Chapter 557 Life with an Artificial Heart

Director Li explained clearly, and the movements in his hands were also carried out in an orderly manner.

"Because there are coronary arteries and aortas in the myocardium, these blood vessels need to be ligated during the operation."

"The aorta is then cut and the aortic valve is cut off, and the mitral and tricuspid valves are removed at the same time, and the connecting sleeve is put in the mitral and tricuspid valves, and it is sutured with the heart, and then water is injected with a water injector, Check for penetration at the suture site."

"The pulmonary artery is sutured with the artificial pulmonary artery, and the aorta is sutured with the artificial aorta. The artificial artery is about 3 centimeters thick."

"Fill the injector with water to make sure there are no leaks from the suture."

"An artificial pericardium is placed around the artificial heart to reduce the stimulation of the artificial heart to the surrounding tissue and reduce the chance of infection."

"The left atrium is then connected to the artificial aorta using a left ventricular assist device, and the right ventricle is connected to the artificial pulmonary artery using a right ventricular assist device."

"The air in all the cavities of the heart must be exhausted to prevent gas embolism."

"Finally, let the artificial heart start to work, and then remove the artificial heart-lung machine, stop the bleeding, close the sternum, and suture the incision. The operation is considered complete."

Having said that, his expression became relaxed, because the operation had reached the final step.

"In terms of the operation process alone, implanting an artificial heart is not a very complicated operation."

"The main difficulty of the operation is to stop the bleeding. The heart is flexible as a whole, so it is easy to tear when the artificial heart is sutured."

"Patients with heart failure generally have poor heart function, liver function and blood coagulation mechanism, and are prone to bleeding."

"However, compared with hemostasis, the more difficult part is the timing of getting out of the artificial heart-lung machine after the patient is implanted with an artificial heart."

"That is to say, the surgical team needs to adjust the speed of the blood pump and control the blood flow of the heart to find the most suitable speed of the artificial heart."

"Normal heart blood flow depends on the body's self-regulation. When it is tense, the blood vessels dilate and the blood flow increases; after rest, the blood flow will slowly return to normal."

"The blood pump of the artificial heart is an advection flow. Once the speed is fixed, it can only pump blood at a fixed blood flow, and cannot be adjusted dynamically. If the speed is high, it is easy to suck the meat and cause damage to the pump; It cannot meet the needs of the whole body's blood supply."

"Because it is difficult to monitor the patient's blood pressure after the artificial heart is implanted, we need to observe the venous pressure, arterial pressure, interventricular septum, and whether the images of the atrial septum are in the center through ultrasound to find the most suitable rotational speed."

"The difficulty lies in how to adjust the most suitable speed for each person. Generally, it is fine-tuned within a certain range."

"Wait--fuck you, you're so awesome!"

Director Li, who was calm and stable, suddenly uttered a swear word, and the whole person became excited.

"It's unbelievable that Sanqing's artificial heart can automatically adjust, control the blood flow of the heart, and find the most suitable speed by itself."

"Usually, after other artificial hearts are implanted, the surgical team needs to adjust them to find the most suitable speed. I never expected that Sanqing's artificial heart is so intelligent that it can realize complete automatic adjustment."

"Hey, I've never seen such a heaven-defying technique!"

He was amazed, he couldn't stop exhaling the fragrance, but his hands didn't pause for a minute or a second.

Amid bursts of exclamation, the operation was quickly completed.

Putting down the scalpel, Director Li gently stroked the fine sutures with his hands, feeling the rise and fall of the patient's chest.

After a long time, he couldn't help but leaned down, leaned close to the patient's chest, and listened carefully.

Instead of the familiar heartbeat, there was a soft "humming" sound.

It was the faint but continuous sound of blood rotating in the artificial heart, replacing the thumping sound of the natural heart pumping blood.

At this moment, the rotating artificial heart and the remaining half of the heart in the patient's body merged into one and continued to move forward with load.

He is kept alive 24 hours a day, all year round.

******
Extremely fun!

This was Zhao Hong's first feeling after waking up.

Fresh air is inhaled from the nasal cavity, and you can breathe freely and smoothly without any hindrance.

The heavy burden that had been weighing on his chest for a long time has disappeared.

Breathing has become easier and smoother than ever before, and blood is rushing throughout the body, bringing a long-lost sense of strength.

At this moment, he felt that he had gained a new life.

Open your eyes and look at the white ward, which is both familiar and strange.

Memories flooded in, pounding his brain.

He unconsciously touched his chest, felt a long suture, and felt a little confused.

"It looks like I was rescued again?"

"Yes, it seemed like I was watching a video about an artificial heart before I fell into a coma."

"I've already had an operation? Is it an artificial heart?"

"But why don't I feel anything? I can't find a power cord all over my body. It shouldn't be."

"How does this artificial heart charge? It always needs to be charged. How long have I slept?"

"Oops, it won't be a long time without electricity."

While thinking wildly, the door opened with a bang, and a doctor walked in.

Zhao Hong was overjoyed instantly, and shouted as if catching a life-saving straw: "Doctor, what's going on with me?"

The doctor looked at him with a smile on his face, as if looking at a rare animal.

"It's recovering very well, what a resounding cry it is."

"You had an artificial heart transplant yesterday, and the prognosis is very good. You can go to the field tomorrow and resume your normal diet."

"This is the intensive care unit of the Cardiac Surgery Department. Next, we will observe you for 10-14 days to monitor your physical condition. If there are complications or adverse reactions, we can intervene in time."

"This is the first stage of integration between man and machine. You have to do blood tests every day to detect blood coagulation function, heart rate, blood pressure, kidney function, electrolytes, urine output and other indicators."

"One of the most important postoperative complications is bleeding and thrombus. During this period, you need to take anticoagulant drugs on time to prevent the formation of thrombus, so blood tests are required to adjust the dosage every day."

