"Yin Yuan, guess what good thing I saw today?"

As soon as Guo Shimin returned to Hospital 120, he happily ran to the dean's office.

Dean Yin was wearing a military uniform and a neat hat. The golden branches and leaves and a gold star on his shoulders were particularly eye-catching.

His temples were a little gray, and his Chinese-character face was calm and intimidating. He glanced at Guo Shimin and said calmly.

"I remember that you went to serve as a judge for the provincial equipment bidding meeting. What, did you find anything new?"

After saying that, he blew on the hot tea and took a sip.

Guo Shimin put a small silver stainless steel box in front of Dean Yin, and said with a smile: "I borrowed this for trial use. It is the new portable color ultrasound from Sanqing Group. It is a good thing."

With a click, the box was opened, revealing a complete set of equipment inside.

Dean Yin showed a playful smile: "Sanqing? The Sanqing that develops super hemostatic agents? They have entered the field of equipment? This is good news."

Guo Shimin quickly installed the probe, turned on the device, and was about to stick it on his neck.

"I tried it on site and it was really easy to use. It's such a small gadget that can produce 4D imaging. The most important thing is the price. How much do you think it costs?"

Dean Yin waved his hand and grabbed it, squinted his eyes and played with it carefully, then asked casually: "How much?"

"A high-end portable color ultrasound that only sells for 200,000 yuan! You say it's awesome or not."

Dean Yin's calm face finally showed a look of surprise: "Really?"

Guo Shimin nodded like a chicken pecking at rice and said: "Absolutely, I'm on the scene, but this is the wholesale price. You have to buy at least more than 100 units to get this price. If the quantity is small, the price should be

280,000.”

Dean Yin's face was even more surprised: "The price is indeed good, if the functions are as good as you said."

He pondered for a moment, put the color Doppler ultrasound instrument into the box, closed it with a click, then carried it and walked out.

Guo Shimin hurriedly caught up: "Dean, where are you going?"

"Go to the emergency room. I have to test the quality of this portable color ultrasound first."

"Okay," Guo Shimin rubbed his hands excitedly: "I have already learned this thing. I will get started later."

"Haha, step aside. With such a good thing, of course I should try it myself first." Dean Yin's hearty laughter echoed in the corridor.

"Ah?" Guo Shimin quickly reacted: "It's okay, you use it first, I'll just watch from the side."

While the two were talking, they had already arrived at the emergency room.

As soon as he entered, he saw an unconscious soldier lying on the hospital bed near the back, and his clothes and sheets were dyed red with blood.

A doctor stood next to him, examining the soldier anxiously, while the nurse hurriedly connected the sensor.

"Bidi, beep, beep..." The alarm sound of the monitor reached everyone's ears.

Dean Yin strode over and looked at the monitor first. His heartbeat was still there, but his blood pressure was relatively low. There was a visible wound on his abdomen, which was bleeding out.

"The bleeding must be stopped immediately!" At this time, the doctor had taken out some surgical instruments and was instructing the nurse: "Otherwise, he won't be able to hold on for long. Observe his vital signs closely and give him blood transfusion and fluid replenishment immediately."

"How was he injured?" Dean Yin asked another soldier standing next to him, who seemed to be the patient's companion.

The soldier looked at his epaulettes, immediately performed a military salute, and replied respectfully: "That's right, something happened to him during an actual combat exercise. A shrapnel entered his abdomen and he was bleeding. So we rushed him to the hospital."

Arrived at the hospital."

The doctor had already checked it over and said, "Yin Yuan, we don't know where the injury is at the moment. It may be necessary to open an laparotomy to find the hemostasis point."

Dean Yin also saw the condition of the wound. He only saw a blur and blood was still oozing out. He couldn't help but frowned and said, "I want to use equipment to check and see if I can roughly determine where the shrapnel is."

.”

The doctor was immediately shocked and said: "Dean, the patient may not be able to withstand the torture. It is better to have a blood transfusion first to avoid hemorrhagic shock."

Dean Yin put the box in his hand on the hospital bed, took out a portable color ultrasound, and said: "Use a portable color ultrasound. This should be effective. If you can't find the shrapnel, you won't be able to find the hemostasis point, and you will continue to lose blood. No matter how much blood you transfuse,

It’s no use either.”

The doctor hesitated and said: "Can color Doppler ultrasound work? This thing is not omnipotent."

General color ultrasound can examine the heart, liver, kidneys, and fetus, but it is still a little difficult to examine the stomach and lungs.

Because the cavities of these organs are filled with air, ultrasound waves cannot easily penetrate and reflect.

The injury to this soldier was right on his abdomen, which is a place that is not easy to check.

Moreover, the shrapnel rotates into the human body, and the final location where it stops is probably not at the external wound, but deep in the abdomen, making it even more difficult to find.

In the eyes of doctors, the top priority is blood transfusion first, and then abdominal surgery to stop the bleeding.

"Listen to me," Dean Yin said decisively. He quickly opened the portable color ultrasound, selected a large convex probe and installed it.

