She smiled and nodded, not saying another word.
But in her heart, she thought to herself, this isn't just a little progress. The boss's square knotting skill is no worse than that of an attending physician in a major hospital's operating room.
Usually, I haven't seen the boss practicing much!
"Scissors!"
Li Jingsheng spoke up to remind her.
After tying off the blood vessel, the suture must be cut. Cutting the suture seems simple but it actually requires skill.
The angle and position must be handled well, otherwise, it can easily damage the surrounding tissue.
The length of the thread left should not be too long or too short. Too long can irritate the surrounding tissue, causing foreign body symptoms. Too short can lead to the knot coming loose.
Li Jingsheng had put in a lot of effort practicing cutting sutures back in the day.
Because once an attending doctor asked him to cut sutures, and he ended up cutting them too short. The attending doctor didn't say much, just told him to leave the thread longer next time.
The head nurse scolded him harshly in front of other doctors and nurses, as well as the patients.
At that time, Li Jingsheng even wanted to strangle the head nurse.
He was so ashamed he wished he could crawl into a hole.
That experience was what made him decide to rigorously practice his suturing skills. He humbly sought advice from other doctors.
In hindsight, he still needs to thank that head nurse.
Her strictness ensured that Li Jingsheng wouldn't fail at even the simple task of cutting sutures.
Moreover, wearing sterile isolation gowns to enter the operating room seems simple but actually has very high sterile procedure requirements. Even a small oversight when tying the gown can render it unusable, necessitating a change.
When such matters occurred, Li Jingsheng naturally got scolded fiercely by the circulating nurse.
He used to think those nurses were too fierce.
Only after running his clinic for over nine months did he realize how endearing they were. They helped him change many bad habits, benefiting him for life.
Now, in terms of sterile procedures, he is clearly more standard than doctors at other clinics.
These benefits all came from being scolded by those fierce nurses.
After cutting the sutures, he checked the blood vessel's ligation status.
It was quite good; the ligation was secure, and the bleeding had stopped.
If it were before, he would have tied twice to ensure safety.
The core technique of ligation is knot-tying.
Proficiency in square knots not only greatly increased his knot-tying speed but also eliminated the need for a second ligation to ensure the vessel stops bleeding safely.
This also greatly improved his surgical efficiency.
After successfully stopping the largest bleeding source, the next step was debridement.
To be honest, his debridement skills were poor.
He hadn't even reached entry level.
At the moment, in order to earn money from this major job, he had no choice but to push himself.
First, he cleaned the inside of the wound with saline, then carefully observed the wound's condition, before finally trimming the wound with sterilized scissors.
He needed to handle the granulation and irregular skin edges.
Strictly speaking, this was his first time performing meticulous debridement on a patient's wound.
Previously, he would at most wash with saline or hydrogen peroxide and cut away severely damaged or heavily polluted skin layers and granulation.
At the moment, because the wound was long, the skin edges were not neat.
Some areas were uneven and jagged.
If this wound wasn't trimmed, it couldn't be stitched. Even if stitched, the wound would be extremely difficult to heal.
Debridement and suturing are known as the two essential skills for wound repair.
When combined, they form an unbeatable duo.
No matter how skilled the suturing is, a wound won't heal well if the debridement isn't properly done.
Experienced surgeons liken debridement and suturing to a pair of chopsticks.
Only together can you pick up food.
Neither chopstick can pick up food alone.
Li Jingsheng's forehead sweats finely.
Debridement is detailed work, with the patient and coworkers watching him operate, so he must avoid major mistakes.
He carefully trimmed the skin edges to make them align during sutures.
After nearly twenty minutes, the wound finally met satisfactory results after his debridement. Any further delays might test the patient's patience.
This debridement focused on the subcutaneous tissue layer, muscle layer, dermal layer, and epidermal layer.
He had to carefully look for any glass shards or debris left in the patient's wound, and during the granulation repair and skin edge trimming, he had to avoid injuring nerves, tendons, ligaments, and major blood vessels.
