Director Jiang gave up his position: "Come here, Xiao Yang, look at the color ultrasound image, the catheter is close to stenosis, I began to plan to go to the interventional operating room to do it, the interventional room is monitored, but I don't dare to move the patient again, move it a little, and the blood oxygen will fall immediately." ”

Although there is no X-ray monitoring in the intervention room, it is better to have color ultrasound monitoring than to go over the stenosis with bare hands, Yang Ping said to the color ultrasound doctor: "Just maintain this position, don't move, I will start to push the tube now." ”

The color ultrasound doctor's hand is very steady, fixed in the position that Yang Ping thinks is very good, he sits on the edge of the bed, because he can't compress the abdomen, his hand is hanging in the air, so it is very hard, in order to maintain stability, he holds the hand holding the probe with his other hand.

"Miss Ning, can you please go out for a while?" Yang Ping said.

When the doctor does the operation, the family members are generally not allowed to be present, because sometimes the family members will interfere with the operation, especially at a critical moment, the family members do not understand the principle of the operation, it is easy to misunderstand, and once interfered, it is easy to have an accident.

Miss Ning hesitated, reluctantly left the ward, and said to Yang Ping when she left, "Please!" ”

Yang Ping nodded firmly at her.

"Be careful! Xiao Yang, the blood vessel wall is very thin, and it will break if you poke it slightly. The deputy chief physician of the Department of Vascular Surgery reminded him that it was entirely out of the kindness of his colleagues.

Director Jiang suggested on the side: "Should you withdraw the catheter, use interventional tools to send in a vascular stent, stretch the stenosis open, and then reinsert the catheter?" ”

This method is good, but there is no way to use it now, the catheter cannot be withdrawn, once withdrawn, the circulation of the entire human body is interrupted, and Mr. Ning's own lungs have no function at all, so the direct consequence is that the dominoes collapse, and there is multiple organ failure, and it is useless to save it.

"The stenosis can just pass through the tube, as long as the direction is adjusted, it should be through, the tube can't be retreated, once it retreats, the blood oxygen will plummet!" Yang Ping stared at the color ultrasound screen and said.

Director Jiang stopped talking, Yang Ping was right, as soon as the tube was withdrawn, before the new tube was inserted, the patient's blood oxygen would be extremely low, causing ischemia of brain tissue, and then causing multiple organ failure.

Color ultrasound cannot replace the feel, not to mention that the image displayed on color ultrasound is flat and distorted.

According to the length and state of the exposed part of the catheter, Yang Ping judged the depth of the catheter and the state it was in at this time, and he gently pinched the catheter with his thumb, index finger and middle finger, and three fingers, and rotated it very gently.

Retreating about a centimeter successively, the image in his mind was a little blurry, Yang Ping strengthened it again, making it clearer, because the composition was too difficult, sweat oozed from his forehead, and he tried to replenish it a few times before the image was clear.

Just like ordinary people remember an object and keep it in their minds, it will be clear at first, but after a while, it will be blurry, especially the details, and they can't recall it at all.

"Xiao Yang! If not, don't force it--"

Director Jiang was worried that the newborn calf was not afraid of tigers, and it was not a good thing that the newborn calf must not cause heavy bleeding and die on the spot, even if the family did not pursue the case.

"Don't worry, I know it." Yang Ping said.

The catheter gently goes up and touches the stenosis, and the slight contact between the catheter and the stenosis is transmitted through the catheter to the hand, which makes fine adjustments based on this indirect tactile feedback, like threading through the eye of a needle.

Little by little, while passing and adjusting, everyone stared at the color ultrasound screen.

"No, I can't hold my hands anymore." The hanging hand of the doctor was a little trembling.

Yang Ping immediately gently stepped back the pipe: "You let go of your hands, take a rest, I'll wait for you!" ”

After resting for a while, the ultrasound doctor's probe pressed down again.

Yang Ping's hand holding the catheter just now did not move, and waited until the image of the blood vessel and the catheter reappeared in the color ultrasound image, and his hand adjusted the tube again, and the tube began to slowly cross the stenosis.

The blood oxygen fluctuated sharply, and it dropped suddenly, Mr. Ning was a little restless, and the tube in Yang Ping's hand retracted again, extremely dexterous, and did not touch the blood vessel wall.

"Give me some more sedative medicine!"

There was an anesthesiologist next to him, who had not made a sound, and he only went on when he needed to.

The stenosis can just pass through the catheter, and if the direction is a little off, it will not be able to pass, and if the patient is agitated, the catheter will most likely puncture the blood vessel.

The risk of passing slowly like this was too high, and Yang Ping decided to seize the opportunity to pass quickly.

