Chapter 1743： I don’t understand you.

"The calculation of the inferior vena cava inhalation rate: maxdmindmaxd100." Zheng Ren sees Zhang's face stunned, and directly explained.

"Put the probe under the sword to the right, the scanning plane is parallel to the inferior vena cava, and the image shows the right atrium, inferior vena cava, and hepatic vein.

In the normal state, the inferior vena cava showed a significant collapse with deep inhalation, and the diameter of the inferior vena cava was 2.1 cm and the inspiratory collapse rate was > 50, which is 3 mmhg.

When the right atrial pressure is increased, the diameter can be >2.1 cm, and the inspiratory collapse rate is 50, that is, 15 mmhg. ”

Zheng Ren is like a Darling machine gun. After a sigh of relief, he does not give everyone a time to think. He said: "The diameter of the inferior vena cava is 2.4cm, and the inspiratory collapse rate is 50. It is obvious that it can be a pulmonary embolism."

"The fifth point, the tricuspid regurgitation speed increases, according to the simplified bernoulli equation..." said, Zheng Renton paused, seeing President Zhang looked blank and immediately sighed.

"You are not practicing medicine, you may not understand it. You only need to know that it is based on the bernoulli equation. In the case of tricuspid regurgitation, the embolus exists and it is very large."

President Zhang almost went to marry.

What is Laozi not practicing medicine? The principal of the Tang Dynasty Medical University, is there such a loss for you? !

But in my heart, I didn’t dare to say it. President Zhang did not expect that the anatomically skilled Zheng Boss talked about the theory, but also a set.

He was dissatisfied and looked up at Sun Chao and wanted to find Austrian aid.

If Director Sun Chao can also say that one, two, three, four, and five, to dispel Zheng’s arrogance, how good it should be. Starting

However, what President Zhang saw was... the face of Sun Chao, who was awkward.

Echocardiography, Sun Chao has an understanding, but it will never be so deep. What formula, what equation, is this what to say when looking at echocardiographic images? !

Sun Chao knows that President Zhang looks at himself, but he can... he didn’t understand it!

He can only pretend that he didn't see Zhang's gaze, his eyes were sloppy, and he looked at Zheng Ren.

A few days ago, the director of the Department of Cardiothoracic Surgery, wasn’t he like himself? People say nothing to understand, how to fight?

This is not a battle at all, but a unilateral killing!

"Sixth point, the anterior blood flow spectrum of the pulmonary artery shows a notch in the middle of the contraction, accompanied by a marked decrease in blood flow velocity, a shortened blood flow acceleration time, and a right ventricular ejection phase, which is usually referred to as the shortening of the rpep phase and act and right. Room ejection time ratio is reduced, etc., which is the standard of our diagnosis of "finger boxing." New 81 Chinese network update fastest computer: https://

Not finished yet...

After one two three four five five, there are still six!

Everyone is numb.

There is no echo of the heart of the scene, Zheng boss said, everyone feels plausible. However, if you want to argue, you can't get strong evidence.

What a special thing!

Director Sun Chao is bitter.

However, everything is not over.

"The seventh point, thrombosis is the most typical feature of thrombotic pulmonary embolism.

Thrombosis in the right or right ventricle can vary in shape, while in the pulmonary artery it often manifests as a large thrombus that extends from the trunk to one or both branches of the pulmonary artery.

The main pulmonary artery trunk thrombus is easy to show, and the left pulmonary artery is short, and the thrombus is not easy to display. In addition, it is necessary to distinguish the thrombus from the right heart system tumor! ”

"This patient's right pulmonary artery trunk thrombus is not very clear because of gas interference. But we can roughly estimate its length to be at least 10cm."

Zheng Ren said quickly.

"The thrombus is visible in the trunk of the right pulmonary artery and a small part in the right ventricle."

Having said that, he looked up and glanced at the principal, "There is a differential diagnosis of thrombosis and cardiac tumors, because we have limited time, we will not talk about it here."

President Zhang felt great contempt.

He thinks that Zheng’s subtext is that Lao Tzu said it, and you can’t understand it, so I won’t say it. It’s meaningless to say so much with your firewood, it’s totally meaningless.

As a mosaic, Sun Chao was directly ignored by Zheng Ren.

Really... really special!

Sun Chao secretly confessed himself.

"The eighth, abnormal compartmental movement..."

"Ninth, the foramen ovale reopens..."

However, Zheng’s words are not over yet.

After talking about the blood clot, Zheng Ren continued to say the eighth and ninth points.

After that, he put the list on his desk, his finger on the reader, and creaked.

"The diagnosis has been relatively clear, pulmonary embolism, thrombus blocked the right pulmonary artery trunk. Judging from echocardiography, the thrombus is very long, at least 10cm. This is one of the taboos for interventional thrombectomy!"

"And the patient's condition is urgent. If I have time, I can use 2 hours to get the bolt successfully. But now... I estimate that the patient's survival time is only about 1 hour. If you take the plug, or do other tests, the patient will die. ”

"Principal Zhang, signed!" Zheng Ren frowned, said in a commanding tone.

Time is urgent, what is drizzle, what respects old comrades, is a special nonsense.

President Zhang stunned.

Is this a forced palace? Is time really so urgent?

"Boss, the patient's oxygen saturation is 75! I first sent the operating room, and the surgery is ready to begin." Su Yun pushed the patient all the way, and when he passed the office, he snorted.

"Go." Zheng Ren took out a white a4 paper put it in front of President Zhang, said: "Principal Zhang, no time, the risk of surgery is great, the patient may not come to the operating table There are at least 40 sex."

"..." President Zhang shuddered.

It’s not just him, the directors of the vascular surgery around the country who are busy around, have shuddered.

But two chills mean different meanings.

President Zhang is because the students have 40 possibilities, but the other directors feel that the young man has 60 grasps to do the surgery!

This is a highly difficult surgery in the cloud. According to him, the patient will die within an hour.

Can an extracorporeal circulation be established in 1 hour?

He even said that he has 60 grasp?

10cm pulmonary embolism, cut the heart, cut the pulmonary artery, remove the thrombus...

Impossible, that is absolutely impossible!

In the subconscious, many directors did not question the diagnosis, but put all the mistrust into the success rate of the surgery.

It can't be so high!

"Agree with the operation, please sign it on this, there is no time to do other pre-operative explanation." Zheng Rendao: "I will write this paragraph after surgery."

"If you can't take care of it..." Zheng Ren said, looking at Ringer.

"Zheng boss, you can rest assured that the medical office is to **** the clinic. President Zhang can't make up his mind, and the medical department approves the surgery!" Linger said, not hesitating to say aloud.
