"Old Mu is undergoing surgery, what's wrong?" Su Yun asked lazyly.

"The patient's heartbeat stopped!" The nurse shouted, turned around and ran back.

Well……

Next door surgery room?

Su Yunhuo stood up suddenly, and saw Zheng Ren turning around through the leaded glass, not even tearing off the sterile clothes. He opened the induction airtight lead door and strode out.

"Mr. Wu, don't worry, I'll go over with the boss." Su Yun strode away, not forgetting to explain to Mr. Wu.

Mr. Wu was so afraid that he would participate in emergency treatment, so he would first get his heart attack.

The interventional operating room of the People's Hospital of Pengcheng Development Zone is not big, with only 5 operating rooms. The air-tight lead door of the operation room with a red light during the operation is closed, and a panic sound comes from the operating room.

"Press medicine! Atropine 1mg!"

Zheng Ren walked over quickly and immediately saw a pale system panel, with the diagnosis on it blurred. You can vaguely see the diagnosis of coronary atherosclerotic heart disease, carotid artery stenosis and other diagnoses.

The doctor in the circulatory department was doing heart compression, and the nurse was pumping medicine and preparing for bolus injections.

The screen of the surgery shows that the carotid artery intervention site is at the bifurcation of the right internal carotid artery. Here the pressure receptor is more sensitive, and the reflex adjustment is mainly to respond to pressure sensing in a short time and within a few seconds.

This is to do coronary stents. The heart stops when the carotid artery is stenosis by preoperative surgery.

Zheng Ren glanced at it, saw the situation clearly, and went directly to the system operating room.

Su Yun followed Zheng Ren quickly. Seeing that the nurse was taking medicine at a slow speed, he said, "Old He!"

Lao He did not respond, but walked over directly, silent and firm. He walked to the rescue vehicle, opened a tropic, drew it into the syringe, opened the tee and directly pumped it in.

Emergency rescue tests psychological quality and technical level.

The little nurse was like a recruit who had just entered the battlefield. She was frightened when she heard the roaring cannons. How could Lao He be so skilled as a veteran who had experienced countless battles of all sizes?

Originally, the technical level is average, but if you panic, you will really have nothing left.

"Old He, intubate the cannula." Zheng Ren suddenly said, "Cycle, push the ventilator over. Su Yun, go for a heart compression, and increase the intensity and frequency."

After Zheng Ren said that, he tore off the sterile clothing, took off the sterile gloves, and turned around to brush his hands.

Without hesitation, Su Yun walked to the operator's side, and bumped his shoulders, pushing the operator away from the position where his heart was pressed outside his chest.

The craftsman was stunned.

However, at this time, if a doctor who can take over the rescue appears with confidence, she will definitely not stop her.

At the beginning of the operation, the balloon was slightly opened and the patient experienced cardiac arrest. In this regard, the circulatory department is very good at Circulatory Department, but after pressing for 30 seconds, the heart did not beat again, and he was immediately panicked.

"You, go and charge the defibrillator." Zheng Ren went to brush his hands, and Su Yun took over the rescue command.

He is a scrupulous commander and full of style as a chief director.

Atropine, dopamine and adrenaline were pushed in. Lao He completed the tracheal intubation as quickly as possible and handed the balloon to the assistant doctor.

Zheng Ren came in with his hands brushing in and wore sterile clothes.

"Boss, how do you do it?"

"If the stenosis of the carotid artery still needs to be opened, what about Lao Mu?" Zheng Ren glanced and saw Su Yun doing external heart compression at a frequency of 110 beats per minute. The waveform on the electrocardiogram monitoring has not recovered yet. Just like in the system operating room, it was also a little anxious.

"Boss Zheng, I'm here." Mu Tao completed the last step of the surgery and hurriedly ran in.

When the doctor from the circulatory department saw Mu Tao coming in, he finally saw a savior and said hoarsely: "Professor Mu, the patient's cardiac arrest..."

"Boss Zheng, what should I do?" Mu Tao asked frowned.

"You go push the ventilator and I'll get off the stand." Zheng Ren stood at the position of the surgeon and glanced at Su Yun.

"Look at what I'm doing. If I don't wear lead clothes, I won't wear them. Just do it quickly." Su Yun's arms were straight and continued to do CPR.

The airtight lead door slowly closed, and Zheng Ren had already started to step on the line at this time.

