She nodded with a smile and said no more.
But he secretly thought, this is not a small improvement. The boss's ability to tie square knots is no worse than that of the average attending physician in the operating room of a large hospital.
I never see how my boss practices!
"Scissors!"
Li Jingsheng reminded her loudly.
After the blood vessels have been tied, the sutures need to be cut. Cutting threads may seem simple, but it’s also very sophisticated.
The angle and direction must be grasped well, otherwise the surrounding tissue may be easily injured.
The thread left cannot be too long or too short. If it is too long, it will irritate surrounding tissues and cause foreign body signs. If the thread is too short, it will easily cause the knot to come loose.
Li Jingsheng had to work hard to practice thread-cutting.
Because once the superior doctor asked him to cut the thread, but unexpectedly it was cut short. The superior doctor didn't say much, but just told him to keep the thread longer the next time he trimmed it.
The nurse in charge scolded him in front of other doctors, nurses, and patients.
At that time, Li Jingsheng even wanted to strangle the nurse in charge.
I was so embarrassed after being scolded that I wanted to crawl into the cracks in the ground.
It was that experience that made him determined to practice thread-cutting skills. Ask other doctors humbly for advice.
Looking back now, I still have to thank the nurse in charge.
It was precisely because of her sternness that Li Jingsheng was not unable to do something as simple as cutting the thread.
Wearing isolation gowns when entering the operating room may seem simple, but in fact it requires very high aseptic operation requirements. Even if you don't pay attention when tying it, the sterile isolation gown will no longer be usable and will need to be replaced.
When this happened, Li Jingsheng was naturally scolded by the circulating nurse again.
I used to think those nurse girls were too fierce.
It wasn't until he opened the clinic for more than nine months that he realized how lovely those nurses were. Shengsheng helped him get rid of many bad habits, which will benefit him throughout his life.
Nowadays, he is obviously more standardized than doctors in other clinics in terms of aseptic procedures.
This was all due to the scolding from those fierce nurses.
After cutting the sutures, he checked the ligation of the blood vessels.
Not bad, the ligation is secure and the bleeding has stopped.
In the past, he would have had to be sterilized twice just to be on the safe side.
The core technique of ligation is knotting.
The proficiency level of square knot not only greatly improved his knotting speed, but also did not require a second ligation to ensure the safety of blood vessel hemostasis.
This also greatly improved the efficiency of his surgery.
After successfully stopping the largest source of bleeding, the next step is debridement.
To be honest, his debridement was poor.
Not even entry level.
At this moment, in order to make money from this big business, he had to fight hard.
First, clean the inside of the wound with alcohol, then carefully observe the condition of the wound, and then use sterilized scissors to trim the wound.
Granulation and disordered skin edges all need to be dealt with.
Strictly speaking, this was the first time he had performed fine debridement on a patient's wound.
In the past, the most I could do was wash it with alcohol and cut off some seriously damaged or contaminated cortex and granulation.
At this moment, because the wound is very long, the skin edge layer is not neat.
The damage was uneven in places.
If this kind of wound is not trimmed, there is no way to sew it up. Even if it is sutured, the wound will be extremely difficult to heal.
Debridement and suturing are the two major skills for wound repair.
When they cooperate with each other, they can be invincible.
No matter how sophisticated the suturing technique is, if debridement fails, the wound will still be difficult to heal.
A senior surgeon compares debridement and suturing to two chopsticks.
Only when they are put together can you pick up the food.
None of the chopsticks can pick up food on its own.
Li Jingsheng's forehead was dripping with sweat.
Debridement is a delicate job, and patients and co-workers are watching his operation, so no major mistakes can be made.
He carefully trimmed the edges of the skin so that they would line up when suturing.
After nearly twenty minutes, he debrided the wound and finally achieved a satisfactory result. If this continues, the patient's patience will be exhausted.
This time the debridement mainly covers the subcutaneous tissue layer, muscle layer, dermis layer and epidermis layer.
Carefully look for glass fragments and debris left in the patient's wounds. Then, during the process of repairing the granulation and skin edge layers, it is necessary to avoid injury to nerves, tendons, ligaments, and important blood vessels.
