"Use freezing technology..." Su Yun asked at the beginning and stopped.

"I have considered it, but the patient is now pleating hemoptysis. If he doesn't master the standard, he is more likely to have problems." Fang Lin frowned.

"I think you can try it. This location freezing technology should be more suitable." Zheng Ren said softly as he looked at the film.

Fang Lin carefully pondered the difficulties of making bronchoscopes + freezing technology, which was a bit difficult.

Zheng Ren watched the film, entered the system space, and prepared to do a bronchoscope.

The principle of freezing technology is to treat the lesions based on the joule-thson effect to achieve the goals required by the doctor.

After the high-pressure gas in the cryoprobe is sprayed through the nozzle, it expands sharply in the low-pressure area. When the probe comes into contact with the tissue, it exchanges heat with the tissue, and takes away the tissue heat and freezes the tissue.

Tissue damage caused by freezing can occur at the cell level and tissue level, without causing more damage.

The difficulty of the patient's condition is that foreign objects in the bronchial tract or stones are severely adhered to the surrounding tissues, which has caused the bronchial wall to rupture and bleeding.

It is possible to 350ml of hemoptysis, which means that the bleeding blood vessels are relatively large, at least as large as the branches of the bronchial artery.

The adhesion is severe, not a ball of foreign objects with clear boundaries. To be honest, it is difficult to completely remove foreign objects in the bronchial duct to the frozen technology.

Fang Lin’s concern is whether taking out foreign objects directly and retaining lung tissue will cause more severe hemoptysis, which has never endangered the patient’s life.

I can only try it.

Zheng Ren started the surgical training with a try attitude. If it really doesn't work, he can only remove the lung lobes according to Fang Lin's opinion.

Before the operation, 10 mg of sediapam was intramuscularly 30 minutes. Zheng Ren still felt worried, so he added 50 mg of lysine and atropine O.5 mg of intramuscularly, and gave 2% lidocaine 10 ml atomized inhalation.

After the drug took effect, Zheng Ren operated a fiber bronchoscopy and inserted it into the right lung with a problematic lower right lung.

Soon, Zheng Ren saw a foreign object.

Mucosal edema and granulation hyperplasia can be seen as a foreign object at the distal end, wrapped in granulation tissue. The camera bleeds significantly after touching the foreign object, and it is accompanied by a large amount of purulent secretions overflowing.

What the hell is this? It looks like something is wrong. It looks...it seems very familiar.

Zheng Ren carefully looked at the wrapped foreign objects with a fiber bronchoscope, and suddenly thought of several case reports published in China.

It's... chili.

Eating chili peppers by mistake and sucking them into the lungs is an incredible thing, but there are still reports of intermittent over the years.

However, knowing what a foreign object is is useless.

Combined with the medical history and the patient's recurring attacks, foreign objects should have been several years, and granulation hyperplasia is obvious, resulting in a small mouth of the tube, making it difficult to remove the foreign objects completely inside. In addition, foreign objects are adhesions to the surroundings, and bleeding after touching the mirror. It is quite difficult to remove them completely.

Zheng Ren did not hesitate and first cleared the secretions and necrotics on the surface of the lesion so that the cryoprobe could fully contact the lesion.

Then, the sterile cryoprobe is inserted through the biopsy hole, and the metal end of the cryoprobe is placed in the center of the lesion. The probe is more than 5 mm away from the distal end of the bronchoscope. The tip of the probe can be used to act vertically or tangently on the tissue, or directly act inside the lesion to produce the maximum freezing effect.

Press the pedal to start the probe. After about 15-20 seconds, an ice hockey will form at the top of the probe. The tissue will turn white and freeze. After loosening the switch, it will melt naturally.

1-3 freezing-ablative cycles, each cycle lasts for 3-4 minutes in the same or adjacent areas. Larger lesions can have more freezing points until the visible part is completely frozen.

After several failures, Zheng Ren summarized his experience.

The freezing time is about 18 seconds, and it takes 4 freezing-ablative cycles, and the duration of each cycle is 3 minutes and 20 seconds.

Finally, when there was a small amount of bleeding, the entire foreign object was clamped out by Zheng Ren with foreign object clamps.

The peppers are already sucking, exuding an unacceptable weird smell.

Because of the severe corrosion of the bronchial wall, Zheng Ren removed another bronchial stent and completed the operation.

Looking at the prompt that the operation is completed by 99%, Zheng Ren breathed a sigh of relief.

He was curious about what had changed in the trachea of ​​the pepper.

Holding the hemostatic forceps, Zheng Ren began to open the mechanized layer wrapped outside the pepper. But as soon as he opened it, the smell emitted by the rotten pepper rushed into Zheng Ren's nasal cavity, composed of support cells, olfactory cells and basal cells.

Through the olfactory nervous system and the trigeminal nervous system, it enters the olfactory bulb part of the terminal brain.

After a moment of trance, Zheng Ren almost fainted in the system operating room.

This smell... No wonder Quan Xiaocao doesn't eat anything. It's strange that he can eat it every day.

And it is not only smelly, but also toxic gas. If it weren't for the physical fitness being enhanced in the system space, Zheng Ren would probably faint in the operating room.

Even if people can survive, countless surgical training time will be "wasted", and Zheng Ren will even have the desire to die.

Zheng Ren came out of the system operating room and ended his surgical training. If he fainted in the system operating room, so much surgical training time would be spent in vain, and Zheng Ren was heartbroken.

"Boss, are you good at freezing technology? I think you can try it. Although it is very difficult, I am ready to cut the lung lobes anyway. Why..."

"You can try it. In the hybrid operating room, first use a fibronectomy to retrieve foreign objects with a frozen technique. If it is successful, the next bronchial rack will block the bleeding point."

Su Yun felt confident when he heard his boss say this.

"Fang Lin, who are you second-tier professors today?" he asked.

The hospitalization is responsible for the emergency department. Of course, the second line of surgery that is dangerous and may not be able to be taken.

"Teacher Zhu second-tier, but he has a lot of surgery today and hasn't finished it yet." Fang Lin said.

"Go to communicate with the patient's family and then look for the second line to see the situation." Su Yun said.

Fang Lin didn't hesitate. Since Boss Zheng said it was OK, just take him to take a look. As for Teacher Zhu, who is on the second line, if he wants to try it, he won't stop him.

There are eight laparoscopic surgery a day, and it is said that three laparoscopic radical esophageal cancer surgery will be performed in the afternoon. He has no time to deal with a foreign body in the bronchial line.

"Boss Zheng, Brother Yun, wait for me." Fang Lin said swaying with a big red stethoscope.

"Well, we'll go back to the ward to wait for you." Zheng Ren said, "I'm ready to call Su Yun and we'll go up."

After saying that, Zheng Ren thought for a while and said to Su Yun: "What class Lao He? Let's get a table together. If there is heavy bleeding, emergency intubation is required."

When Fang Lin thought of heavy bleeding and emergency intubation, he started to have a headache.

Once this surgery is done in an emergency room, the risk will suddenly increase.
