Chapter 854

"Secretary Ren, come on, you divide into two groups to correct the shock. Director Zhao, you and Lao Chen, Lao Wang, you and me. Come on, go to surgery first."

Zhang Fan gives orders to Ren Li, the director in his heart, and Zhao Quanping, the director of general foreign studies.

This traumatic shock must not be vague. Any examination or conversation must be delayed.

Every minute can't be delayed. At this time, what doctors protect themselves and worry that doctors will be involved in patients' accidents.

At this time, they don't even think about it. This is responsibility, this is responsibility.

If at this time, he still cares about the consequences and is afraid of taking responsibility, the doctor will wear a white coat in vain.

At this time, the bleeding must be stopped while correcting the shock.

People's sympathy and compassion are actually like feelings. For example, compared with other industries, doctors and police have a higher threshold of sympathy and compassion.

They are used to seeing life and death parting and the dangers of the world. The longer you work in this industry, the more Facebook you will become.

For example, even if a policeman retires, he knows that he can't escape the public security law when he looks at his face.

The same goes for doctors.

This sublimated perception is different from people's innate perception, such as touch.

People's emotions are less and less used, and the touch feeling is more and more sensitive, such as touching the package of the human body.

Skilled people can feel it when the diameter of the package is one centimeter.

Not for unskilled people. It is estimated that the package will be a little bigger to feel it.

Although it is a little bigger, it is often a little worse when the mass changes from benign tumor to malignant tumor.

Of course, Zhang Fan's current sensitivity can be perceived when the package is about 0.8cm, which is comparable to color Doppler ultrasound.

This is the experience from a large number of physical examinations. For example, sometimes when he goes to bed at night, Zhang fan can't help doing a breast examination for Shaohua.

This is subconscious, but in fact, this test should be mastered by every man.

Don't men like big and plump. In fact, the larger the breast, the easier it is to grow breast tumors.

This kind of inspection is very simple, not too difficult, and the technology is not too profound. It can be said that as long as you have one hand.

Everyone has rubbed oil on their faces. In fact, this inspection is like this. The four fingers are close together, starting from the armpit, the four fingers exert a slight force, and the finger abdomen probes into the fat.

Then start from the armpit and move down slowly. It should be slow. Of course, experienced ones can be a little faster.

Open from the armpit, start to turn around the breast, and finally pinch the five fingers at the small pimple in the center to feel whether there is a foreign body.

Really, don't look like it's very funny. In fact, when you are free, this check not only regulates the feelings between husband and wife, but also prevents trouble for your lover.

It's definitely a good thing to kill two birds with one stone.

Don't just be hungry like a child. You don't have any technical content at all.

This sensitivity can be exercised the day after tomorrow, and the human body is also particular about the loss of blood.

Most of the deaths caused by trauma are often due to shock.

It can be said that shock is the real culprit. In fact, many human diseases have serious consequences because of blood.

For example, AIDS, the three ways of transmission, in fact, when you think about it, are all related to blood. Why not say kissing, but physical education?

This is because the cell membrane falls off between friction, leading to the rupture of superficial capillaries, so the virus enters the blood vessels.

It is the entry of the virus that causes an infection in the blood.

And how much can bleeding be fatal.

In normal adults, the weight of blood accounts for about 7% to 8% of body weight. Under normal circumstances, this proportion is constant and generally does not exceed 10%.

When the blood loss does not reach 8% of the blood volume, in fact, this blood will not have obvious clinical symptoms for the body.

When people constrict their blood vessels, they will raise their blood pressure to a normal level, so the vascular system of the body is very good.

When the blood loss is 10% of the weight, the body fluid in the body enters the blood vessels and acts as a filler for vascular pressure.

Then the liver quickly synthesizes albumin, which can be said to recover in a day.

The body is not afraid of chronic blood loss.

For example, a female's period, a cycle, is about 100 to 300 ml of blood, which varies more or less from person to person.

In a week's time, to tell the truth, this blood is estimated to have not flowed clean. The body's metabolism has come again.

This is also the reason why women have no abnormal physical discomfort during physiological period.

This is also the reason why women have syncope on the first day and at the beginning of the second day.

The loss is too fast, and the body can't compensate.

And this physiological chronic blood loss can also stimulate the regeneration of blood vessels. Therefore, the elasticity of blood vessels in women who have not entered menopause is better than that in men.

Cardiovascular disease is much lower than that of men, which is why men are extremely prone to sudden death. There is no period!

The body is really not afraid of chronic blood loss. Sometimes, when the loss of blood is as high as 30%, the body will have shock.

However, when rapid blood loss occurs, it is different. There is no need to lose much in this situation. Once it exceeds 10%, shock will occur.

Because at this time, the body's compensation mechanism can no longer achieve the function of balancing blood pressure. First, blood pressure can't get up.

Many people have heard of shock, but what is shock? In fact, commonly speaking, it is an obstacle to blood perfusion.

There are many types of shock, such as blood loss.

And severe diarrhea and vomiting. Especially children, in their early years, many children often died of diarrhea and high fever.

Now it seems that diarrhea is not serious because the medical environment and sanitary conditions have improved a lot.

Now diarrhea pulled off the anus seems to be the most serious situation.

