Chapter 1492: 1445 Chainsaw Horror

"Su Yun, Old Zhao, you've put on the lead clothing, right?" Zheng Ren asked.

We've put them on.

Zheng Ren nodded and went straight to scrub up.

Actually, after going through the filter, normally you wouldn't step over the line. But Zheng Ren was also worried about unexpected situations; in the System Operating Room, many accidents have occurred.

Wearing dozens of pounds of lead clothing for surgery is hard work, but for Su Yun and Zhao Yunlong it's no big deal.

After returning and putting on their clothes, Hu Yan Hui put on the live-stream glasses, and the surgery officially began.

Zheng Ren made an incision in the middle of the sternum, starting just below the sternal notch and reaching about 5 cm below the xiphoid process.

Along the midline, he used an electrocautery to cut the sternal periosteum, separating the sternal incision down to the sternum; then he dissected the xiphoid process and the space behind the sternum. After removing the xiphoid process, Zheng Ren said in a low voice, "Electric saw."

The electric saw had already been prepared after solo sterilization; Xie Yiren handed the electric saw to Zheng Ren.

After a quick test, the buzzing sound echoed in the operating room.

"I haven't heard that sound in a thoracic surgery for a long time." Old He felt somewhat sentimental.

"It will become less and less common." Zheng Ren inserted the saw's head into the space below the dissected xiphoid, pressing it firmly against the sternum, and said, "Interventional surgery will perform all thoracic surgeries; that's the future trend."

Zhao Yunlong was somewhat unwilling to accept.

"There's also heart transplant and aortic arch replacement."

"Old Zhao, you're just being contrary." Zheng Ren's eyes narrowed slightly; as he lifted the saw a bit to avoid damaging the mediastinal tissues too much, he said, "Heart transplant isn't a major surgery. For the aortic arch… within ten years, type 1 can be treated with interventional stent placement."

"Is that even human talk? Heart transplant isn't a major surgery?"

"If it weren't for Zheng Ren standing in front of me,"

"if he weren't holding an electric saw……"

Zhao Yunlong wanted to curse outright.

Buzz…

The electric saw began to saw the sternum.

The sternal bone was sawn open, continuously spraying blood droplets and white bone fragments.

Zhao Yunlong and Su Yun loosely held white sterile gauze on the sternum to block the splatter.

"Boss, you're looking down on our thoracic department." Su Yun was displeased, "Lung transplant—I just don't believe you can do it with interventional surgery."

"Don't keep bringing up transplants; it's pointless." Zheng Ren held the electric saw, sawing the sternum at a moderate speed with a steady hand. The high-frequency vibration from the saw head striking the sternum did not affect the stability of his grip.

"It's like coronary artery bypass graft surgery is about to be phased out; in the future, all non-transplant surgeries will become minimally invasive. If you don't learn minimally invasive surgery, you'll be eliminated."

The electric saw's sound stopped abruptly; Zheng Ren took the sterile gauze Su Yun handed him, quickly wiped off the non-clotting blood and bone fragments on the saw head, and passed the saw to Xie Yiren.

He reached out, and the electrocautery appeared in his hand.

At the cut periosteum, he used electrocautery to stop the bleeding—several points, done with a series of snaps. A burnt smell spread; Su Yun and Zhao Yunlong didn't pause, already requesting bone wax and began to evenly apply it to the sternal bone.

Sawing the sternum, bleeding from the periosteum is stopped with electrocautery; bone itself can only be stopped with bone wax.

"Zheng Lao Ban, have you seen Chainsaw Horror?"

"I've seen it; except for the first episode, I didn't really like it." Zheng Ren said.

"Boss, I've cosplayed Chainsaw Horror. Yeah, it's surgical inspiration. But sometimes I'm afraid of playing too H; when I lose control during surgery, I start cosplaying Freddy from Elm Street." Su Yun said while applying bone wax to his hand.

"I haven't played it; I find it uninteresting. You wouldn't actually press that machine onto your own head, would you?" Zheng Ren used a retractor to open the sternum, performed blunt dissection, and exposed the heart.

"How could I? I'm not stupid." Su Yun said.

In the operating field, the heart beat thump-thump-thump. Su Yun reached in, probed with a finger, and said, "The heart is ischemic and hypoxic; its contractile force is weak."

"Hurry up, stop chatting." Zheng Ren said, reaching out as the willow-leaf blade slapped into his hand.

He made a longitudinal midline incision in the pericardium, extending upward to the reflection of the ascending aorta and downward to the diaphragm, then cut a side opening on each side of the lower incision to better expose the operating field.

Afterwards, Zheng Ren sutured the pericardial edge to the soft tissue outside both sides of the sternum, so that the assistants would have less work.

The surgery is major; not only the surgeon, but even the assistants must be extremely busy—six hands wouldn't be too many.

After opening the pericardium, Zheng Ren began the first step of exploration.

The objects of exploration were mainly the aorta, pulmonary artery, left and right atria, left and right ventricles, superior and inferior vena cava, and pulmonary veins.

The purpose was to examine the size, tension, and presence of thrill at these locations, and to check for the existence of the left superior vena cava and other extracardiac abnormalities.

Although Zheng Ren had performed countless checks in the System Operating Room, in the real world he still verified and checked once again.

Absolutely no room for the slightest carelessness!

The surgery was very standard, the process smooth, with no detail omitted.

Su Yun and Zhao Yunlong, these two capable of independently undertaking major thoracic surgeries, as assistants made the surgery speed increase dramatically.

Zheng Ren reached out and touched the tissue near the pulmonary valve, saying, "You feel it."

His tone was like that of an old professor on rounds, letting students experience the palpation of a certain disease.

"What did you feel?" Su Yun wondered, tapping Zhao Yunlong's radial styloid with his hemostatic forceps; taking advantage of his retracted hand, he placed his right index finger on the tissue near the pulmonary valve.

He didn't apply force, just a light touch, and Su Yun understood.

"Stable!" Su Yun said.

"What's stable?" Old He anxiously asked.

These two were playing riddles on the operating table, a highly unethical thing.

"The patient's diagnosis is clear: a pulmonary valve tumor, definitely not a large embolus." Su Yun said with a smile.

He retracted his hand, and Zhao Yunlong placed his finger on it.

"Mm, there's pulsation, it's soft, it's bodily tissue; the likelihood of a pulmonary valve tumor is high." Zhao Yunlong said more, in detail, as usual adding a couple of sentences so the junior doctors would remember, to later write the operative record.

But after saying that, Zhao Yunlong realized that, among the people on the operating table, the most junior doctor was actually himself!

To write the operative record, he could only do it himself.

Pointing at Su Yun to write it, he would surely have to turn against himself.

Damn, Zhao Yunlong silently cursed to himself.

……

Note: I have a friend, his artery catheter was not closed. Twenty years ago, when I told him, I described in detail the process of using an electric saw to saw open the chest bone, scaring him badly.

More than ten years ago, I told him there was minimally invasive Shou Bing, just three holes and it could be done.

Ten years ago, I told him to use interventional surgery, from the neck or wrist, or... jokingly said, any artery, guidewire catheter goes down in, once the umbrella opens, the Shou Bing ends.

But that coward still didn't dare to do it.
