The main purpose of mixing a small amount of adrenaline into the local anesthetic is to reduce bleeding in the surgical field, making the surgical view clear.
It also can reduce the absorption of local anesthetics and decrease their toxic side effects.
There are quite a few benefits.
He didn’t dare to play like this before.
He used to be extrely careful and cautious when administering dication to patients.
Now it seems casual, but it’s because he has a sufficiently high level of skill, so he can handle heavy tasks with ease.
"I heard that your dical skills here are very high, that’s why I specially ca here for treatnt. You must do the surgery well for !"
The patient interrupted upon hearing their conversation.
"We will definitely do our best to perform the surgery the best we can for you. We are about to administer the anesthesia, please try not to speak."
Li Jingsheng said to her.
"Sister Tang, please push the suction machine over here. We will definitely need to suction sputum, pus, and blood later."
This suction machine was bought by Li Jingsheng clenching his molars back then.
It has been sitting in the treatnt room collecting dust.
The number of tis it’s been used is no more than three.
If the surgical business develops in the future, it will find its place.
Before administering the local anesthetic, Li Jingsheng still maintained a cautious deanor.
He did a skin test first.
Only after confirming that there was no problem did he proceed with intraoral injection.
"Sister Tang, with patients who have internal abscesses, it’s best to avoid injecting near the abscess area."
"I know! Our director specifically taught before. Actually, if conditions permit, superficial injection or injection from the outside can be done."
Tang Ping raised her beautiful willow-leaf eyebrows.
The expression on her face was unclear because she was wearing a mask.
But her pride could be seen in her eyes.
Her level is quite high, and she can even teach Li Jingsheng about nursing knowledge.
"Ha, I almost forgot you used to be an excellent nurse from the hospital."
Li Jingsheng chuckled twice.
Once the local anesthetic took effect, he took a retractor, and together with Tang Ping, they pulled open the patient’s mouth.
If there were enough staff, a dedicated dical assistant would be needed to handle the retractor.
Now this task can only be done by Tang Ping, the delicate female nurse.
Handling the retractor is actually a physical job, usually assigned to young male interns or resident physicians.
If there are no such beginners, it’s passed up to the attending physicians.
Newcors to the operating room get the chance to handle the retractor once, and they feel quite happy.
After staying longer, they realize it’s purely a laborious job without much technical content.
The only benefit is the chance to step onto the stage and watch the lead surgeon perform the procedure up close.
Li Jingsheng opted to start the incision from the lowest point of the swollen area for drainage.
This is a common mistake made by many beginners.
The textbook ntions making the incision at the highest point of the swollen area for drainage.
That refers to making incisions from outside the oral cavity, thus choosing the highest point of the abscess.
If the incision is made intraoral, then it should start from the lowest point.
Currently, Li Jingsheng only has one incision technique above Entry Level, which is the skin incision thod.
Right now it is at Skilled Level 18/100.
It has not yet reached Master Level.
He hesitates a bit during the incision.
The nerves and blood vessels at the lower jaw are quite dense. If the force during the incision is not controlled properly and damages the nerves and blood vessels, it can harm the patient’s oral function, even leading to so facial function loss.
For example, so won like costic surgery and end up with a zombie face, unable to smile anymore.
If he slips during the incision, it can also lead to such consequences.
After considering for a mont, he decides to upgrade the skin incision thod by at least one level.
He needs to increase its proficiency to Master Level to ensure safety.
The current life value balance is 127.
He decisively spends 82 life value points to temporarily upgrade the skin incision thod to Master Level.
Now it’s solidly at a low-grade Attending Level.
Capable of handling intestinal incisions, naturally a superficial oral cavity abscess incision is no problem.
With this upgrade in incision technique, Li Jingsheng’s application of this thod improves drastically.
Focusing, carefully cutting open the lower area of the abscess.
A slit appears instantly.
He is pleasantly surprised to find the feedback from the tip of the knife is remarkably clear. This is a feeling he has never experienced before.
"Could this be the knife feel?"
He always thought the knife feel could only be achieved at deputy director level.
Unexpectedly, reaching Attending Level already allows a preliminary knife feel.
With one cut, he can clearly feel the depth of the incision.
At Skilled Level, the skin incision thod allows more precise control over the angle of the cut, resulting in a straight line.
Rather than a jagged wound.
Novice doctors at lower incision skill levels produce uneven wounds.
The better ones might result in wave-shaped wounds.
These all indicate low proficiency with incision techniques.
Surgical skills heavily rely on experience. The older the doctor, the more favored they are.
Because so doctors, working until over 70, complete five to six thousand surgeries; their experience is unfathomably rich.
With a tumor, just feeling through the skin can reveal its nature.
The incision technique is one of the most crucial surgical skills and the foundation of all anatomical procedures.
Including the separation technique developed from the incision technique, which is also based on it.
Li Jingsheng finds that after upgrading the skin incision thod to Master Level, the precision in controlling the depth of the incision improves, and the cut line is straighter.
Nearly like drawing a line with a ruler.
Additionally, the feedback from the knife feel excites him greatly.
He doesn’t make a single cut through the abscess directly.
For an abscess incision drainage surgery, you must never cut through entirely in one cut. Even chief physicians dare not be too aggressive.
They all cut layer by layer.
Maximally avoiding surgical accidents.
"The touch, the knife feel is so silky smooth!"
He feels like peeling clothes.
At this point, yellow pus is already visible just beneath the tissue layer.
Don’t know if it’s due to his improved dication skills, mixing adrenaline with local anesthetic, or because the skin incision thod was upgraded to Master Level, but the amount of bleeding during the surgery is very minimal.
So little that he can’t believe he’s this good.
He heard that the top surgeons can complete major surgeries with total blood loss under 50ml.
Sothing he never dared to imagine.
But now, Li Jingsheng dares to consider it and believes this legend is true.
Maybe one day he can also reach this supre realm.
"Sister Tang, are you okay with the retractor?"
"I’m fine, I can hold on."
After all, she is a woman, not as strong and enduring as n.
Now it’s visible she’s gritting her teeth to persist.
Li Jingsheng picks up the suction gun with one hand, cuts open the final tissue layer of the abscess, and a large amount of pus gushes out instantly.
However, it is quickly suctioned away.
The whole operation coordination is seamless.
This feeling is akin to learning Zhou Botong’s ambidextrous technique.
