“Old mu is in surgery. What’s wrong?” Su Yun asked lazily.

“The patient’s heart has stopped beating!” The nurse turned around and ran back after she finished shouting.

Uh …

A neighboring spell?

Su Yun stood up immediately. Through the lead glass, she saw Zheng Ren turn around. Without even tearing off her sterile clothes, she opened the airtight lead door and strode out.

“Elder Wu, don’t worry. I’ll go over with boss.” Su Yun strode away, not forgetting to explain to old Wu.

At old Wu’s age, he was really afraid that he would get a heart attack first if he participated in the emergency treatment.

The operating theater of the People’s Hospital of Pengcheng Development Zone was not big. There were only five operating rooms. The airtight lead door of the operating room, which had an operation red light on, was closed, and panicked voices came from the operating room.

“Push the medicine! Atropine, 1mg!”

Zheng Ren quickly walked over and saw a pale system panel. The diagnosis on it was already blurry. He could vaguely see the diagnosis of coronary artery hardening heart disease, carotid artery narrowing, and so on.

The doctor from the cardiology department was performing chest compressions while the nurse drew out medicine and prepared to administer an infusion.

The screen of the operation showed that the carotid artery was located at the intersection of the right internal carotid artery. The pressure sensors here were more sensitive, and reflex adjustment was mainly able to respond to the pressure sensor in a short time, even within a few seconds.

This required a coronary artery stent. The heart stopped when the surgery opened up the carotid artery, which was narrow.

Zheng Ren took a quick glance and understood the situation. He then entered the system operating theater.

Su Yun quickly followed behind Zheng Ren. When she saw that the nurse was a little slow in taking the medicine, she said,””Old he!”

Old he didn’t reply. Instead, he walked over in silence and determination. He walked to the ambulance, opened a syringe of atropine, drew it into a syringe, and injected it into the syringe.

Emergency rescue was a test of one’s mental strength and skill level.

The young nurse was like a new soldier who had just entered the battlefield. She was immediately frightened when she heard the roar of the cannon. She was not as skilled as old he, who was a veteran who had experienced countless battles of all sizes.

His skill level was average to begin with, and once he panicked, he would really be left with nothing.

“Old he, perform intubation.” Zheng Ren suddenly said,”circulating, push the ventilator over.” Su Yun, go and do chest compressions. Increase the strength and frequency of the chest compressions. “

Zheng Ren tore off his sterile clothes, removed his sterile gloves, and turned around to wash his hands.

Su Yun did not hesitate and walked to the surgeon’s side. With a bump of her shoulder, she pushed the surgeon away from the position where the heart was being pressed.

The Sorcerer was dumbfounded.

However, at this time, if a Doctor Who was confident enough to take over the rescue appeared, she would definitely not stop him.

At the beginning of the surgery, the bag was slightly opened, and the patient suffered from cardiac arrest. By right, the Department of Cardiovascular Surgery was very good at this kind of emergency first aid. However, after pressing on the heart for thirty seconds, they did not see the heart beating again, and they immediately panicked.

“You, go and charge the defibrillator.” Zheng Ren went to wash his hands, and Su Yun took over the command of the rescue.

He commanded the surgeon without any scruples, and he had the style of a Department Director.

Atropine, dopamine, and epinephrine were pushed in. Old he completed the tracheal intubation at the fastest speed and handed the bag bag to the assistant doctor.

Zheng Ren brushed his hands and entered, wearing a sterile coat.

“Boss, how do we do it?”

“The carotid artery is narrow, but we still need to open it. What about old mu?” Zheng Ren took a glance and saw that Su Yun was performing chest compressions at a frequency of 110 times per minute. The wave on the electrocardiogram had not recovered yet. Just like in the system’s operating theater, it was a little urgent.

“Boss Zheng, I’m here.” Mu Tao finished the last step of the operation and rushed in.

When the doctor from the cardiology department saw mu Tao come in, it was as if he had finally seen his Savior. He said in a hoarse voice,”Professor mu, the patient’s heart has stopped beating …”

“Boss Zheng, what should we do?” Mu Tao asked with a frown.

“You push the ventilator, I’ll lower the stent.” Zheng Ren stood at the position of the Sorcerer and looked at Su Yun.

“Why are you looking at me? if you’re not wearing lead clothes, then so be it. Just hurry up and do it.” Su Yun’s arms were straight as she continued performing CPR.

The airtight lead door slowly closed. Zheng Ren had already started to step on the line.

The position of the balloon was slightly changed, so Zheng Ren moved it in further. He found the carotid artery’s narrow spot, pried open the narrow section, and inserted the CRISTALLO idease 6 “9mmmmx40mm self-expanding stent.