To tell you the truth, anal prolapse can't kill anyone. But a large amount of fluid loss can kill people every minute. In fact, severe diarrhea is more popular. In fact, it is similar to the effect of arterial rupture and bleeding.

In the past, once there was diarrhea, it was that black and white impermanence had stood by people.

In addition to blood and fluid loss, there are burns, infections, cardiac dysfunction, allergies and strong nerve stimulation.

These can lead to shock. In fact, take a closer look, although the etiological mechanisms are different.

The consequences are the same, which is to cause obstruction of blood flow. Allergy, a large area of allergy, can lead to increased vascular permeability.

Just as after bees sting people, why do people swell up like hair all over their heads.

In fact, bee stings make the body produce a lot of factors that fight with allergic substances.

A fight between allergic substances and these factors eventually led to the blood vessels, which were originally silk stockings, suddenly turned into fishing net stockings.

Then all the blood ran from the blood vessels to the cells, and the human body quickly became a big steamed stuffed bun like a balloon filled with water.

Strong nerve stimulation will make capillaries spasm, and then blood reflux problems, and then turn into shock.

For example, some people will feel dizzy and numb after strong laughter and strong crying. In fact, this is the early stage of shock.

Laugh to death. This is not nonsense. This thing makes sense.

How to correct shock is actually to find a way to make the perfusion sufficient.

For example, in case of blood loss, a balanced salt solution with an estimated blood loss of two to three times shall be injected intravenously.

In fact, this is to stabilize the acid-base balance of the body with a balanced salt solution, and then cheat the body with this liquid to raise its blood pressure.

Lose blood, but the body's acid-base balance and blood pressure can't be corrected.

Then, this is directly the comprehensive collapse of the reservoir dam and the damage of various organs. Once this result occurs, the Jade Emperor will have no choice.

So, at this moment, the awesome nurse shows her importance.

Blood vessels, the blood vessels of normal people, are actually like a powder bar. They are full and smooth. Nurses with poor skills sometimes can't get in.

Why? Because this thing is smooth, it can avoid. When a sharp tool is inserted, the outer membrane of the blood vessel is as smooth as the mucus on the fish. It can avoid to a certain extent.

Often some nurses plunge in and look back and take out again. The patient with pain shows his teeth. This is the blood vessel. After avoiding, the nurse returns to the needle.

The ischemic blood vessels are actually stuck together like two pieces of white paper. At this time, it is much more difficult than being smooth. There is no chance to look back and take out. You must hit them with one blow, or you have to find blood vessels in another place.

To make a simple analogy, put a piece of pork on two pieces of paper and give you a needle.

I ask you to pierce the pork and pierce the first layer, but you can't hurt the second piece of paper.

Moreover, you have to let the needle move forward in the gap between paper and paper.

To tell you the truth, you may not be able to do it when you are calm.

Nurses, after this time, the flat car runs fast. Nurses not only have to keep up with the speed of the flat car, but also pierce the needle.

Really, it's all blood and tears and the ability to slap in the face.

The head nurse of the emergency center, the head nurse of the operating room, the head nurse of the orthopaedic department, the head nurse of the cardiology department, the head nurse of the respiratory department.

It can be said that almost all the most skilled nurses in the hospital came, four people, a flat car, both upper and lower limbs.

They bend over and lower their heads, grasp the patient's arm or ankle in one hand, and hold a needle in the other hand. They must move quickly under the soles of their feet to keep up with the speed of the flat car.

Why can't the step be too big? It's not afraid of pulling the egg, but the hand is unstable when the step is big! To tell you the truth, this industry is too bullshit.

While the situation is urgent, I have to listen to Zhang Fan's urging voice: "is the venous channel open? Come on, if you can't, go away, I'll come!"

Really, not even two minutes. The head nurse's nurse hat is full of sweat. It's nervous and urgent. What's more, it's a sports war.

Really hard!

Although the head nurse in the operating room seems to have an affair with Zhang Fan, which is the way of life of others in the workplace.

Zhang Fan never takes it seriously. He not only can't take it seriously, but also pretends to be shy and avoid it.

If he really takes it seriously, the head nurse may slap him in the face!

The head nurse in the operation room looked at the monster, stealing perfume and lipstick every day, but the technology of others was really good.

The first one opened the vein of the man's upper limb. While running, the head nurse in the operating room shouted, "the vein channel of the right upper limb has been opened!"

The charming sound of the female voice, especially in this crisis, is so beautiful, especially the head nurse's voice is so charming!

One, two... Eight venous channels for a man and a woman, like Teletubbies, were all erected before entering the elevator.

The suspended liquid is bubbling and has quickly entered the patient's body. This is the ability, which is the embodiment of a hospital's comprehensive ability.

They and they are the mainstay of the hospital.

The police car came and went, and then in a hurry, the patient was sent to the operating table.

"Come on, Lao Li, I'll disinfect. You can lay sheets and anesthesia at the same time. You can't wait."

The main knife of male surgery is Zhang Fan, and the main knife of female surgery is the director of general surgery and the director of cardiothoracic surgery.

The operation begins!

The heavier the rain, a trace of red can be seen on the street.

However, sadness cannot be washed away by heavy rain.
