Zhang Shuping shook his head, confirming: his uncle was not performing the surgery; his uncle’s student, Doctor Du, was.

"How can you see your uncle perform surgery?" Du Mengen asked.

"Luck." Zhang Shuping provided a precise answer, aiming to witness a top industry expert in action—unless you have the luck to force these experts to take the field yourself.

"Has anyone gotten lucky?" Du Mengen asked again, feeling it was incredibly difficult to gain the opportunity to see Zhang Huayao perform surgery.

"Yes." Zhang Shuping said.

"Who?"

Zhang Shuping pointed to Xie Wanying who was standing in front. As he knew, the last time his uncle was forced to personally step onto the operating table was at the dental hospital to save a child, marking the first time in years. The only medical student fortunate enough to witness it was Student Xie.

It was her again. Du Mengen adjusted his glasses and looked at Student Xie, unsure how to describe the mixed feelings in his heart.

"Have you eaten yet?" Shim Youhuan asked, showing care for his junior students.

Xie Wanying and Geng Yongzhe nodded.

"Teacher Du, let’s go take a break." Shim Youhuan invited Du Haiwei to the office.

After the patient was sent to the operating room, they had to wait for the anesthesiologist to administer anesthesia before the surgeon could proceed.

Watching their teachers and senior head to the office for a sip of water, Xie Wanying and the other medical students didn’t dare to rest and followed behind the patient’s stretcher to help in the operating room.

Except for her, the others were unfamiliar because it was their first time in Guo Zhi Hospital’s operating room.

It happened that today, the operating room this patient was entering was the same one her cousin had surgery in last time. Xie Wanying assisted by introducing to Student Geng and others: "Next door is the control room. This is a hybrid operating room, capable of performing interventional surgery simultaneously. In the corner is the heart-lung machine, and later when cardiac surgery is performed, there should be teachers from the extracorporeal circulation department present."

The anesthesiologist was busy, and the medical students stood to the side, not daring to get too close.

Du Mengen wasn’t idle; he walked around observing the machines Student Xie had mentioned, taking the opportunity to sneakily uncover the heart-lung machine while the teachers weren’t noticing. These couldn’t be seen at Beidou Third Hospital. Beidou Third lacks a cardiac surgery department, unable to perform heart surgery. Such specialized departments like cardiothoracic surgery might not exist in many hospitals, including tertiary hospitals, mainly because cultivating specialized cardiothoracic surgeons isn’t easy.

Doctor Mo administered anesthesia to the patient. Since it was his first time performing lateral decubitus epidural anesthesia, he couldn’t get it right after adjusting for a long time.

That day, listening to what Student Xie said, he initially thought it was quite easy, just needed to find an angle between 15 and 30 degrees. Yet after fiddling for ages, for some reason, the patient’s blood pressure and heart rate weren’t stable.

Doctor Mo was about to wipe sweat off his forehead with his hand, when suddenly a light bulb went off in his head, and he turned to call Student Xie over: "What degree did you mention last time, come, help me adjust it."

Upon hearing the teacher’s call, Xie Wanying walked over. The others watched her adjust the angle. Even the nurses were curious, wondering what she could come up with.

When Doctor Mo adjusted, he directly moved the patient’s body in a straight line, back and forth, like cutting with a knife.

After moving over, Xie Wanying took several pillows and slowly fine-tuned the lateral angle of each part of the patient’s body. Even if it’s left-leaning, the lateral angles of each part of the body need to be differentiated.

Whether this adjustment had any effect, the numbers on the monitor quickly gave the answer.

Blood pressure 130/85, stabilized. Heart rate 92, stabilized. Breathing, no problem, 20.
