Of course, in addition to biological valves, there are also mechanical valves.

The life of the biological valve is relatively short, and the price is relatively expensive, for example, the production of the aortic valve of pigs generally requires three or four pigs for splicing, and the subsequent manual processing process is very complex, and there are also many influencing factors in the production process, and the quality of the biological valve is difficult to grasp.

Even a particularly good quality bioprosthetic valve can only be used for 20 years, and even if it breaks down in two or three months, the patient must have a new valve replacement. In addition to pig pericardium, the import of bovine pericardium has been banned at present, because mad cow disease is found in many foreign regions.

As for the mechanical valve, because it is made of titanium alloy, the service life is about fifty or sixty years, and the disadvantage is that it needs to take anticoagulants for life, and it needs to be monitored regularly to adjust the medication according to the situation.

Mechanical valves are generally used in China, which are low in price and long-lasting, and are basically used for life. In contrast, biological valves are rarely used, and in young girls who are in the reproductive period or pregnant women during pregnancy, doctors will recommend the use of biological valves to prevent the impact of anticoagulant drugs on fertility.

Zhao Qiang's condition is more suitable for the use of mechanical valves.

In the next few hours, Zhou Yuan worked out a surgical plan based on all the examinations that the patient has done so far, the chief surgeon is still Zhou Yuan, the deputy chief physician of cardiac surgery is the first assistant, and Lu Chenxi of the thoracic surgery department is also essentially engaged in the heart, she is also experienced, so she participates in the operation as the second assistant.

Although He Jianyi is not specialized in this aspect, the three assistants are still competent.

The morning and afternoon of this day were busy with Zhao Qiang's operation.

There is too much work to be done in the preoperative preparation, and they must be able to understand all the circumstances of Zhao Qiang, only in this way can they have a thorough understanding of the surgical plan.

Zhang Ling and other little nurses were busy nursing Zhao Qiang, injecting various drugs to protect the heart muscle to provide protective measures for Zhao Qiang's operation.

At around twelve o'clock in the afternoon, Zhao Qiang was awake for a short time, and the family gathered around Zhao Qiang's hospital bed and talked for a while, and then Zhao Qiang fell into a coma again.

After the discussion of Zhou Yuan and others, the operation time was finally set at seven o'clock in the evening.

Patients with heart failure generally have complications of heart failure insomnia, it is difficult to fall asleep at night, once Zhao Qiang wakes up at night, but can not enter the sleep state, it is easy to cause problems such as irritability, in this case, Zhao Qiang is likely to have problems.

So, they finally decided to get the surgery done on the same day.

At half past five in the afternoon, Zhou Yuan and the others finished eating, took a shower, and prepared to adjust their state to deal with the upcoming operation.

The process of aortic valve surgery is not complicated and does not take long, it can be completed in about an hour.

But at six o'clock, Zhang Ling suddenly rushed into the office in a hurry, his face extremely pale.

"Zhou Yuan, Zhao Qiang has suffered a cardiac arrest!"

Zhou Yuan, who was closing his eyes and recuperating from his nerves, suddenly woke up: the most worrying thing has happened!

......

In the hospital bed, Li Li and Zhao Qiang's parents and others have all left, this is to allow the nurse to take care of Zhao Qiang, and at the same time prevent the family from having pathogenic bacteria - although these pathogenic bacteria will not affect normal people, Zhao Qiang's immunity is now very low, and he needs to ensure a sterile environment as much as possible.

At this moment, the instrument next to the hospital bed sounded dripping, and the part that originally showed the heart rate had turned into a dazzling blue question mark. This means that the instrument cannot detect the heartbeat.

Either the heartbeat has stopped completely, or the heart is beating so subtle that it can't be detected by the machine at all.

"The pulse is extremely weak!" He Jian said with a serious face.

Zhou Yuan glanced at the instrument, and then looked at Zhao Qiang on the hospital bed, who was still bloodless, and the temperature on his body was not high, about thirty-six degrees.

"The patient's blood flow rate is so small that you can't tell what the patient is doing!" said the cardiac surgeon, a little numb.

He has seen too many patients, and he has not been rescued at this point.

In order to perform surgery, it is necessary to determine the condition of the heart and the state of the body based on the blood flow rate. If there were no physical signs, there would be no reference for the doctor's surgical measures to be implemented, but now the flow rate is so small that even the monitor can't detect it!

Zhou Yuan was silent for a moment, and immediately said: "Perform vascular guidewire testing!"

The deputy director of cardiac surgery hesitated, but He Jianyi did not hesitate, and directly picked up the scalpel that had been sterilized and made an opening in Zhao Qiang's left inguinal canal.

The metal guide wire is very thin, and it is placed in the blood vessel after the current is turned on, which can directly monitor the patient's blood vessels and signs in real time, but this method is generally not chosen, after all, it can not be operated on without surgery.

The deputy director of cardiac surgery continued to do chest compressions on Zhao Qiang, and the place where the previous sutures were previously sutured has been reopened.

Zhao Qiang had already opened a Hun before, so it was impossible to do chest compression surgery now, otherwise the wound would be collapsed directly, and he could only cut the sutures and compress the chest twice.

Because of the intrachest compression, Zhao Qiang's body was shaking, and He Jianyi was able to quickly operate in the interval between the compressions, and after more than 30 seconds, the patient's groin blood vessels were exposed. "Puncture catheters, arterial catheters. "

He Jianyi was just about to insert the metal guide wire into the patient's blood vessel, when he was suddenly stunned.

"Impossible! Zhao Qiang's blood vessels are completely flattened, and he can't insert the metal guide wire into it!" He Jianyi's face became extremely ugly.

"I'll come. "

Zhou Yuan directly stepped forward and took the guidewire in He Jian's hand.

I don't know why, seeing Zhou Yuan come forward, He Jianyi, who was already a little desperate, suddenly felt a lot more relaxed.

Zhou Yuan always works miracles...

"Lao He, come over and help with the compression, I have no strength!" said the deputy director of cardiac surgery through gritted teeth.

He's been doing six rounds in a row and is already feeling a little exhausted, in which case the quality of the compressions drops.

He Jian nodded and took over the job of deputy director of cardiac surgery.

More than ten seconds later, Zhou Yuan's relieved voice rang out: "Guidewire X has entered." "

Everyone hurriedly looked at the monitor, which was no longer a straight line, and extremely subtle changes could be seen!

Zhou Yuan walked to He Jianyi's side again at this time, recalling the bits and pieces of the perfect CPR, and the next moment, he spoke loudly and said, "Teacher, I'll come." "

This operating room seems to have become a stage for Zhou Yuan's performance, if it weren't for Zhou Yuan's can't be separated, I'm afraid there is no need for He Jianyi and these people to maintain Zhao Qiang's life, whether it is guidewire placement, cardiopulmonary resuscitation, cardiac diuresis, etc., he can complete it alone...