The position of the balloon changed a little, so Zheng Ren sent it inside again, found the place where the carotid artery was narrow, opened the stenosis section, and sent it to the ristallo ideale-se 6-9mmx40mm self-expansion stent.

As the carotid artery opened, Su Yun's movements gradually slowed down.

The patient's ECG monitoring fluctuations gradually returned to ventricular tachycardia, and after a few seconds, the sinus rhythm was restored.

Zheng Ren stopped crossing the line and said, "Go in lead clothes."

Su Yun glanced at the monitor's value, nodded, and turned around to wear lead clothes with Lao He.

"..." The Circulatory Department's Circulatory Department stood beside him with a confused look on his face.

"Xiao Sun, what's going on?" Mu Tao asked.

"The patient diagnosed it with coronary atherosclerotic heart disease, exertional angina pectoris; arteriosclerosis of both lower limbs; carotid artery stenosis. I originally wanted to solve the carotid artery stenosis first and then remove the stent, but I didn't expect that the heart stopped as soon as the balloon was in."

Mu Tao nodded.

Significant carotid stenosis is an important risk factor for perioperative stroke in patients with coronary stents. The stroke incidence is as high as 3% to 11%, and it is positively correlated with the degree of carotid stenosis.

The patient's condition is clear, preoperative diagnosis and surgical indications are no problem.

The treatment is correct, and the operation is normal, the carotid artery stenosis should be solved first. However, the patient's cardiac arrest was a bit long, so he was stunned.

"Boss Zheng." Mu Tao asked softly.

"Tell me about the surgery process." Zheng Ren said, "There should be no big problem, don't be nervous."

"The patient's condition has improved a lot, are you still using a ventilator?" Mu Tao asked.

"It must be used." Su Yun came back in a lead suit and said contemptuously: "Patients with coronary stenosis have strokes due to carotid artery stenosis during the perioperative period, with a very poor prognosis and a mortality rate of about 50%.

Mu Tao is an interventional doctor, not a circulatory department. If he helps with rescue and coronary stent surgery, he will be fine. But he will be unable to do something more detailed, especially pathology and physiology.

"Tell the process." Zheng Ren reminded again.

"Preoperative imaging showed that the proximal end of the right internal carotid artery was 90% stenosis. I used a super-slip guide wire to send an 8f mpai guide tube to the right common carotid artery, spiderrx 5.0mm to the distal end of the right internal carotid artery, and sent it to a sapphire 4.0mmx20mm balloon. After 15atm.5, the patient's heartbeat stopped after 6 seconds."

The surgeon should be the director of the circulation department of the People's Hospital of Pengcheng Development Zone. Under Zheng Ren's pressure, he became a young doctor and began to report the operation process.

Emergency emergency treatment, when there is basically no effect, someone stands up when it comes to the surgery, which is undoubtedly a relief for the practitioner.

Faced with cardiac arrest, I can still command and rescue with such firm and confident confidence. Is it more to say how much higher the technical level is than me?

"Well, it's squeezed into the carotid artery pressure sensor." Zheng Ren said, "After the balloon dilation, the heartbeat stops, and then ventricular fibrillation and malignant arrhythmia are common complications."

"Boss Zheng, I thought I was going to give up the operation." Mu Tao said with a long breath.

"No. The cardiovascular activity center in the brain controls the activity of the heart and blood vessels through the sympathetic nerve and vagus nerve, so that the arterial blood pressure can be maintained at a certain level."

"When the balloon dilates, the arterial pressure receptor immediately feeds these information to the cardiovascular center through the afferent nerve, and the activity of the cardiovascular center will undergo corresponding changes, causing the heart rate to slow down, peripheral blood vessels to dilate, and blood pressure to decrease."

"The pressure in the balloon rises too fast, is too large, is too high, is too long, is dilation lasts too long, and is too strong to have a sensitivity to pressure-sensitive reflex, which may be the cause of cardiac stopping."

"Just just be resolved, and you will recover after a while." Zheng Ren smiled.

"Old Mu, where is Mr. Wu?" Su Yun asked suddenly.

"The teacher is watching the patient during the operation..." Mu Tao said.

"It's OK. I'm going to prepare for the next surgery on that side, and this side should be solved soon." Zheng Ren smiled.

"We don't need to get the heart stent off." Su Yun asked at the sci-fi stent.

"No...no, I'm in trouble." The craftsman whispered politely.

At this time, it is equivalent to retrieving the patient back. The surgeon feels that it is not too much to express his gratitude.
