Start as an Emergency Physician

Everyone has a trance-like feeling, here everyone is more like they came to watch the performance, occasionally they help pass the instrument or something, and the rest of the time they just need to be responsible for shouting 666 next to them.

"Prepare the surgical instruments. Zhou Yuan said as he pressed.

Lu Chenxi was stunned: "Just here for the operation?!"

Zhou Yuan nodded: "There is no way, I can only operate on the spot." "

Zhang Ling now almost regarded Zhou Yuan's words as a holy decree, and ran out directly to prepare the equipment.

Outside the ward, Li Li and others rushed to the hospital after receiving the news, and were waiting anxiously outside at the moment, and as soon as they saw Zhang Ling coming out, they immediately surrounded him.

"Nurse, how's it going?"

"What's wrong with my son!"

Zhang Ling didn't have time to answer, "I need to prepare the surgical equipment immediately, and Zhao Qiang must perform the operation immediately!"

When Li Li and the others heard this, they immediately got out of the way, no matter how curious they were, they couldn't stop Zhao Qiang's life-saving way!

When he came back, Zhang Ling found that Li Li and the others were still waiting outside the operating room with a worried face, a little unbearable, and said softly before entering the door: "Don't worry, it was the best doctor in our hospital who operated on Zhao Qiang, does Dr. Zhou Yuan know... He'll be able to get people back!"

I don't know why, Zhang Ling has such self-confidence!

After saying this, Zhang Ling didn't stay any longer, entered the ward directly, and closed the door again.

The shadowless lamp that was temporarily sent over had been set up, and Zhang Ling put all the surgical instruments she needed on the surgical tray, and she also participated in the previous discussion of the surgical plan, so she was also very clear about what instruments she needed.

Everything was ready, Zhou Yuan continued to press, the value on the monitor was already much better, and Zhao Qiang's heart gradually resumed beating, although it was still slight, but at least it could barely maintain the patient's life.

The surgery can only be performed in this case.

He Jianyi and the deputy director of cardiac surgery were shocked, both of them had done cardiopulmonary resuscitation for the patient's heart malformation, so they knew that Zhao Qiang's current situation was particularly bad, and it was extremely difficult to save him, but Zhou Yuan actually did it, and he recovered to the point where he could perform surgery!

In the eyes of the two, this is almost impossible!

"Endotracheal intubation and intravenous combination anesthesia. "

Zhou Yuan continued to press the patient's chest.

Now you need to pay extra attention, because the lungs are nearby, you must be careful not to damage the lungs, otherwise the anesthetic drug may escape through the air bubbles in the lungs, and the damage to the lungs will endanger Zhao Qiang's life.

After completing the anesthesia, He Jianyi and others assisted Zhou Yuan to adjust Zhao Qiang's position, and finally adopted a supine position, with the chest and back being raised, which was conducive to the exposure of the surgical field.

"Let's get ready for surgery. Zhou Yuan marked with a marker again on both sides of the patient's incision.

The previous chest incision was for intrathoracic compression, and only two hands needed to be accommodated, so the incision was relatively small, but now the surgeon is required to perform the operation of instruments in the chest cavity, and a large incision is definitely needed.

The position of the opening was still chest Zhengzhong, and Zhou Yuan used a scalpel to enlarge the incision along the marker mark.

The cardiac surgeon and Lu Chenxi prepared the extracorporeal bypass device, and the two of them did a lot of this step, which was considered to be very familiar, and when Zhou Yuanyi completed the dissection of the chest incision, the two immediately installed the cardiopulmonary bypass device.

This time, the aortic cannula was selected, and the extracorporeal bypass tube passed through the right atrial appendage and right atrium, and some of the upper and lower vena cava were intubated from the upper and lower vena cava, and the whole process of cardiopulmonary bypass maintained severe hypothermia and local hypothermia of myocardium.

This is to minimize the loss of energy and so on while ensuring the normal life activities of the patient.

"Cardiopulmonary bypass complete. "

"Ready. "

Lu Chenxi and the deputy director of cardiac surgery said one after another.

Zhou Yuan nodded, "Start myocardial protection." "

This step is crucial during surgery.

Due to the sudden onset of the patient's condition, the patient's family and the doctor did not have enough time to prepare, let alone the small details before the operation, and even the current operation was rushed out, so Zhao Qiang's heart muscle could only be protected as much as possible during the operation to reduce the surgical damage.

The first dose of cardioaponsis was injected into Zhao Qiang's body by Lu Chenxi from the root of the aorta, a total of 1,000 milliliters, almost comparable to a large bottle of Coke.

After completing the myocardial protection, Zhou Yuan did not stop, and directly picked up the scalpel to make an incision on the aorta.

There are generally three types of incisions in the aorta, transverse incisions, hockey oblique incisions, and spiral incisions.

The transverse incision is more conventional, that is, the anterior and lateral walls of the ascending aorta are incised at 1.5~2.0 cm above the opening of the right coronary artery, mainly for cases with thick aorta, in which case the patient's incision is better exposed. The hockey-shaped oblique incision is an incision from the left anterior side about 2 cm away from the aortic root to the right and 1.0~1.2 cm above the midpoint of the non-crowned valve leaflet, which is suitable for patients with thin aortic roots.

The final spiral incision, with the upper end of the opening close to the main pulmonary artery and its lower end into the non-crowned valve, incorporates the base of the mitral valve between the non-crowned and the left coronary valve. This incision is suitable for patients with too small an aortic annulus.

Zhao Qiang's aortic valve insufficiency does not have much particularity, but because he has suffered from heart disease since he was a child, his aortic root is relatively weak, so he can only choose a hockey-shaped oblique incision.

Eight minutes later, Zhou Yuan completed the incision of the aorta, and the next step was to cut the valve and suture the ring.

Zhou Yuan carefully enlarged the aortic incision to reveal the aortic valve.

Zhao Qiang has no heart at the moment, has lost the effect of blood pressure, the entire blood vessel has been deflated, and it took a lot of effort to make an incision and find the aortic valve.

Zhou Yuan carefully opened the blood vessels around the valve and probed the lesion of the aortic valve.

"There was no fibrosis and no sclerosis. Zhou Yuan breathed a sigh of relief.

That's probably the only good news.

Of course, this is meaningless good news, even if fibrosis and sclerosis occur, Zhao Qiang still has to replace the valve in the end, and now the situation of the aortic valve is not so important.

"Medium curved pliers. Zhou Yuandao.

He took the medial forceps, clamped the middle of the valve leaflet, and pulled the aortic lumen on either side, like that, and removed the left crown valve. After the excision, Zhou Yuan took the needle forceps and began to suture along the junction to the middle of the sinus, the span of each needle was precisely controlled at three millimeters, and the needle distance was controlled between two millimeters.
