Chapter 2499

In the song of good luck, Lao he took a mask and covered the mouth and nose of the small stone.

Between breathing, the little stone fell asleep under the action of medicine.

"Boss Zheng, the child is very sensible." Lao he looked at the sleeping stone and said.

"Yes." Zheng Ren nodded, "anesthesia, ready to put in position."

Xiaoshi's surgical position has been rehearsed many times. Zheng Ren wants to perform neck tumor resection with intervention cooperation, which is different from ordinary surgery.

Gao Shaojie and Lin Yuan began to get busy, and Zheng Ren didn't ask anyone else to prepare the whole surgery for himself and Su Yun.

For him at the peak level, the existence of an assistant is meaningful, but he needs an assistant at Su Yun's level. Moreover, we have to go through the radial artery for angiography and local developer. There is really no room for more people on the operating table.

Lao he is busy, intubation, adjusting the value of ventilator and administration.

Xie Yi people are counting the instruments lightly with the itinerant nurses. At the beginning, the instrument nurses and itinerant nurses are very resistant to other people's interference. Once you forget to count, start again.

When I met a hot tempered itinerant nurse, I would rage and point to my nose and swear.

Zheng Ren stood quietly in front of the film reader, holding his arm to watch the film for the last time.

After 12 ′ 22 ″, Su Yun's voice came: "boss, don't face each other. Brush your hands on the stage."

"Yes." Zheng Ren nodded and turned to brush his hands.

When Zheng Ren went to wear lead clothes and brush his hands, he came back and stood steadily aside. He didn't stand by the operating table at the first time.

The airtight lead door is closed, Gao Shaojie has completed the puncture, and Lin Yuan starts stepping on the line with the cooperation of an assistant to carry out superselection.

What he has to do is inject indocyanine green into local blood vessels.

In 2009, the Oriental scholar ishizawa found that indocyanine green was injected intravenously in patients with liver tumors before operation, and the fluorescence of tumor tissues could be detected by near-infrared imaging during operation, making it possible to visualize the tumor lesions in real time during operation.

Initially, indocyanine green was used for liver segmentation and diagnostic treatment of other liver diseases.

Over time, surgeons found that the range of tumor tissue could be detected by infrared imaging.

In the following years, special endoscopic indocyanine green labeled surgical treatment of gastric cancer, esophageal cancer and other cancers was rapidly carried out in clinical practice.

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

As the only NIR fluorescence approved for clinical use, indocyanine green has achieved initial results in the development of liver cancer and sentinel lymph nodes. However, indocyanine green itself does not have tumor targeting. Since then, fluorescent molecular probes with targeting began to enter people's field of vision.

Zheng Ren applied this technology to accurately locate the tumor.

And he went farther than everyone!

The normal molecular targeted fluoroscopy technology is to give drugs through peripheral vein before operation, and the drugs are distributed to tumor tissues with blood circulation.

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

However, Xiaoshi's condition is more serious and his body is weaker. Systemic administration of drugs through peripheral veins is meaningless. How can he increase the burden on the liver.

Therefore, Zheng Ren directly decided to give drugs at the external carotid artery under intervention to directly act on the tumor in the operation area and make it develop.

In doing so, the drug dose is less. Moreover, for some insensitive developing positions, repeated administration and contrast examination can be performed. The accuracy and repeatability of intravenous administration are much higher.

An operation spans three surgical departments and involves intervention. Only boss Zheng with the intervention group can do so.

He doesn't need to coordinate the contact between departments. In a word, it's enough to pull Gao Shaojie onto the stage.

At the beginning of interventional surgery, Zheng Ren squinted at the screen.

Opposite the operator is the intervention screen, while another infrared developing screen is suspended above the leg side of the small stone.

In this way, both Zheng Ren and Su Yun, as an assistant, can clearly see the fluorescent tumor tissue.

Almost all kinds of machines are scattered around the operating table, including ventilator, monitor, micro pump, interventional development screen and fluorescent infrared development screen.

Zheng Renhe and Su Yun wore a microscope on their heads.

In addition, the operating box given to Zheng Ren by Dr. Charles is placed in front of the Xie people. Everything makes the 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 angiography and give a small amount of developer with a high-pressure syringe.

This "simple" operation doesn't need Zheng Ren to do it himself.

When Gao Shaojie finished the operation, Zheng Ren went to the operating table.

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

The handle of the lancet was immediately patted in Zheng Ren's palm.

The huge "s" incision appears in the operation area with the winding of the lancet, and the curve is perfect. After cutting, Zheng Ren patted the lancet on the side of the small stone's leg. Reach out and pat sterile gauze and hemostatic forceps in the palm of your hand.

Su Yun holds an electric burn and hemostatic forceps in his hand to help Zheng Ren stop bleeding.

After cutting the skin, the image presented by the infrared camera on the screen is displayed. Under the infrared, it is green tumor tissue and slightly discolored sentinel lymph nodes.

Lao he looked at boss Zheng surrounded by countless machines and felt a sense of loss in his heart.

This kind of scene is too dark technology. It is not the scene that Lao he is familiar with.

Some strange, but strange with a little familiar.

Bleeding after cutting the skin edge, hemostatic pliers and electric burn in Su Yun's hand, blunt scissors and hemostatic gauze in boss Zheng's hand.

All these make the cold mechanical feeling diluted a little and look a little more real.

Lao he took a deep breath and puffed his cheeks so that he wouldn't be shrouded by this heavy metal frenzy of science and technology.

As long as you are responsible for your own piece, you can't make mistakes!

He turned his assistant aside and looked carefully around his territory - ventilator, monitor, micro pump and so on.

He is only a part of the medical team. It is enough to maintain himself well without delaying the operation of the whole machine. This is Lao he's positioning for himself.

As for the central control equipment, boss Zheng only needs to cooperate as much as possible. As for the operation and the postoperative effect, boss Zheng should consider it.
