During the song of good luck, Lao He held a mask and covered the mouth and nose of the little stone.
Between breaths, the little stone fell into a deep sleep under the influence of the medicine.
"Boss Zheng, this kid is quite sensible." Lao He said while looking at the sleeping little stone.
"Yes." Zheng Ren nodded, "Anesthetize and prepare for positioning."
Xiao Shitou's surgical position has been rehearsed many times. Zheng Ren will perform neck tumor resection with interventional cooperation, which is different from ordinary surgery.
Gao Shaojie and Lin Yuan started to get busy, but Zheng Ren didn't call anyone else, and he and Su Yun were preparing to complete the entire surgical operation.
For him at the peak level, the existence of assistants is meaningful, but he needs an assistant of Su Yun's level. Moreover, angiography and local injection of contrast agent need to be done through the radial artery, and there is really no room for more people to stand on the operating table.
Lao He was busy, intubating, adjusting the values of the ventilator, and administering drugs.
Xie Yi was counting the instruments with the circulating nurse. At the beginning, the instrument nurse and the circulating nurse were very resistant to being disturbed by others. Once you forget to count, you have to start over.
When encountering a hot-tempered circulating nurse, she would go berserk and point at her nose and curse.
Zheng Ren stood quietly in front of the film reader, holding his arms and watching the film for the last time.
12′22″ later, Su Yun’s voice came: “Boss, stop meeting me and get on stage. "
"Yeah." Zheng Ren nodded and turned around to wash his hands.
After the posture was set, Zheng Ren went to put on the lead clothing and brush his hands. When he came back, he stood firmly on the side instead of standing next to the operating table immediately.
The airtight lead door was closed, Gao Shaojie had completed the puncture, and Lin Yuan, with the cooperation of his assistant, began to step on the line for super selection.
What he wanted to do was inject indocyanine green into local blood vessels.
In 2009, Oriental scholar Ishizawa discovered that patients with liver tumors were intravenously injected with indocyanine green before surgery. Near-infrared imaging technology could be used to detect fluorescence in tumor tissue during surgery, making it possible to visualize tumor lesions in real time during surgery.
Initially, indocyanine green was used for liver segmentation and diagnostic treatment of other liver diseases.
Over time, surgeons discovered that they could use infrared imaging to detect the extent of tumor tissue.
Therefore, in the following years, specially designed laparoscopic surgical treatments for gastric cancer, esophageal cancer and other cancers marked with indocyanine green were rapidly launched in clinical practice.
It is just because there are no qualified people to promote molecular targeted fluoroscopy technology, and many clinicians feel that it is not necessary at all. In addition, there are also changes in surgical habits and the application of new instruments, so the advancement of this technology is very slow.
As the only NIR fluorescence currently approved for clinical use, indocyanine green 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 begun to enter people's field of vision.
Zheng Ren used this technology this time to accurately locate tumors.
And he goes further than anyone else!
Normal molecular targeted fluoroscopy technology requires peripheral intravenous administration before surgery, and the drug is distributed to the tumor tissue along with blood circulation.
With the help of an infrared fluorescence camera, the part containing tumor tissue is displayed on the screen, allowing the surgeon to have a deeper understanding of the patient's condition.
However, Xiao Shitou's condition is more serious and his body is weaker. It is meaningless to administer systemic drugs through peripheral veins. It will increase the burden on the liver no matter what.
Therefore, Zheng Ren directly decided to intervene and administer the drug at the external carotid artery, directly acting on the tumor in the surgical area to visualize it.
By doing this, a smaller dose of the drug is given. Moreover, for some developing locations that are not sensitive, administration and contrast examination can be repeated. Compared with intravenous drug administration, the accuracy and repeatability are much higher.
An operation spans three surgical departments and requires interventional methods. Only Boss Zheng with the interventional treatment team can do this.
He didn't need to coordinate the communication between departments, he only needed to say a word to pull Gao Shaojie to the stage.
The interventional surgery began, and Zheng Ren squinted at the screen.
Opposite the surgeon is the interventional screen, and another infrared imaging screen is suspended above the side of Xiao Shitou's leg.
In this case, both Zheng Ren and Su Yun, as his assistant, can clearly see the fluorescently imaged tumor tissue.
There are almost all kinds of machines around the entire operating table, including ventilators, monitors, micropumps, interventional imaging screens, and fluorescent infrared imaging screens.
Zheng Ren and Su Yun wore microscopes on their heads.
Coupled with the surgical box that Dr. Charles gave to Zheng Ren placed in front of Xie Yiren, everything makes this surgery look like a full metal.
This is no longer a 912 operating room, but more like an operating room from the future.
Zheng Ren watched silently as Gao Shaojie performed angiography and used a high-pressure syringe to administer a small amount of developer.
This kind of "simple" operation does not require Zheng Ren to do it himself.
After Gao Shaojie completed the operation, Zheng Ren walked to the operating table.
He first adjusted the angle of the camera covered with a 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 slapped into Zheng Ren's hand.
The huge "S"-shaped incision appears in the surgical area as the lancet meanders, with a flawless curve. After making the incision, Zheng Ren patted the lancet on the side of Xiao Shitou's leg. He reached out and took sterile gauze and hemostatic forceps into his palm.
Su Yun held an electric cautery and hemostatic forceps in his hands to help Zheng Ren stop the bleeding.
After the skin is incised, the image displayed on the screen by the infrared camera shows green tumor tissue and slightly discolored sentinel lymph nodes under infrared light.
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 high-tech, and it is not the usual scene of a surgeon performing surgery that Lao He is familiar with.
It's a little strange, but there's also a little bit of familiarity in the strangeness.
Bleeding after incising the skin edge, the hemostatic forceps and electric cautery in Su Yun's hand, and the blunt scissors and hemostatic gauze in Boss Zheng's hand.
These all dilute the cold mechanical feeling a little, making it look slightly more real.
Lao He took a deep breath and puffed out his cheeks to prevent himself from being enveloped by this heavy metal frenzy of technology.
It is enough for you to be responsible for your own part, and you must not make any mistakes!
He pushed his assistant aside and looked carefully around his own territory—ventilator, monitor, micropump, etc.
He is just a part of the medical team. It is enough to take good care of himself and not delay the operation of the entire machine. This is the position Lao He has given himself.
As for the central control equipment, it’s Boss Zheng, so I just need to cooperate as much as possible with whatever he wants to do. As for how to perform the surgery and what the post-operative effects will be, that is what Boss Zheng should consider.
