medical simulator

After finishing, Yang Yifeng wiped it with sterile gauze with sterile gloves, and disinfected it roughly three times.

Taking a half step back, he stretched out his head to see how Zhou Cheng was operating.

Zhou Cheng's words were simple, and Pi Dengshan's reply was also simple, but only Yang Yifeng was having a brainstorm at the moment.

How to bluntly break through the muscle space through a small incision, reach the arteriovenous, and how to separate the arteriovenous without pinching the nerve, these are the key points.

more than a minute?

Within 5 minutes, if Zhou Cheng can complete all these, it will be.

While Yang Yifeng was still thinking about it, Zhou Cheng quickly found the positioning mark with his hands rather bluntly, and then cut a two-centimeter incision, cutting to the subcutaneous fat layer, and then followed.

Blood oozed out and quickly covered the wound.

Zhou Cheng didn't hesitate, and immediately used the vascular forceps to dig out the lower layer of fat. After a certain gap was drawn out, the vascular forceps in his hand seemed to have eyes, and the tip penetrated into it!

Then Zhou Cheng swung his tail a few more times, then shook it left and right along the direction of the incision, as if breaking the fascia between the muscle layers!

With Zhou Cheng's left hand, he inserted a blood vessel clamp again, sticking to the position of the blood vessel clamp on his right hand. It is the vascular clamp sent in later.

"Crack!" It was clamped shut with a sound.

After finishing all this, Zhou Cheng took a deep breath!

Just now, the axillary vein was clipped with assistance!

However, with another vascular clamp, there is no assistance.

There are only two pliers in a bag, not many of them.

Under the mask, he licked his lips with his tongue, and then moved slightly backwards along the closed pair of blood vessel forceps!

The veins are outside and behind the arteries.

After carefully opening the pliers head of the vascular forceps, poke it in carefully, because there is a layer of axillary sheath outside the axillary artery and axillary vein, and this layer of tough sheath must be broken.to close accurately.

This is due to the fact that Zhou Cheng is relatively comprehensive in terms of II and surgery. He is very familiar with the soft tissues and sheaths of the upper limbs, so he has a good feel.

Zhou Chengcai breathed a sigh of relief after clicking the clamp again.

Then he opened up the previous wound, tore off a small part of the gauze, and saw that the bleeding was almost gone, and the little bleeding was just residual blood, before he said, "It's ok, the bleeding has stopped temporarily." gone."

Zhou Cheng said it to Yang Yifeng, and also to Pi Dengshan.

"Take a blood pressure test! Continuous monitoring. If the blood pressure is wrong, report it immediately." Piedon Shan immediately said to a nurse in green clothes next to him.

"Okay." The female nurse didn't hesitate, and the electronic blood pressure measuring instrument was always connected to the opposite side.

At the same time, several firefighters stared at the pliers on the patient's arm and asked, "Is this all right? It may take us more than 20 minutes!"

Are you kidding me, this metal thing, if you put it in the human body, you won't be able to pull it out?

Isn't this equivalent to stabbing him directly?

Hey, it really looks like the man's arm was stabbed with two pliers.

However, a doctor is the only profession among all professions that can directly use a knife on the human body for the purpose of treatment, and is not counted as a crime of intentional injury or injury.

There is and only, in addition to this, any other profession, including forensic medicine, as long as it uses a knife on a living person, it is intentional injury!

Forensic doctors can only operate on the dead.

"If the bleeding stops, it should be fine for more than 20 minutes." Although Piedenshan is not an orthopedic surgeon, he is also a surgical surgeon. If the blood loss is limited after the artery is clamped, it is equivalent to the embolism of the blood vessel in the hand. up.

Amputation is the most, but you can gamble on the chance of limb salvage and earn money.

It can't be perfect now, it has to be like this.

"Thank you for your hard work. After the person comes out later, you must contact the stretcher in advance, and explain to the doctor who is transferring that these two forceps must not be moved until they enter the operating room!" Piedonshan participated in the scene more than once Therefore, he is also a very daring person.

"We have other tasks, so I'll trouble you. Xiao Zhou, you stay here, the others will follow me, and continue to rescue other critically ill patients." Piedonshan said hastily.

"Okay." Zhou Cheng replied, thinking that he could only take on the task of observing the patient's vital signs again.

"Okay, Professor Pi." The nurse actually replied.

