Seeing that the patient is now awake, his blood oxygen saturation has reached about 95, and his vital signs are quite stable.

Lin Yi then explained to Wang Qiaoya and the others how the patient was in a coma.

"First of all, the patient's head does not have any trauma, and the pupils are so large that the reflexes are normal, so the coma caused by head trauma is basically ruled out."

"Looking at his right side of his chest again, there is a crepitus to the touch, which is a sign of subcutaneous emphysema, indicating that this patient has a rib fracture on his right side."

"And the percussion is a tympanum, and there are no breath sounds on auscultation, what does this mean? This indicates that the patient has a pneumothorax. ”

"And his sudden coma was caused by a tension pneumothorax!"

Speaking of this, Lin Yi glanced at Wang Qiaoya and Chen Qiang.

"Tension pneumothorax, you know?"

Chen Qiang lowered his head and pondered for a moment, then shook his head and said:

"I don't know."

Wang Qiaoya blinked and said:

"Tension pneumothorax, also known as hyperbaric pneumothorax."

"Commonly seen in rupture of larger lung bubbles, or in larger and deeper lung lacerations or bronchial rupture."

"The tear communicates with the pleural cavity and forms a flap, so that air can enter the pleural space through the tear when inhaled."

"The flap closes during exhalation, preventing air from the cavity from returning to the airway and expelling."

In this way, the accumulation of air in the pleural cavity continues to increase, and the pressure continues to rise, compressing the injured lung and causing it to gradually collapse.

"And push the mediastinum to the unaffected side, squeezing the unaffected lung, creating severe impairments of respiratory and circulatory function."

"Sometimes high-pressure pneumoplea in the pleural cavity is squeezed into the mediastinum and spreads to the subcutaneous tissues, forming subcutaneous emphysema in the neck, face, chest, etc."

Lin Yi couldn't help but nod slightly, it seemed that Wang Qiaoya's theoretical knowledge was indeed in place.

But then, he couldn't help but say to Wang Qiaoya:

"Although you have memorized the definition of tension pneumothorax quite clearly, you must understand it and really use it."

"When you encounter this kind of patient, but you don't know how to deal with it, otherwise no matter how good the definition is, what's the use?"

Wang Qiaoya couldn't help nodding in agreement.

Indeed, her current situation is that the theory is in place, but she has no practical experience.

When you really meet a patient, even if you know the knowledge of the disease, you can't judge it, and it's still useless.

However, she is only a regular trainee, and she does have little clinical experience, which is also helpless.

Therefore, she will follow Lin Yi more in the future and strengthen practical learning!

These emergency patients are valuable learning experiences for her.

The patient had just improved when the ambulance brought in another patient with an open comminuted fracture of the left thigh.

His left thigh was a blur of flesh and blood, and his lower left limb had bent at an eerie angle.

"This patient injured the femoral artery, and now the bleeding is very serious, come and rescue someone."

The emergency doctor, who was pushing the patient, shouted.

Now every doctor has patients.

Lin Yi happened to have a little free, so he asked Wang Qiaoya and Chen Qiang to look at the patient with tension pneumothorax just now.

And he himself went to see patients with massive bleeding.

The patient's injuries were severe, but he was in no pain, apparently in shock, and the bleeding had to be stopped as soon as possible, followed by a blood transfusion.

Lin Yi gently picked up a cotton pad pressed on the wound and examined the wound.

A stream of bloody arrows shot out immediately.

Lin Yi hurriedly suppressed it again.

"He injured his femoral artery and had to be operated on as soon as possible!"

The emergency doctor said quickly.

In this patient's case, the entire left thigh was comminuted with a fracture.

Moreover, the damage to the skin, muscles, blood vessels and nerves is particularly severe.

His femoral artery was directly ruptured.

If only the general strapping hemostasis method is used, it is impossible to stop the bleeding of the femoral artery.

Either go to the operating table immediately and give him surgery.

However, in the current situation, it is not realistic to go to the operating table for surgery immediately.

Because there are not enough people, everyone is busy.

Even now, not a single medical worker is idle.

But there is still a steady stream of ambulances, bringing patients here.

How can I get people out and go to the operating table for surgery?

Generally, it can only be handled simply temporarily.

When it comes to major surgery that requires more than two medical staff, it is only possible to do it until all the trauma patients have been completely stabilized.

I can't do it right now.

wanted to stop the bleeding of this trauma patient with a ruptured femoral artery as soon as possible, Lin Yi thought of a way.