At this time, I don't know when Director Han also came in, it should be Director Kong who called him, after all, the person who borrowed him to do high-risk operations without informing him how to do it.

When Director Han heard the news at home, he immediately rushed over, no matter how powerful Yang Ping was, he could come over and help come up with ideas.

"Director!" Yang Ping greeted Director Han.

Director Han nodded slightly, meaning that you continue to do it, don't be distracted.

After saying hello to Yang Ping, Director Han walked to the reading lamp to watch the film, studied it for a while and said:

"Xiao Yang, in this case, it's best to pass quickly, but the risk is extremely high, but it's better than passing slowly."

This idea coincides with Yang Ping.

"Call Miss Ning in!" Yang Ping wanted to talk to her about the risk, which could only be a gamble. It's done! Mr. Ning can hold on for a few more days, or even dozens of days; Not! It may be that the heart beats and breathes at this moment.

Director Kong knew what Yang Ping meant, and said: "I talked about it carefully before the operation, the risk is extremely high, and I may stop my heart and breathing immediately." ”

Yang Ping still insisted that it was necessary to talk: "I'll talk to her again." ”

Director Kong called Miss Ning in, Miss Ning had been in the corridor just now, very nervous, although she had been mentally prepared for a long time, but when it came to this juncture, she still couldn't accept it.

"Miss Ning, now this catheter must pass through the stenosis, otherwise Mr. Ning will not be able to survive today, but the risk of crossing this stenosis is very high, I have to seize the opportunity to quickly send the tube now, success or failure is a second of time, there is only one chance. It's done! Mr. Ning can hold on for a few days, or even dozens of days; Defeated! It may be that the heart beats and breathes stop on the spot. I'd like to hear your opinion, are you willing to take the risk--"

Now that the anesthesiologist gave the sedative medicine, Mr. Ning couldn't make a statement, he couldn't even nod his head, Miss Ning was in a dilemma, her facial muscles trembled, and her lips wanted to open several times to speak, but she only moved slightly and didn't speak.

"We don't have a lot of time, and the oxygen pressure we are given now is very high, so we can't give this pressure for too long!" Yang Ping said calmly.

If you don't take risks, you can't stand today, it's no different from stopping jumping on the spot, my father wants to drag it, just to see my younger brother, Miss Ning analyzed in her heart.

Although she is young, she has been in the mall for several years, and she is calmer than ordinary people, and she is more able to seek advantages and avoid disadvantages.

"How sure are you?" Miss Ning asked.

Yang Ping shook his head: "It's hard to tell!" ”

Miss Ning gritted her teeth and said decisively: "Doctor Yang, I believe in you, even if you let go and fight, I am willing to take risks, no matter what the consequences are, I am willing to accept them." ”

"Okay, I see, you go out and wait again!" Since the family is willing to take the risk, they will take a gamble.

However, Yang Ping still knows in his heart and has a great grasp, but this kind of thing must be explained clearly to the family, and he can't say it too surely.

Miss Ning went out, and the door to the emergency ward was closed again by a doctor.

"Can color ultrasound still hold on? If it doesn't work, you let go and take a break. Yang Ping said to Dr. Caichao.

The ultrasound doctor said, "You can hold on!" ”

"Hold it for 30 seconds and don't move, I can finish feeding the tube, it must not move, it's better to take a break." Yang Ping saw that he had held on for a while.

"Okay!" The ultrasound doctor withdrew the probe and began to move his wrist, which was sore.

After resting, he picked up the probe again and pressed down on the right side of the lower abdomen, and when the image was in the best state, he froze the movement.

"Okay, don't move!"

Yang Ping and Dr. Cai Chao confirmed their eyes.

"Steady, look for opportunities, and pass once!" Director Han encouraged.

Everyone held their breath, stopped talking, and stared at the color ultrasound screen.

The doctor clenched his teeth tightly, and his hands did not move, like a sculpture.

The screen is very stable, without a hint of shaking, and the red and blue colors that represent blood flow flicker.

Yang Ping adjusted his breathing, pinched the catheter in his hand, not loose or tight, adjusted to the best direction, and broke through!

In an instant, it was like a sniper who had been aiming for a long time and finally pulled the trigger.

Excellent! The catheter passed smoothly through the stenosis without touching the wall of the tube, and then went a full twenty centimeters before Yang Ping let go.

Everyone put down their hearts when they mentioned their throats.

The oxygen saturation on the monitor, slowly rising, 90, 92, 95, 99--

It worked! Director Han suppressed his voice.

With the assistance of this demon lung, Mr. Ning has no problem surviving for a few days, and if he is lucky, he can survive dozens of days.
