"Secretary Ren, come on, separate two groups and start correcting the shock. Director Zhao, you and Lao Chen will be in one group, Lao Wang, you and I will be in one group. Come on, let's do the surgery first."

Zhang Fan gave orders to Ren Li, the director in his heart, and Zhao Quanping, the director of general surgery.

This kind of traumatic shock must not be vague. All examinations and interviews must be postponed.

There can be no delay for a minute. At this time, what is the doctor's self-protection and what is the worry that the doctor will be implicated if the patient has an accident.

At this time, they would not even think about it, this is responsibility, this is responsibility.

If at this moment, you are still worried about the consequences and afraid of taking responsibility, then this doctor is wearing his white coat in vain.

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

Human sympathy and compassion are actually just like feelings, they are limited. For example, doctors and police officers have higher thresholds for sympathy and mercy than other professions.

They are used to life and death and the dangers of the world. The longer they work in this industry, the more they become familiar with their faces.

For example, even if you have retired as a police officer, one look at his face and you will know that you cannot escape the law of the police.

The same goes for doctors.

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

People's emotions become less and less the more they are used, while the sense of touch becomes more sensitive the more they are used, such as touching the lumps on the human body.

A skilled person can feel the mass when it is one centimeter in diameter.

Unskilled people can't do it. It is estimated that the lump must be larger to feel it.

Even though it looks a little bigger, often when a mass changes from a benign tumor to a malignant tumor, it is actually just a little bit different.

Of course, with Zhang Fan's current sensitivity, he can detect masses at around 0.8cm, which is comparable to color Doppler ultrasound.

This is the experience gained from a large number of physical examinations. For example, sometimes when sleeping at night, Zhang Fan can't help but do a breast examination on Shao Hua.

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

Don’t men like to be big and plump? In fact, the larger the breasts, the easier it is for breast tumors to grow.

This kind of inspection is very simple, not too difficult, and the technology is not too profound. It can be said that all it takes is one hand.

Everyone has rubbed oil on their face. In fact, this examination is like this. Put your four fingers together, starting from the armpit, apply slight pressure with your four fingers, and explore the fat with your fingertips.

Then start from the armpit and move downward slowly. Of course, experienced people can go a little faster.

Start from the armpit and make a circle around the breast, and finally pinch the small lump in the center with five fingers to feel if there is any foreign body.

Really, don’t think it sounds particularly funny. In fact, when nothing happens, checking like this can not only regulate the relationship between husband and wife, but also prevent your lover from problems before they happen.

It's definitely a good thing that kills two birds with one stone.

Don't just act like a hungry child, there is no technical content at all.

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

Deaths caused by trauma are often caused by shock.

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

For example, AIDS has three transmission routes. In fact, if you think about it carefully, they are all related to blood. Why not talk about kissing, but talk about physical education?

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

This is where the virus enters and causes an infection in the bloodstream.

How much bleeding does it take to be fatal?

For a normal adult, 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%.

As for the blood loss, when it does not reach 8% of the blood volume, in fact, for the body, this amount of blood will not cause obvious clinical symptoms.

Once the blood vessels are constricted, the blood pressure will be raised to the normal level, so the body's vasculature system is very powerful.

When the blood loss reaches 10% of the weight, the body fluids enter the blood vessels and act as fillers to increase vascular pressure.

The liver then rapidly synthesizes albumin, so to speak, and can recover within one day.

The body is not afraid of chronic blood loss at all.

For example, a woman's menstruation, a cycle, is about 100 to 300 ml of blood, more or less different from person to person.

In a week, to be honest, this little blood probably hasn’t been drained out yet, as the body’s metabolism has already gone through another cycle.

This is also the reason why women do not experience any abnormal physical discomfort during their menstrual period.

This is also the reason why women suffer from fainting when the blood flow becomes more intense on the first day of a woman’s menstrual period and at the beginning of the second day.

It is lost so quickly that the body cannot compensate.

Moreover, 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. This is why men are extremely prone to sudden death. They don’t have periods!

The body is really not afraid of chronic blood loss. Sometimes, when the blood loss reaches up to 30%, the body will go into shock.