He's going to do REBOA for patients!

REBOA stands for Resuscitive Aortic Balloon Occlusion.

At present, this is the only way to stop femoral artery bleeding.

"I need a urinary catheter, a 14-gauge needle, an artery occlusion balloon. 20 ml saline, a little faster. ”

After thinking of a countermeasure, Lin Yi immediately told the nurse what he needed.

The nurse on the side hurriedly took all these things.

Subsequently, after the patient's left thigh was disinfected, Lin Yi prepared to perform femoral artery puncture.

"What are you doing here?"

The emergency doctor who helped was pressing on the patient's wound.

He looked at Lin Yi's operation and couldn't help but ask suspiciously.

"I'm going to give him a resuscitation aortic balloon occlusion. Only then will he be able to stop the bleeding completely. ”

"But now there is nothing ready-made, I can only make a simple one."

After Lin Yi finished talking to him, he stopped talking nonsense, and directly pierced the puncture needle into the common femoral artery at once.

It stands to reason that resuscitation aortic balloon occlusion needs to be guided by ultrasound in order to be done accurately.

But now that the situation is urgent, it is impossible to push the patient to do color ultrasound.

However, with Lin Yi's expert-level surgical ability, there is no need for color ultrasound guidance.

Because he knows the distribution of blood vessels in the human body well, and can find the right position through his senses!

Lin Yi inserted the puncture needle into the common femoral artery without the slightest difficulty, and then the catheter sheath was implanted.

A catheter with a balloon is placed all the way to the abdominal aorta, and the balloon is inflated to hold it in place.

It's that simple!

Lin Yi then said, "You can let go." ”

The emergency doctor and the nurse on the side suddenly looked at Lin Yi in disbelief.

They kept pressing the patient's left thigh tightly, not daring to slack off.

It wasn't until they heard Lin Yi say that it was okay that they let go of their hands suspiciously.

Looking at the patient's femoral artery rupture again, there was no blood flowing out at this time.

"Success, amazing, Dr. Lin!"

The nurse exclaimed with heartfelt admiration.

The emergency doctor also cast a look of adoration at Lin Yi.

He was in the ambulance and pressed the patient all the way, and he kept bleeding.

As a result, Lin Yi completely stopped the bleeding in a few minutes, and he was a master at a glance.

Song Borui was rescuing a patient with a head injury in the bed next to him.

But he witnessed Lin Yi perform resuscitation aortic balloon occlusion throughout the whole process.

Immediately amazed!

"Brother Shen!"

"Hmm!"

Shen Changqing walked on the road, and when he met someone he knew well, he would say hello to each other or nod his head.

But it doesn't matter who it is.

There was no superfluous expression on everyone's face, as if they were very indifferent to everything.

on this.

Shen Changqing is used to it.

Because this is the Demon Suppression Division, it is an institution that maintains the stability of Great Qin, and its main responsibility is to kill demons and monsters, and of course there are some other side jobs.

Arguably.

In the Demon Suppression Division, everyone has a lot of blood on their hands.

When a person is accustomed to seeing life and death, then he will become indifferent to many things.

When he first came to this world, Shen Changqing was a little uncomfortable, but over time he got used to it.

The Demon Suppression Division is huge.

The people who can stay in the Demon Suppression Division are all powerful masters, or people who have the potential to become masters.

Shen Changqing belongs to the latter.

Among them, the Demon Suppression Division is divided into two professions, one is the town guard and the other is the demon exterminator.

Anyone who enters the Demon Suppression Division starts with the lowest level of demon slayer.

Then step by step, he is expected to become a town guard.

Shen Changqing's predecessor was a trainee demon slayer in the Demon Suppression Division, and he was also the lowest level of the demon slayer envoys.

Have memories of the predecessor.

He is also very familiar with the environment of the Demon Suppression Division.

It didn't take long for Shen Changqing to stop in front of an attic.

Unlike other places full of slaughter, the attic here seems to stand out from the crowd, and in the bloody Demon Suppression Division, it presents a different tranquility.

At this time, the attic door is open, and there are occasional people entering and exiting.

Shen Changqing only hesitated for a moment, and then stepped in.

Access to the attic.

The environment has changed in vain.

A burst of ink fragrance mixed with the faint smell of blood came to his face, making his brow furrow instinctively, but quickly stretched.

The smell of blood on everyone's body in the Demon Suppression Division is almost impossible to clean.
