If it weren't for a lot of coincidences, Fang Ziye would definitely not have had the opportunity to contact a boss of Professor Liu Huanglong's level.

If it weren't for Professor Liu Huanglong's chance of using Fang Ziye to drive the tiger and wolf, Fang Ziye would not have had the opportunity to talk to Professor Liu Huanglong at all, and even think about starting a headhunting job.

Maybe it's the current Professor Liu Huanglong, who was also made a little difficult by Professor Ni Yaoping, so after re-entering the practice room, Professor Liu Huanglong's performance did not treat Fang Ziye as a subordinate at all, but was an output with full firepower.

The tail of a nude mouse was cut into six pieces by Professor Liu Huanglong.

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

Therefore, what Liu Huanglong operated on Fang Ziye was not only the suturing of the broken tail artery, but the replantation of the broken tail.

It can be found that Professor Liu Huanglong's level of suturing is quite high!

It took him about an hour and a half to renew all six broken tails!

In the operation console in the 808 practice room, more professional evaluation data flashed.

"Instant blood patency rate of 98%!"

"Through-blood rate: 0.22-0.26ml/min!"

“Re2200-2500！”

"Turbulent volume ratio: 12%"

"Bleeding: None!"

“NCV：30-35m/s！”

“APA：12-20mV!”

“……”

The overall patency of the blood vessels reached 98%. This is the level of comprehensive vascular patency after multi-segment vascular suture, which is already quite high.

The six segments were sutured, which is equivalent to the product of the overall patency rate of the blood vessels between each two segments, and finally obtained a terrifying data of up to 98%!

The result of the multiplication of five 99% is definitely less than 98%, and the product of the five percentages is about equal to 98%, and the level of vascular patency required for every two segments is very high.

Among them, there are many more data that Fang Ziye can't particularly understand.

Fang Ziye faintly felt a little headache, the data evaluation in this advanced practice room was too professional!

Fang Ziye, a top student of authentic trauma surgery, is buzzing at the moment.

But if you don't understand, just ask, but before Fang Ziye could speak, someone took the initiative to give Fang Ziye half science popularization, and half patted Liu Huanglong's ass: "Professor Liu, presumably the Ziye of our hospital rarely comes to the hand surgery practice room, so they don't particularly know the specific significance of these data!" ”

Fang Ziye nodded: "Teacher Guan, Teacher Liu." I can understand the blood patency rate and blood flow rate, and the other data is really a bit confusing! ~”

Guan Qiquan is an associate professor, and at present, he is the only one who can speak except for the professors, so he said: "The speed of blood passage is not the faster the better, nor the slower the better. Rather, it should be closer to the normal value of the tail artery in nude mice. ”

"The theoretical value of the tail artery in nude rats is 0.2-0.3 mL/min (milliliters per minute)."

"But there are several states of flux, and laminar flow refers to the state of blood flow in layers parallel to the walls of blood vessels that predict the distribution of flow velocities. This form of flow is idealized and is a fairly good approximation of the flow of small vessels throughout the human circulatory system. ”

"When a blood vessel is ruptured, when there is a stenosis at the suture site, the laminar flow breaks off, forming turbulence or vortex. It's a lot like a river. ”

In order to make Fang Ziye understand, Guan Qiquan also used examples from life to explain.

"Turbulence can be predicted by the calculated value of the dimensionless parameter of the Reynolds number Re, a value of Re less than 2000 predicts that the flow will be laminar, and a value greater than 2500 usually indicates that the flow will be turbulent."

Guan Qiquan continued to explain: "Professor Liu can control Re in the range of 2000-25000, you can roughly understand how powerful this is now, right? ”

"However, although the overall Reassessment is not turbulence and vortex, in fact, eddy currents and turbulence will occur locally after injury."

"Vortex is a local vortex or stagnant blood flow that is separated from the central streamline within the blood vessels. This vortex, also known as a flow vortex, often occurs at the bifurcation of blood vessels and distal to the narrowed area. Usually counter-current with the main direction. ”

"The proportion of turbulence in the whole will insinuate your good or bad to a certain extent, and the most conventional, if the incidence of turbulence and vortex is relatively high, it is easy to produce blood clots."

"The principle of blood clots in the heart is turbulence and vortex. Ultrasound can be used to measure ......"

"The ratio of turbulence to vortex is as small as possible, and the proportion of turbulence and vortex in normal blood vessels is 1%-3%, and the proportion of turbulence and vortex in nude rats is 1%."

"Normally, after surgery, it's generally 20 to 30 percent, and then it gradually drops to about 10 percent."

"After Professor Liu's suturing, the turbulent vortex accounted for only 12%, and after recovery, this ratio will be even lower, reaching 8 or even 7 percent!"

"To go from 10 percent to 8 percent, the effort required is several times greater than 100 to 10 percent."

"The nerve conduction velocity is the NCV: in general, the conduction velocity of the rat tail nerve should be in the range of 25 to 50 m/s."

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

Guan Qiquan's tone was not exaggerated, and he did not increase any emotion.

But such an achievement, which only needs to be described by the most objective data, has exceeded the upper limit of most people's thinking!

