Chapter 340 The Place Where Rong Shows Off His Skills (Please Subscribe)

If it weren't for a series of coincidences, Fang Ziye would never have had the opportunity to meet a big shot like Professor Liu Huanglong.

If Professor Liu Huanglong hadn't happened to want to use Fang Ziye to exploit others, Fang Ziye would never have had the chance to talk to Professor Liu Huanglong, let alone think about becoming a headhunter.

Perhaps Professor Liu Huanglong was now in a difficult position due to Professor Ni Yaoping's actions. Therefore, after re-entering the training room, Professor Liu Huanglong did not treat Fang Ziye as a subordinate at all, but instead unleashed a barrage of attacks with full force.

Professor Liu Huanglong cut the tail of a naked mouse into six sections.

Note that it was the tail that was cut into six pieces, not the tail artery.

Therefore, what Liu Huanglong performed on Fang Ziye was not just the suturing of the severed tail artery, but a tail replantation procedure.

It can be seen that Professor Liu Huanglong's suturing skills are quite high!
It took him about an hour and a half to reconnect all six broken tail sections!
Inside the 808 training room, the control panel displayed more professional assessment data.

"Immediate blood flow rate 98%!"

Blood flow rate: 0.22-0.26 ml/min! (milliliters per minute)

"Re2200-2500!"

Turbulent volume ratio: 12%

"Bleeding: None!"

"NCV: 30-35 m/s!"

"APA: 12-20mV!"

"..."

The overall patency rate of the blood vessels reached 98%. This is the overall patency rate of blood vessels after suturing multiple segments, which is already a very high level.

After suturing six segments, the overall patency rate of the blood vessels between each pair of segments is multiplied, resulting in a staggering 98% patency rate!
The result of multiplying five 99%s is definitely lower than 98%. To get a product of five percentages that is approximately equal to 98%, the required patency level of each pair of blood vessels is extremely high.

Among them, there were even more data points that Fang Ziye couldn't quite understand.

Fang Ziye felt a slight headache coming on; the data analysis in this advanced training room was far too professional!

Fang Ziye, a top student in trauma surgery, was completely bewildered.

But if you don't understand, ask. Before Fang Ziye could even speak, someone took the initiative to give him a half-explanation, half-flattery of Liu Huanglong: "Professor Liu, I suppose our hospital's Ziye rarely comes to the hand surgery practice room, so he doesn't really know the specific meaning of these data!"

Fang Ziye nodded: "Teacher Guan, Teacher Liu, I can only understand the blood flow rate and blood flow speed. The other data are really a bit baffling!"

Guan Qiquan, an associate professor, is currently the only one who can speak with authority besides the other professors. He said, "The speed of blood circulation is not necessarily better the faster it is, nor is it better the slower it is. Rather, it should be as close as possible to the normal value of the tail artery in nude mice."

"The theoretical value for the caudal artery in nude mice is 0.2-0.3 mL/min."

"However, there are several types of blood flow states. Laminar flow refers to the blood flow state in which the flow velocity distribution can be predicted in a layer parallel to the blood vessel wall. This flow form is idealized and is a fairly good approximation of the flow distribution in small blood vessels throughout the human circulatory system."

"When a blood vessel ruptures, if there is a narrowing at the suture site, the laminar flow breaks apart, forming turbulent flow or eddies. This is very similar to a river."

To make sure Fang Ziye could understand, Guan Qiquan also used real-life examples to explain.

“The calculated value of the dimensionless parameter Reynolds number Re can be used to predict turbulence. A value of Re less than 2000 predicts that the flow will be laminar, while a value greater than 2500 usually indicates that the flow will be turbulent.”

Guan Qiquan continued to explain: "Professor Liu can control Re within the range of 2000-25000. Now you can roughly understand how amazing that is, right?"

"However, although the overall Re assessment is not turbulent and eddy, eddies and turbulence can actually occur in the localized areas after damage."

"Eddies are localized eddies or stagnant blood flows that are separated from the central streamlines within a blood vessel. These eddies, also known as flowing eddies, often appear at the bifurcation of blood vessels and distal to narrow areas. They usually flow against the mainstream direction."

"The proportion of turbulence in the whole will, to some extent, reflect your condition. Most generally, if the occurrence of turbulence and eddies is relatively high, it is easier to cause blood clots."

"The reason why blood clots easily form in the heart is due to turbulence and eddies. This can be measured using ultrasound..."

"The smaller the ratio of turbulence to eddy current, the better. The ratio of turbulence to eddy current in normal blood vessels is 1%-3%, while it is 1% in the tail artery of nude mice."

"In normal cases, the percentage is generally 20% to 30%, and then gradually decreases to about 10%."

"After Professor Liu's suture surgery, the turbulent eddy current ratio was only 12%. After recovery, this ratio will be even lower, reaching 8% or even 7%!"

"To reduce it from 10% to 8%, the effort required is several times that required to reduce it from 100% to 10%."

"Nerve conduction velocity is NCV: Under normal circumstances, the conduction velocity of the rat tail nerve should be in the range of 25-50 m/s."

"The amplitude of the action potential is the APA, the sensory nerve conduction velocity (SNCV), the motor nerve conduction velocity (MNCV)..."

Guan Qiquan's tone was not exaggerated, nor did he exaggerate any emotion.

But such achievements, even when described using only the most objective data, have already exceeded the limits of most people's thinking!