However, it is different when rapid blood loss occurs. In this case, you don’t need to lose much. Once it exceeds 10%, shock will occur.

Because at this time, the body's compensatory mechanism can no longer achieve the function of balancing blood pressure, and first the blood pressure cannot rise.

Many people have heard of shock, but what exactly is shock? In layman’s terms, it means an obstacle to blood perfusion.

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

There is also fluid loss such as severe diarrhea and vomiting. Especially for children, many children often die from diarrhea and high fever in their early years.

Everyone now thinks that diarrhea is not serious. That is because the medical environment and sanitary conditions have improved a lot.

Nowadays, diarrhea and prolapse of the anus seems to be the most serious situation.

To be honest, anal prolapse cannot kill people. However, a large amount of fluid loss can kill people in minutes. Severe diarrhea, in fact, in layman's terms, is almost the same as the blood spurting caused by a ruptured artery.

In the past, once diarrhea occurred, it was equivalent to black and white and impermanence standing beside the person.

In addition to blood loss, fluid loss can also include burns, infection, heart dysfunction, allergies, and strong nerve stimulation.

All of these can cause shock in the human body. In fact, if you look carefully, the causes and mechanisms of these are different.

The consequences are the same, which is to cause obstruction of blood flow. Allergies, large-scale allergies, will lead to increased vascular permeability.

Just like after a bee stings a person, why does the person's face become swollen like hair all over his head?

In fact, it is because the bee sting causes the body to produce many factors that fight against allergic substances.

The fight between allergic substances and these factors will eventually cause the blood vessels that were originally stockings to suddenly turn into fishnet stockings.

Then all the blood flows from the blood vessels to between the cells, and the human body is like a balloon filled with water, quickly turning into a big bun.

Strong nerve stimulation will cause capillaries to spasm, and then there will be problems with blood return, and then it will turn into shock.

For example, some people may feel dizzy and numb all over after laughing or crying violently. In fact, this is the early stage of shock.

This is ridiculous, this is not nonsense, this stuff makes sense.

Correcting shock, exactly how to correct it, is actually to find a way to make the perfusion sufficient.

For example, if it is a hemorrhagic condition, a balanced salt solution that is two to three times the estimated blood loss amount should be given intravenously first.

In fact, this is to first use a balanced salt solution to stabilize the body's acid-base balance, and then use this liquid to trick the body into raising its blood pressure.

Once blood is lost, the body's acid-base balance and blood pressure cannot be corrected.

Then, this is directly a complete collapse of the reservoir dam, and various organs are damaged invariably. Once such a result occurs, the Jade Emperor will not be able to do anything when he comes down.

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

Blood vessels, normal human blood vessels, are actually like vermicelli, plump and smooth, and even nurses with poor skills may not be able to penetrate them sometimes.

Why? Because this thing is sleek and can dodge. When a sharp weapon is inserted into it, the outer membrane of the blood vessel is like the mucus on a fish. It is slippery and it can dodge to a limited extent.

Often some nurses insert the needle, only to turn around and take it out again. The patient grimaces in pain. This is because the blood vessel has been avoided and the nurse returns the injection.

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

Blood vessels.

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

You are asked to pierce the pork, pierce the first layer, and not damage the second piece of paper.

Moreover, you are required to move the needle forward through the gap between the paper and the paper.

To be honest, when you are asked to calm down, you may not be able to do it.

As for the nurses, after this time, the flat car was running very fast. The nurses not only had to keep up with the speed of the flat car, but they also had to put the needle in.

Really, this is all acquired through blood, tears and slaps.

The head nurse of the emergency center, the head nurse of the operating room, the head nurse of the orthopedics 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 are here, four of them on a flat car, with both upper limbs and lower limbs.

They bent over, lowered their heads, grabbed the patient's arm or ankle with one hand, and held the needle with the other. They had to move quickly with their feet to keep up with the speed of the flat car.

Why can't you take too big a step? It's not because you're afraid of making a mistake, but because if you take a big step, your hands won't be stable! To be honest, this industry is too nonsense.
To be continued...
