Chapter 1306: What does it feel like to see someone die with your own eyes?

Time goes back to one day ago.

After the surgery notice was given to Feng Chunli, the first technical challenge faced by the surgical team of Nianwei Hospital was the artificial heart-lung extracorporeal circulation machine.

Without this thing, the difficulty of Feng Chunli's surgery would increase significantly!

An artificial heart-lung machine is an instrument that can simulate human cardiopulmonary activity. It can stop the heart and drain the blood from the heart cavity, providing a blood-free environment for delicate operations, especially foramen ovale suturing.

In this type of open-chest surgery, since the surgery is performed at the heart, the doctor cannot make any mistakes, so the field of vision required is extremely high.

The extracorporeal circulation machine can achieve this goal!

This high-tech advanced medical equipment was developed by a team of doctors from Shanghai Nanyang Hospital in 1958 and was domestically produced.

However, due to various social problems, doctors who are good at heart surgery have not emerged on a large scale.

Coupled with the limitations of the times and development conditions, there are only a handful of hospitals in the country that are truly capable of purchasing extracorporeal circulation machines.

So after asking Minister Lin Jianzhou and learning that there were only two machines in Yanjing, Li Xiangnan immediately asked Wang Defa and Fang Yu to split into two groups, one to go to the People's Hospital and the other to go to the 301 Hospital to borrow equipment!

Although Feng Chunli could still undergo open-chest surgery without this kind of extracorporeal circulation machine, the success rate of the operation would drop by 40% before it even began, and Li Xiangnan did not dare to take the risk!

After waiting for a full hour, when Feng Chunli had entered the operating room for skin preparation, two pieces of bad news came.

This was the first time I had a close brush with death.

The artificial heart-lung circulation machine in Room 301 is in use. The next operation is expected to be performed at night, and it needs to be completely sterilized before it can be borrowed, which will take another whole day.

In other words, at the earliest, we will have to wait until the day after tomorrow to get the instrument!

Obviously Feng Chunli couldn't wait.

The medical instrument can be borrowed.

But Defa received information that the last time this instrument was used was seven years ago. Although the external components are maintained once a year, it cannot be ruled out that the core components may be aged or damaged.

So the things can be borrowed, but if any medical accidents occur, Renmin Hospital will not be responsible, and Li Xiangnan and others are required to write a statement of responsibility.

Regardless of why a medical device has not been used for seven years, the rubber fittings inside will definitely age and need to be replaced.

Finding replacement materials will inevitably waste time.

Li Xiangnan could only let Wang De get angry.

The two artificial heart-lung machines in Yanjing could not be used, so he could only think of other ways.

I heard from Lin Chuqiao about Peking Union Medical College before. It was connected with the Rockefeller Group abroad, and received a lot of financial assistance and a lot of medical equipment.

With a try-it attitude, Li Xiangnan called Lin Chuqiao to inquire about the artificial heart-lung machine. Half an hour later, he got a reply that it could be borrowed!

This result relieved many doctors.

A few minutes later, Wei Lan went to Union Hospital and brought the imported artificial heart-lung machine.

There was no time to say thank you. After she learned how to operate the instrument and sterilized it, the artificial heart-lung machine was sent to the operating room.

However, borrowing the most critical and important instrument does not mean that the operation will be successful.

The second brush with death is here!

Feng Chunli was too young, only four years old.

Open-chest surgery requires general anesthesia and intubation.

But what dose is needed?

Ming Zhangju, who was in charge of the support, was responsible for the anesthesia mission this time.

The dose is too small and the effect of general anesthesia cannot be achieved. Feng Chunli will be stimulated during the operation, and her young age will inevitably lead to unstable factors, resulting in failure of the operation.

But if the dosage is too high, although the effect of general anesthesia is achieved, Chunli is only four years old. If the dosage is excessive, it may cause immeasurable brain damage, nerve damage, cardiovascular damage and respiratory damage to the child.

Children are especially sensitive to respiratory depression, so the dosage must be calculated more strictly.

In the past, there were no specialized anesthesiologists. The affiliated physicians who performed anesthesia during surgery also gave anesthesia to patients according to empirical formulas and clinical experience.

The entire surgical team had never had the experience of administering anesthesia to a four-year-old child.

This aspect is completely blank.

The dosages learned in textbooks are all rough estimates based on the age, constitution, and physical condition of adults, because the differences among adults are not that big, and complications are easier to resolve if they occur!

But for a child, a slight difference in dosage may lead to irreversible consequences.

Ming Zhangju was at a loss for a while. After asking senior doctors such as Lei Jin and Wang Qi for help but still getting no answer, he could only ask for help from Li Xiangnan who brought in an artificial heart-lung machine.