The large convex probe is larger than ordinary probes, and its curved surface is like an oval. Unlike other probes, which are all purely electronic devices, it has a motor inside, which will deflect the crystal to a certain extent, scan signals from various angles, and then

After synthesis, a three-dimensional image is obtained, suitable for exploring the abdomen and fetus.

After selecting the probe, he found that the system was easy to operate and quickly selected the high-frequency and high-current mode, which meant that the intensity of the sound waves emitted would also be greatly increased, allowing for deeper exploration.

However, this high-frequency mode should not be used for a long time, otherwise it will cause damage to the equipment.

Dean Yin is undoubtedly experienced. His fingers turned into an afterimage, operating the color Doppler ultrasound handle, and he is familiar with various angles and parameters.

As the probe moved around, bright shadows appeared on the screen.

Everyone stares at the screen and must distinguish in a very short time which part is displayed on the screen and whether this part is normal.

"It's almost time! Switch to pw mode and check the blood flow."

Dean Yin watched for more than ten seconds, and finally determined an area by distinguishing the condition of the wound. He immediately switched to the inspection mode and circled a location.

A red area instantly appeared on the screen, but there was no sign of backflow.

"The bleeding point is right here." The doctor said happily.

Guo Shimin and the soldiers next to him breathed a sigh of relief. It seemed that the bleeding point was about to be found.

Dean Yin couldn't help but nod. This portable color Doppler ultrasound is quite easy to use. He was also very lucky and found the bleeding point in less than a minute.

It is actually very difficult to find the bleeding point in the vast abdomen, because the internal organs are intertwined and can easily block people's sight.

However, in the face of high-definition and high-frequency color ultrasound, all bleeding points are invisible.

Dean Yin is very good at reading pictures and explained while operating.

"This is the location of the liver. The human liver has very rich blood supply and many arteries. The shrapnel entered from the right abdomen, passed through the intestines, and rubbed against the left liver lobe. You see there is an irregular bright spot here, which should be the shrapnel.

Already."

Even doctors, not everyone can read pictures. They need to be trained to understand. For example, the doctor in the emergency department stared with a confused expression on his face at this moment.

The brightness on the screen represents the power of the ultrasonic wave. This area is very bright, indicating that the reflection of sound waves is very strong. The shrapnel is made of metal, and its ability to transmit or reflect sound waves is much stronger than that of the human body, so it is naturally easy to distinguish.

"Now that we have found the location, can we stop the bleeding?" the soldier next to him asked anxiously.

Therefore, the patient has been bleeding for a long time now, and the companion is very worried.

"Now that the bleeding point is known, we can perform laparotomy to stop the bleeding." The doctor nodded and stood up to prepare for the operation.

"The patient seems to be in a bad condition." The nurse exclaimed.

Dean Yin took a look at the monitor and found that his blood pressure and body temperature were beginning to drop. He immediately said decisively: "It's too late. Use a cotton ball to press it first to stop the bleeding, and then send him to the operating room immediately."

Then he said to the doctor: "You do the operation, hurry up, otherwise the patient will go into shock immediately. I will use color ultrasound to point out the specific location for you."

The doctor opened his mouth in surprise. Is this okay?

But he didn't say much, and immediately picked up a pair of long clamps. After disinfecting, he picked up a large piece of sterile gauze and carefully inserted it through the wound on the patient's abdomen.

Using a hemostatic gauze with a device to press the bleeding point may not fundamentally solve the problem, but it can temporarily stop the bleeding.

But in this case, the internal situation cannot be seen, and it is difficult to place the gauze on the correct bleeding port.

Only by using color Doppler ultrasound to guide the path, can the bleeding operation be completed without opening the stomach.

Just like doing amniocentesis in the past, if you can't see the internal condition and perform the operation directly, it is easy to hurt the baby and it is very dangerous. However, with the guidance of color ultrasound, the safety of the examination has been greatly improved.

Both are the same.

Dean Yin placed the probe on the abdomen again, and a bright spot appeared on the screen, which was the clamp in the doctor's hand.

Fortunately, he is very familiar with the human body's organs. He knows where there are organs and which places are relatively empty.

So within the field of view given by the color ultrasound, the doctor was constantly guided to avoid the intestines skillfully, and gradually extended the hemostatic gauze to the bleeding point.

This doctor's basic skills are also very solid. Although his movements are very slow, only extending one or two millimeters inward each time, his hands are very steady and do not tremble at all.

Dean Yin has to switch to pw mode every few seconds to check the location of the bleeding point, and then switch to b mode to guide the doctor to the bleeding point. It can be said that he is very busy.

The probe moves with the position of the clamp, and it must judge the situation from the image as quickly as possible and provide precise assistance.

When the doctor stops moving, he will switch to 4D mode to let everyone take a closer look at the situation inside the abdomen.

A minute passed, and the hemostatic gauze was finally brought to the bleeding point and pressed gently.

Without giving any indication, Dean Yin quickly switched to pw mode to check if bleeding was still occurring.

At this critical moment of life and death, the two of them cooperated quite well.
