Subsection 1

"Sister Xuezhu, you, do you remember me?"

After Li Wei finished speaking, he stood upright, and stroked his hair again, I don't know if it was because of excitement or joy, his expression was a little distorted, he was too nervous. Li Xuezhu was surprised at first, looked at Li Wei, thought carefully for a while, and then suddenly realized, smiled, and said:

"Remember, are you the brother from Huaxia?"

"Yes! Sister Xie can remember me. ”

said this, but Li Wei was thinking in his heart, why doesn't Sister Xuezhu remember my name! But immediately comfort yourself, if you don't remember, you can't remember! It also saves the need to explain the contradiction between past and present identities. After the meeting, Li Wei has been with Li Xuezhu, entangled in her left and right, Goryeo dialect mixed with Chinese, coupled with the gesture with his hands, Li Wei was very busy, and the sweat came down. Li Xuezhu saw that he was in a hurry like this, and she couldn't cry or laugh a little, and kept telling Li Wei to speak slowly, speak slowly.

During the conversation, Li Wei learned that Xuezhu's sister is doing well, and now she is just graduating from college, she is an intern singer in the Korean Music Troupe, but she is not very famous, and she came to the hospital to see a college classmate. Li Wei was very happy, he didn't expect that he was so close to a star singer. Time passed quickly, Li Xuezhu had already come to her classmate's ward, she held the doorknob with one hand, but did not push it open, and smiled at Li Wei, Li Wei also smiled stupidly. Li Xuezhu let go of the doorknob yes, bowed down and made a gesture to ask you to leave, Li Wei realized that it was indeed a little wrong to enter the stranger's ward, and then turned to leave. Li Xuezhu was about to push the door and enter the ward. Li Wei ran over again,

"Sister, do you have contact information? Can you write it to me? ”

Li Xuezhu thought for a while, nodded, took out paper and pen from her bag and left contact information for Li Wei. Looking at the words in circles, Li Wei was very happy and left with a smirk. While running, he said to himself:

"What a worthwhile trip today! There is nowhere to find the iron shoes, and it takes no effort to get them, oh yes! ”

Just when Li Wei was enjoying a beautiful encounter. There is an operation waiting in cold blood. This more urgent heart surgery came very strangely. Just when the cold-blooded handover with the dean was the most rebellious, a doctor suddenly came over to inform the dean and asked Huaxia experts to do the operation. Reviewed the medical records and medical conditions. Cold-blooded found that his condition was surprisingly similar to Kim Il Jung's. Minutes and seconds passed. For the sake of human life. There was very little time for cold-blooded consideration, and the monk and the knife boy gave him a firm look. They support all decisions made in cold blood. Cold-blooded looked at his watch, it seemed that the mountain cannon could not come over for the time being, and he said eagerly to the dean:

"Let's operate immediately, help me notify the assistant to come over, if there is a doctor to observe, it is recommended that there are no more than 5 people, let's make preparations and go!"

After listening to the monk's translation, the dean immediately began to prepare. Everything in North Goryeo was managed in a militarized manner, and the concept of Songun politics had been implemented everywhere, and the governor's orders were as swift and resolute as military orders.

"Dr. Li Dafu, please come to the operating room on the 4th floor immediately, Dr. Han is about to have a heart operation and needs your assistance."

After the monk's Chinese radio broadcast, the Korean language radio followed,

"The staff of Goguryeo Hospital have paid attention, and if they find Dr. Li, a Chinese expert, they will immediately lead him to the operating room on the 4th floor."

Subsection 2

A cold-blooded surgical suit, with a cold expression, Dao Zai is a doctor without a diploma, and his medical skills are also quite exquisite, especially Chinese medicine. Although Li Wei has experienced bloody rain, it is the first time to have surgery, and there is a slight sweat oozing from his forehead.

Cold-blooded while explaining and doing surgery, quite a master's style.

"Anesthesia generally uses endotracheal intubation and intravenous compound fentanyl, but my assistant Xia Jianfeng is a well-known Chinese medicine practitioner and can be anesthetized with a golden needle.

