Chapter 2563 It's Really Stuck (Leader Blowfly Adds 2)

"Is it Boss Xiao Zheng from 912?" Director Xu asked suspiciously.

"Yes." Zheng Ren nodded.

"Why are you here!" Director Xu was pleasantly surprised, and the unhappiness of asking him to reopen it to take a look before disappeared.

Seeing that Director Xu turned to leave the stage, Zheng Ren hurriedly said, "Director Xu, the operation is not over yet! Open it first and take a look."

"oh oh."

Director Xu didn't insist at all this time, his principles and positions flew into the sky along with his previous anger.

"Boss Zheng, I have admired you for a long time." Director Xu suppressed his excitement and said, "What are you doing to Director Qiu? He is an anesthetist."

"How are you talking?" Director Qiu said unhappily.

Zheng Ren saw that Director Xu started to twist the steel wire in reverse, and then glanced at the ECG waveform and radial artery pressure curve, and felt that there was enough time.

"You're welcome." He said lightly, and then said: "Don't withdraw the extracorporeal circulation first, prepare to establish it again immediately!"

The extracorporeal circulator has long been dumbfounded, the legendary Boss Zheng? ! For a full 6 hours, I didn't notice any difference.

No, it's a big deal not to close your chest. Director Xu and Director Qiu didn't notice any abnormalities on stage. They refused to close their chests at the last moment. What's the matter? Hold back and slap your face at the last moment?

No, no, the extracorporeal circulation specialist immediately shook off all the messy things in his mind. Boss Zheng said there was a problem, but if he opened it and saw that nothing was wrong, it would be like slapping himself in the face, right?

Seeing Director Xu's adoring face, Su Yun's hand that twisted the steel wire trembled a little, and thought it was funny, so he said, "Director Xu, keep your hands steady and hurry up."

"Oh, oh, don't worry." Director Xu meekly seemed to be a different person, no longer cold as ice, but responded like an intern.

"Boss Zheng, what's going on?" Director Qiu whispered in Zheng Ren's ear.

"The ECG oscillogram does not match the pressure curve of the radial artery, considering the mitral valve..."

After Zheng Rengang spoke half a sentence, the alarm of ECG monitoring suddenly sounded, and then the ventilator also started to use sharp alarms to remind people in the operating room of abnormal conditions.

"Hurry up! Prepare for extracorporeal circulation." Zheng Ren had already switched to the operator mode. In this room, he is the unique king!

Although I still don't know why, everyone in the operating room moved. Director Xu didn't have time to express his admiration to Boss Zheng and Su Yun, so he took the time to unscrew the wire.

At this time, the blood pressure drops sharply, and the peak value of the arterial waveform decreases and gradually becomes a straight line.

"Dopamine, speed up."

"Epinephrine, 1mg IV."

"Another shot of adrenaline!"

"Come on extracorporeal circulation, ready to re-establish."

"Open the chest faster! Open according to the replacement valve."

The order after order was issued, and the peaceful atmosphere in the operating room disappeared.

Director Qiu and the itinerant nurse hurried to work, their feet barely touched the ground, as if they were flying in the air.

I am most afraid of this kind of situation. Fortunately, Boss Zheng reminded me that otherwise it would take 10 minutes just to twist the wire. During this period of time, the patient's vital signs must be maintained by drugs. Judging by the blood pressure, the drugs can play a little role at the beginning, but they will soon be useless.

Booster drugs are difficult to maintain the patient's blood pressure, the average blood pressure is 20-30mmHg, and the heart rate also rises to 120-130 beats/min. This is not counted, the SpO2 waveform of the patient's left hand is consistent with the pressure waveform of the right radial artery, and it is also a straight line.

Needless to say, everyone present knows what a straight line means.

MD, what's going on!

After 20 seconds, the waveform recovered slightly. But before everyone's tense mood relaxed, a straight line appeared in the field of vision again.

This happened repeatedly, and the interval time became shorter and shorter, and the heart rate also rose to 120-150 beats/min. The blood flow of the radial artery pressure measuring tube was smooth, indicating that the radial artery pressure measuring tube was normal, and it was not a problem with the machine. But something really happened!

Director Xu opened the chest cavity as quickly as possible, and began to establish extracorporeal circulation. Because of Zheng Ren and Su Yun's previous reminders, this period of time was shortened to a certain extent.

"Aortic root pressure measurement!" Zheng Ren said in a deep voice.

Director Xu immediately began to measure the pressure of the patient's aortic root, which was the same as that of the radial artery... His sweat immediately came down again.

Boss Zheng didn't aim for nothing, but saw something unusual. What the hell is going wrong? ! Director Xu felt that his hands were cold, and all the movements in front of him became extremely slow, as if he had entered another world.

Not only is the pressure measurement of the aortic root consistent with the radial artery, the aortic root becomes soft, and the valve sound of the bioprosthesis also disappears. This all means one thing... Something happened to the valve replacement just now!

Extracorporeal circulation was established urgently, and the second turnaround.

Because there was a reminder in advance, the preparation time of the extracorporeal circulation machine did not delay the operation. When the heart is opened, the posterior chordae of the mitral valve rupture from the papillary muscle, causing the chordae to become lodged in the prosthetic valve.

It's really a card flap! Director Qiu and Director Xu watched the scene in front of them helplessly, feeling horrified in their hearts.

The free chordae were resected, and the original biological flap was still sutured continuously. It's not difficult to deal with it, at least for Director Xu. The final twist and difficulty lies in the cooperation between the surgeon and the anesthesiologist.

After observing an abnormal situation, whether the anesthesiologist knows it is the key to reminding the operator in time. Under the pressure of the operator's strong aura, not all anesthesiologists can stick to their own judgment, and perform a second thoracotomy early to detect abnormalities.

Mitral valve chordae rupture followed by flap jamming is an uncommon complication of valve replacement surgery.

This occurrence may have something to do with the patient's heart failure. Director Xu felt a little innocent. After the valve replacement, he observed carefully for a few minutes and saw that the mitral valve chordae did not seem to have a problem, so he continued to the next step.

Who would have thought that something would happen after the chest was closed.

What the hell! If it is said that doctors can't do this job, there are big pits everywhere, who knows which pit will be buried one day.

After emergency cutting of the mitral valve chord, the biological valve began to work again, and the alarm sound of the instrument disappeared.

The rest is routine operation, Director Xu looked up at Boss Zheng, and whispered, "Boss Zheng, thank you."

"You're welcome." Zheng Ren also heaved a sigh of relief. At the very beginning, he saw something vaguely wrong with the ECG oscillogram and radial artery pressure curve, and he entered the operating room of the system to confirm that something had happened.

But why is Su Yun so determined?

Zheng Ren glanced at Su Yun with some doubts.

"What do you think I'm doing?" Su Yun was recording the anesthesia order, and looked up at Zheng Ren as if he had sensed it.

"How do you judge?"

"There is a problem, but I'm not sure. Seeing how sure you are, I'm sure. It's such a simple thing." Su Yun said, "It's amazing that the wrong chest was opened again, and the operation was delayed for half an hour. We both went back in despair. gone."

Zheng Ren spread his hands.