Pi Dengshan had already turned his head and heard Zhou Cheng's response, but in order to save time, he said, "Yang Yifeng, bring Zhou Cheng with me. I asked Zhou Juan to stay here, not him."

Then Zhou Cheng blushed and raised his head to follow behind. At this time, Yang Yifeng turned his head and called Zhou Cheng: "Brother Zhou Cheng, let's go there together. There are still many patients here, and there are only eight medical teams on the scene now."

And Zhou Juan, the nurse behind her, smiled at Zhou Cheng and said, "Handsome guy, you can do it, we are from the same family. Professor Pi just told me to stay."

Zhou Cheng also smiled back, and then followed Yang Yifeng.

Soon, several people arrived in front of a patient. This person's upper abdomen was pierced by a steel bar from front to back. For a while, no one dared to remove it before.

Because the location of the penetration happened to be near the liver, the previous doctor saw that it was not suitable to cut off the steel bar on site.

Can only be snapped off.

If you use a chainsaw to cut it, the slight vibration of the steel bar will directly kill the person, and even the liver will be split!

There are a lot of firefighters, and several experts are here to design a rescue plan.

However, there is good news at present that the steel bar did not break the main artery, otherwise, there would be no worries about death caused by liver rupture.

At the same time, he also suffered a dislocated shoulder.

It was a dislocation visible to the naked eye. When Yang Yifeng approached, Pi Dengshan and others went to discuss how to rescue it. After Yang Yifeng took a breath of relief, he said to Zhou Cheng: "Brother Zhou Cheng, the method of dislocation like this Reset, can you do it?"

Zhou Cheng frowned: "It's meaningless to do it. His dislocation was caused by a smash. It is conservatively estimated that there will be fractures. It is better to wait for the cut and reset and not get entangled."

"Hey, didn't you get kicked out before? Why did you come in again?" Zhou Chengcai asked his curious question.

Although he died at the hands of Yang Yifeng in the simulation just now, but it was all done by himself.Moreover, Yang Yifeng is such a wonderful person, it's really not easy, he can support the task of first aid on the spot by himself.

If he had performed the operation in the hospital before he had no knots in his heart, how pleasing would it be?How extensive is the surgery?

Big finger.

Yang Yifeng said, "I was right next to me, and Professor Lei recognized me and pulled me out of the crowd."

"Professor Lei's name is Lei Zhong. He is the chief director of our Department of Orthopedics and the current dean. He is also the leader of the medical expert team. He asked me to participate in the first aid work with Professor Pi."

"Oh, your card, wear this." Yang Yifeng said, remembering the card hanging around his neck, he quickly took out one from his pocket, handed it to Zhou Cheng, and asked Zhou Cheng to hang it.

While Zhou Cheng and Yang Yifeng were chatting, the firefighters over there had already used the large scissors to 'crack (pinch off)' the steel bar, and there was a crisp, crisp sound.

At the same time, the slight shaking made the person who was penetrated let out a violent cry of pain.

"Ah~~~"

"Fuck, fuck, fuck!"

"Mom~~~~"

"Hiss~~~~" The sound of gasping for air is obviously contributing to global warming.

But no one laughed at him. Even if he was crying at this moment, no one laughed at him. This kind of pain, not to mention deep into the bone marrow, must be a real pain.

On his forehead, fine sweat kept breaking out.

After the steel bars snapped off, another big problem arose.

It's not easy to put people down. Laying it flat is equivalent to the steel bars not being shattered, and it has to bear the weight of the whole person. It is equivalent to having a sword that is constantly being pulled out inside.

Stretchers are not easy to put.

At the same time, Zhou Cheng and Yang Yifeng also noticed that the middle-aged man's leg was broken.

His big belly is bloody and bloody at the moment, black and red blood clots are scabbed on the belly, his left shoulder is dislocated and fractured, his right hand is stretching tightly to the ground, hoping to support his weight.

But the right foot was broken, and only the left foot and right hand were exerting force, like a shrimp arching its back, which was a bit miserable.

Although Pi Dengshan and others were helping to lift it, but there was a fracture, and the patient would yell when they touched it, and the pain was unbearable.As soon as Piedonshan and the others were released, the patient's affected limb was stressed, and he cried out more and more in pain.

"I'm going to die, I'm going to die!"

"It's all good if the steel bars don't crack!"

"It hurts! It hurts!"

