First aid seems to be just two simple words, but it represents so much.

The process alone can be divided into on-site first aid, transport first aid, and in-hospital first aid.

In-hospital first aid can be divided into emergency department treatment and specialist treatment!

After the patient arrives at the hospital, there are enough specialists to conduct specialist consultations in various subspecialties, and only then can he be able to receive the best medical conditions.

Before in-hospital emergency treatment, whether on site or in transit, medical resources were limited.

Just like now, even if the expert medical team is formed with the efforts of the entire province, there is no guarantee that every patient will have the most official and authoritative doctors in all specialties to deal with it immediately.

It’s not that there aren’t so many people, it’s not that we can’t find so many people temporarily, but.

The space is limited and if there are too many people, it will be very crowded, which will affect and delay the first aid process!

However, all kinds of first aid have only one purpose.

Save your life, save your life, save your life!

Save lives first, then treat the disease, this is an eternal topic in emergency and first aid.

Before the patient reaches subspecialty, all efforts are made to save life.

In first aid, one of the biggest life threats is shock, especially hemorrhagic shock!

Hemorrhagic shock, strictly speaking, is a process of cumulative and continuous blood loss over time. That is to say, for every extra second of delay, your heart will pump out circulating blood, and then in the process of rupture.

At the mouth, blood leaves your body, gradually reducing the amount of blood circulating throughout the body.

If a little adds up to a lot, it will kill you.

Therefore, time is also life and is an eternal topic.

However, if the bleeding can be stopped during on-site first aid, the risk of shock will be greatly reduced. The 120 ambulance for transfer can complete the replenishment process of circulating blood volume, which can maximize the risk of shock.

Wait until you go to the hospital and receive treatment from a specialist.

Save a life.

Life is the most precious thing.

After Yang Yifeng heard Zhou Cheng's words, he took a small step back and asked, "What are you going to do?"

What Zhou Cheng wants to do is actually blood vessel exploration + hemostasis.

To stop bleeding, there are physical hemostasis, electrocoagulation, and other methods to stop bleeding, but what Zhou Cheng wants to do is even more extreme, directly tying off the blood vessels to stop the bleeding!

This is a very effective mechanical coping factor. It may seem violent, but it is also one of the charms of modern medicine.

The most simple and intuitive expression is——

In ancient times, giving birth was a hurdle for women to overcome with their lives. There were two main risks: amniotic fluid embolism and postpartum hemorrhage.

The probability of embolism is not high. Even if it occurs, the size of the embolism must be considered, and then PCI and other measures will be taken.

However, for massive postpartum hemorrhage, with the help of intervention, the corresponding arteries can be embolized, which greatly reduces the maternal mortality rate. This is the most intuitive manifestation.

Zhou Cheng now wants to tie off the brachial artery, which is actually the same idea.

However, if blood vessel exploration is done in the operating room, any orthopedic graduate student can do it, but this is on site!

The conditions are simple and various factors are mixed. There is not even an electrocoagulation knife used to stop bleeding. And when doing arterial exploration, one of the risks you need to face is cutting the aorta and veins, accelerating bleeding and accelerating shock!

Zhou Cheng had already put on gloves at this moment, pointed to the small bottle of iodine complex next to him, and said: "Disinfection, small incision, blunt penetration of the muscle gap, and clamping. If the whole process goes well, it may only take more than a minute.

time."

"Without the intervention of sharp knives and round knives, the risk of vascular forceps breaking blood vessels is smaller!" Zhou Cheng said this to Piden Shan.

Pidenden is now the leader of this team, and Zhou Cheng is the assistant called by Yang Yifeng. Therefore, if he wants to operate, he must first obtain Pidenden's consent.

When Pideng heard that it only took more than a minute, he immediately said: "Doctor Zhou, hurry up and do it. If you can buy more time, then the fire department will have enough time to save the hand."

After hearing this, several firefighters nearby said: "If we have enough time, we can still take out our hands if we give us twenty minutes."

It's not impossible, I just heard that if this person is not rescued in time, he will die.

Over twenty minutes, who knows how much more blood he will bleed?

What's the point of saving the person's hand after he's dead? They then asked their superiors for instructions and sent a team of experts over. They originally said they were going to amputate the limb and drag the person away, but the scene of the amputation on the spot was still quite disturbing.

