Chapter 1194 Female PhD

Seeing the heart rate gradually decrease, Dr. Wei immediately reported it.

This is because the separation process affected the heart rate center. Song Ziming tried to control the manipulation as gently as possible, but it was still unavoidable.

"Use intermittent operation, don't rush, don't be afraid," Yang Ping told him.

At this time, if you can operate for a while and then rest for a while, try to shorten the time your heart rate stays at a low frequency. A heart rate that is too low can easily cause ischemia or cardiac arrest.

Currently, only Yang Ping can operate on this area without affecting the heart rate in the slightest. It is already remarkable that Song Ziming can prevent cardiac arrest. This is why the Americans recommend patients to him. If they were to perform the procedure, there is a high chance that the heart would stop beating.

Dr. Wei sat down and didn't say anything more. Although he was calm and composed, he hadn't seen many big scenes, so when he saw his heart rate drop to the critical value of 40 beats per minute, he felt a little panicked and scared.

The research institute can now perform two to three surgeries at the same time, but only two were performed today because Xu Zhiliang needed to come here to assist Song Ziming.

Fatty Liang made rounds in both operating rooms. If any patient in any of the surgeries was in danger, he could intervene immediately to save them. After all, he was the director of the anesthesiology department and had the most experience. During the surgery, the patient's life was entrusted to the anesthesiologist for monitoring.

Fatty Liang came in to make his rounds, and Dr. Wei reported to him, "Your heart rate just dropped to 40 beats per minute."

"Don't worry, this happens frequently during this type of surgery. Just remember the duration and report your heart rate every 30 seconds," Fatty Liang instructed.

He saw Professor Yang in the operating room and immediately greeted him, "Professor! Are you here in person to oversee the operation?"

Yang Ping nodded, and Fatty Liang stood beside him to watch the surgery for a while.

"How's the coronary artery bypass grafting going?" Yang Ping asked.

"It's alright, we've already put up two, and we're planning to put up four," Fatty Liang replied.

"Keep jumping over the bridge?"

"Yes."

Xia Shu seems to be making rapid progress. If he were still at the original hospital, how could he possibly be able to perform this kind of surgery now? He would probably only be able to be a first assistant at most, or he might not even be qualified to be a first assistant.

"The heart rate isn't going up. It was fluctuating a moment ago, but now it's stuck at 40 beats per minute. It even dropped to 35 beats per minute once, but then immediately rose back up to 40 beats per minute." Dr. Wei kept his eyes glued to the screen of the cardiac monitor, not daring to blink.

Yang Ping turned his head and glanced at it. It was indeed the case. If they couldn't get up there for a long time, it might be dangerous.

Song Ziming stopped what she was doing, looked away from the microscope's eyepiece, glanced at the monitoring screen, and then took a deep breath.

For him to have performed this much of the surgery is already quite remarkable.

Cavernous hemangiomas of the pons can usually be treated in many hospitals both in China and abroad. Generally, top-tier hospitals that can perform brainstem surgery can do it, but the results vary.

This cavernous hemangioma was a bit tricky, otherwise the Americans wouldn't have recommended Sanbo Hospital. Song Ziming was already mentally prepared, but she didn't expect the surgery to be more complicated than anticipated.

It's still not working; my heart rate is still 40 beats per minute. If this continues, something bad will happen sooner or later.

"Continue! Slow down, be careful, separate that 1-centimeter adhesion, and your heart rate will naturally go up," Yang Ping instructed Song Ziming.

"Ok!"

Song Ziming immediately rejoined the battle.

"When using the tweezers with your left hand, do not apply tension; use a tension-free separation technique," Yang Ping commanded.

In general surgical procedures, separation is usually performed under tension, which makes the operation easier. It's like cutting a piece of cloth; if you stretch the cloth taut, it's easy to cut. If the cloth is completely relaxed instead of stretched, it's very difficult to cut.

The same principle applies to surgery. By slightly pulling apart the target tissue to make it taut and under tension, it becomes much easier to separate, whether using a scalpel or scissors. Loose tissue is not only difficult to separate, but it is also more likely to cause accidental injury.

Tension-free dissection requires certain skills, especially in this type of situation, which is a fundamental skill in surgery.

However, in this situation, tension-free separation is clearly the optimal choice, because any tension caused by traction will affect the function of the surrounding nerves, and the current decrease in heart rate is caused by this traction tension.

If tensionless separation is used, another problem will arise: it will increase the difficulty and risk of separation, and it is extremely easy to cause accidental injury. Once accidental injury occurs, the consequences will be unimaginable.

