Rebirth of a Doctor Without Regrets

Zhu Chunhua gently rested her chin on his back, her voice soft and tinged with concern as she asked, "What's wrong? Why are you standing here looking so worried?"

Wang Xiao gently patted her arm, his tone deliberately relaxed: "It's nothing, no rush."

Zhu Chunhua gently shook her head, rubbing her cheek against his back, her voice carrying a hint of coquettishness and a touch of seriousness: "You're lying, you're clearly anxious, it's written all over your face."

Wang Xiao, have you forgotten? You promised me that we would be completely honest with each other about everything related to medicine, and that we would solve any difficulties together.

Wang Xiao was stunned when she heard this. Her mind raced, but she couldn't remember when she had promised her that.

Was it during the last time the two of them were intimate after drinking and were not in their right minds?

Or was it a promise made impulsively when the two were deeply in love and exercising together?

Hearing his bewildered expression, Zhu Chunhua couldn't help but chuckle softly and tighten her grip on his arm.

"Whether you remember or not, you promised me. Tell me quickly, what happened? Is there some difficulty with the bypass surgery?"

Seeing Zhu Chunhua's gentle yet persistent demeanor, Wang Xiao's guard instantly dropped, and he no longer concealed any of his anxiety and helplessness.

He sighed softly, turned around, and looked into Zhu Chunhua's clear eyes: "Alright, I won't lie to you anymore. I've never performed bypass surgery before, and I don't even have any relevant practical experience."

I was trying to contact one of my former gifted classmates to get some video footage and notes from a bypass surgery, but when I called, he said he was in surgery and I couldn't reach him. I'm getting a little anxious.

Upon hearing this, Zhu Chunhua revealed a sly smile. She tiptoed closer to Wang Xiao and asked coquettishly, "Oh? Genius classmate? Boy or girl?"

Wang Xiao was taken aback, not expecting her to ask this, then smiled helplessly, "This is outside the realm of medicine. Anyway, it's just a classmate who has the information I need."

"Hmph, you dare to hide it from me! If you don't tell me, you're a female classmate!" Zhu Chunhua snorted, and taking advantage of Wang Xiao's inattention, she reached out and pinched his butt hard.

"Hiss—" Wang Xiao was caught off guard and gasped as he was pinched.

His voice was full of grievance, "Chunhua! What are you doing! You're squeezing me so hard, are you trying to kill me?!"

Seeing him wince in pain, Zhu Chunhua's anger subsided considerably, and she couldn't help but laugh out loud, gently patting his back.

"Serves you right for being dishonest and daring to hide things from me! It'll hurt, that'll teach you a lesson. Next time you dare to lie to me, see how I deal with you!"

Wang Xiao rubbed the spot where she had been pinched, looked at her bright smile, and sighed softly, "Okay, okay, I was wrong. I won't hide it from you again next time, alright?"

Zhu Chunhua reached out and took his arm: "That's more like it. But you don't need to rush to ask any classmates for information. It's no big deal, I can teach you, right?"

"Chunhua, are you capable of performing coronary artery bypass grafting?"

He knew, of course, that Zhu Chunhua had exceptional research capabilities, but this kind of complex and difficult surgery was her weakness.

Moreover, their team had never performed this type of surgery before.

Zhu Chunhua raised her chin, her tone tinged with arrogance: "Otherwise what? Do you really think all I can do is write papers?"

As she spoke, she took Wang Xiao's hand and turned to walk towards the elevator. "Come on, let's go to the simulated operating room in the practice room now. Before the surgery this afternoon, I'll let you familiarize yourself with the operating procedures so that you can get the hang of it."

Wang Xiao was pulled along by her. Zhu Chunhua's hand was soft and delicate, yet it carried an undeniable strength. "Okay, Deputy Director Zhu."

The two quickly entered the elevator and headed straight for the cardiac surgery training room.

The equipment here is almost identical to that of a real operating room, complete with operating tables, shadowless lamps, and all kinds of instruments.