For ordinary people, it would take a lot of effort to remember the specific meanings represented by these data, let alone keep all of these data within a normal range.

After listening, Professor Liu Huanglong said modestly, "Brother Guan, don't exaggerate my abilities. The level you mentioned is something that professors at Shanghai Sixth People's Hospital and Huashan Hospital might be able to match."

"I'm still a rank away from being ranked higher."

"Anyway, we're just killing time. In front of such a big shot, we're all just chickens fighting each other. Ziye, even though you come from a trauma surgery background, you're still part of our orthopedic family."

“Learning more and trying more is never wrong. I heard that you have done this tail artery suturing before. If you can’t do this tail reconnection well, then just do the nerve and blood vessel suturing!” “I’ll personally assist you…” Professor Liu Huanglong said, and personally cut off Fang Ziye’s tail.

It was also cut five times, including the part inside the body, making a total of six pieces.

Upon hearing this, Fang Ziye explained, "Professor Liu, this opportunity is certainly very valuable, but before I begin, I must apologize. I am currently the chief resident, and if there is an urgent consultation, I may have to discard the needle holder."

"After all, I have a mission to complete!"

Even though Fang Ziye had just upgraded his suturing skills to level 5 and was very confident in his suturing abilities, seeing so much professional data that he didn't particularly understand made him feel uncertain.

If Professor Liu Huanglong is blaming him for meddling, Fang Ziye would rather apologize now.

But now that things have come to this point, where is there any room for Fang Ziye to back down?
"A mission is a mission. Family matters cannot interfere with clinical work, let alone learning and performing in the practice room?"

"Medicine doesn't tolerate flashy techniques, but the training room certainly does!"

"Come on, Brother Guan, why don't you help Ziye with the procedure? We can also learn about tail replantation in mice!" Liu Huanglong's tone remained humble.

Although Guan Qiquan is an associate professor, he is older than Liu Huanglong.

Liu Huanglong has been calling him Brother Guan since Guan Qiquan was very young, and continuing to do so now is not considered shameful.

Upon hearing this, Guan Qiquan nodded and reluctantly began to operate the machine.

In any case, he has served as a background figure and foil for Liu Huanglong more than once or twice, and for more than a year or two.

As long as the leaders and professors don't embarrass themselves in public, it's fine.

Currently, Liu Huanglong's suturing skills are unparalleled below the "Transcendent" level. Apart from a few professors who can suppress him, others, including the most senior professors and Ni Yaoping who is currently at his peak, can only suffer a regrettable defeat.

Fang Ziye was actually just a figurehead who was brought in. He was both Liu Huanglong's excuse for delaying the time and a buffer for the hand surgery department to delay the time.

Therefore, most people turned their attention to where Guan Qiquan was.

Guan Qiquan lived up to expectations, teaching while demonstrating, treating it as a class. He focused on steady operation rather than striving for the same level of performance as Professor Liu Huanglong.

Of course, this includes people other than Zhu Weiguo!

Zhu Weiguo made the promise with Fang Ziye on his side, and he didn't tell any outsiders, including Wen Dongfang.

Liu Huanglong was once one of us, but now he is an outsider. However, Fang Ziye will always be a part of Zhongnan University. Therefore, there is no need to make Fang Ziye's outrageous remarks public in advance.

If Fang Ziye cannot defeat others with his strength, then these arrogant words should never be spread.

If Fang Ziye can suppress others with sheer force, then even if this arrogant statement doesn't exist, someone will naturally attribute it to Fang Ziye's title.

Wen Dongfang didn't need to know about the agreement between Fang Ziye and Professor Zhu Weiguo.

When suturing techniques reach the advanced level four, the surface appearance of the sutures becomes so similar that it's difficult to tell the difference; they are all very effective.

The differences in details are not something that can be judged by the naked eye.

Fang Ziye's suturing speed was even faster than Guan Qiquan's.

Even at the fastest pace, it still took nearly forty minutes to suture the nerves and blood vessels of the six tail segments.

Moreover, just as Fang Ziye was about to finish suturing, the resident's old-fashioned telephone rang.

"Drip drip drip drip!"

"Drip drip drip drip!"

The sound combined with the vibrations creates a very mesmerizing effect.

Someone nearby glanced at the note for Fang Ziye and said, "Senior Brother Fang, it's the emergency room's phone number..."

Fang Ziye picked up the needle, quickly finished the last stitch, and tied the knot as fast as he could!

Without cutting the stitches, he threw away the instruments in his hand, quickly took off his gloves, and pressed his ear to the old-fashioned resident's cell phone: "Trauma Surgery, okay!"

"Destroy or damage it, huh? Fine."

"Coming right away!" Fang Ziye had already taken off his gloves.

I took the phone from a junior hand surgeon, hung up first, and then said, "Excuse me, everyone, I'm sorry to bother you!"

"It's alright, you can go ahead and do your work." Professor Liu Huanglong said from the side, seeing that the goal of stalling for time had been achieved, and that it was already past four o'clock.

In a little while, I can escape by picking up my baby.

Fang Ziye had already run out, not daring to delay the urgent consultation.

However, shortly after Fang Ziye left the training room, various data appeared on the control panel where Fang Ziye was located.

Everyone left with smiles, but their faces were stiff and they felt terrible. All the sounds, including chatting, talking, flattering, gossiping, and so on, came to an abrupt halt...
