Acute hemopericardium, as the name suggests, is a collection of blood in the pericardium.

As a tissue structure that houses and protects the heart, the pericardium is actually a membranous sac that covers the heart. There is not much space between the fibrous serous sac and the heart, and it mainly plays the role of limiting the excessive enlargement of the heart chambers and isolating the heart and other organs. The pericardium contains some pericardial fluid, which mainly acts as a lubrication when the heart beats.

Due to the small size of the pericardium, an increase in fluid accumulation of more than 150 ml can cause extremely serious cardiac tamponade - when the pericardium is filled with blood, it will severely squeeze the heart, and the squeezed heart cannot relax, and the atria cannot store enough venous blood, resulting in difficulty in the heart and severe reduction in ejection ability.

To explain in layman's terms, the effect of hemopericardium on the heart is like a hand - the heart that is tightly held by the hand naturally cannot beat and work normally.

Sun Lien only took 20 milliliters of pericardial blood, and in exchange for a significant improvement. This shows that Dr. Cao's current hemopericardial problem is very serious, and there is no extra space in the pericardium to continue to accommodate blood, so it can be significantly improved after a little blood is withdrawn.

At present, there is only one available treatment method - emergency thoracotomy. There is no other way.

Emergency surgery is different from those emergency surgeries and elective surgeries, and the most important feature is "emergency".

This may sound like nonsense, but in modern medicine, when auxiliary departments are playing an increasingly important role, emergency surgery has brought surgery back to the era before the birth of X-ray. Except for a small amount of body surface reports and data during the emergency consultation, all the contents of the operation need to be confirmed by the eyes and hands of the surgeon. Any strange situation can happen, and the only way to deal with it is to rely on the doctor's exquisite skills and bold and careful intraoperative strategy.

Without imaging data as a reference and without corresponding medical history as a basis, it is an emergency operation in the emergency department after rapid anesthesia.

Today's operating room has a completely different atmosphere than usual.

The highest-ranking doctor in the Department of General Surgery on duty in the hospital is Deputy Director Chen Hua. Due to the large number of organs that may be involved in emergency thoracotomy, Chu Guoqiang, director of cardiac surgery, was also invited to the scene.

Time was of the essence and Dr. Cao's condition was critical, and the exchange of views between the two surgeons was carried out during the thoracotomy.

"How did you do that?" Director Chu Guoqiang is not very old and quite short. He wore a mask, frowned and looked at Dr. Cao, who had been anesthetized on the bed, and asked, "Isn't this Director Wang's student?"

"Doctor's trouble. Director Chen explained succinctly, "The one who stabbed the person jumped off the building, and I don't know if he is dead or alive." ”

"Huh?" Director Chu was startled, and then said angrily, "What the is this world!"

"What kind of world can it be. Director Chen sighed, watched the skin and muscles in Dr. Cao's chest being pulled apart by the hook, revealing his ribs, and shook his head, "The world of a young doctor with unlimited prospects who was stabbed with a knife by a patient!"

The first operating room has the largest space and can be kept on standby all year round for emergency surgery. But today, when the operation began in the first operating room, it was extremely crowded.

The doctors who were on call in the operating room, and who were not operating on their hands, all came to the first operating room spontaneously. Doctors and nurses who came late couldn't even get into the operating room. The unique spring door in the operating room of the Fourth Hospital was leaned on by two doctors, and the doctors and nurses who hurriedly came after changing into their hand-washing clothes could only stand on tiptoe outside the operating room anxiously and look inside.

They are all anxiously waiting for news, waiting for news that their colleagues have turned the corner.

However, Sun Lien is not among them.

The entire treatment team gathered, and even Dr. Pascal sat down in the small conference room with a gloomy face.

Sun Lien lowered his head, not knowing what he was thinking.

Yuan Ping'an wanted to go to the operating room to see the situation, but Sun Lien sat in his seat without saying a word, he wanted to open his mouth to say something, but was stopped by Zhou Ce with his eyes.

"So, what are we waiting for here?" Xu Yourong didn't care about Zhou Ce's eyes, she frowned, "Doctor Cao's injuries are all obvious external injuries, and there is nothing that requires differential diagnosis...... What's the point of us all sitting here?"

"There is one in the content of the differential diagnosis. Sun Lien raised his head, looked around in a daze, and then slowly replied, "The case ...... In Yuan Ping'an's place, you go and take a look. ”

Several people glanced at each other, and they all sat in their seats without moving.

"I'll take a look......" Dr. Pascal shook his head and stood up, slowly walking towards Yuan Ping'an. When he passed by Sun Lien, he raised his hand and wanted to pat Sun Lien's shoulder to comfort him, but seeing Sun Lien's silent appearance, Dr. Pascal paused, still shook his head and took his hand back again.

"Xiang ......" Sun Lien's mobile phone on the table rang, and Sun Lien, who seemed to be facing a five-digit delay just now, shook violently and snatched the phone.

"Sister-in-law......" Sun Lien's voice sounded very calm, but the tremor in his tone couldn't be covered. "Right...... I...... I'm in the hospital. ”

"Okay. After a moment of silence, Sun Lien nodded, "I'll wait for you at the door." ”

He hung up the phone and slowly stood up.

"You're busy first. Sun Lien walked towards the door of the small conference room as if sleepwalking, and he swayed open the door, "I...... I'm going to pick someone up. ”

The cold wind blew, and it seemed that snowflakes began to fall in the sky again. Sun Lien stood at the entrance of the hospital wearing a white coat, which was lifted by the cold wind and turned up and down behind him. Seems to be holding something back.

After a while, a small black dot appeared in Sun Lien's vision. It was Cao Xin's girlfriend Shen Yue who came. This northern girl, who is usually a little hot-tempered, staggered when she walked, pulling her backpack with her left hand and covering her mouth tightly with her right hand.

Sun Lien greeted her and silently supported her. Then I walked towards the hospital.

"The operation is ongoing. The sign of the Fourth Central Hospital was getting closer and closer, and Sun Lien whispered to Shen Yue, "Deputy Director Chen is in charge of the surgery, and Director Chu has been invited outside the heart...... He suddenly stopped. What's the use of saying this?

"Isn't his situation bad?" Shen Yue twitched his nose twice and said in a thick nasal voice, "I...... Do you need to notify his parents to come over now?"

Sun Lien walked into the rescue hall with Shen Yue, he patted the snowflakes on Shen Yue's shoulder, and nodded silently, "If you can, call now." ”