However, based on Yang Ping's understanding of Song Ziming, his current surgical skills are sufficient to handle this situation; the only psychological challenge is that he needs to experience it independently.

The laser scalpel in Song Ziming's hand has a precision of 0.1 millimeters. Each cut is 0.1 millimeters deep or far. To cut 1 centimeter of adhesion, it would take at least 100 operations. This requires very skilled operation, with each cut being precise and without any repetitive, ineffective, or inefficient operations.

Yang Ping had already thought it over carefully and knew that Song Ziming could handle it, so he stood up and said, "I have something to do outside. You guys take your time. Call me if you need anything."

Actually, he went to the sink to wash his hands, deliberately saying he was leaving temporarily. This was to break Song Ziming's dependence on others when faced with such difficulties and to build his confidence in handling problems independently. If any problems really arose, he would be ready to step in and save the day after washing his hands.

"Professor, sit down for a while!" Song Ziming immediately stopped using the laser knife in his hand.

But Yang Ping pretended not to hear and walked away.

As soon as the surgery stopped, the patient's heart rate dropped again. Song Ziming had no time to pause and could only grit his teeth and continue the dissection, trying his best to stay calm and move forward step by step.

I dared not stop, nor dared to go too fast, as both would cause my heart rate to drop, so I could only grit my teeth and continue, proceeding cautiously.

Finally, Song Ziming completed this step of the procedure, and the patient's heart rate slowly returned to normal. At this moment, Yang Ping also came in: "How is it?"

"The adhesions you mentioned have separated." Sweat beaded on Song Ziming's forehead. He turned his head, and the circulating nurse wiped the sweat from his forehead with a tissue.

"Yes, next time you encounter this situation, don't panic. Stay calm. You are fully capable of handling it. In short, when separating in this area, try to minimize interference. The most easily overlooked interference is the tissue tension caused by traction during separation," Yang Ping summarized for him.

"I've got it!" Song Ziming kept Yang Ping's words in mind; staying calm was very important.

However, the more high-risk situations one experiences, the greater the likelihood of remaining calm. This is the reason why battle-hardened veterans are not afraid when they go to the battlefield.

The high-risk procedure was brief; it was over before even the anesthesiologist, Dr. Wei, had a chance to experience it. The atmosphere in the surgery returned to its relaxed and pleasant state, and everyone started chatting and laughing. Surgery is something surgeons do every day; it's no fun performing surgery in silence with a stern face all day. It's much better if we can talk about lighthearted topics.

"Who referred this patient?" Yang Ping just remembered that they said it was referred by Johns Hopkins Hospital.

Song Ziming said, "Massimo and Raymond, Raymond is Massimo's friend."

"Raymond, I've never heard of him before? Is he a member of our forum?" Yang Ping thought the name was quite unfamiliar.

“No, he wants to join, but the conditions aren’t right yet,” Song Ziming replied.

Yang Ping nodded: "Okay, I understand. You guys continue, I'm going to eat."

Song Ziming should be able to complete the next steps quickly, so Yang Ping doesn't need to worry. After leaving the operating room, he sat in the changing room for a while. He was all alone there, and it was very quiet. He leaned back in the chair and closed his eyes to rest.

After sitting in the changing room for a while, Yang Ping came out of the operating room and rushed to the laboratory. Many of the researchers in the laboratory were still there. In fact, Tang Shun encouraged them to rest and not to work overtime unless there were special circumstances.

But these people love doing scientific research. Even after get off work, they don't like to go out and wander around. Instead, they stay in the lab. Even when they play games, they have to play in the lab's break room to make it feel right. They play games until after 9 p.m. before going home.

This is what it means to make the laboratory your home.

Several PhD students in the lab, all graduates of Nandu Medical University, were talking about Guan Ruyan. They heard that Guan Ruyan was actually quite wealthy after going to the United States, and he also had experience living abroad, so he shouldn't be in such a miserable state. Apparently, he was swindled out of everything by a fellow villager, ending up homeless on the streets.

Unlike Chinese society, American society has a very low tolerance for mistakes at the grassroots level. Many things are interconnected, and once the economy collapses, a vicious cycle quickly forms, eventually leading to homelessness.

For example, houses in the United States may seem to have freehold ownership, but that's not actually the case. You have to pay property taxes every year. If you can't pay them, sorry, after a certain period of arrears, the house is no longer yours, and the court can forcibly seize and auction it off.

