"Xiao Xiao, what are you thinking about?"

Liu Tie was suddenly stunned and became anxious.

If his wife knew about this, he would have to go back and kneel on the washboard.

Puff.

Seeing Liu Tie's nervous look, Li Wenxia laughed.

"Director Xiao, don't tease Brother Liu. He is really afraid of his wife. Every time I call him to talk about business, he is very nervous and seems to be afraid to say anything."

"Oh? There is also this matter."

Xiao Chenguang looked at Liu Tie happily.

Now Liu Tie's old face can't be saved.

"This fully illustrates my love for my wife. You unmarried people will definitely not understand me."

"Yes, yes, we don't understand."

Seeing Liu Tie's refusal to admit it, everyone laughed.

"You haven't said it yet. What did you want to tell me just now?"

Just when Xiao Chenguang asked this, his pager suddenly rang.

This instantly broke the originally relaxed and happy atmosphere.

"Emergency consultation on the gastrointestinal surgery table?"

When Xiao Chenguang saw the information on the BP machine, he was obviously stunned.

Emergency consultation on the table is not common. Generally, the chief surgeon encounters uncontrollable problems and then asks for emergency consultation.

To put it simply, it is to save the table.

"Gastrointestinal surgery? When we came out just now, they were indeed performing surgery. It seems that the patient had intestinal rupture. The operation should not be difficult. At this point, they should prepare for the backstage."

Liu Tie, who was sitting next to Xiao Chenguang, happened to see the information above.

He looked puzzled. After all, he happened to help in the next room before leaving get off work, so he knew about this situation.

"You guys eat, I'll go check the situation first."

At this time, Xiao Chenguang had almost finished eating. He put down his chopsticks, drank the mung bean soup next to him, and prepared to go out.

"Boss, where am I."

At this moment, Lin Gaoyang also put down his bowl and chopsticks and looked at Xiao Chenguang.

"You don't need to go yet. Come back to the ward after dinner. If you need me, I will ask the nurse in the operating room to call you in advance."

After giving instructions, Xiao Chenguang walked quickly to the eighth floor of the inpatient department.

After arriving at the operating room, he changed into surgical gowns, asked about the operating room that needed consultation, washed his hands, opened the door, and walked in.

"Director Xiao, you are finally here. I really don't know what happened to the patient, so I asked you to come and see."

Sun Chengwu stood on the stage, sweating profusely at this moment. The azure surgical cap was already half wet, and the sweat was constantly flowing down.

If there was no nurse to help wipe the sweat, the surgical gown would probably be soaked.

"Director Sun, what's the patient's condition?"

Xiao Chenguang glanced at the monitor on the stage and found that the patient's vital signs were a little abnormal.

The heart rate was not fast, the blood pressure was normal, but the blood oxygen saturation was very low.

This was obviously not normal.

Seeing that Xiao Chenguang got straight to the point, Sun Chengwu didn't waste any words and immediately reported the patient's condition.

An elderly male had intestinal obstruction caused by eating sweet potatoes at home.

Because he delayed the operation for too long, his small intestine was perforated and he was urgently admitted to the hospital.

When Sun Chengwu was on stage, the operation went smoothly at the beginning, but just as he was about to step down, the patient's blood oxygen saturation suddenly dropped.

After a long time of anesthesia, even when the oxygen concentration of the ventilator was 100%, the patient's hypoxia did not ease.

An urgent arterial blood gas test showed that the oxygen partial pressure was only 58mmHg.

This was already very dangerous.

As the director of gastrointestinal surgery, Sun Chengwu tried his best but could not find the problem.

There was no other way, so he could only ask for help from the general surgery department by phone.

After all, compared with face, the safety of the patient is more important.

"So, the patient's oxygenation index is only 58mmHg?"

Xiao Chenguang's heart sank.

He took another look at the 100% oxygen concentration on the ventilator.

He thought that the patient was already in an extremely high-risk state in this situation.

The oxygenation index is also called the P/F ratio. The normal range should be between 400 and 500 mmHg. It is an indicator used to evaluate the oxygenation of patients under ventilator support.

The patient is only 58 now, which means that his lung function is very poor and has reached the point of respiratory failure, requiring emergency treatment.

"Did you check his blood gas when you went on stage?"

"Yes, the arterial blood gas is normal. When the oxygen concentration of the ventilator is 50%, the oxygen partial pressure is above 300 mmHg."

Calculated in this way, the patient's oxygenation index is at least above 600, indicating that the lung function is normal.

"Is the patient's blood oxygen saturation decreasing linearly or slowly?"

"It dropped suddenly, very fast."

Xiao Chenguang asked several questions in a row. After getting the response of anesthesia, the relevant diagnosis immediately emerged in his mind..

Pulmonary embolism.

Or even more critical air embolism.

At this moment, a piercing alarm suddenly erupted in the operating room.

On the monitor, the blood pressure, which was normal just now, also dropped precipitously.

The speed and severity of the change in the condition were obviously beyond everyone's expectations.

"What happened? How could it become like this?"

Even Sun Chengwu, who had performed surgery for so many years, was frightened and a little overwhelmed.

He didn't understand why a surgery that was usually considered insignificant suddenly turned into this situation.

"Did you use hydrogen peroxide to disinfect the mucous membrane?"

Xiao Chenguang suddenly saw a small white bottle that had been unpacked and opened in the corner.

The label on it clearly said hydrogen peroxide.

Hydrogen peroxide, also known as hydrogen peroxide, is used to disinfect the skin surface and traumatic tissue after trauma.

It is most commonly used for debridement and suturing.

It will decompose into water and oxygen when it encounters impurities to remove the anaerobic environment of the wound, prevent the colonization of tetanus bacilli, and disinfect bacteria, fungi, and spores.

In the early years, hydrogen peroxide was also used to disinfect surgical wounds, but due to its certain corrosiveness, it was gradually replaced by solutions with better disinfection effects after the millennium.

In the operating room, facing Xiao Chenguang's sudden inquiry, Sun Chengwu was obviously stunned.

Hydrogen peroxide disinfects necrotic tissues, isn't this a routine operation?

Why did Xiao Chenguang ask this?

But he still quickly replied: "Yes, when performing intestinal anastomosis just now, two bottles of hydrogen peroxide were used."

After getting the answer, Xiao Chenguang immediately came to the bedside, not caring about the sterile sheet on the patient.

He directly opened it, took the stethoscope next to him, and placed it on the patient's chest area.

Immediately, a continuous and loud bubbling sound and a rumbling sound of being crushed by wheels came from the stethoscope.

"It's air embolism."

When Xiao Chenguang told everyone present the diagnosis, everyone showed an extremely horrified expression on their faces.

Air embolism? !

Wouldn't that mean the patient is doomed?

When Sun Chengwu, the surgeon in charge, heard this conclusion, his face turned pale instantly.

A chill ran directly from his spine to the back of his head.

He was even more panic-stricken, as if he had encountered the god of death who was waving his sickle and preparing to harvest death.