As for capillaries, one couldn't avoid them even if one wanted to.
The body is full of large and small blood vessels, like densely packed roots, covering every corner of the body.
According to statistics, if all the blood vessels of an adult were connected, the total length would be about 96,000 kilometers. The circumference of the Earth is just approximately forty thousand kilometers, making the total length of the body's blood vessels about 2.5 times Earth's circumference.
The body has over a hundred billion blood vessels of various sizes, a staggering number.
In surgery, doctors can only avoid the major vessels and large vessels.
Li Jingsheng, after cleaning the wound, took a careful look and felt fairly satisfied.
Considering his limited debridement skills, achieving this effect was already quite good.
This debridement for the patient yielded substantial gains, although he hadn't had the chance to check the attribute panel. Yet, he felt that his debridement skills might have reached an entry-level.
During the debridement, he learned many techniques and combined theoretical knowledge from books with practice, leading to a qualitative improvement in his debridement skills.
The next step was the crucial task of wound suturing.
Such a deep wound certainly required the newly learned vertical mattress suturing. This suturing technique could reduce the tension of the wound's skin, while also aligning the deep tissue layer and the superficial skin edge layer.
Tang Bo looked at the boss with some concern.
In her memory, Li Jingsheng shouldn't be capable of handling such a deep wound.
She knew that the boss had even sold his beloved motorcycle, surely reaching a point of financial desperation.
Earning this money was very important.
Therefore, the boss was working so hard.
In the past, the boss would have already sent the patient away.
But she didn't know that Li Jingsheng took on this task not just for the urgent need to earn money and keep the clinic afloat, but also because Master Liu desperately wished to be treated at his clinic.
Because this could save a large sum in treatment costs.
Additionally, he had just accumulated 10 life points and recently mastered vertical mattress suturing, enough to upgrade this suturing skill to a proficient level.
Having the ability to handle this task naturally meant going all-out.
"Dr. Li, can we start the suturing now?" Master Shun couldn't help but urge, waiting impatiently.
He was eager for Li Jingsheng to quickly finish treating Master Liu's wound and send him home, so he could get back to work.
It was already half-past one in the afternoon.
"Don't rush! Our boss hasn't even had lunch, he certainly wants to finish suturing quickly too. But surgical suturing is detailed work, and focusing only on speed leads to sloppiness. If the wound takes long to heal, or even gets infected, that would be troublesome. Slow work yields fine results, so please have patience, you two." Tang Ping once again spoke on behalf of Li Jingsheng.
Having such a smart and capable nurse allowed Li Jingsheng to save a lot of effort.
"Master Shun, why don't you go find work first. I can take a motorcycle ride back later." Master Liu was sincere but not naive.
He naturally knew what his coworker was anxious about.
"No way, I can't let you go back on your own with such an injury!" Master Shun was torn between rushing to the construction site and worrying about his coworker.
People depend on each other.
This time it's Master Liu's accident. If he doesn't care for him, next time if something happens to him, Master Liu probably wouldn't care either.
Li Jingsheng quickly opened the attribute panel, his eyes scanning over the skill column.
Entry Level Surface Debridement 0.1/10.
Adding another surgical skill made Li Jingsheng feel delighted.
Life seems promising!
Within just one day, he had gained two new medical skills, while also elevating three skills from entry level to proficient level. It is estimated that the progress of today is equivalent to a year of hard study in a major hospital.
Of course, ordinary medical students don't even have the opportunity to work in major hospitals.
Debridement is extremely important in surgical operations, considered one of the four fundamental surgical skills.
If he could upgrade this skill to a proficient level now, he should be able to repair Master Liu's leg wound more neatly and accurately. The result would be better when suturing afterward.
Resisting the urge to upgrade Surface Debridement to a proficient level, he focused on vertical mattress suturing.
Priorities must be set, and vertical mattress suturing must be upgraded to proficient level first.
As for Surface Debridement, it would have to wait until enough life points are accumulated to upgrade.