Ordinary people, if they want to remember the specific meaning of these data, they need to spend a lot of energy, not to mention that all these data are controlled within the normal data range?

After listening to this, Professor Liu Huanglong said a little modestly: "Brother Guan, don't too hard, the level you are talking about, if it is those professors from the Sixth Hospital of the Demon Capital and Huashan Hospital, it is possible." ”

"I'm still a rank."

"Anyway, it's okay to be idle, in front of such a big guy, everyone is pecking at each other. Ziye, although you are from trauma surgery, you are still our orthopedic family. ”

"Learn more and try more, there is nothing wrong with it, this suture of the broken tail artery, I heard people, you have done it before, then this broken tail connection, if you are not good at completing it, you will only complete the nerve and blood vessel suture!"

"I'll personally match you with a ......," Professor Liu Huanglong said, and personally cut Fang Ziye's tail.

It was also cut five times, and the section included in the body was exactly six sections.

When Fang Ziye heard this, he explained: "Teacher Liu, this opportunity must be very precious, but before I start the operation, I still have to confess first, I am now the general manager of the hospital, if there is an urgent consultation, I may have to lose the needle." ”

"After all, there is a task on the body! ~”

Even if Fang Ziye had just increased the suture to level 5, he was very confident in his suture operation, but in front of so much professional data that he didn't particularly understand, Fang Ziye felt bottomless.

If Professor Liu Huanglong blamed him for being troublesome, Fang Ziye would rather apologize now.

It's just that now that they have reached this point, where is there room for Fang Ziye to retreat?

"The task is the task, and the family affairs must not be misplaced, let alone the learning and performance in the practice room?"

"Medicine can't show off skills, but the practice room can! ~”

"Come on, Brother Guan, let's accompany Ziye to operate it, and by the way, let's also learn about the tail replanting of mice again!" Liu Huanglong's tone has always been very modest.

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

Liu Huanglong called him Brother Guan, he started when Guan Qiquan was very young, and now he continues to call him like this, but he is not a humble person.

When Guan Qiquan heard this, he nodded, and then he started to operate.

Anyway, in front of Liu Huanglong, he served as a background board and a backdrop board more than once or twice, and more than a year or two.

As long as the bosses and the old professors don't lose face.

At present, Liu Huanglong's suturing technique is the first person under the 'transcendence', except for a few professors who can suppress it, others, including several old professors at the peak, including Ni Yaoping, who is now at his peak, can only regret defeat.

Fang Ziye was actually just a foil who was called, he was not only a reason for Liu Huanglong to delay time, but also a buffer for the hand surgery to delay time.

Therefore, most people are looking in the direction of Guan Qiquan.

Guan Qiquan also lives up to expectations, while operating, while teaching, the right is in class, the operation is only stable, not the effect of comparison with Professor Liu Huanglong.

Of course, the people in this, except for Zhu Weiguo!

Zhu Weiguo was pulling Fang Ziye aside before, and he didn't tell outsiders about the promises he made, including Wen Dongfang.

Liu Huanglong used to be his own person, and now he is an outsider, but Fang Ziye will always be a part of Zhongnan, so there is no need to make Fang Ziye's wild words public in advance.

If Fang Ziye couldn't use his strength to defeat others, then this wild word would never have to be spread.

If Fang Ziye could use hard power to suppress others, then even if this wild talk was not there, someone would naturally put it on top of Fang Ziye's title.

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

After the operation of suturing has reached the fourth level of 'entering the house', in fact, it is difficult to see any difference in the surface effect of suture, which is very strong.

The gap in detail is not appreciable to the naked eye.

Fang Ziye's stitching speed is even faster than Guan Qiquan's.

It's just that no matter how fast it is, it takes nearly forty minutes to suture the nerves and blood vessels of the six segments of the tail.

Moreover, just as Fang Ziye was about to complete the stitching, the old-fashioned phone of the general inpatient rang.

"Didi, Didi!"

"Didi, Didi!"

The sound and vibration are very magical.

Next to him, someone helped Fang Ziye glance at the remarks and said, "Senior Brother Fang, it's the phone number of the emergency department......"

Fang Ziye picked up the needle, quickly hooked the last needle, and tied the knot as fast as possible!

Then he didn't cut the thread, he threw away the instruments in his hand directly, quickly took off his gloves and at the same time, put his ear on the old-fashioned inpatient mobile phone: "Trauma surgery, good!" ”

"Ruined damage, huh? Yes. ”

"Come now!" Fang Ziye had already taken off his gloves.

Picking up the phone from a hand surgeon, he hung up first, and then said, "Excuse me, teachers, I'm sorry!" ”

"It's okay, you go get busy." Next to him, Professor Liu Huanglong saw that the current purpose of delaying time had been achieved, and now the time had reached more than four o'clock.

In a little while, I can pick up the cubs and run away.

Fang Ziye had already run out, and he didn't dare to delay the emergency consultation.

However, not long after Fang Ziye left the practice room, various data from the operating console where Fang Ziye was located surfaced.

Everyone walked away with a smile, their stiff faces were unbearable, and everyone's voices, including chatting, talking, flattering, flattering, gossiping, etc., all came to an abrupt end......
