Chapter 1736

"What patients usually send you for dissection?" Zheng Ren asked.

"Most of them were sent here by people who died in the hospital, and there were a few victims of fighting. I can't touch the really big and important cases." Li Zhaosen said, "even if I need technical assistance, I go to the Municipal Bureau." Li Zhaosen said.

"Just yourself, afraid?" Zheng Ren glanced at the dead. His chest and abdomen had been dissected. He probably had seen them.

Su Yun put on his clothes and gloves and began to dissect.

"They are all dead. What's to be afraid of? The living are terrible." Li Zhaosen said.

With this gloomy atmosphere, his words were awesome. The body, like an annotation, silently agreed with Li Zhaosen's words.

Su Yun went directly to the dead and put the knife aside. He picked it up directly, took out his heart and began to dissect.

"There is no problem with the general structure of the heart." "There are no organic lesions other than congenital heart disease and myocardial infarction," Su said

Zheng Ren doesn't chat. He stands behind Su Yun and looks at Su Yun's anatomy.

He knows where Su Yun's tangled place is.

If the deceased had a heart attack, it means that Liu, who had a dispute with the deceased at that time, was jointly and severally liable. At least part of the responsibility is unshirkable.

But if it were not myocardial infarction death, but myocardial rupture, the medical staff who did cardiac compression at that time would have a certain responsibility.

A dilemma.

There was a smell of internal organs in the room, and the exhaust fan was not on. Zheng Ren frowned. He was really not used to the smell and said, "Miss Li, do you usually don't turn on the exhaust?"

"What are you doing with that thing? If you hadn't waited for boss Zheng, I would have done an autopsy in 20 minutes." Li Zhaosen said, "the taste hasn't spread yet."

Zheng Renzhen doesn't know how to describe Li Zhaosen.

"And the dead at the autopsy smell much better than the general teacher. Especially the general teacher who has just been fished out of the pool. The smell of formalin is the same as that of just lovelorn after anatomy."

"Do you have a girlfriend?" Zheng Ren stares at Su Yun to dissect his heart and asks casually.

"No, I have this job. Who will marry me?" Li Zhaosen didn't care, and answered casually.

"The heart rupture occurred near the apex of the left ventricular posterior wall. There was an acute large-area myocardial infarction in the rupture area. The rupture was irregular, about 1.2 × 0.8cm。” Su Yun continued to observe.

"The scope of myocardial infarction is relatively large, myocardial necrosis..."

He hesitated.

"Boss, do you find anything strange?" Su Yun asked.

"Open the three coronary arteries. Are you sure? Don't cut your hand." Zheng Rendao.

"Cut!" Su Yun said: "I have done 122 coronary artery bypass grafting operations."

"Just be careful." Zheng Ren said, "the scope of myocardial necrosis is too large. The whole heart seems to be broken, like a rotten peach."

"This kind of situation is very rare. When I dissected it, I also felt strange." Li Zhaosen said, "I have done an autopsy of patients with myocardial infarction. The situation of the elderly in their 70s and 80s is not as serious as him."

Su Yun didn't dissect the coronary artery directly according to Zheng Ren. He began to look at his heart.

"What do you think?" Zheng Ren asked.

"It smells bad." Su Yun said, "like rust, is it caused by chemical poisoning?"

"The liver is dissected. There is no big problem. It's a little alcoholic liver at most. It's not very heavy." Li Zhaosen said.

"Strange." Su Yun changed his heart in another direction.

"Don't move the coronary artery first. Dissect the left heart. The heart is large as a whole and the ventricle is hypertrophic, especially the left ventricle." Zheng Ren suddenly said loudly.

The heart of an adult is about the size of his fist. A fist as big as a sandbag is just an adjective. Generally speaking, the heart is not very big.

In particular, most of them are in Su Yun's hands. It is difficult for Zheng Ren to see the size clearly.

"I said something wrong!" Su Yun said, "I forgot such a big thing when I did an autopsy for the first time."

With that, he began to dissect the heart.

Su Yun's scalpel is different from Zheng Ren's. His technique is exaggerated or dazzling.

"The whole heart is enlarged, and the volume is about 10% larger than normal. Taking the left ventricle as an example, the left ventricle is dilated and hypertrophic. Considering that the dead is accompanied by left heart failure. There is bleeding in the myocardium and fibrosis in a large number of myocardium!" Su Yun stated while dissecting.

"Myocardial contraction zone..." soon, his words stopped.

"Necrosis?" Zheng Ren's eyes narrowed.

"I just wanted to see here when I received your call, boss Zheng." Li Zhaosen also saw this, and he immediately explained.

Myocardial contraction band necrosis means a very important thing - basically, only methamphetamine abusers will have this physiological change.

Not occasionally, but abuse, long-term, large!

“MD！” Su Yun scolded excitedly, "boss, this strange smell, I know what it is!"

Zheng Ren also wants to understand what it tastes like.

People who take methamphetamine smell a lot.

There is a huge gap between Zheng Renhe and Su Yun's social circle and such people. They can hardly see such people at ordinary times, so they don't react at the first time.

The same is true of Li Zhaosen.

What you see in the book is only boring words, which can't replace the smell of your nose. Li Zhaosen hurried to turn on the exhaust fan. He didn't seem to get better until he heard the buzzing.

"The mechanism of myocardial lesion is multifactorial, including catecholamine excess, coronary artery spasm and ischemia, increase of reactive oxygen species, mitochondrial damage, changes of myocardial metabolism, and direct toxic effects."

Su Yun nagged while dissecting. Zheng Ren knows that he is thinking.

Things have turned for the better, or even reversed.

"Chronic poisoning can cause myocarditis, cell infiltration, myocardial hypertrophy, myocardial fibrosis, dilated cardiomyopathy, accelerated atherosclerosis, aortic dissection and even heart rupture." Su Yun said, "now it can almost be determined that the heart rupture caused by methamphetamine poisoning has nothing to do with trauma."

"You are too subjective." Zheng Ren said calmly, "the court will not believe your subjective opinion."

"Then find objective evidence." Su Yun looked back and smiled. His black hair floated in front of his forehead.

"Take the subadventitia tissue and send it for pathological biopsy." Zheng Rendao, "focal lymphocyte infiltration in epicardium, coronary artery and aorta, myocardial myolytic necrosis, inflammatory cell infiltration and fibrous tissue proliferation are the most objective and powerful evidence."

The room was deserted. Zheng Ren's words hit the surrounding walls like stones, buzzing.

"Good!" Su Yun replied with certainty.
