Start From Emergency Doctor

Chapter 396

Needle entry and needle length must be controlled very delicately, otherwise it is easy to cause problems. If it is light, it may cause additional damage to the suture, and if it is severe, it may even leak.

The latter is what Zhao Qiang needs to avoid at this stage. Once the fluid leaks, his condition may worsen.

Zhou Yuan performed continuous sutures. In order to avoid shrinking loops and braided leaf curling, he added a small pad on the base of the annulus to assist in the suture.

“Small round knife.”

“scissors.”

Zhang Ling immediately handed over the surgical instruments. Zhou Yuan used the Lianzhong instruments alternately to remove part of the basal surface where calcification occurred.

“gauze.”

The heart surgeon knows what Zhou Yuan meant. The gauze filling at the aortic valve orifice is to prevent the excised calcium plaque from falling into the left ventricle.

Without waiting for Zhou Yuan’s instructions, Lu Chenxi took a small suction device to open the coronary artery for continuous suction, attracting some small changes into the body to prevent it from falling into the body from the coronary artery.

Once calcium plaques appear in the blood vessels in the body 26, the coronary artery will be blocked after the operation, and there is only one consequence of the blockage-myocardial infarction.

“Prepare saline.”

When the plaque removal was about to be completed, Zhou Yuan said.

The role of physiological saline is to wash the basal surface and prevent calcium spots from remaining.

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

“Velometr.”

The selected artificial valve needs to be suitable for the patient’s body. The diameter of the valve annulus must be measured to select the artificial valve. Generally, a valve with as large a caliber as possible will be configured, which will help reduce the transvalvular pressure difference and improve heart function.

Of course, it should be slightly larger than the caliber of the valve annulus. If the artificial valve is too large, it is particularly difficult to perform valve delivery and seat ring, that is, to perform valve fixation. Moreover, when the valve is delivered forcefully, it may cause tearing of the intima of the Zhu artery and the aortic incision.

“No. 21 mechanical lobe.” Zhou Yuan put down the lobe detector and said.

He Jianyi immediately installed the prepared twenty-one valve on the valve holder and handed it to Zhou Yuan.

The annulus of the mechanical valve is short and cylindrical, Zhou Yuan finally decided to start the needle insertion from the lower edge of the annulus and eject the needle from the middle and upper part of the suture ring.(Read more @ wuxiax.com)

If the needle is ejected from the upper edge of the annulus, the knotted suture stump may be left too long, so as to be embedded between the annulus and the valve body, and finally cause acute valve dysfunction.

Only the sound of instruments remained in the ward.

The only good news is that Zhao Qiang’s heartbeat is still beating spontaneously, and his vital signs have stabilized.

Even Zhou Yuan can’t be sure whether Zhao Qiang can be rescued. His perfect CPR can only guarantee the patient’s life in the case of a simple cardiac arrest, but he is still undergoing a major operation. what!

For example, Zhou Yuan’s perfect CPR is a pump of very good quality. Even a hot air balloon can beat you up, but when pumping up, the other side is burning the balloon with fire. Can it not explode?

Therefore, Zhou Yuan is actually betting!

The only thing he can be sure of is that his operation did not make any mistakes. All the doctors, including him, have done their best. If they have not been able to rescue them in the end, he has nothing to say.

…

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

Zhao Qiang’s mother stood up, patted her butt, walked to Li Li’s side to help her up, and said: “Xiao Li, get up, you can’t be wronged now, you still have children in your stomach!”

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 go to sit there at this time. Although everyone knew that it was useless to stay outside the ward, at least she could feel at ease here.

Regardless of the result, even if it was a corpse, they wanted to see Zhao Qiang as soon as possible…

“Daughter, get up, otherwise Xiaoqiang wakes up and knows you broke the baby in your stomach, what should I do?”

Li Li was about to cry. Hearing these words, she immediately held back her tears and stood up. “Then I will stand here and wait for him!”

The family knew that Li Li’s character was very stubborn, so they opened their mouths, but did not speak after all.

“Wife, you go and buy a small chair for your daughter.” Li Li’s father said in a deep voice.

After a while, Li Li’s mother came back with five more chairs in her hand, “They were given to us by the nurse in the emergency department.”

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

At this moment, the two old men who had already handed over the responsibility of the family to Zhao Qiang took the responsibilities again. Zhao Qiang has fallen, and the rest are women. The two of them must support this family at this time!

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

“You are here to guard, 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.

“Old Li, if Xiaoqiang is really gone, kill the child.” Zhao Qiang’s father flicked the soot, his eyes cloudy.

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

“Fuck you?” Li Li’s father scolded, “Do you pay for the abortion? I don’t have any private money, so I can’t fight. Don’t fight.”

Zhao Qiang’s father stared at the trash can, took a few puffs of cigarettes, and then looked at Li Li’s father with some complicated eyes. Just as he was about to speak, he was interrupted by the latter.

Li Li’s father: “Don’t let Lao Tzu quit smoking. After smoking for more than 50 years, it’s just a bite. If you quit, you will die.”

Zhao Qiang’s father’s words were blocked, and he was silent for a moment, and then said again: “Stop the child.”

His expression is serious.

Zhao Qiang’s father is just a farmer. If judged according to current values, he is a worthless man. When he was young he planted some crops and married a daughter-in-law. He was also a stickler. At that time, he was determined to let Zhao Qiang go to school. He has worked hard all his life, never rested, and finally cultivated Zhao Qiang.

He doesn’t have much reason, but there is one sentence that he always remembers in his heart: No matter how hard it is, it can’t drag others down.

If Zhao Qiang is dead, why drag the Li Li family who was born in the city into the water? .