As the carotid artery was opened, Su Yun’s movements also gradually slowed down.

The patient’s ECG monitor also gradually suppressed the fluctuations and returned to normal as he experienced venomatosis. After a few seconds, his heart rate returned to normal.

“Wear lead clothes.” Zheng Ren stopped stepping on the line.

Su Yun looked at the monitor’s value and nodded. She turned around and put on the lead suit with old he.

“…” The surgeon from the cardiology department stood at the side with a confused expression.

“Little sun, what’s going on?” Mu Tao asked.

“The patient was diagnosed with coronary artery heart disease and excruciating angina. Arteriosis of both lower limbs and carotid artery narrow. Initially, I wanted to solve the carotid artery’s narrowing first before putting in the stent, but I didn’t expect the heart to stop as soon as the bag was put in. “

Mu Tao nodded.

Obvious carotid artery congestion was an important risk factor for coronary artery stent patients to suffer from stroke during the perioperative period. The occurrence rate of stroke was as high as 3% to 11%, and it was positively related to the degree of carotid artery congestion.

The patient’s condition was clear, and there were no problems with the preoperative diagnosis and surgical indications.

The treatment was not wrong, and the surgery was normal. The carotid artery’s narrow problem should be solved first. It was just that the patient’s heart had stopped for a long time, so the man was stunned.

“Boss Zheng,” Mu Tao asked softly.

“Tell me about the surgery.” Zheng Ren said,”it shouldn’t be a big problem. Don’t be nervous.”

“The patient’s condition is much better. Do you still need a respiratory machine?” Mu Tao asked.

“I have to use it.” Su Yun came back wearing lead clothes and said in disdain,””Patients with coronary artery disease suffered stroke during the perioperative period because of carotid artery disease. The prognosis is very bad, and the mortality rate is about 50%.”

Mu Tao was an interventional physician, not a doctor from the cardiology department. He would have no problem if he were to help with the emergency treatment and perform a patient’s coronary stent surgery. However, when it came to more detailed things, especially those related to pathology and physiology, he was beyond his reach.

“Tell me about the process.” Zheng Ren reminded him again.

“The preoperative scan showed that the proximal end of the right internal carotid artery was 90% narrow. I used a super-smooth guide wire to send an 8f MPAI guide tube to the right common carotid artery, SpiderRX 5.0mm to the end of the right internal carotid artery, and sent a Sapphire 4.0MX20mm balloon, and gave 15 ATM. After five to six seconds, the patient’s heart stopped beating. “

The surgeon should be the director of the cardiology department of Pengcheng Development Zone People’s Hospital. Under Zheng Ren’s pressure, he became a junior doctor and began to report the surgery process.

In the emergency first aid, when there was basically no effect, someone would step forward and help. For the surgeon, it was undoubtedly a relief.

In the face of cardiac arrest, he could still command the resuscitation with such determination and confidence. It was needless to say that his skill level was much higher than his.

“Yes, it’s pressing on the carotid pressure sensor.” Zheng Ren said,”heart stop after balloon inflation, followed by ventricular fibrillation and malignant arrhythmia are common complications.”

“Boss Zheng, I thought I would have to give up on the surgery.” Mu Tao let out a long breath and said.

“No need. The cardiovascular activity Center in the brain controls the heart and blood vessels through the sympathetic nerves and vacuous nerves, so that the arterial blood pressure is maintained at a certain level. “

“When the balloon is expanded, the arterial pressure sensor will immediately send this information through the nerve to the Cardiovascular Center. The activity of the Cardiovascular Center will change accordingly, causing the heart rate to slow down, the peripheral blood vessels to expand, and the blood pressure to drop.”

“The rapid increase in internal pressure of the balloon, the large diameter, the high pressure, the long expansion duration, and the strong sensitivity of the pressure-sensitive reflex may be the cause of cardiac arrest.”

“It’ll be fine once the surgery is over. He’ll recover after some time. ” Zheng Ren smiled.

“Old mu, where’s old Wu?” Su Yun suddenly asked.

“The teacher is seeing a patient in the operating room …” Mu Tao said.

“That’s fine. Prepare for the next surgery over there. This should be done soon.” Zheng Ren smiled.

“We don’t need to remove the heart stent, do we?” Su Yun looked at the Sorcerer and asked.

“No… No need. Sorry for the trouble.” The Sorcerer said politely in a low voice.

At this time, saving the patient was equivalent to saving himself, and the surgeon felt that no matter how he expressed his gratitude, it would not be too much.

However, she was still a little dazed. She was still immersed in the nightmare of the patient’s sudden death.
