Zhou Congwen didn't explain too much.

After pressurizing the mask for 15 minutes, the blood oxygen saturation was maintained at 95%, and the skin ecchymosis was reduced.

Seeing the skin's ecchymns fade gradually, Li Qinghua and Liu Wei's hearts were relieved, but before they could reach the end, they were still hanging in the air.

As for why...

They looked at Zhou Congwen at the same time.

Let’s talk about it later. Since Zhou Congwen has said that, don’t waste it on the operating table. It’s meaningless.

After reducing the oxygen flow and observing for a few more minutes, the patient's blood oxygen saturation was still stable, so he sent the patient back to the small monitoring room of the thoracic surgery department.

Just like when rescuing patients, Li Qinghua ran to ask for an elevator, and the road was unobstructed. The patient was sober, could communicate and speak with a clear and clear voice.

He was sent to the small guardian room, but no one left, especially Liu Wei, who called Corey and said that he would go back a while later and stayed.

He was very worried about something that happened to the patient and was filled with worries between his eyebrows.

After observing for thirty minutes, the patient's skin on both lower limbs gradually disappeared. Zhou Congwen then smiled and said, "Go to the office."

Li Qinghua nodded and several people came to the office.

"Congwen, what's going on? I'm scared to death." Li Qinghua entered the office, took off his calm mask in the ward, revealing an anxious expression.

The same was true for Liu Wei. He sat muffled on the bed in the director's office, staring at Zhou Congwen, waiting for him to tell what happened.

Zhou Congwen is not very old, but several clean rescues left a deep impression on everyone. If you have any problems that cannot be solved, you will directly look for Zhou Congwen. This is a skill and has nothing to do with age.

"Reticular ecchymosis is not common. It is a skin vasomotor disorder caused by a variety of reasons, resulting in spasm of arterioles and anterior capillary sphincters, dilation of capillaries and veins, and blood stasis."

"We can encounter an example, which is also considered..." Zhou Congwen paused helplessly when he said this.

I don't know if it's a good thing or a bad thing.

In the best view, Li Qinghua and Liu Wei have seen him, so they can be patient and wait for the patient to be in a stable state.

If I were not here, I was really afraid that they would give the medicine in a mess.

"Xiao Zhou, how did you come from?" Liu Wei asked in a daze.

"Autoimmune diseases such as systemic lupus erythematosus, hematologic hypersensitivity diseases such as erethroidism, neurological diseases, catecholamines, and adamantine drugs can also cause skin ecchymosis."

“…”

Liu Wei was helpless, and Zhou Congwen said this as if he hadn't.

"I will summarize from the beginning that the patient under general anesthesia today under general anesthesia and thoracoscopic pleural fixation, and the anesthesia surgery was smooth.

However, after the tube is extubated, the blood oxygen saturation decreases, blood pressure increases, and heart rate increases; then the symptoms of reticular ecchymosis on the skin of both lower limbs appear."

"There are several possibilities. The first is that extubation stimulation causes bronchospasm, reduced lung ventilation, and poor lung function in the patient, which causes hypoxemia and hypoxic reflexive excitatory sympathetic nerves."

"The second type is not considered for the time being because the operation time is long, the operating room temperature is low, and the temperature is not protected during the operation, which leads to the patient's body temperature being low after the operation. The low temperature will cause skin vasospasm and sympathetic nerve excitation.

Our surgery lasts only forty minutes, which is impossible.”

"The last possibility is sputum suction, and the stimulation of the tube can also cause sympathetic nerve excitation."

Liu Wei wanted to cry without tears.

Is it wrong to operate carefully and suck phlegm well when extubating the tube?

Zhou Congwen looked at Liu Wei's expression and smiled, "Old Liu, it's okay, I just talked about a possibility. You did a good job, especially good."

Liu Wei was a little depressed and grinned hard, but he didn't laugh, which was a bit like Li Ran.

"Sympathetic nerve excitation increases the heart rate of the patient, increases blood pressure, and increases the heart rate, which leads to a shortening of the right heart diastolic period and stagnation of the systemic circulation in the veins.

At the same time, the sympathetic nerve is highly excited, and the large release of catecholamines causes strong contraction of the skin blood vessels and vasospasm, leading to skin microcirculation disorders and blood stasis, resulting in reticular ecchymosis in the left chest wall and both lower limbs.”

"But similar situations are rare, don't care." Zhou Congwen sighed.

Don't care, it's okay to comfort Liu Wei, but Zhou Congwen is a student led by Boss Huang, and he always has a bad idea in his mind.

Even if you are as strong as your own boss, you still think...

This is a historical limitation, and Zhou Congwen comforted himself.

Perhaps after decades and hundreds of years, many of the troubles that doctors face now have disappeared. However, at that time, doctors knew more and had more troubles.

"Is there any way?" Liu Wei asked a stupid sentence.

Zhou Congwen said with a smile, "It is said that the application of dexmedetomidine intraoperatively can reduce complications related to extubation."

"Is that true..." Liu Wei was a little confused.

Zhou Congwen patted Liu Wei on the shoulder and repeatedly comforted him, "It's okay, Lao Liu, you've done a good job."

The words of comfort are just comforting and have no essential effect, and Liu Wei is still a little depressed.

But he is an old anesthesiologist after all, and has a strong ability to self-regulate.

Soon, Liu Wei smiled and said, "If we don't say that we can't do it. Men are afraid of choosing the wrong career, and women are afraid of marrying the wrong man."

"Hahaha." Zhou Congwen laughed, it was indeed the case.

"No matter how much you learn, it's useless. The basic subject is just like that. Before it has developed, how can we avoid all complications in clinical practice?"

"Well, you're right."

"Let's take a step by step. My timid operation cannot avoid accidents. By the way, a patient at the People's Hospital was awake during the operation a while ago?" Liu Wei began to gossip.

The so-called soberness in the art is called knowledge in the art.

This is an extremely terrifying, even cruel situation. Zhou Congwen sighed deeply when he heard Liu Wei say this.

"Do you know about it during the operation? What surgery?" Li Qinghua asked.

"The neck clearance surgery for thyroid cancer." Liu Wei also sighed, "The People's Hospital was also confused. The patient did not step down after the operation. He woke up and kept crying. He was frightened and was in a bad state."

"The patient will not react to the outside world, but in fact his consciousness is clear. The surgery is one after another, like Lingchi... It's really terrible." Li Qinghua put himself in for a moment and shivered involuntarily.

"If surgery is performed in this state, patients with surgery will clearly feel it every time they are cut, ligated, and electric fever. Alas, there are no relevant statistics in our country. The data in the United States is known in more than 60,000 cases a year."

“!!!”

"so much!"

Li Qinghua and Liu Wei were both stunned.

There are more than 60,000 cases, how could there be so many? In their opinion, it is a rare situation to know in art. We have never encountered a case in both Liu Wei and Li Qinghua in so many years.
