medical road high rise

Chapter 495
Chapter 498 Keep improving
"call!"

Qin Feng exited the training room again, heaving a sigh of relief. This time, to be on the safe side, he trained in the training room for a total of 20 times. In fact, starting from the No. [-]th time, Qin Feng did not make any more mistakes, but Qin Feng did not Don't worry, keep improving.

On the other side, Zhao Guoping quickly contacted the blood bank and the blood transfusion department, and directly matched the blood to the nurse.

"Venous cut, rehydration!"

"Strictly monitor arterial pressure and neutral venous pressure, and correct shock."

"Director Zhao, the director of the general surgery department is not sure about this operation." The hospital came back panting.

"Then I'll go." Zhao Guoping didn't hesitate.

"Director Zhao, let me come." Qin Feng said.

Zhao Guoping looked at Qin Feng, "Can it work?"

"No problem, I'm sure." Qin Feng said firmly.

Time was tight and the task was heavy, Qin Feng didn't dare to waste time casually, so he asked Zhao Guoping to help with the doctor's order, and the nurse directly prepared for the operation.

"Brother Qin, I just got the news that the patient is still a pregnant woman."

"Oh, I see."

When Qin Feng was in the training room, the reason why he failed twenty times was because the patient was a pregnant woman, and Qin Feng didn't know about it at all.

Pregnancy complicated with heart disease (heart stabbing) is itself a very serious complication, and the mortality rate of pregnant women is extremely high, which is the first non-obstetric death of pregnant women.

Similarly, due to changes in hemodynamics during pregnancy, blood hypercoagulability, and metabolic changes, the burden on the heart of pregnant women will increase, which may worsen the condition, resulting in cardiac decompensation, acute pulmonary edema, and so on.

At this time, the nurse's heart itself has been seriously damaged, coupled with the burden of pregnancy, the difficulty and risk of surgery and the degree of prognosis have increased proportionally.

"Brother Qin, I don't want to die."

"help me."

"Save my child."

The nurse woke up suddenly and spoke.

At this time, the nurse seems to have forgotten the pain caused by her heart, and what she cares most about is her crystallization.

As a first-time mother, I have had too many surprises and longings for this crystallization. Naturally, the greater the expectation, the greater the gap in fear.

The nurse's excitement caused blood to rush out, and Qin Feng took the initiative to hold her hand.

"Don't worry, I will definitely rescue you and your child, just sleep peacefully, it will be fine when you wake up." Qin Feng comforted.

Seeing the conviction and firmness in Qin Feng's eyes, the nurse nodded.

Qin Feng turned around and said to the anesthesiologist: "Local anesthesia first, ready for general anesthesia with endotracheal intubation at any time."

"Okay." The anesthetist quickly understood what Qin Feng meant.

Because at this time, the patient is in a state of low cardiac output and has extremely poor tolerance to anesthesia drugs, and it is easy to cause cardiac arrest during the induction process.

The anesthetist handed the prepared lidocaine local anesthetic to Qin Feng. Qin Feng began to inject the anesthetic. After waiting for 5 minutes, he made an incision in the middle of his chest.

"Prepare your own blood." Qin Feng turned to Zhao Guoping and said.

"Autologous blood?" Zhao Guoping reacted immediately, because no matter whether it is blood from the blood transfusion department or the blood bank, it takes time to come.

This time belongs to the vacuum period without blood, or the amount of plasma currently reserved in the emergency department is not enough, so another option is to use the patient's own blood.

After Qin Feng finished speaking, he instantly exposed the four chambers of the heart and the ascending aorta.

"Breast open."

Zhao Guoping hurried forward to help Qin Feng expose the surgical field. Qin Feng cut the patient's pericardium and found the patient's wound.

Heart hemostasis suturing surgery, seemingly simple, is actually very difficult.

Because it involves later repairs and the restoration of normal function of the heart, and if special parts are damaged, the difficulty will increase proportionally.

In the training room, Qin Feng already knew that the patient's wound had damaged the coronary vessels, which was also a heavy blow to the entire heart.

Coronary arteries are channels that provide blood and oxygen to the heart, and damage here, that is, myocardial ischemic necrosis, is much faster than myocardial infarction.

"Defibrillation electrodes, 20ws discharge." Qin Feng said.

Zhao Guoping was stunned for a moment, and the deputy director of the Department of Cardiac Surgery who just came in took over the work in Zhao Guoping's hands.

"Old Zhao, let me do this one, I know it well."

"Xiao Qin wants to use defibrillation electrodes to induce ventricular fibrillation to control bleeding, and strive to suture the coronary vessels quickly in a short time." The deputy director of cardiac surgery explained.

This technique is not used in ordinary operations, but is only used in rescue, especially when conditions are lacking and medical equipment is insufficient.Surgery must be performed when there is no extracorporeal circulation device or in emergency conditions, and it is performed when there is no way to stop the blood flow in time.

The deputy director of the Department of Cardiac Surgery felt that Qin Feng's method was bold, but also very good.

Following the operation of the deputy director of the Department of Cardiac Surgery, Qin Feng began to suture.

In fact, the effect of the defibrillation electrodes is very obvious, but the time is very short, only about 1 minute. In such a short time, Qin Feng quickly started to suture the ruptured coronary artery.

The deputy director of the Cardiac Surgery Department could feel some kind of aura coming from Qin Feng. This is a kind of aura that can only appear after dozens of similar surgeries. He himself seems to be inferior to Qin Feng in this respect.

In 30 seconds, Qin Feng sutured the coronary artery.

"Establish extracorporeal circulation, prepare to repair the heart, and prepare 3-0 non-invasive sutures at the same time." Qin Feng said.

"This wound is a bit..." The deputy director of the Cardiac Surgery Department frowned.

Because Qin Feng had just sutured the blood vessels and had to turn the arteries, and the next operation had to avoid the coronary blood vessels. This operation was extremely difficult, adding [-]% to the difficulty of the operation.

Soon, the deputy director of the Cardiac Surgery Department discovered that Qin Feng had made a small spacer in the deep layer of the coronary vessel, and then performed interrupted mattress sutures.

"This step is good. It can prevent myocardial infarction caused by coronary artery tying." The deputy director of the Cardiac Surgery couldn't help but praise.

Others in the operating room looked at the deputy director of the Cardiac Surgery Department. Only then did the Deputy Director of the Department of Cardiac Surgery realize that he was a little agitated. His face turned red and he lowered his head to continue working as an assistant.

Qin Feng's next step is to deal with those lifeless necrotic myocardium, these necrotic myocardium stay in the atrium, only harmful but not beneficial.

Time passed by every minute and every second, and the operation gradually came to an end.

"The operation is complete."

Qin Feng turned off the extracorporeal circulation machine, and saw on the ECG monitor that the nurse's vital signs were recovering rapidly, and those dazzling reds slowly turned yellow.

Zhao Guoping was the first to applaud, and the others followed suit.

If it weren't for Qin Feng, maybe the nurse's life would have been lost. Qin Feng deserves the applause.
