"Prepare the balloon to expand." Wu Xiangdong also breathed a sigh of relief at this moment. He did not stop everyone from cheering. After all, this hard-won victory was too crucial for them.

"Brother Dong, let me come." Shang Lin, who was still in the back room at this moment, ran over without stopping.

He can be said to be the most excited person among the group. After all, Shang Lin knows better than anyone how difficult this surgery is.

In the face of shortage of equipment and materials, they actually took the lead in carrying out a PCI surgery here. You must know that this type of interventional surgery has just emerged in China.

Most hospital scholars are waiting and watching. I am afraid that only a few highly skilled general hospitals in the entire region can barely complete it. As for the effect, it is unknown.

At this moment, Shang Lin was lucky enough to be standing here, assisting Wu Xiangdong in completing the final expansion of the balloon. This was the highest honor for him.

When Wu Xiangdong saw Shang Lin running over to complete the balloon dilation surgery, he couldn't help laughing and scolding: "You kid, you looked like you didn't recognize your relatives just now, how come you know to call me brother now?"

Faced with Wu Xiangdong's teasing, Shang Lin suddenly blushed and didn't know what to say. After all, he just relied on his academic qualifications and profession to look down on everyone.

"Brother Dong, I was wrong." Shang Lin lowered his head, his attitude was very sincere.

After all, it was really important to him to be able to complete such an era-defining operation.

"Okay, then get ready to go on stage." Wu Xiangdong's whole hand was still a little numb from the stimulation of the electric current. Now that he saw Shang Lin taking the initiative to ask for help, he agreed.

After all, the most difficult part has been successfully completed, and all that is left is to simply place a ball bag. This is an opportunity for Shang Lin to practice.

"Thank you Brother Dong, I'll be fine now." Shang Lin nodded and bowed, immediately put on medical gloves and came to Wu Xiangdong.

"Here you go." Seeing this, Wu Xiangdong handed the guide wire to Shang Lin.

"Slow down, slow down." Such a seemingly simple action frightened Shang Lin. He quickly held up his hands and carefully took the guide wire.

The moment the guidewire was placed on his hand, Shang Lin stared, his hands trembling with excitement as if he had obtained a peerless treasure.

"Come out." Seeing this, Wu Xiangdong shook his head helplessly, and then warned: "When the balloon is inflated, remember not to apply enough pressure at once, but to do it slowly, little by little. Only in this way can all the thrombi be squeezed out to block the blood vessels.

on both sides."

Although Wu Xiangdong handed over the control to Shang Lin, he did not act as a hands-off shopkeeper, but reminded Shang Lin at all times.

"I understand, please don't worry Brother Dong, I will be very careful." Shang Lin looked at the image on the screen and hooked his fingers on the guide wire to prevent it from shifting.

Immediately afterwards, Shang Lin began to inflate the balloon. As the pressure continued, the balloon attached to the guide wire began to expand and become larger.

The thrombus that was originally firmly blocked began to move toward the coronary artery wall under the squeeze of the balloon.

Wu Xiangdong held on to the time, and then said to Shang Lin: "Okay, wait a moment."

Upon hearing Wu Xiangdong's instructions, Shang Lin immediately stopped applying pressure. As he breathed a sigh of relief, he realized that his palms were already sweaty.

"Dr. Kong, help me take another X-ray. I need to see the angiogram of the blocked blood vessels."

"no problem."

At this time, Dr. Kong, who was guarding the defibrillator, saw that the patient's heart rhythm returned to normal, so he put down the electrode pads on his hands, ran to the back room and pressed the button to take the X-ray.

With a sound, the X-rays that had been taken were transmitted to everyone's eyes.

"Is this open?"

The lumen, which was originally so narrow that blood flow was almost invisible, has begun to restore blood flow supply.

"It's only 50% open now." Wu Xiangdong looked at the development on the X-ray, then turned to look at Li Yanan: "How is the patient's condition now?"

"Doctor Wu, the patient's vital signs are much better than before." Li Yanan, who was closely observing the changes in the patient's condition, found that the patient lying on the examination bed did not look as painful as before.

"Okay, continue to observe." Wu Xiangdong nodded, and then he asked Wan Zhihua at the bedside: "How is the patient's current respiratory status?"

"Spontaneous breathing has been restored. Considering that the patient had a sudden heartbeat and respiratory arrest just now, in order to prevent cerebral hypoxia caused by temporary loss of consciousness, the patient is now given high-flow oxygen therapy, with an oxygen flow of 6L/mi.

."

At this time, Wan Zhihua had already removed the simple respirator and began to connect the oxygen cylinder with a catheter to inhale oxygen for the patient.

When Wu Xiangdong heard this, he had already calculated the patient's oxygen concentration to be 45% based on the oxygen therapy formula.

"Okay, no problem, continue to give the patient oxygen according to this oxygen concentration."

After the arrangements were made, Wu Xiangdong looked at Shang Lin again: "Continue to expand the balloon, and be careful not to press too much to avoid tearing the lining of the blood vessel."

The reason why Wu Xiangdong asked Shang Lin to suspend dilation just now is because patients with coronary heart disease themselves are affected by the three highs, and the elasticity of blood vessels is far less than that of normal people.

The so-called three highs refer to high blood lipids, high blood sugar and high blood pressure.

These three diseases are common chronic metabolic disorders, and the affected people are usually obese people, mental workers, middle-aged and elderly people, and some workers who require long-term mental stress.

And when a patient suffers from any one of hyperlipidemia, hyperglycemia and hypertension, he or she will easily become a patient with "three highs" in the later stage.

Coronary atherosclerotic heart disease is the disease most likely to be suffered by patients with three highs.

"Doctor Wu, if we continue to dilate, will the patient's blood vessels become dissection?" Shang Lin held the guidewire in his hand, but never dared to continue the operation.

After all, hardened blood vessels are squeezed by the balloon, which can easily cause damage to the intima of the blood vessels. Once a blood vessel dissection forms, under the constant impact of high-speed flowing blood, it is very likely to tear the blood vessels, causing a fatal blow to the patient.

When Shang Lin thought of this, cold sweat broke out on his forehead, and his hands were shaking involuntarily. If his hands were shaking before because of excitement, then this time it was really because of fear.

"That's scary. Compared to your profession, this is just the simplest operation." Wu Xiangdong frowned and looked at Shang Lin, seemingly dissatisfied with his current performance.

After all, such a simple balloon dilation operation can be completed smoothly even if it is handed over to an intern who has just arrived from the hospital.