Although they have seen it before, they don't want to see it again.

Yang Yifeng didn't say anything. After hearing Pidenden's words, he silently poured iodine complex near the deltoid muscle. The patient's clothes had been cut open, and the purple-red iodine complex instantly stained the tear in the clothes.

Strange colors.

After finishing, Yang Yifeng used sterile gloves and sterile gauze to wipe it and disinfected it roughly three times.

He took a half step back and stretched out his head to see how Zhou Cheng was operating.

Zhou Cheng's words were simple, and Pidenden's reply was also simple, but only Yang Yifeng was brainstorming at the moment.

How to bluntly open the muscle gap under a small opening to reach the arteries and veins, and how to separate the arteries and veins without clamping the nerves, are all key points.

More than a minute?

In five minutes, if Zhou Cheng can complete all this, it will be.

While Yang Yifeng was still making calculations, Zhou Cheng quickly found the positioning mark with his hands rather rudely, and then made a two-centimeter incision, cutting into the fat layer under the skin, and then.

Blood seeped out and soon covered the wound.

Zhou Cheng didn't hesitate, and immediately used the vascular forceps to dig around the lower layer of fat. After taking out a certain gap, he saw that the vascular forceps in his hand seemed to have eyes, and the tip penetrated deeply!

Then Zhou Cheng swung his tail a few times again, then swung it left and right in the direction of the incision, seemingly breaking the fascia between the muscle layers!

Zhou Cheng's left hand inserted a vascular forceps again, close to the position of the vascular forceps on his right hand. After also sending the vascular forceps in, he opened the vascular forceps with one hand and opened the gap inside.

It's the vascular forceps that are sent in later.

"Click!" The clamp closed with a sound.

After doing this, Zhou Cheng took a deep breath!

Just now, the axillary vein was clamped with assistance!

However, if there is another vascular clamp, there will be no assistance.

There are only two pairs of pliers in one bag, not much.

Under the mask, he licked his lips with his tongue, then moved it slightly outward and behind along the clamped blood vessel forceps!

Veins are outside and behind arteries.

After carefully opening the head of the vascular forceps, he carefully poked inside. Because there is a layer of axillary sheath outside the axillary artery and axillary vein, this tough sheath must be broken open to accurately clamp it.

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

After clamping it shut again, Zhou Chengcai slowly breathed a sigh of relief.

Then he opened the previous wound position and tore off a small part of the gauze. After seeing that the bleeding was almost non-existent, and the small amount of bleeding was just residual blood, he said: "It's okay, the bleeding has stopped temporarily.

Already."

Zhou Cheng said this to Yang Yifeng and also to Pideng Shanshan.

"Take your blood pressure! Continuously monitor it. If the blood pressure is wrong, report it immediately." Pideng Shanshan immediately said to a nurse in green clothes next to him.

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

At the same time, several firefighters looked at the pliers placed on the patient's arms and asked, "Is this enough? It may take more than twenty minutes here!"

Are you kidding me? This metal thing is put inside the human body and cannot be removed?

Isn't this equivalent to stabbing him directly?

Hey, it really looks like two pairs of pliers were used to stab this man's arm.

However, doctors are the only profession among all professions that can directly operate on the human body for normal therapeutic purposes without being charged with intentional harm or injury.

Yes and only, apart from this, any other profession, including forensic medicine, as long as the knife is used on a living person, it is intentional harm!

Forensic doctors can only operate on dead people.

"If the bleeding stops, it should be fine in more than 20 minutes." Although Pideng is not an orthopedic surgeon, he is still a surgeon. After the artery is clamped and the blood loss is limited, it is equivalent to only the blood vessels in the hand being blocked.

Living.

The most likely outcome is amputation, but you can gamble on the chance of saving the limb and make a profit.

Now we can't do it perfectly, so we have to do this.

"Thank you for your hard work. When people come out later, you must contact the stretcher in advance and tell the doctor who is transferring you that these two pair of forceps must not be moved until you enter the operating room!" Pideng Shanshan participated in the scene more than once.

rescue work, so he is also a very brave person.

"We have other tasks, please excuse me. Xiao Zhou, you stay here, the others follow me and continue to rescue other seriously ill patients." Pideng said hurriedly.

"Okay." Zhou Cheng replied, thinking that he could only shoulder the task of watching and paying attention to the patient's vital signs.

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