Chapter 124 The title hasn't been chosen yet! (Bonus chapter for 3000 monthly votes!)
June 9th, cloudy.

Lu Cheng received a call from Professor Zhong Junyun at 7:30 a.m.: "Xiao Lu, get ready. There's an emergency case of hemilimb replantation. Come to the operating room and come with me."

Lu Cheng never thought that Zhong Junyun would fail to get his contact information, but he never expected that Professor Zhong Junyun would take the initiative to contact him.

Lu Cheng stopped at the entrance of the ground-level parking lot of the experimental building: "Teacher, what about my class?"

"You won't be participating in the teaching surgeries later. There are only two surgeries on one operating table. How many people can fit in there?"

“What Lan Hualuo can teach you during her teaching surgeries, I can teach you too. Come over here, and I’ll send you the emergency operating room number in a bit.” Zhong Junyun hung up the phone after saying that.

He did not ask Lu Cheng's opinion, but instead very domineeringly and proactively changed Lu Cheng's 'study' schedule on the spot.

Mu Nanshu quickly said, "You should go right away. Professor Zhong's expertise in hand surgery is probably even better than Professor Lan's."

"He'll give you one-on-one instruction, a privilege usually reserved for associate professors in hand surgery..."

"Even if it's compensation, take it if you can. Professor Zhong doesn't owe you anything."

Lu Cheng nodded: "Okay."

Lu Cheng slowly started the car. Since it was Saturday, there were some people heading to the experimental building, but not many!

"I'm not hesitant about whether to go or not, I'm just wondering if I'm qualified to be valued so highly by Teacher Zhong."

Lu Cheng kept the car speed steady at around 40 miles per hour, speaking cautiously: "After all, my opportunities haven't been very good over the years."

Mu Nanshu said, "Is there anything else you have that Professor Zhong would covet? Don't think so much..."

"okay."

"As for lunch this afternoon, we'll have to see how things go," Lu Cheng said as he slowed down the car when the secondary toll gate in the ground parking lot opened.

"I can handle it myself." Mu Nanshu knew that Lu Cheng might invite Professor Zhong Junyun to dinner.

……

Following Professor Zhong Junyun's information, Lu Cheng inquired all the way to the 9th emergency operating room.

Lu Cheng, fully dressed in scrubs, stepped open the airtight door of the operating room. The sound of rolling wheels filled the air as his vision was opened.

Lu Cheng realized that he didn't recognize anyone in the operating room, not even Professor Zhong Junyun, and began looking around.

Lu Cheng looked around for a while before Zhong Junyun's voice came: "Lu Cheng, wash your hands... come up on stage directly."

Lu Cheng then realized that Professor Zhong Junyun had already taken the stage. At this moment, he was facing away from him, and those standing and surrounding him were likely people from the operating room or other people from the hand surgery department.

Lu Cheng immediately withdrew and began to wash his hands properly.

Wearing a sterile surgical gown and gloves, with his hands crossed over his chest, Lu Cheng slowly moved to the patient's leg area next to the operating table, found a seat, and sat down, his eyes as gentle as a beauty.

"Xiao Pan, move aside, I'll take Xiao Lu to perform this surgery." Zhong Junyun instructed as soon as he saw Lu Cheng approaching.

"Alright, Master." The man called Xiao Pan glanced at Lu Cheng and stood up to offer his seat.

"Thank you, Teacher Pan," Lu Cheng said shrewdly, seizing the opportunity.

“Call me Brother Pan…” Pan Leiming replied instinctively, then realized, “No, Brother Lu, you can call me Little Pan.”

Pan Leiming is only 28 years old this year, even younger than Lu Cheng, but he graduated early and became the chief resident because he was qualified.

"Hello, Brother Pan." Lu Cheng dared not listen to Pan Leiming.

"Stop with the 'brother' talk, get to work. This is a partial upper arm injury, no fracture, it's a perfect case of hemiplegic replantation..." After briefly explaining the situation, Zhong Junyun continued:
"Xiao Lu, there's no nerve damage, only ruptured blood vessels and muscles. It's a good time to test your basic skills."

"Vascular sutures." Zhong Junyun didn't even specify the type, directly ordering the circulating nurse.

"One 7-0 Johnson & Johnson vascular suture is on the table." The circulating nurse reported in detail while opening the suture pack.