Zhu Chunhua walked to the refrigerator, took out a fresh pig heart, and then took out a tray and a set of bypass surgery instruments, placing them one by one on the operating table.

"You take over the operation. Do as I say. First, familiarize yourself with the anatomy of a pig's heart, which is very similar to that of a human heart. Focus on the distribution of the coronary arteries."

Wang Xiao immediately stepped forward, put on sterile gloves, and focused his gaze intently on the pig's heart.

Although he had never performed bypass surgery, he had a solid foundation in cardiac anatomy. With a gentle touch of his fingertips, he quickly located the general course of the coronary arteries in the pig's heart.

Zhu Chunhua stood beside him, adjusting the shadowless lamp to precisely focus the light on the blood vessels.

Her tone instantly became serious and capable, the previous coquettishness gone: "First question, this afternoon we're doing tricuspid valve replacement combined with coronary artery bypass grafting. Which of these two procedures should we do first?"

Without the slightest hesitation, Wang Xiao blurted out, "Build a bridge first, then replace the petals."

Although he didn't understand the deeper logic, he had seen similar surgical sequences sporadically in the literature before, and gave the answer based on his memory. After speaking, he still subconsciously looked at Zhu Chunhua, with a hint of uncertainty in his eyes.

"The answer is correct," Zhu Chunhua nodded slightly, but her tone became more serious. She reached out and gently tapped the myocardial part of the pig's heart. "But I ask you, why do we need bypass surgery first, and then valve replacement?"

Wang Xiao frowned slightly, feeling somewhat embarrassed. Her fingertips unconsciously tightened around the instruments in her hands: "I...I don't know. I've only vaguely seen the order of related combined surgeries in the literature, but I didn't pay attention to the reason."

Seeing this, Zhu Chunhua felt no pressure from her superior doctor; instead, she softened her tone and patiently explained.

"This is the core principle of cardiac surgery: prioritize treating lesions that threaten the myocardium, and then treat valvular lesions that affect cardiac function."

You see, coronary artery blockage can directly lead to myocardial ischemia and hypoxia. If valve replacement is performed first, the myocardium will be ischemic for a long time during the operation, which can easily cause myocardial infarction or even cardiac arrest. The risk is too great.

Performing bypass surgery first can quickly restore blood supply to the myocardium, paving the way for subsequent valve replacement and reducing surgical risks.

These words were clear, logical, and easy to understand. Wang Xiao nodded repeatedly, "I see, I understand now."

Zhu Chunhua smiled smugly and continued to test him: "Good that you understand. Now, let me ask you another question: the core of bypass surgery is the anastomosis of the graft vessels. Which end of the graft vessels should be anastomosed first? The proximal end or the distal end?"

This question completely stumped Wang Xiao. He shook his head slightly and said frankly, "I really don't know. I've never had any practical experience with this, and I haven't even heard any related explanations."

"Remember this, anastomose the distal end first," Zhu Chunhua picked up an artificial graft and handed it to Wang Xiao, pointing to the coronary artery.

"First, suture one end of the bypass graft to the distal end of the narrowed coronary artery. Here, it is important to ensure that the stitches are even, the anastomosis is tight, there is no leakage, and the vessel wall is not damaged."

Wang Xiao listened attentively to her explanation while stitching.

"After the distal anastomosis is completed, the proximal anastomosis is performed to suture the other end of the bypass graft to the aortic wall."

The so-called coronary artery bypass grafting, also known as bypass surgery, does not work by unblocking the blocked blood vessel, but by using another blood vessel to bypass the blocked blood vessel.

This is similar to a section of a water pipe being blocked by a foreign object. If the blockage is difficult to remove, you can drill holes in front of and behind the blocked section and connect a U-shaped tube to allow blood to bypass the blockage and pass through the U-shaped tube, thus restoring smooth flow.

Bypass surgery allows blood to reach the heart muscle through bypass vessels, restoring normal blood supply to the heart muscle.
