“Using freezing technology …” Su Yun started and then stopped.

“I’ve thought about it, but the patient is suffering from globules. If we don’t control the freezing scale well, there’s a higher possibility that there will be problems. ” Fang Lin said with a frown.

“I think we can give it a try. This cryo-chamber.” Zheng Ren looked at the film and said softly.

Fang Lin carefully pondered over the difficulties of performing a tracheostomy and cryonics dormancy. It was a little difficult.

Zheng Ren looked at the scan and entered the system space to get ready for a tracheostomy tube.

The principle of cryonics technology was to treat lesions based on the squirrel effect to achieve the doctor’s goal.

The high-pressure gas in the cryoprobe, after being sprayed out through the nozzle, would expand rapidly in the low-pressure area, so that when the probe touched the tissue, it would carry out a heat exchange with the tissue, taking away the heat of the tissue and freezing it.

On the other hand, tissue damage caused by freezing could occur at the cell and tissue level, and it would not cause any more damage.

The difficulty of the patient’s condition was that there was a foreign body in the bronchi, or that the stone had serious adhesion with the surrounding tissue, which had already caused the bronchi wall to rupture and bleed.

To be able to bleed 350ml meant that the blood vessel that was bleeding was relatively large, at least a blood vessel like a slightly larger bronchi artery branch.

Due to the severe adhesion, it was not a foreign object with a clear boundary. To be honest, it was difficult to completely remove the foreign object in the trachea with freezing technology.

Fang Lin’s concern was whether removing the foreign object directly and preserving the lung tissue would cause an even more intense hemorrhage. He had never endangered the patient’s life before.

He could only try.

Zheng Ren began his surgical training with the intention of giving it a try. If it really did not work, he could only follow Fang Lin’s suggestion and remove the lobular lobe.

10mg of westpan was injected before the operation. Zheng Ren still felt uneasy. He added 50mg of dullaine and 0.5mg of atropine through an intravenous injection, then gave 10ml of 2% lidocaine through an intravenous infusion.

After the medicine took effect, Zheng Ren inserted a firbotomy tube into the right lung and entered the problematic lower right lung.

Soon, Zheng Ren saw the foreign object.

There was mucous edema and granulosis. A foreign object could be seen at the far end. It was wrapped in granulosis. When the camera touched the foreign object, the bleeding was obvious, accompanied by a large amount of puss secretion.

What the hell was this? There seemed to be a problem. His appearance … Seemed very familiar.

Zheng Ren carefully looked at the foreign object wrapped in the package with a firbotomy tube. He suddenly thought of a few case reports published in China.

It was … Chili.

It might sound unbelievable that chili was accidentally inhaled into the lungs, but there had been intermittent reports of this over the years.

However, it was useless to know what the foreign object was.

Combined with the patient’s medical history and the patient’s repeated episodes, the foreign body should have been there for a few years. The granulations were obvious, causing the mouth to be small, and it was difficult to remove the foreign body completely. In addition, the foreign object was stuck to the surrounding, and the mirror would bleed after touching it. It was quite difficult to remove it completely.

Zheng Ren did not hesitate. He first removed the secretion and necrotites on the surface of the lesion so that the cold probe could fully come into contact with the lesion.

Then, the cryoprobe of the lesion was inserted through the biopsy hole. The metal end of the cryoprobe was placed in a sterile Center. The probe was more than 5 mm away from the end of the tracheostomy tube. The tip of the probe could be used vertically or tangent to the tissue, or directly to the inside of the lesion to produce the greatest freezing effect.

He stepped on the pedal to start the probe. After about 15- 20 seconds, an ice ball formed at the top of the probe. The tissue turned white and froze. After he released the switch, it melted naturally.

1-3 Each cycle would last for three to four minutes in the same or neighboring area. Larger lesions could have more freezing points until the visible part was completely frozen.

After failing a few times, Zheng Ren came to a conclusion.

The freezing time was about 18 seconds, and it had to go through four cycles of melting frozen bones. Each cycle lasted for 3 minutes and 20 seconds.

In the end, Zheng Ren used the forceps to remove the foreign object with a small amount of bleeding.

The chili had already rotted and was emitting a strange smell that was unacceptable.

Due to the serious corrosion of the bronchi wall, Zheng Ren had to put in another bronchi stent before the surgery was completed.

Zheng Ren heaved a long sigh of relief when he saw the notification that the surgery was 99% completed.

He was very curious about what had happened to the chili in the trachea.

With the hemostatic forceps in hand, Zheng Ren began to open the mechanical layer wrapped around the chili. However, as soon as he opened it, the smell of the rotten chili rushed into the sniffing epidermis of Zheng Ren’s nasal cavity, which was composed of support cells, olfactory cells, and somatic cells.

Through the olfactory nerve system and the nasal Trident nerve system, it entered the olfactory sphere of the telencephalon.

Zheng Ren was in a daze for a moment, and he almost fainted in the system operating theater.

This smell … No wonder Quan xiaocao didn’t eat anything. It would be a wonder if she could eat anything after smelling this smell every day.

Not only did it smell, but it was also poisonous. If his physical fitness had not been enhanced in the system space, Zheng Ren would have fainted in the operating room.

At that time, even if he survived, countless surgery training time would be “wasted”, and Zheng Ren might even want to die.

Zheng Ren came out of the system operating room and ended his surgery training. After coming out, Zheng Ren still had a lingering fear of the smell.

“Boss, can you do the freezing technology? I think we can give it a try. Although it’s difficult, we’re already preparing to cut the lobular tissue, why …”

“We can give it a try. In the hybrid operating theater, we can first use the freezing technique to remove the foreign object with a firbotic endoscope. If it’s a success, we’ll have to block the bleeding point with the next trachea. “

Hearing her boss say that, Su Yun felt more confident.

“Fang Lin, who’s the B-list professor today?” He asked.

Chief residents were in charge of the emergency department, so of course, second-string doctors were needed for dangerous surgeries that might not be taken down.

“Teacher Zhu is a second-string doctor, but he has a lot of surgeries to do today, so he hasn’t finished them yet.” Said Fang Lin.

“Go and communicate with the patient’s family, and then look for the second-string doctors to see how the situation is.” Su Yun said.

Fang Lin did not hesitate at all. Since boss Zheng had agreed to it, he would just drag him along to take a look. As for the second-tier teacher Zhu, he wouldn’t stop him if he wanted to try.

There were eight laparoscopic surgeries a day, and it was said that there would be three laparoscopic esophageal cancer radical surgery in the afternoon. How could he have the time to deal with a foreign object in the trachea?

“Boss Zheng, Brother Yun, please wait for me.” Fang Lin said in an unusually coquettish manner as he swayed the big red stethoscope hanging from his neck.

“Okay, we’ll wait for you at the ward area.” Zheng Ren said,”give Su Yun a call when you’re ready. We’ll go up.”

Zheng Ren thought for a moment and said to Su Yun,””What class is old he in? Let’s play together. If there’s massive bleeding, emergency intubation will be needed. “

Fang Lin’s head began to ache at the thought of having to perform emergency intubation due to massive bleeding.

Once this kind of surgery was performed in the emergency department, the risk would suddenly increase.

However, when he saw boss Zheng’s confident expression, Fang Lin was conflicted for 3.2 seconds. In the end, he decided to explain the situation to the patient’s family in detail. He would explain the risks during the surgery clearly and let the family members make their own choices.
