Start as an Emergency Physician

The needle insertion and needle distance must be carefully controlled, otherwise it is easy to cause problems, which may lead to additional damage to the suture and even leakage in severe cases.

The latter is something that Zhao Qiang needs to avoid at this stage, and once it leaks, I am afraid that his condition will worsen.

Zhou Yuan performed continuous sutures, and in order to avoid the shrinkage of the ring and the curling of the braided leaf, he added a small spacer to the base surface of the valve ring to assist in the suture.

"Small round knives. "

"Scissors. "

Zhang Ling immediately handed over the surgical instruments, and Zhou Yuan practiced to make perfect, alternately using Lianzhong instruments to remove part of the calcified basal surface.

"Gauze. "

The cardiac surgeon knew what Zhou Yuan meant, and the gauze was filled at the aortic valve orifice to prevent the removed calcium plaque from falling into the left ventricle.

Lu Chenxi didn't wait for Zhou Yuan's instructions, and took a small suction device to make the coronary artery opening for continuous suction, attracting some small changes into it to prevent it from falling into the body from the coronary artery.

Once calcium plaque appears in the blood vessels in the body, coronary artery blockage will occur after surgery, and there is only one consequence of blockage - myocardial infarction.

"Prepare saline. "

When he was about to complete the removal of calcium spots, Zhou Yuan said.

The role of saline is to flush the basal surface and prevent the appearance of calcium plaque residue.

A few minutes later, Zhou Yuan successfully removed the diseased aortic valve.

"Valve tester. "

The artificial valve needs to be suitable for the patient's body, and the diameter of the annulus must be measured to select the artificial valve, and in general, the valve with the largest diameter will be configured as much as possible, which is conducive to reducing the transvalvular pressure difference and improving cardiac function.

Of course, a little larger diameter than the annulus is sufficient, but if the artificial valve is too large, it is especially difficult to operate when the valve is sent to the ring, that is, when the valve is fixed. In addition, when the valve is forcefully delivered, it may cause tears in the intima of the Zhu artery and the incision of the aorta.

"Twenty-one mechanical flap. Zhou Yuan put down the valve tester and said.

He Jianyi immediately put the prepared twenty-one valves on the valve holder and handed them to Zhou Yuan.

The annular of the mechanical valve is short cylindrical, and Zhou Yuan finally decided to start from the lower edge of the annular and exit the needle from the middle and upper part of the suture ring.

If the needle exits from the upper edge of the annulus, the knotted suture stump may remain so long that it becomes embedded between the annulus and the valve body, resulting in acute valvular dysfunction.

All that was left in the room was the sound of the instruments dripping.

The only good news is that Zhao Qiang's heartbeat is still beating on its own, and his vital signs have stabilized.

Even Zhou Yuan couldn't be sure if he could save Zhao Qiang - his perfect-level CPR could only guarantee the patient's life in the case of a simple cardiac arrest, but now a major operation is still underway!

For example, Zhou Yuan's perfect-level CPR is a particularly good quality pump, and even a hot air balloon can be used to beat you up, but when you pump up, the other side is burning the balloon with fire, can this not burst?

Therefore, Zhou Yuan is actually gambling!

The only thing he can be sure of is that there is no mistake in his operation, all the doctors, including him, have done their best, and if they can't be rescued in the end, he has nothing to say.

......

Outside the ward, Li Li and the others sat in the corridor, leaning against the wall, their eyes blank.

Zhao Qiang's mother stood up, patted her buttocks, walked to Li Li's side and helped her up, and said, "Xiaoli, get up, you can't be wronged now, you still have a child in your belly!"

Several other elderly people also looked over, Li Li's mother looked around, there were no chairs outside the ward, and the nearest bench was more than ten meters away from Zhao Qiang's ward.

She knew that Li Li would never run over there to sit at this time, although everyone knew that it was useless to stay outside the ward, but at least she could feel at ease here.

No matter what the result is, even if it is a corpse that comes out, they want to see Zhao Qiang as soon as possible...

"Daughter, get up, otherwise Xiaoqiang will wake up and know that you have cried the child in your belly, what should I do?"

Li Li was about to cry, but when she heard this, she immediately held back her tears and stood up. "Then I'll just stand here and wait for him!"

The family knew that Li Li's personality was very stubborn, so they opened their mouths, but they didn't speak after all.

"Wife, go buy a little chair for your daughter. Li Li's father said in a deep voice.

After a while, Li Li's mother came back with five extra chairs in her hand, "It was given to us by the nurse in the emergency department." "

Li Li's father nodded silently and looked at Zhao Qiang's father.

At this moment, the two old men who had already handed over the family responsibilities to Zhao Qiang took on their responsibilities again. Zhao Qiang fell, and the rest were women, and the two of them had to prop up this family at this time!

The two old men sighed very tacitly, touched their pockets, and took out a pack of cigarettes from inside, and just put it in their mouths to light it, when they suddenly remembered that this was a hospital.

"You guys stay here, let's go outside. Li Li's father said.

Zhao Qiang's father also stood up.

Standing at the door of the hospital, the two were silent, smoking cigarettes one by one.

"Lao Li, if Xiaoqiang is really gone, let's beat the child. Zhao Qiang's father flicked the cigarette ash, and his eyes were cloudy.

Li Li's father, who was smoking, suddenly paused, and the cigarette was directly inhaled into his nose. He coughed violently a few times, and after a few moments, he closed his mouth, and then caught the liquid in his mouth with a tissue, and the moment he threw it into the trash can, he could see that the white tissue was already red.

". Li Li's father scolded, "What money do you give for the abortion? Lao Tzu has no private money at all, so he can't get a beating." Don't fight. "

Zhao Qiang's father stared at the trash can, took several puffs of cigarette, and then looked at Li Li's father with a somewhat complicated look, and was about to speak, but was interrupted by the latter.

Li Li's father: "Don't let Lao Tzu quit smoking. I've been smoking for more than 50 years, and after just one sip, I quit and died. "

Zhao Qiang's father's words were blocked, he was silent for a moment, and said again: "Beat the child." "

His expression was serious.

Zhao Qiang's father is just a farmer, if you judge it according to today's values, this is a person who has no interest, planted some crops when he was young, married a daughter-in-law, and people are also tendons, at that time, he was determined to let Zhao Qiang go to school, he worked hard like a cow in this life, never rested, and finally cultivated Zhao Qiang.

He doesn't have any big reason, but there is a sentence that has always been in his heart: no matter how hard it is, you can't drag others down.

If Zhao Qiang died, why drag Li Li's family, who was born in the city, into the water?