In addition, with the rampant drug problem in the United States, once people lose their jobs or encounter other economic difficulties, a series of interconnected problems follow one after another, like heavy chains. Once they feel hopeless about turning their lives around, they can easily fall into the self-numbing trap of drugs, and in this way, their whole life is ruined.

Guan Ruyan is probably in this situation, which is why there are so many homeless people in the United States. Several PhDs are analyzing this from a sociological perspective.

"Actually, Chinese society has a much higher tolerance for mistakes than the United States, especially among the lower classes. No matter what difficulties they encounter, such as unemployment, those from rural areas at least have a house and a piece of land when they return to their villages; they won't end up homeless or starving."

"It's pretty much the same in the city. As long as you're willing to work hard, you can still earn a living, such as delivering food, carrying bricks on construction sites, or doing other odd jobs. There are no barriers to entry, as long as you can endure hardship."

"Be careful of fellow countrymen when you're abroad. Many people have been taken advantage of by them, so sometimes you can't trust others too much."

"I heard that Guan Ruyan went to the United States and was sold out by a fellow villager who swindled all her money."

"If he hadn't wanted to take advantage of others, how could he have been fooled? I heard he used the same old trick to gain a foothold in the United States. I didn't expect that woman to be on the same side as him. She has had countless husbands, and each time she used marriage as a stepping stone. I never thought that the two kinds of people would collide. That woman just had the home-field advantage."

"I see. How did you know?"

"My senior colleague is in Los Angeles right now. Everyone in their circle knows about this. That woman is a repeat offender; she's scammed several people, and she's incredibly ruthless, always leaving them penniless."

"The one who flies eagles gets pecked by eagles; it's really true."

Lu Xiaolu is on vacation today and didn't come. Besides, this is a stem cell lab, otherwise these PhDs wouldn't be talking about these things. This is a sad thing for Professor Lu.

“Let’s not talk about these things,” one of the PhD students suggested angrily.

Everyone tactfully stopped talking, explaining that they had just gotten to this point in their conversation and the topic had suddenly become a hot one.

"I heard that our institute is recruiting a lot of people this year, including many who have returned from studying abroad. Many of them are from Tsinghua and Peking Universities and are pursuing their PhDs in the United States. Now they want to come to Sanbo Hospital."

"Yes, one of my senior classmates is inquiring about this place. Our institute has a great reputation in the United States, and many PhDs who studied in the US are interested in coming here."

"I heard that Professor Yang will be conducting the interviews in person. The interviews are sure to be very exciting. I'd like to go and see them too."

"How come Professor Yang's brain is so sharp? It seems like there's no book or paper he hasn't read. Does he read so fast that he can memorize everything after just one reading?"

"That's definitely true; we can't fathom the minds of geniuses."

"There's a guy named Cheng Yankun who graduated from Peking University. He went to the United States and is now the director of a lab there. He's only been out of school for a few years, but he's already published a ton of top-tier papers. He's really arrogant and often shuts people down in public, showing them no respect whatsoever. I heard he'll be coming this time too, but he definitely won't be doing a regular graduate interview; he'll be having a private chat with the professors."

"Are you talking about Cheng Yankun from Harvard Medical School? I heard he got into Tsinghua University at the age of fourteen and won the world championship in the Mathematical Olympiad?"

"Yes! It's him. I heard that when he graduated, he had an interview in the US and was speechless during the interview with the professor."

"Everyone has to keep their temper in front of a professor. I'm telling you, just you wait and see."

"When this kid comes here, he'll probably be the first person who can't answer a question he's asked."

Upon seeing Yang Ping enter, the doctoral students immediately stopped their casual conversation and all stood up to greet him: "Professor!"

Where is Dr. Tang?

Yang Ping went to Tang Shun's office but didn't see him.

"I heard they took Dr. Li to get an ultrasound. It's too crowded during the day, so they didn't have time to go. They asked the ultrasound department to let them go after get off work to get an ultrasound done separately," one of Tang Shun's doctors replied.

"Oh! Why aren't you guys off work yet?" Yang Ping asked, noticing that so many of them had gathered together after get off work.

"We're just chatting here. We're both homebodies who like to stay in the lab."

Yang Ping looked around and saw that they were all male. Last time he went to Nandu Medical University, a PhD student suggested that they should recruit more female PhD students, and even presented his dissertation as evidence.

Well, it seems our lab needs a certain number of female PhDs.

Yang Ping thought, "Let's take advantage of this recruitment opportunity to add some female researchers. This is a serious issue."