While examining his body, the doctor carefully explained the postoperative precautions.

"The artificial heart you installed has no external wires, so the chance of wound infection is not high. The outer shell and pericardium of the artificial heart are made of biological protein materials, and only the inner core is made of metal. Generally speaking, the rejection reaction will be relatively small. This saves money. A lot of trouble."

"In the future, remember to charge it every day." The doctor picked up what looked like a power bank from the bedside table and put it in his hand.

"This thing is your lifeblood, and you can't forget it wherever you go. Even if you lose your wallet and mobile phone, you can't lose this thing."

"There are batteries and controllers inside. You can wirelessly charge your artificial heart at any time within three meters. It can last for about 10 hours. There is a power display on it. If it is lower than 50%, there will be a reminder, and then you plug it in. Just plug it in and charge it.”

"Of course, the battery can also be removed and charged with other chargers, so I suggest that if you go out, you'd better bring two spare batteries."

"With this thing, you will not be affected by bathing, exercising, and swimming in the future. Of course, if you go into the water, it is best to hang it in a plastic bag."

"Anyway, it's not big, it's bigger and heavier than a mobile phone. I suggest you keep it in your pocket and develop the habit of carrying it with you."

"The artificial heart in your body also has a built-in power supply. It can last for an hour or two after being fully charged, so if you are at home, you can put it nearby. As long as you are within range, it will automatically charge and stop when it is fully charged. It is very convenient. "

Hearing the doctor's words, Zhao Hong was dumbfounded.

"It's so advanced, it can also be charged wirelessly?"

"I don't have to run around with a bulky battery or run a wire through my stomach?"

He took the power supply, looked and looked, surprised and delighted, and felt that he was so lucky.

"Thanks to Sanqing, I can use such a good artificial heart. It's not as troublesome as the patient said. It's so convenient."

The only thing that worries him now is how long this thing will last.

"Doctor, this artificial heart won't break after a short period of use, right? How long will it generally last?"

In his mind, Sanqing's products are of good quality and should last for two to three years.

Anyway, no matter how long it takes, I will earn it myself.

After all, before the heart was changed, the doctor had issued a critical illness notice, saying that he would not survive this year.

The doctor pondered for a moment, then shook his head and said, "We don't know about this. The expected service life is at least 15 years. If it is well maintained, it can be used forever, but this is a new product, and you are the first to use it." People, so how long it will last depends on you.”

Zhao Hong breathed a sigh of relief, and said with a smile: "It's okay, I just picked up this life, as long as I can use it for next year, it will be enough. If I use it for another year or two, I will make a lot of money, haha .”

In the next few days, he began to slowly recover his body, trying to get used to his artificial heart.

His body had to get used to the artificial heart, and the artificial heart had to get used to the pumping of his blood.

The two sides continue to work together to form a delicate but stable balance and maintain it.

As for the living habits, it is the same as before, except that there is an extra power supply.

Every morning at five o'clock, the first thing he does when he wakes up is to put the power supply in his pocket, and then use the instrument and smart watch to know his body temperature, weight, speed, flow rate, power, heart rate, blood oxygen, etc., and record them in the diary .

The blood pressure is measured five times a day. In fact, the doctor requires one time in the morning and one time in the evening, but he is worried and will measure it several times a day.

After taking the anticoagulant, he will go to the gate of the intensive care unit to meet his son in the afternoon, and make 10-minute phone calls through the glass.

Before going to bed at night, the last thing is to connect the power supply to the charger and plug it into the bedside socket to charge, so that he can sleep well, and don't have to worry about what to do if he oversleep and the power supply runs out.

After a long time, he seemed to have a low battery phobia, and he had to carry a power supply with him wherever he went, and check the power at any time, for fear that an oversight would drain the battery and cause him to die of shock.

The doctor also had nothing to do with his obsessive-compulsive disorder and could only let it go.

Ten days after the operation, his physical condition recovered well and he was transferred to the general ward.

After another week, all physical indicators showed good, and he was discharged home.

So far, his life has returned to normal, no different from before.

Just need to pay attention to one thing, usually stay away from magnetic fields, and places like subway security checks should be avoided.

If you really want to take the subway, you can show the staff the emergency card issued by the hospital and explain your situation, so as to avoid passing the equipment.

In order to avoid accidents, he also tried not to go to crowded places and not to join in the fun.

If there are many people on the subway, he will wait for the next one, or take a taxi.

The thing that satisfies him most is that he has the strength to walk. After eating every day, he will go out for a walk to complete the amount of exercise required by the doctor, usually one kilometer, and sometimes three to five kilometers.

But he doesn't go out of the community, he just walks around the community, stopping to chat with acquaintances.

At the age of 60, with a new heart, he is already very satisfied with this amount of exercise.

He gave up his two previous hobbies, drinking and playing cards.

The former is not good for health, and the latter is not good for health because of the second-hand smoke in the chess and card room.

Now he pays special attention to health, and even has a new hobby, dancing square dances with the old ladies in the community.

The amount of exercise in square dancing is not large, and he doesn't need to dance too vigorously. It is enough to just twist his body at will and feel the freedom.

Standing in the crowd, stepping on the beat, dancing briskly, without even becoming short of breath.

It is completely impossible to see that he has ever had an artificial heart implanted, and his whole body is perfectly integrated into this cheerful atmosphere.

Over time, Zhao Hong gradually got used to the existence of the artificial heart, and the so-called precautions became his new habit and integrated into his post-illness life.

He planned to wear it for life, and the word heart transplant, even in his dreams, never appeared again.

"It's enough to be able to live well. The things of these two months, if you think about it, it's like a dream."

He often said this to his son, with a contented smile on his face.
