The next morning, Zheng Ren got up with his normal biological clock. After washing, he received a call from Yan Changshen.

Yan Changsen said he was very polite, but he didn't have much nonsense. I talked to Zheng Ren about the situation at home. Seeing that Zheng Ren was very interested in surgery, I made an appointment to pick him up in the operating room and hung up.

But then Zheng Ren received a call from Christian, which surprised him.

After a few perfunctory words, Zheng Ren went downstairs for dinner. He was still more interested in today's operation.

"Su Yun, ask Kerry what he wants from me." Zheng Renhe is carrying the buffet plate to get breakfast, said Su Yun.

"Hmm? That's for you?" Su Yun was surprised. "What did he say?"

"Didn't say anything, just asked me where I was and what time I left today." Zheng Ren was a little helpless. "Tonight, if master Yan hasn't heard from him, he will go. There will be an operation tomorrow."

"What's your hurry?" Su Yun said contemptuously, "you don't go on stage when you go back. Sit down and watch Lao Gao do surgery. Are you tired of it?"

Zheng Ren smiled.

Lao Gao's level has improved rapidly. Now he rarely says what Lao Gao should do. He is preparing to let Lin Yuan take over the operator or Gu Xiaoran have a try.

It's really easy to have Lao Gao here. Zheng Ren is very happy to see the growth and harvest.

"Kerry, this product won't have anything to do with what happened yesterday." Su Yun said to himself while eating breakfast.

"Probably not." Zheng Ren said, "have you contacted Kerry recently?"

"Are you sure? You're going to take little stone to Europe once. You can't contact all the bodies of little stone, so you don't have to run back later." Su Yun said: "Kerry has provided a technology. Boss, do you have a spectrum about old Roche?"

Zheng Ren shook his head.

"I sent a few wechat messages to brother Yan. He seems to be busy all the time." Su Yun looked up at the person sent by Yan Changsen standing outside the cafeteria and said, "don't worry. Come out... If you do this again, you'll bring little Iraqis with you on your next business trip."

"It's not that serious." Zheng Ren smiled, "I just feel a little free here. I don't know what to do."

"It's said to open at 8:30 in the morning. It's almost time. You have to start after eating." Su Yun said, "the cardiothoracic surgery of Tiannan Medical University has strong cardiothoracic strength. I'll see someone else's surgery."

Zheng Ren knows what Su Yun means.

Even if you don't stand on the stage and look at it, it's also a more interesting thing. At least... It's more interesting than the operation done yesterday.

After hastily eating breakfast, I saw director Qiu standing in the lobby of the hotel waiting.

"Director Qiu, why are you here so early?" Su Yun walked up and asked politely.

"Miss Su, I'll pick you up and boss Zheng." Director Qiu asked with a smile, "how was your rest yesterday?"

"Director Qiu, you are so polite. You don't dare to call the teacher in front of you. Just call me Xiao su." Su Yun was polite.

"Yes, yes. How was your sleep? Are you used to it?"

"OK." Su Yun said, "Yangcheng is much wetter than the imperial capital. There are three humidifiers at home. You have to wake up in the middle of the night. It's good and the air humidity is high."

"That's good, that's good."

"Director Qiu, it's very kind of you. We thought we would take brother Yan's car directly to the hospital and contact you again."

"How can that!" Director Qiu dared not even stare jokingly. He politely lowered his attitude and said, "you are now giants in the medical field. At this age, you are bound to rule the academic field for at least thirty or fifty years in the future. When we came to Yangcheng, we met by chance, and I dare not put on the airs of elder brother."

"That's very kind. Let's go." Zheng Ren said, "Su Yun, let's take director Qiu's car."

Su Yun understood and explained to Yan Changshen's people, then walked out of the hotel with Zheng Ren and got on director Qiu's car.

Director Qiu felt that his car could not be washed for several months. Boss Zheng had sat down, which was equivalent to running out. Do you want to seal it up and touch it twice a day for good luck? It is said that boss Zheng has good luck. I don't know whether the legend is true or not.

"Director Qiu, how are you preparing for this operation?" Zheng Ren asked.

"Surgery?" Director Qiu was stunned for a moment. He thought that boss Zheng was really focused on business. He didn't chat in the car and directly asked for the operation.

"The patient's condition is more serious. The heart side is also consulted by the whole hospital for many times. Finally, I communicated with the patient's family members, prepared to stand down, and dared to go up only after reaching a consensus." Director Qiu said, "I'm afraid there's something else to delay. I don't rush to do it during the weekend. If there's a problem, everyone has time and enough people to rescue."

Huge left heart hypertrophy, Zheng Ren has done it by means of interventional surgery. But this patient has mitral insufficiency and huge left atrium. Director Qiu said yesterday that Zheng Ren especially wanted to see how Tiannan doctors were going to do this difficult operation.

"Echocardiography, do you remember?" Zheng Ren asked.

"The anterior posterior diameter of the left atrium in patients undergoing surgery is 88mm, the left and right diameter and the upper and lower diameter are 126mm and 171 mm." Director Qiu is proficient in business. He said directly while lighting a fire and starting the vehicle.

The maximum anterior posterior diameter of the left atrium in normal adults is 23 ~ 38mm, and the maximum upper and lower diameter is 31 ~ 68mm. Director Qiu said the data are really rare.

"I've never done such a big left atrium." Su Yun said, "director Qiu, your data will come soon. Has the whole hospital consulted at least ten times?"

"Isn't it?" Director Qiu drove on the road and said, "the patient's medical office asked me to go to the whole hospital for consultation and go in person. The operation is very difficult and the anesthesia is also very difficult."

"Well, anesthesia is very important for patients with cardiac insufficiency." Zheng Ren smiled and said.

"Boss Zheng, when I had dinner with my friends some time ago, I heard that you have a full-time anesthesiologist in your medical team. Your level is very high." Director Qiu asked.

"Well, Lao he's level is very high. Some operations, secondary valve replacement, and the recently made pacemaker electrode head is broken at the right atrial appendage. He is anesthetized. Lao he is..."

"Boss, these two operations are not heavy. Lao he took Da Chu and Xiao Chu to perform conjoined baby separation surgery, which reflected the level." Su yundao.

"Conjoined baby?"

"Well, the heart is conjoined. Ask the anesthesiologist to reduce the non concentricity rate to a level. Su Yun and I will separate the operation." Zheng Ren said: "Lao he's very high level and commands in the middle."

"..." director Qiu listened with longing.

Heart conjoined baby, boss Zheng can do it! He was knowledgeable, so he only mentioned the conjoined heart, and his head immediately became big.

There is such a powerful anesthesiologist in boss Zheng's medical group!

"Patients with huge left atrium are easy to form left atrial thrombosis due to slow blood flow. Anesthesia should follow the principles of perfect analgesia, light interference to circulation, no increase in myocardial oxygen consumption and no impact on myocardial work. The specific operation is not easy." Zheng Ren said with a smile.
