Chapter 2497 Metal Texture

In the singing of Good Luck, Lao He held a mask and put it over Xiaoshi's mouth and nose.

Between breaths, the little stone fell into a deep sleep under the effect of the medicine.

"Boss Zheng, this kid is quite sensible." Lao He looked at the sleeping little stone and said.

"Yeah." Zheng Ren nodded, "Anesthetized, ready to position yourself."

Xiao Shitou's surgery position has been rehearsed many times. Zheng Ren will perform neck tumor resection surgery with interventional cooperation, which is different from ordinary surgery.

Gao Shaojie and Lin Yuan started to get busy, and Zheng Ren didn't call anyone else. He and Su Yun prepared to complete the whole surgery.

For him at the peak level, the existence of an assistant is meaningful, but he needs an assistant at Su Yun's level. Moreover, angiography and local application of contrast agent must be performed through the radial artery, and there is really no room for more people on the operating table.

Lao He was busy, intubating, adjusting the value of the ventilator, and administering medicine.

Xie Yi was counting the equipment with the itinerant nurse. At the beginning, the equipment nurse and the itinerant nurse were very resistant to being disturbed by others. Once you forget to count, you have to start all over again.

When I met a hot-tempered itinerant nurse, I would go berserk, pointing my nose and cursing.

Zheng Ren stood quietly in front of the film reader, watching the film for the last time with his arms folded.

After 12'22", Su Yun's voice came: "Boss, don't meet each other, and come to the stage with your hands. "

"Yeah." Zheng Ren nodded, then turned to brush his hands.

After the body position was set, Zheng Ren went to put on the lead suit and brush his hands, and when he came back, he stood firmly by the side, and did not stand by the operating table in the first place.

The air-tight lead door was closed, Gao Shaojie had already completed the puncture, and Lin Yuan started to step on the line with the cooperation of his assistant to perform super selection.

What he's going to do is inject indocyanine green locally into the blood vessels.

In 2009, Ishizawa, an oriental scholar, discovered that patients with liver tumors were injected intravenously with indocyanine green before surgery. During the operation, near-infrared imaging technology could be used to detect the fluorescence of the tumor tissue, which made it possible to visualize the tumor lesions in real time during the operation.

Indocyanine green was originally used in the diagnostic treatment of liver segmentation and other liver diseases.

Over time, surgeons have discovered the extent of tumor tissue that can be examined with infrared imaging.

So in the next few years, special endoscopic surgical treatment methods for gastric cancer, esophageal cancer and other cancers marked with indocyanine green were rapidly launched in clinic.

It is only because the technology of molecularly targeted fluoroscopy has not been promoted by competent people, and many clinicians feel that it is not necessary at all. In addition, it is necessary to change surgical habits and apply new instruments, so the advancement of this technology is very slow.

Indocyanine green, as the only NIR fluorescence approved for clinical use, has achieved initial results in applications such as liver cancer imaging and sentinel lymph node imaging. However, since indocyanine green itself does not have tumor-targeting properties, since then, targeted fluorescent molecular probes have entered people's field of vision.

Zheng Ren used this technology this time to accurately locate the tumor.

And he goes further than anyone else!

The normal molecular-targeted fluoroscopic technique requires peripheral intravenous administration before surgery, and the drug is distributed to the tumor tissue along with the blood circulation.

With the help of infrared fluorescence camera, the part with tumor tissue is presented on the screen, so that the surgeon can have a deeper understanding of the patient's condition.

However, Xiaoshi’s condition is more serious and his body is weaker. There is no point in administering systemic drugs through peripheral veins. No matter what, it will increase the burden on the liver.

So Zheng Ren directly decided to intervene in the external carotid artery to directly act on the tumor in the operation area to make it visible.

In doing so, fewer doses of the drug are given. And for some insensitive developing positions, drug administration and contrast examination can be repeated. Compared with intravenous administration, the accuracy and repeatability are much higher.

One operation spans three surgical departments, and interventional methods are required to participate, which can only be done by Boss Zheng who leads the interventional treatment team.

He didn't need to coordinate the relationship between departments, he only needed one sentence to pull Gao Shaojie to the stage.

The interventional operation started, Zheng Ren squinted his eyes and looked at the screen.

Opposite the operator is the intervening screen, while another infrared-developed screen hangs above the small stone's leg side.

In this way, both Zheng Ren and Su Yun, who is his assistant, can clearly see the tumor tissue under fluorescence imaging.

There are almost all kinds of machines around the entire operating table, such as ventilators, monitors, micropumps, interventional imaging screens, and fluorescent infrared imaging screens.

Zheng Ren and Su Yun wore microscopes on their heads.

In addition to the operating box given to Zheng Ren by Dr. Charles placed in front of Xie Yiren, everything made this operation look like an all-metal texture.

This is no longer the operating room of 912, but rather an operating room from the future.

Zheng Ren silently watched Gao Shaojie do the radiography and give a small amount of contrast agent with a high-pressure syringe.

This "simple" operation did not require Zheng Ren to do it himself.

After Gao Shaojie finished the operation, Zheng Ren walked to the operating table.

He first adjusted the angle of the camera and the shadowless lamp that were covered with a layer of sterile plastic film, then took a deep breath and gently stretched out his hand.

The handle of the lancet immediately slapped Zheng Ren's palm.

The huge "S"-shaped incision appears in the surgical area with the winding of the lancet, and the curve is flawless. After incision, Zheng Ren slapped the lancet on the side of Xiaoshi's leg. Stretching out his hand, clapping the sterile gauze and hemostatic forceps in the palm of his hand.

Su Yun held an electric burner and hemostatic forceps in his hand to assist Zheng Ren in stopping the bleeding.

After incision of the skin, the images presented by the infrared camera on the screen will show green tumor tissue and slightly discolored sentinel lymph nodes under infrared light.

Looking at Boss Zheng surrounded by countless machines, Lao He felt a sense of bewilderment in his heart.

This kind of scene is too black technology, and it is not the usual scene of the surgeon who Lao He is familiar with.

It's a little strange, but there is a little bit of familiarity in the strangeness.

The bleeding after cutting the skin edge, the hemostatic forceps and electric burn in Su Yun's hand, the blunt scissors and hemostatic gauze in Boss Zheng's hand.

All of these have diluted the cold mechanical feeling a little, making it look a little more real.

Lao He took a deep breath and puffed his cheeks, so as not to be overwhelmed by this heavy metal frenzy of technology.

It is enough for me to be responsible for this part of myself, and I must not make mistakes!

He pushed his assistant aside and carefully looked around his territory - ventilator, monitor, micropump and so on.

I am just a part of the medical team, and it is enough to take good care of myself without delaying the operation of the whole machine. This is the position Lao He gave himself.

As for the central control equipment, Boss Zheng, he just needs to cooperate as much as possible. As for how to do the surgery and how the postoperative effect will be, that's what Boss Zheng should consider.
