Chapter 2565

"Is it boss Xiao Zheng of 912?" Director Xu asked suspiciously.

"Yes." Zheng Ren nodded.

"Why are you here!" Director Xu was surprised and happy. The unhappiness he had asked him to open it again disappeared.

Seeing that director Xu turned to step down, Zheng Ren hurriedly said, "director Xu, the operation is not finished! Open it first."

"Oh, oh."

This time, director Xu didn't insist at all. His principles and position took off with his previous anger.

"Boss Zheng, I've heard a lot." Director Xu repressed his excitement and said, "what's wrong with director Qiu? He's an anesthetist."

"How do you talk?" Director Qiu said unhappily.

Zheng Ren saw that director Xu began to twist the steel wire in reverse. He took another look at the waveform of ECG monitoring and the pressure curve of radial artery. He felt that time was enough.

"You're welcome." He said faintly, and then said, "don't withdraw cardiopulmonary bypass, and prepare to establish it again immediately!"

Cardiopulmonary bypass Division has long been silly, the legendary boss Zheng?! For six hours, I didn't see any difference.

No, don't close your chest. It's a big deal. Director Xu and director Qiu didn't see anything unusual on the stage. They didn't let them close their breasts at the last minute. What's the matter? Bear it and hit the face at the last minute?

No, no, the cardiopulmonary bypass division immediately threw away the mess in his mind. Boss Zheng said there was a problem. If you open it and see that there is nothing wrong, it will become beating yourself in the face.

Su Yun saw that director Xu's face was worshipped and his hands wringing the steel wire trembled slightly. He felt funny. He said, "director Xu, keep your hands steady and hurry up."

"Oh, oh, don't worry." Director Xu's meekness is like a changed person, no longer cold as an iceberg, but like an intern.

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

"The ECG wave does not coincide with the radial artery pressure curve wave, considering the mitral valve..."

Zheng Rengang said half a sentence. Suddenly, the alarm of ECG monitoring sounded, and then the ventilator began to use a sharp alarm to remind people of abnormalities in the operation room.

"Hold on! Prepare for cardiopulmonary bypass." Zheng Renzao has switched to the operator mode. In this room, he is the unique king!

Although I still don't know why, everyone in the operation moved. Director Xu had no time to express his admiration with boss Zheng and Su Yun, so he took the time to unscrew the steel wire.

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

"Dopamine, speed up."

"Adrenaline, 1mg intravenously."

"One more adrenaline!"

"Extracorporeal circulation is stepping up and ready to be re established."

"Chest opening speed point! Open according to the valve replacement."

One instruction after another, the quiet atmosphere in the operating room disappeared.

Director Qiu and the itinerant nurses were busy, their feet hardly touched the ground and flew in the air.

I'm most afraid of this situation. Fortunately, boss Zheng reminded me that it would take 10 minutes to screw the steel wire alone. During this period of time, we rely on drugs to maintain the patient's vital signs. Depending on the blood pressure, drugs can also play a little role at the beginning, but they will soon be useless.

Pressor drugs are difficult to maintain the patient's blood pressure, the average pressure is 20 ~ 30mmhg, and the heart rate also rises to 120 ~ 130 beats / min. This does not count. The left SpO2 waveform of the patient is consistent with the pressure waveform of the right radial artery, which is also a straight line.

Straight line, what does it mean? Needless to say, everyone here knows.

MD, what happened!

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

This situation occurs repeatedly, and the interval is getting shorter and shorter. The heart rate also rises to 120 ~ 150 beats / min. the blood circulation of the pressure measuring tube of the radial artery is smooth, indicating that the pressure measuring tube of the radial artery is normal, which is not a problem of the machine, but something really happened!

Director Xu opened his chest as quickly as possible and began to establish cardiopulmonary bypass. Because of Zheng Renhe and Su Yun's previous reminder, this period of time has been shortened to a certain extent.

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

Director Xu immediately began to measure the pressure at the root of the patient's aorta, just like the radial artery... His sweat came down again soon.

Boss Zheng didn't aim at nothing, but saw the abnormality. What's wrong with this?! Director Xu felt that his hands were cold, and his movements in front of him became extremely slow. The whole person seemed to have entered another world.

Not only is the pressure measurement at the aortic root consistent with that of the radial artery, the aortic root softens and the valve sound of the biological valve disappears, which means one thing... Something really happened at the position where the valve was just changed!

Emergency establishment of cardiopulmonary bypass and secondary transfer.

Because of the warning in advance, the preparation time of the cardiopulmonary bypass machine did not delay the operation. When the heart was opened, the tendon of the posterior mitral valve ruptured from the * * muscle, resulting in the insertion of the tendon into the artificial valve and valve clamping.

Really, it's kappa! Director Qiu and director Xu looked at the scene helplessly, and their hearts were filled with horror.

Free chordae tendineae were resected and sutured continuously with proto biological flap. There is nothing difficult to deal with, at least for director Xu. The final difficulty lies in the cooperation between the operator and the anesthesiologist.

After observing abnormal conditions, whether the anesthesiologist has a number in mind is the key to remind the operator in time. Under the pressure of the strong gas field of the operator, not all anesthesiologists can adhere to their own judgment, and open the chest twice as soon as possible to detect abnormalities.

The rupture of mitral chordae tendineae complicated with valve clamping is an uncommon complication of valve replacement.

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 it carefully for a few minutes and saw that there was no problem with the mitral tendinous cord, so he continued the next operation.

Who would have thought that something happened after closing the chest.

Really special! The doctor can't do this job. There are big pits everywhere. Who knows which pit will be buried one day.

After the mitral tendinous cord was cut off urgently, 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 breathed a sigh. At first, he saw that there was something wrong with the ECG and radial artery pressure curve. He entered the system operating room to determine that there was an accident.

But why is Su Yun so firm?

Zheng Ren glanced at Su Yun with some doubts.

"What are you looking at me for?" Su Yun was recording the anesthesia list and looked up at Zheng Ren like an induction.

"How did you decide?"

"There's a problem, but I'm not sure. If you're so sure, I'm sure. What a simple thing." Su Yun said, "great, it's wrong to reopen the chest. We'll delay the operation for half an hour. We'll just go back dejected."

Zheng Ren let go.
