Chapter 394

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

Biological valves have a short lifespan and are more expensive. For example, the production of aortic valves in pigs usually requires three or four pigs for splicing, and the subsequent manual processing procedures are very complicated. There are also many influencing factors in the production process. The quality is difficult to grasp.

Even a biological valve with a particularly good quality can only be used for 20 years, and it may even break in two or three months, and the patient must undergo valve replacement again. Except for pig pericardium, bovine pericardium has been banned from importing, because mad cow disease is found in many areas abroad.

As for the mechanical valve, because it is made of titanium alloy, it has a service life of about 50 or 60 years. The disadvantage is that it needs to take anticoagulants for life, and it needs to be monitored regularly. Not demanding, no need to take medicine.

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

Zhao Qiang’s situation 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 the patient had done so far. The chief surgeon was still Zhou Yuan. As a helper, the deputy chief physician of the Department of Cardiac Surgery, Lu Chenxi, of the Department of Thoracic Surgery, was essentially a cardiologist. She also has experience, so she participated in the operation as a second assistant.

Although He Jianyi did not specialize in this aspect, Sansuke was still competent.

Four people were busy with Zhao Qiang’s operation in the morning and afternoon of this day.

There is too much work to do in preoperative preparations. They must understand all of Zhao Qiang’s situation. Only in this way can they have a thorough understanding of the surgical plan.

Zhang Ling and other young nurses are busy taking care of Zhao Qiang, injecting various drugs to protect the myocardium, and providing protective measures for Zhao Qiang’s operation.

At about 12 noon, Zhao Qiang was awake for a short while, and the family gathered around Zhao Qiang’s bed and talked for a while, and then Zhao Qiang passed out again in a coma.

After discussions with Zhou Yuan and others, the operation time was finally set at 7 o’clock in the evening.

Patients with heart failure generally have complications of heart failure and insomnia, and it is difficult to fall asleep at night. Once Zhao Qiang wakes up at night, but cannot go to sleep, it is easy to cause emotional irritability and other problems. In this case, Zhao Qiang is likely to have problems.

Therefore, they finally decided to complete the operation on the same day.

At 5:30 in the afternoon, Zhou Yuan and others finished their meal, took a shower, and prepared to adjust to the upcoming surgery.

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

But when it was six o’clock, Zhang Ling rushed into the office suddenly, her face extremely pale.

“Zhou Yuan, Zhao Qiang had a cardiac arrest!”

Zhou Yuan, who was closing his eyes and rested, suddenly woke up: The most worrying thing happened!(Read more @ wuxiax.com)

…

In the hospital bed, Li Li, Zhao Qiang’s parents and others have all left. This is to allow nurses to take care of Zhao Qiang and prevent pathogenic bacteria from his family members. Although these pathogenic bacteria will not affect normal people, Zhao Qiang is now The immunity is very low, and it is necessary to ensure a sterile environment as much as possible.

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

Either the heartbeat stopped completely, or the heartbeat was too subtle to be detected by the instrument.

“The pulse is extremely weak!” He Jian said solemnly.

Zhou Yuan glanced at the instrument and then at Zhao Qiang on the hospital bed. The latter was still bloodless, and the temperature on his body was not high, probably at 36 degrees.

“The patient’s blood flow rate is too low, and it is impossible to judge the patient’s current condition!” The cardiac surgeon was a little numb.

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

To perform surgery, it is necessary to judge the condition of the heart and the state of the body according to the blood flow rate. If there is no physical sign value, there will be no reference for the doctor’s surgical measures, but now the flow rate is so small that 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 for a moment, but He Jianyi didn’t hesitate to pick up the sterilized scalpel and made an opening in Zhao Qiang’s left inguinal canal.

········· Ask for flowers···································································

The metal guide wire is very thin and put into the blood vessel after the current is connected. It can directly monitor the patient’s blood vessel and physical signs in real time, but this method is generally not chosen. After all, it can be done without surgery.

The Deputy Director of Cardiac Surgery continued to give Zhao Qiang intra-chest compressions, and the previous stitches had been removed.

Zhao Qiang had previously operated on Hungary, so now it is impossible to perform chest compression surgery, otherwise the wound will be collapsed directly, so he can only cut the suture and perform the second chest compression.

Because of the chest compressions, Zhao Qiang’s body was shaking. He Jianyi could only perform surgery quickly in the gap between the compressions. After more than 30 seconds, the patient’s inguinal blood vessels were exposed. “Puncture catheters, arterial tubes.”

0 …….. …….

Just as He Jianyi was about to put the metal guide wire into the patient’s blood vessel, he was stunned.

“Impossible! Zhao Qiang’s blood vessels are completely flattened, and there is no way to insert the metal guide wire!” He Jianyi’s expression became extremely ugly.

“I come.”

Zhou Yuan stepped forward and took the guide wire in He Jian’s hand.

I don’t know why, seeing Zhou Yuan stepping forward, He Jianyi, who was already a little desperate, suddenly felt relieved.

Zhou Yuan can always create miracles…

“Old He, come over and help press, I’m running out of strength!” said the deputy director of cardiac surgery gritted his teeth.

He has done six rounds in a row and feels a little exhausted. In this case, the quality of the compressions will decrease.

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: “Guide wire X has entered.”

Everyone quickly looked at the monitor, it was no longer a straight line, and they could see the extremely subtle changes!

Zhou Yuan walked over to He Jianyi again at this time, recalling the perfect CPR, the next moment, he said loudly, “Teacher, I will come.”

This operating room seems to have become a stage for Zhou Yuan’s performance. If Zhou Yuan could not be cloned, I am afraid that He Jianyi would not need these people to maintain Zhao Qiang’s life, whether it was guide wire placement, cardiopulmonary resuscitation, cardiotonic diuresis, etc., he was alone. It can be done…spoon.