The needle application technique of the knife boy was as fast as lightning, and the doctors at the scene did not see it clearly. (In fact, the knife boy only used one success, and he could even fly a needle in the air)

"Now we're going to start taking veins, and you're going to see it." The knife hand patient abducts and rotates the lower limbs, and cold-blooded from the inside of the femoral artery under the inguinal ligament makes a long incision, revealing the saphenous vein, which is carefully peeled off with scissors.

"Attention! Do not damage the adventitia and lymphatic vessels! Each branch should be clamped as far as possible and cut off with a fine wire at a distance of 1mm from the main trunk of the vein, or it can be cut between metal clips, and then ligated with a thin wire on its proximal side, and the ligation should not be too close to the main trunk, and absolutely no electrocoagulation should be used to avoid damaging the intima! ”

After the vein was removed in cold blood, the nurse was instructed to inject normal saline containing heparin, and the knife boy checked for whether there was a narrowing of the lumen and any leakage caused by entanglement of the adventitia, and Li Wei filled the saphenous vein with cold heparin blood.

At the same time, cold-blooded began to establish cardiopulmonary bypass, first exposing the coronary arteries, cold-blooded touched the thickened stenosis with his fingers, and at the distal end of the coronary artery, at the most anastomotic site, the longitudinal incision was made with a scalpel, and then enlarged with scissors.

Under a series of continuous sutures, the three experts were very attentive, and the doctors of Goguryeo Hospital watched intently......

"The grafted saphenous vein segment is inverted so that its proximal end is anastomosed to the distal coronary artery and its distal end is anastomosed to the aorta, so that the venous valve does not obstruct blood flow. Continuous sutures can be used for larger coronary arteries and interrupted sutures for smaller diameters, but most use a combination of continuous and interrupted sutures. The anastomosis should be intima to intimum, which should be sutured tightly without leakage, and should not be too tight to cause the lumen to be narrowed. After the anastomosis, heparin solution is injected into the transplanted saphenous vein segment, and the aortic occlusion forceps are opened to re-beat. ”

Cold-blooded while narrating and operating, the movements are like flowing water......

Li Wei was responsible for stopping cardiopulmonary bypass, the knife boy carefully stopped the bleeding and placed a drainage tube, and the chest incision was sutured layer by layer in cold blood. The doctors of North Korea were amazed by the one-stop operation, and if it weren't for the operating room, they would have responded with warm applause.

Cold-blooded, calmly took off the mask and continued to explain:

"Coronary arteries are sometimes buried deeply, often affecting their separation and exposure. Generally, there is a shallow groove on the surface of the coronary artery that aligns with the direction of the vein, and the hardened artery can be palpated in the groove and gently separated with a knife to reveal the underlying artery. Sometimes the muscles on the surface of the blood vessels are about a few millimeters thick, making it very difficult to locate the blood vessels, but it is also possible to start from the distal visible blood vessels and separate them proximally to find a suitable site for anastomosis, and the deep buried coronary arteries can be cut along the superficial grooves of the surface. After the blood vessel is anastomosed, the transplanted saphenous vein or intrathoracic artery is sometimes found to be twisted or rotated, leading to blockage and surgery failure. The correction method is to clamp the two ends of the rotating blood vessel with two non-traumatic forceps, cut it in the middle of it, and make it straighten and then anastomize...... But the important thing is to ensure that the blood vessels are patency ......"

Before the cold-blooded words were finished, his expression suddenly became a little ugly, Li Wei hurriedly supported him and said to everyone:

"You've got the video filed! If you don't understand the terminology, please contact our translator, we still have books and materials for you, Dr. Han is too tired, he has stomach problems, let's go here! Dr. Han, hurry up and take an energy bar! ”

Li Wei took out a glass bottle with a blue liquid and handed it to the cold-blooded to take, this energy bar also attracted a lot of attention, because no one had ever heard of this thing. (To be continued......)