This is not the kind of coquettishness that hurts, but the strange cry of people being numb in pain.

Pittenshan and the others immediately didn't know what to do. The traditional three-stage force method for first aid transportation was useless at this time.

Seeing this, Zhou Cheng and Yang Yifeng hurried forward to help: "Turn sideways!"

"To the right! His right arm is fine."

"The right foot is broken." Piedonshan was sweating profusely, and the stretcher was not working right now.

"Professor Pi, you have to turn sideways first. I will stretch my left lower limb, and it won't hurt very much. I'll lie down on my side first." Zhou Cheng knelt down on the ground as he spoke.

Traction, now there is no traction bed, the person is slumped on the ground, he can only use both hands to complete the traction at the same time!

Then he immediately said to the firefighters: "Cut the stretcher in the middle step by step! Then cut off a section of the steel bars at the front and back, as close to the flesh as possible. Then let the steel bars go into the broken opening, and carry it on a flat side for transport. "

"Then how do we do it in the car?" the emergency doctor who was transported hurriedly asked again.

There is only a kind of cart that can lie flat on the car. You can’t remove the bed, it’s easy to remove, but it’s not stable.

"When we get to the transfer vehicle, let's put something in the air at the front and back. There is no other better way." Zhou Cheng continued to think of a way.

People always have to be sent to the hospital first.

Piedenshan immediately said: "When you arrive at the hospital, open the abdomen immediately, mainly to detect the middle between the liver and the pancreas, and don't pull it out randomly."

Zhou Cheng was still pulling, but the big brother was heavy and it was a bit laborious, so he hurriedly told Yang Yifeng: "Yang Yifeng, take a small splint to fix it."

Yang Yifeng realized a long time ago that he did not go to the place where Zhou Cheng was going to run, but used a piece of steel bar that had just been cut off as a fixed object, and under the state of Zhou Cheng's traction, part of his lower limbs were lifted off the ground. , Wrapped up with gauze urgently.

Zhou Cheng lasted for 4 minutes before the firefighters finally clipped the two sides cleanly and took off a piece of the stretcher cloth.It happened that Yang Yifeng had completed the temporary fixation.

Only then did the crowd forcefully transfer the man onto the stretcher.

"Thank you." The patient's pain eased slightly, and he began to thank Zhou Cheng and others, and the emergency personnel immediately took him away.

Zhou Cheng sat on the ground, panting heavily, and was extremely happy in his heart. No matter what, it was good to be able to temporarily relieve the elder brother's pain and give him a chance to be transferred.

On-site first aid, the operations that can be done are limited.

It's just that Zhou Cheng almost fell on the ground before, his whole body was covered with dust, and his work clothes were stained.

Seeing this, Yang Yifeng only said: "Go over there and change another set. The dust is not good for the patients in the back. It's just a good time to take a rest."

Zhou Cheng nodded, adjusted his badge, and walked in the direction of Yang Yifeng, but this time, because of the badge, Zhou Cheng got into the car directly, and no one stopped him along the way, so he changed it. After taking off the clothes, jump off again.

Then Zhou Chengcheng saw that there was a direction, and he scoffed and shot a bloody flower into the air.

Chi Chi Chi!

Still spraying, like water spray.

However, the water splash is man-made, and the follow-up water volume is relatively infinite. The blood volume of the human body is at most about 8000ml, and the blood loss exceeds 20.00%, which is about 1500ml, and shock can be reached.

That is the amount of three bottles of ordinary mineral water.

The blood flower gradually decreased.

The heads and faces of a group of people next to them were covered in blood. After the blood sprayed against gravity, it dripped down again.

Tick-tick, like the sound of water drops.

But soon this silence was broken.

"Stop the bleeding, stop the bleeding, hurry up!" Someone grabbed the ruptured artery vigorously.

The people next to him hurried up to help!

Everyone was crowded together, Zhou Cheng really wanted to run over to see the situation, but after taking two steps away, he retreated and ran towards the direction where Yang Yifeng and the others were.

Follow orders!

He was with Peedon now, not a free man.

However, when Zhou Cheng arrived beside Yang Yifeng and the others, a very decisive voice sounded over there: "People are gone! This place cannot be saved."

"Go to the next one."

People are gone.

Zhou Cheng's heart trembled.

Although he had come into contact with many dead people in the hospital, it was the first time that his life disappeared in front of his face in such a situation.

Death is cruel and cold.
