In fact, the atmosphere in the operating room should be relaxed and happy in most cases.

The average duration of a large and medium-sized operation is about two hours and twenty minutes. It is actually a very serious loss for the mental health of medical staff. Imagine that a person needs to wear several layers of clothes and gloves, stand for two hours, keep his mind focused and hand movements accurate at any time. At the same time, he also needs to observe the status of other surgical personnel from time to time to ensure the best teamwork and not be able to speak casually. This is simply torture.

Therefore, doctors who don’t like to talk will almost become the best chat subjects in front of the operating table. They will randomly select a few topics and start chatting with all nurses, doctors, anesthesiologists, and even patients in semi-annumbness. Doctors with a stronger taste can even stroke out the intestinal obstruction with their hands while stroking shit out with the nurse while discussing which store to go to eat crayfish or fat intestinal noodles after get off work.

When the operation went smoothly, the operating room was usually bustling like a middle school classroom that had just finished class.

The operation began to be difficult, and the classroom after class seemed to ring the class bell again. The nurses began to deliver the equipment nervously, while the doctors did not say a word and were concentrating on competing.

The most terrifying time was that the operation was in trouble. After the classroom bell rang, it was not the beloved art teacher who came to class, but the head teacher with a black face. No one dared to make extra moves, and the class teacher's roar echoed in the whole classroom.

Therefore, it is particularly important to maintain a good atmosphere. For most medical staff participating in the surgery, as long as the surgeon is still chatting enthusiastically, there is nothing to worry about.

"Okay, now you can start suturing." Director Zheng carefully used seven or eight bottles of normal saline to clean the wound on Lin Lan's leg bit by bit. "First ensure the survival of the nerves and blood vessels, and don't move the femur."

A group of orthopedic men who were instructed nodded and began to carefully cut off the skin that was originally hanging outside. They placed the cut skin in a clean surgical tray aside and trimmed the fat layer and tissue under the skin bit by bit. The torn skin cannot be grown by sewing it directly. If it is not trimmed and thinned, and many small holes that can drain the flow are made on it, even if the skin is forcibly sewed back, it will only end up with necrotic amputation.

The subordinates focused their main energy on handling the skin flap. Director Zheng stretched out his arms and felt that he was still in good spirits. He signaled the young nurse beside him to bring a custom-made head-mounted magnifying glass for him. He lowered his head again and began to suture the damaged blood vessels.

Sun Lien hid in the corner and watched with relish. Especially when he saw Director Zheng preparing to suture the blood vessels, Sun Lien felt a little excited.

In today's surgical procedures, doctors are increasingly using vascular staplers to assist sutures. In addition to being a bit expensive and may increase the risk of vascular twisting, vascular staplers are simply the best choice for suturing blood vessels in surgery.

However, after careful observation, Director Zheng chose to stitch it purely by hand.

Could it be that the stapler of the blood vessels is not suitable for placing the stapler? Sun Lien watched Director Zheng sew a vein in less than ten minutes while thinking about the reasons in his mind. But it seemed that his observation was too careful. Suddenly, a line of conspicuous words popped up in front of Sun Lien's eyes and Director Zheng's head.

"Zheng Guoyou, male, 61 years old, with a mild myocardial infarction."

Sun Lien blinked a few times, and the word "slight myocardial infarction" became more conspicuous.

Just as Sun Lien decided to make an appointment for an MRI in a while to see if he was crazy, he suddenly realized that the sweat on Director Zheng's head seemed to have become more.

No, it was not just sweat. Sun Lien narrowed his eyes slightly. Director Zheng's face turned pale in an instant, and the originally extremely smooth movement on his hands began to slow down. The mask began to blow and retract significantly under his heavy breathing.

But the stitching action did not stop.

"No..." Sun Lien moved two steps to the side quietly and approached Director Zheng a little closer. Then, he heard a slight panting. Other orthopedic doctors were lowering their heads to deal with the flap, and were also discussing whether to eat braised pork in the cafeteria at noon. The young nurse beside Director Zheng was obviously paying attention to the delivery device, and even Zheng Guoyou was sweating profusely. The attention of the others in the operating room was attracted to the craniotomy of the neurosurgery. In the operating room of more than 40 square meters, Sun Lien noticed that Director Zheng's condition was somewhat inappropriate.

Can't delay any more. Sun Lien quickly made a decision. He first retreated and said something softly to Hu Jia's ear with curious face. Then, regardless of her shock, he quickly walked behind Liu Tangchun.

Liu Tangchun was hanging his hands and watching the resident in the neurosurgery make a hole in Lin Lan's skull. The drill bit was drilling in the bone, making a creaking sound.

"Director Liu." Sun Lien quietly touched Director Liu's waist with his butt, recalling the old man's attention, "Director Zheng's condition is not right."

"Yeah?" Director Liu asked with some confusion, "What's wrong? Didn't this old guy tease the little nurse?"

Sun Lien nodded helplessly and said, "Not only that, Director Zheng seems to be a little gasping, and the amount of sweat on his head is also quite heavy...Does Director Zheng have a problem with a heart attack?"

There is no small matter in myocardial infarction, and the mildest myocardial infarction can also cause severe pain that is enough to cause a collapse - some people are even more unlucky, they don’t even have pain, and they faint directly due to insufficient blood supply.

Director Liu's original diagnosis of regular medical training was just nonsense, but when he thought of Sun Lien's record of internal bleeding, Director Liu suddenly felt that he should pay attention to Sun Lien's discovery.

"Old Zheng, I heard from my family that you are not in good condition." Director Liu walked around the operating bed and came to Director Zheng who was completing the suture. He asked in a low voice, "How are you, are you okay?"

"Is something wrong..." Director Zheng completed the last stitch, and the somewhat damaged femoral vein was completely sewn by him. As the last stitch ended, Director Zheng seemed to have become a robot that suddenly had power outage, and his body softened backwards and fell over.

"Old Zheng!" Liu Tangchun was shocked and didn't care about the sterile rules of the operating room. He opened his hands and wanted to help Director Zheng. However, Sun Lien, who moved faster, was blocked in front.

Sun Lien caught Director Zheng, put the old man on the ground, quickly changed his position, knelt beside the old man, and started to press his chest with both hands. While pressing, Sun Lien shouted to Hu Jia, who had been prepared outside the door, "Don't stand there, push the rescue car!"