Lu Cheng smoothly used the needle holder to hold the suture, adjusted the holding angle of the suture slightly, placed it in the curved tray, and then began to carefully search and read the surgical field of view with micro forceps.

This wasn't taught by Zhong Junyun, but rather by Professor Deng Yong of the Trauma Surgery Department at Zhongnan Hospital, who often taught Lu Cheng when he was there.

Furthermore, it is advised that no matter who asks you to come to the operating room or instructs you to perform any procedure, do not attempt to operate without carefully reading the surgical field. Operating without understanding is a major taboo in surgery.

Lu Chenggang was completely bewildered when he arrived, having not yet had the opportunity to work with Professor Zhong Junyun and others to stop the bleeding.

As Lu Cheng searched carefully, he indeed found a clue.

The surgery wasn't even completely finished because Lu Cheng discovered some unknown impurities, and he didn't know what they were!
Seeing this, Lu Cheng quickly used tweezers to pick it up and put it into another curved tray, next to the foreign object that had been cleaned out earlier.

Lu Cheng looked up at Zhong Junyun: "Professor Zhong, what is the injury mechanism of this patient?"

Different injury mechanisms require varying degrees of meticulous debridement; it is certainly not a simple sharps injury or a serrated wound.

Although he didn't know Professor Zhong Junyun's real purpose in telling him to directly suture blood vessels, Lu Cheng had more faith in his basic surgical knowledge.

“Abrasion from a sharp object!” Zhong Junyun said.

Lu Cheng's eyes darted around for a moment, then he continued searching for foreign objects, and he also examined the bleeding points in great detail.

After removing two more irregular foreign objects, Lu Cheng said, "Teacher, I think the wound is clean and we can rinse it now."

Lu Cheng did not act on instinct.

If he acted on instinct, Lu Cheng should have felt that Professor Zhong Junyun wouldn't use a patient as a test to see if he was careless enough.

But it's not impossible. If you start suturing it yourself, the ulnar styloid process might get damaged.

“Hmm…okay…” Zhong Junyun nodded.

Lu Cheng then rinsed the wound multiple times with saline, hydrogen peroxide, diluted complexed iodine, and saline.

After wiping the wound clean with a cotton pad again, Lu Cheng began to examine the severed blood vessel ends.

Brachial artery injury: The brachial artery is a medium-diameter artery, so suturing is not difficult and the requirements for suturing are not very strict.

After all, the finer the blood vessel, the more difficult it is to suture.

After hesitating for a moment, Lu Cheng still asked, "Teacher, I've never sutured the brachial artery before. Should I start suturing?"

Zhong Junyun thought for a moment and said, "Then you can give it to Xiao Pan later."

"Now remember this order: for limb replantation, as long as the patient's injury was not long ago, it is bone, tendon, vein, artery, nerve, and skin."

"The bones provide structural strength and the core framework; tendons are the vascular bed; arteries and veins are responsible for the survival of severed limbs."

"If the ischemia lasts longer, the arteriovenous suture sequence will take priority over the fracture fixation." Zhong Junyun did not scold Lu Cheng, but was just teaching.

"Okay, teacher." Lu Cheng sniffed, realizing he had finally fallen into a trap.

The main problem was that Professor Zhong Junyun had dug a trap within a trap, which Lu Cheng, who was not a specialist in hand surgery, really couldn't avoid.

"Can tendon sutures be done?" Zhong Junyun asked.

“Yes, I can!” Lu Cheng replied.

"So how do you plan to sew it?" Zhong Junyun continued.

"The biceps brachii with a large muscle belly, simple interrupted suture; the coracobrachialis tendon brachii woven suture; the long head of the triceps brachii with simple interrupted suture..."

After Lu Cheng finished answering, he added, "Actually, other suturing methods can also be used."

"Hmm?" Zhong Junyun was initially quite satisfied with Lu Cheng's answer, but upon hearing Lu Cheng's unexpected complication, he couldn't help but grunt in response.

"The coracobrachialis tendon is well-suited for a combined weaving and suturing technique," Lu Cheng suggested.

"What's the name?" Zhong Junyun racked his brains. Improved Tang method? Tsushita? Tajima.

Lu Cheng swallowed hard, but decided to say it anyway: "That teacher hasn't gotten up yet."
