This time, it wasn't an X-ray film, but a B-ultrasound.
From the looks of it, it seems to be the knee.
Viewing the B-ultrasound image, Zhou Can had been greatly exercised in the Emergency Department. His tutor was a master like Dr. Xu.
The skills of his direct disciple were naturally not lacking.
He spotted the problem at a glance.
"The patient appears to have right knee joint effusion, and it's quite severe. It is recommended to aspirate the effusion first, then inject medication for treatment. The preferred medication is hyaluronic acid, such as sodium hyaluronate."
At this moment, Zhou Can finally understood the meaning of accumulating knowledge over time.
The practical experience in the Emergency Department, coupled with the medical knowledge he learned from studying medical books, became the weight that put him ahead of other trainees.
The other four trainees looked at him, all dumbfounded.
Damn! Is this really just a trainee?
Why does it feel like his ability to read films is even stronger than that of an attending physician?
In this group, encountering such a 'monster' really is bad luck.
In today's OR competition, they are most likely to be outperformed by Zhou Can.
Doctor Shan's eyes showed surprise when she looked at Zhou Can, a surprise not even her black-rimmed glasses could hide.
This trainee from the Emergency Department truly lived up to his reputation.
She now seemed to understand why Director Shen had that expression when he heard Zhou Can's name.
Director Shen must have known about Zhou Can's abilities.
"This patient's treatment is a bit special; a bone cavity puncture is required, and the operation is extremely difficult. Not to mention you guys, even I need to be very careful to achieve a successful puncture. You all just watch and learn the steps carefully."
The patient was quickly brought in.
It was an elderly lady with white hair, her left knee swollen as thick as her thigh.
It looked rather scary.
When she was wheeled in, she kept moaning in pain.
Such joint pain is very torturous.
It's not the kind that can kill a person with immediate pain. Instead, it's like a dull knife cutting the flesh, slowly tormenting a person until their will collapses.
"Grandma, we will start treating you right away, please sit properly and keep still in this position."
For knee joint cavity puncture, it's best for patients to be seated during treatment.
This makes it easier to choose the puncture point.
"Alright, you all come over here and take a look. The puncture point is chosen at this spot."
Doctor Shan marked the puncture point with a pen.
"This puncture point is not the only one. Based on the patient's actual condition, you can choose to puncture from the inside or outside just below the patella. If puncturing from the outside, it should be at this position."
She taught very meticulously.
The first assistant, who looked to be in his late twenties, must be a Resident Doctor. He seemed to have mastered the task of puncturing the knee joint cavity and was just watching from a distance.
He didn't come closer.
"After finding the puncture point, first use a 5mL syringe to pierce into the joint cavity from this part. When you feel a breakthrough, it means... uh, you have to feel the breakthrough to indicate that it has been successfully inserted."
Her expression froze for a moment, as the syringe puncture seemed to encounter resistance.
"Ow... young lady, be gentle, be gentle..."
The patient cried out in pain.
Doctor Shan couldn't help but blush.
When did it go wrong? It had to be during her teaching moment with the trainees.
Isn't this just making her lose face on purpose?
The Resident Doctor seemed to notice Doctor Shan's predicament and quickly came forward to help.
"Doctor Shan, we men have a bit more strength, let me give it a try!"
He said this, obviously taking care of Doctor Shan's face.
Helping her out of the awkward situation.
"Puncturing the knee joint cavity is not easy to succeed, it's a Level 2 operation. Be careful and do not use brute force."
She appreciated the male doctor's help and took the opportunity to step aside.
The male doctor took the syringe, changed the needle, and tried to puncture again.
The veins on the male doctor's hand were showing, he definitely had quite a bit of strength. The old lady screamed in pain, even her voice changing.
She kept slapping the armrest of the wheelchair.
It might have really pierced her painfully.
If it didn't hit the mark, and hit the bone membrane instead, that kind of pain is undoubtedly deep in the bones. No one could stand it.
"Doctor Tang, take a break, let me do it!"
Doctor Shan didn't dare to let the Resident Doctor continue.
She looked at the patient's films again, saying with some embarrassment, "It's possible that the patient's joint degeneration is quite severe, and the difficulty of puncture has increased exponentially. But that's okay, we can also try puncturing from the outside just below the patella."
She switched to a new needle, while pacifying the patient, she located the puncture point on the outside and then carried out the puncture.
From her expression, she was definitely cursing the situation; what the hell, it's stuck again.
Zhou Can had been watching from the side the whole time.
He had also seen the patient's films.
Just as Doctor Shan mentioned, only B-ultrasound was performed which cannot clearly show the bones of the knee.
Possibly due to severe joint degeneration, the normal puncture points became ineffective for the puncture.
After Doctor Shan attempted two more times, her face turned red, and sweat started to appear.
During teaching, one mistake was embarrassing enough.
Who would have thought, after switching to the outside for puncture, it still wasn't successful.
And this was only the initial puncture.
It was truly embarrassing.
"Doctor Shan, as it happens, I've also practiced puncture, let me try!"
Zhou Can's Injection Skill level was as high as Level 4, the medium level for an attending physician.
Previously when he obtained his Injection Skill, he felt that this medical skill might not be of much use.
Its use, apart from giving injections, could also be applied to punctures.
