery is an operation that destroys the integrity of the tissue (incision), or restores the integrity of the tissue (suture)】

【With the development of surgery, the field of surgery continues to expand and can be performed on any part of the human body.】

【The instruments used are also constantly updated. For example, scalpels include electric scalpels, microwave scalpels,"917" ultrasonic scalpels, laser scalpels, etc.】

【Therefore surgery also has a broader meaning】

【Surgical methods:】

【1. Indications for surgery】

【Indications for surgery, also known as surgical indications, refer to illnesses that are suitable for a certain type of surgery. For example, subtotal gastrectomy is suitable for the treatment of gastroduodenal ulcer and gastric cancer. Surgical contraindications refer to situations where a certain type of surgery is not suitable】

【2. Surgical position】

【The patient's position during surgery should be easy to operate and the patient can tolerate it.】

【Most surgeries are performed in the supine position】

【Others include prone position, lateral position (such as some thoracotomy surgeries), sitting position, etc.】

【...】

【3. Asepsis】

【Most sterile surgical incisions heal well】

【However, bacteria are commonly found in the human body and the surrounding environment, so measures must be taken to prevent bacteria from entering wounds】

【Asepsis is this kind of preventive measure, including sterilization, antibacterial and related rules and regulations, which is usually called disinfection and sterilization.】

【4. Sterilization method】

【Use physical methods to completely eliminate bacteria on surgical instruments and dressings. Commonly used methods include: high-pressure steam sterilization, boiling sterilization, and fire.】

【5. Antibacterial method】

【Antibacterial methods refer to the application of chemical methods to eliminate bacteria】

【For example: alcohol, potassium permanganate, etc.】

【Preparation for surgery:】

【Surgical preparation is a chemical disinfection process to prevent bacterial infection of the surgical incision.】

【......】

【Operating room requirements:】

【The main places for surgical operations have different equipment conditions, but the basic requirements are similar, that is, the location is moderate in size, has good lighting and ventilation, and is easy to clean and disinfect.】

【It is best to build the operating room at one end close to the surgical ward or on the upper floor of the building to facilitate patient transportation and management; try to arrange it on the north-facing side to maintain constant, soft light; the area varies depending on the purpose of use, generally 30 left and right; equipped with tile walls and terrazzo floors】

【If you use paint, it should be light blue or light green, and there should be a screen】

【Advanced operating rooms have adopted ultrafiltration laminar flow devices. It is best to have a resuscitation or postoperative recovery room near the entrance. In grassroots or field hospitals, the requirements cannot be too high, just clean and bright.】

【The operating room should have strict rules and regulations, and should be cleaned, ventilated, and disinfected regularly】

【something else:】

【......】

"Madam, please call our son to study! If you learn this, you will never have to worry about food and drink for the rest of your life."

"Oops, this seems to be the Western medicine that Guangmu mentioned. At first glance, it looks really different from our medical skills."

"I am a butcher, and I have good knife skills. I have decided that I will change my career to learn this, and become a doctor to save lives and heal the wounded!"

"......"

In ancient times, people were very enthusiastic.

Medical technology they had never seen before excited them.

Anyone with a discerning eye can see that anyone who can learn to operate, even if he just stitches up people's wounds, can still support himself.

It’s much better than being a farmer farming.

It’s decent and has a way of making money!

What is even happier is the group of people who are originally doctors.

The eighty-year-old traditional Chinese medicine doctor went out on crutches. After seeing it, he was so excited that he was shaking all over.

Then he shed two lines of tears of regret.

I can't help it, my hands are shaking as I get older.

Even now that I have learned how to operate, I still dare not perform it on others.

I regret not seeing it decades earlier!

Otherwise, how many people could have been saved?...

Qin Dynasty.

The whole world celebrates the medical people.

Western medicine, which I have been waiting for for a long time, finally appears....

"Knives, scissors, needles, we all have these tools"

"disinfect?" (To read exciting novels, go to Feilu Novel Network!)

"Is the air toxic? ?"

"Sterilize by burning or boiling water..."

Everyone was lost in thought.

They didn't understand the principle, and when they found that they couldn't figure it out, they simply stopped thinking about it.

The most important thing is to be able to save talents. As for why we do this, we will study it later.

"alcohol disinfection"

"This is easy to solve. You can also use other alcohol to distill high-strength alcohol."

"The operating room also needs to be disinfected..."

"Surgery is a waste of time."

The doctors were silent.

Unexpectedly, the biggest problem in performing surgery was whether there was enough high-alcohol alcohol. Zhang Zhongjing, a medical sage in the Han Dynasty

, meditated while recording.

The knowledge of light curtain science greatly enriched his medical theory[]

This includes viruses in the air.

He never understood why he had to put tools on the fire when cutting or suturing wounds.

Now he knew why.

Zhang Zhongjing nodded happily,"In the future, I can safely operate on patients. I also need to prepare some alcohol."

5.8 The Three Kingdoms Period.

Hua Tuo was going crazy with joy

"Operation!"

"It's surgery"

"My craniotomy must also be an operation"

"It seems that the preparations were still insufficient. There was no operating room, disinfection was not in place, and even the tools were not well prepared."

"Prime Minister! Prime Minister, you are saved! Hua

Tuo shouted.

This immediately aroused the dissatisfaction of the soldier leading the way. He pushed him and shouted:"Why are you shouting!" The Prime Minister's illness has been cured. How dare you curse the Prime Minister!"

"Come in quickly, the Prime Minister is waiting for you"