"According to weight!"

Unexpectedly, this extremely difficult problem for all doctors was solved by a word from Dean Li Xiangnan!

According to weight!

It can directly avoid various individual differences caused by aging!

This was a dosage concept that had never been seen before, and it gave the doctors in the operating room a feeling of enlightenment.

The second crisis was resolved so easily!

Everyone was sighing with emotion and admiring the operation, but time did not allow them to have too many emotions, so they quickly started the operation.

The third crisis came quietly.

After the airway intubation, Xiao Chunli vomited due to stimulation. Although she had been strictly required to abstain from water for 4 hours and food for 8 hours before the operation, she was still suffocated by the sudden food residue.

Fortunately, the artificial heart-lung machine was just about to be inserted and Xiao Chunli's heart had not yet been operated on, otherwise everything would be unimaginable.

Everyone immediately started cardiopulmonary resuscitation and it only took three minutes to save Chunli from death.

But half an hour later, everyone faced the fourth death crisis.

Normal open-chest surgery has extremely complex steps.

After endotracheal intubation and general anesthesia, Xiao Chunli's respiratory and circulatory functions were monitored.

Then the muscles were cut open along the midline of the sternum to expose Xiao Chunli's heart; then, after the pericardium was cut open, an artificial heart-lung machine was used to suspend the pericardium to expose the right atrium and foramen ovale area.

The real difficulty lies in the heart incision and repair.

As the chief surgeon, Li Xiangnan had to make a small incision in the right atrium to directly expose the foramen ovale and create specific operating space for the operation.

The artificial heart-lung machine then began to work in full force. After emptying Xiao Chunli's heart of blood, Li Xiangnan and others quickly used double-ended needles and 4-05-0 polypropylene sutures to continuously suture the edges of the foramen ovale.

During this process, it is important to note that if the foramen ovale is large or the tissue is weak, a polytetrafluoroethylene or autologous pericardial patch should be used and fixed on both sides of the atrial septum.

And this is when the danger arises.

During the process of emptying the blood and exposing the visual field, the stimulation of the catheter caused a huge response of the heart, which subsequently triggered arrhythmia.

There was no time to think too much at this time. If Xiao Chunli's malignant arrhythmia was not intervened in time, she would immediately die of acute heart failure.

"Perform CPR immediately, use the defibrillator for synchronized shocks! Remove the catheter, administer epinephrine! Quickly..."

"At that time, after Xiao Li shouted this, Xiao Chunli's face was next to my hand. I saw with my own eyes that her face had turned completely white, and there were traces of tears in the corners of her eyes... I could feel that Xiao Chunli's life was slipping away, and her body was getting colder bit by bit..."

Wang Defa covered his face with his hands. Thinking of that thrilling scene still made him unable to control his emotions. His shoulders trembled and he could hardly suppress his emotions.

Feng Sanshun sat beside him, squatting on the ground, biting his collar with his teeth. His face was already covered with tears, and he sobbed, not daring to let himself cry out loud.

Ge Dongxu and Xia Haiyang stood beside them with red eyes, biting their lips and remaining silent.

"Defa,"

Qin Ruobai gently pressed his shoulder, pursed her lips and said comfortingly: "It's okay now, Chunli is rescued! She is rescued! You and Xiangnan are all amazing, really amazing! You are all great!"

She could imagine that the twenty-hour operation would be a protracted battle of physical exhaustion, and even more so a terrifying battle of mental exhaustion.

"Xiao Wang, you and my grandson are both amazing people!"

Suddenly an old voice sounded.

Wang Defa and Qin Ruobai turned their heads at the same time and stood up immediately.

"Grandma Song? Why are you here?" Qin Ruobai stood up with great joy.

Wang Defa stood up a little awkwardly and wiped the tears from the corners of his eyes embarrassedly.

"I came to see Xiao Li. I passed by this corridor and overheard your conversation! I overheard it for twenty minutes longer without noticing..."

Yu Jingran walked over with a smile and said kindly, "That child is so lucky to have met you! I am very moved when I heard it!"

Wang De blushed and said embarrassedly: "We didn't do anything. It's mainly Xiao Li's credit!"

“Don’t say that,” Yu Jingran shook his head. “A skyscraper is not built with just one brick! You all deserve praise!”

After she finished speaking, she smiled and grabbed Qin Ruobai's hand and asked, "I heard from the doctor downstairs that Xiangnan is still sleeping?"

"Grandma, now you're here. He's very telepathic and will definitely wake up! Let's go and see him!" Qin Ruobai took her hand and led her upstairs with a smile.
