Start with an emergency physician

Lu Chenxi's face changed:"Aortic dissection aneurysm is a major operation. I have never done it. We can only ask Dean Fu to come over!"

Zhou Yuan calmly pressed Zhang Shan's chest and said:"Give him morphine and sedatives for pain immediately to relieve the patient's pain first, otherwise he will faint from the pain sooner or later!"

Then he looked at Lu Chenxi:"You have never done this operation, don't you know how to treat it?"

Lu Chenxi quickly replied:"The initial treatment goal is to control the systolic blood pressure at 100~120mmHg and the heart rate at 60~75 beats per minute!"

Zhou Yuan looked at the young nurse Yang Yu:"Immediately reduce myocardial contractility, slow down the left ventricular contraction rate and peripheral arterial pressure. Zhang Shan has high blood pressure, use intermittent intravenous administration of propranolol and intravenous drip of sodium nitroprusside to lower blood pressure to the clinical treatment index!"

Lu Chenxi felt something was wrong the more he listened, until he saw Zhou Yuan holding the bed and preparing to push it, and asked in panic:"What are you going to do!"

"The patient's aortic dissection aneurysm is nearly ten centimeters in diameter, and the vascular malformation is serious and worsening, and there is aortic valve insufficiency and hypertension. If he does not undergo surgery directly, he will die!"

Lu Chenxi said anxiously:"But I have never performed such a bad operation before!"

"Push it forward!"

Zhou Yuan did not continue to argue with Lu Chenxi, but turned to ask Yang Yu:"Is the operating room ready?"

Yang Yu nodded immediately:"Operating Room No. 1 has been vacated, and all the instruments are ready."

Zhou Yuan nodded,"Give me a hand, push it over!"

After that, he said to Lu Chenxi:"Start preoperative preparations immediately, don't think too much, I'm going to get the signature of the patient's family now."

Aortic dissecting aneurysm resection is an extremely complicated operation. Even if Zhou Yuan has master-level skills, it is impossible to complete it alone.

The time spent discussing with the family members was just enough for Lu Chenxi to adjust her state.

When she arrived at the waiting room, Zhang Shan's daughter had already cried red eyes. When she saw Zhou Yuan coming out, Zhang Shan's daughter immediately ran over.

When Zhou Yuan talked about aortic dissecting aneurysm, Zhang Shan's daughter was obviously stunned. She didn't understand

"Let's put it this way. The blood vessel wall is likened to a three-layer plywood. After the intima layer of the blood vessel ruptures, blood flows into the media, causing the outer membrane to become weak. Its greatest harm is that when blood pressure rises or the heart rate changes rapidly, the blood vessel is prone to rupture and bleeding, which can lead to death."

"And now, there is an aneurysm with a diameter of about ten centimeters in the aorta. Coupled with a series of complications, your father's condition is even more critical and he must undergo surgery as soon as possible!"

""Doctor, although I didn't understand, I believe you!"

Zhang Shan's daughter signed immediately after saying this.

Zhou Yuan was silent for a moment, stared at the informed consent form, and hurried to the operating room.

In the operating room, everything was ready.

Lu Chenxi also quickly adjusted her state and prepared for the operation.

At this time, Zhou Yuan took the scalpel and glanced at Lu Chenxi:"Stay aside."

This girl doesn't think she is the surgeon? Naive.

Zhou Yuan smiled and looked at the time:"The operation begins."

Lu Chenxi was shocked,"What are you doing! Now is not the time to joke! Human life is at stake!"

Zhou Yuan's face was calm:"It is precisely because human life is at stake that I can't let you go up"

"‘Is the trunk ready? Zhou Yuan asked.

Lu Chenxi wanted to stop the intern Zhou Yuan from making trouble, but the latter yelled,"If you make any more noise, I'll give you a shot of Valium," and then he calmed down.

"Believe me." Zhou Yuan's voice was full of confidence.

Lu Chenxi thought of Zhou Yuan's incredible suturing and hemostasis techniques, and suddenly a little hope emerged in her heart, and she said:"Instrument nurse, prepare the full-course support elephant trunk technique immediately."

Lu Chenxi's words also meant that from this moment on, Zhou Yuan became the surgeon in the operating room, and all orders were subject to Zhou Yuan.

"The"elephant trunk" technique is a surgical method for treating extensive aortic disease, which involves inserting an artificial blood vessel into the descending thoracic artery to replace the human blood vessels for blood supply and transfusion. This section of artificial blood vessel is called the elephant trunk.

Generally speaking, the true lumen of aortic dissection is often very narrow, making it difficult to insert an artificial blood vessel, and the soft elephant trunk tube will interfere with the blood supply of the branch arteries. When replacing the aortic arch, a supporting artificial blood vessel is often selected, which is what Lu Chenxi calls the full-course supporting elephant trunk technique.

Zhou Yuan quickly opened the chest cavity and made a median sternal incision. The aortic arch was cut open at the proximal end of the left subclavian artery. With the assistance of Lu Chenxi, a stent vessel about ten centimeters long and twenty-six millimeters in diameter was inserted into the true lumen of the descending aorta.

The next stage was the stage Zhou Yuan was best at.

He picked up the needle holder, repaired the proximal end of the artificial blood vessel, and sutured it continuously with the remaining descending aorta. After the anastomosis was completed, he reconstructed the anastomosis of the head, brachial plexus and proximal aorta on the artificial blood vessel in turn.

This again attracted the amazement of the young nurses in the operating room, and some of the beautiful young nurses looked at Zhou Yuan with a different look.