As for capillaries, you can't avoid them even if you want to.
The human body is covered with large and small blood vessels, like dense tree roots, covering every corner of the human body.
According to statistics, if all the blood vessels of an adult were connected together, the total length would be approximately 96,000 kilometers. It only takes about 40,000 kilometers to circle the earth. The total length of blood vessels in the human body is equivalent to 2.5 times the circumference of the earth.
There are more than 100 billion blood vessels in the human body, large and small, which is a super scary number.
Doctors can only avoid important blood vessels and large blood vessels during surgery.
After Li Jingsheng cleaned the wound, he looked at it carefully and found that he was quite satisfied.
After all, his level of debridement is limited, so it is already very good to be able to achieve this effect.
He gained a lot from debriding the patient this time, even though he didn't have time to check the properties panel. But he had a feeling that debridement technology might have already started.
During debridement, he learned many techniques, and combined the theoretical knowledge learned in the book with practice, which allowed him to qualitatively improve his debridement technology.
The next most important step is to suture the wound.
Such a deep wound would definitely require the newly learned vertical mattress suture. This suturing technology can reduce the tension in the wound cortex and at the same time align the deep tissue layers and superficial skin edge layers.
Tang Bo slightly looked at his boss worriedly.
In her impression, Li Jingsheng should not be able to deal with such deep wounds.
She knew that the boss had even sold his beloved motorcycle and must be at the end of his rope.
Making that money is very important.
That's why the boss is so desperate.
In the past, the boss would have pushed the patient away.
She didn't know that when Li Jingsheng took over this business, he was not only eager to make money and keep the clinic alive, but also because Master Liu desperately wanted to be treated in his clinic.
Because this can save a lot of treatment costs.
In addition, he happened to have 10 health points saved, and he had learned vertical mattress suture not long ago, which was enough to upgrade this suture skill to the proficiency level.
If you have the ability to win this business, you will naturally have to fight hard.
"Doctor Li, can we sew now?" Master Shun was waiting very anxiously and couldn't help but urge.
He also thought that Li Jingsheng would quickly treat Master Liu's wounds and then send Master Liu home so that he could go to work.
The clock has pointed to half past one in the afternoon.
"Don't worry, our boss didn't even eat lunch. He definitely wants to sew the wound quickly. But surgical suturing is a delicate job. If you only want to do it quickly, you will be sloppy. By then, the wound will not heal for a long time and may even become infected. , that would be troublesome. Slow work will produce fine work, you two, please be patient and wait."
Tang Ping spoke for Li Jingsheng again.
Having such a smart and capable nurse would save Li Jingsheng a lot of effort.
"Master Shun, why don't you go find someone to work first. I'll just take a motorcycle back later." Master Liu is a simple and honest man, but he is not stupid.
Of course you know what the workers are anxious about?
"No, no, you're so injured, how can I let you go back alone?" Master Shun was anxious to go to the construction site to work, but at the same time he couldn't worry about his coworkers.
People are all for each other.
It was Master Liu who had the accident this time. If he didn't take care of it, it would be wrong. The next time something happens to him, I'm afraid Master Liu won't care about his life or death.
Li Jingsheng quickly opened the attribute panel and glanced at the skill bar.
Introduction to surface debridement 0.1/10.
Li Jingsheng was very happy to have another surgical skill.
There is hope for this little day!
In just one day, two new medical skills were added, and three medical skills were upgraded from entry level to proficient level. It is estimated that one day's progress today is equivalent to one year of hard study in a large hospital.
Of course, ordinary medical students who want to work in large hospitals have no chance.
Debridement is very important for surgery and is one of the four basic skills of surgery.
If he could improve this medical skill to a proficient level now, he should be able to repair Master Liu's leg wounds more neatly and in place. Then the sewing effect will be even better.
Resisting the urge to upgrade body surface debridement to a proficient level, he targeted vertical mattress suturing.
Things have to be prioritized, and the vertical mattress suture must be upgraded to a proficient level first.
As for the surface debridement technique, you can only upgrade it after you have accumulated enough 10 health points.
