"What kind of patients are usually sent to you for dissection?" Zheng Ren asked.
"Most of the people who died in the hospital are brought here, and there are also a few people who died in fights. I can't touch the really big and important cases." Li Zhaosen said: "Even if technical assistance is needed, I go to the city bureau. ." Li Zhaosen said.
"It's just you, are you afraid?" Zheng Ren glanced at the deceased. He had probably seen the dissection of the chest and abdomen.
Su Yun put on clothes and gloves and began to dissect.
"They are all dead. What is there to be afraid of? The living are the ones to be feared." Li Zhaosen said.
Considering the gloomy atmosphere here, his words are quite powerful. And that corpse was like a comment, silently agreeing with Li Zhaosen's words.
Su Yun walked directly to the deceased and put the knife aside. He directly picked it up, took out the heart, and began to dissect.
"There is no problem with the general structure of the heart." Su Yundao said, "There is no congenital heart disease or organic disease other than myocardial infarction."
Zheng Ren didn't want to chat. He stood behind Su Yun and watched Su Yun dissect.
He knew where Su Yun was struggling.
If the deceased had a heart attack, it means that Liu, who had a dispute with the deceased at the time, is jointly and severally responsible. At least there is some responsibility, which is unshirkable.
But if it was not death from myocardial infarction but myocardial rupture, the medical staff who performed cardiac compressions at that time would have certain responsibilities.
A dilemma.
The room smelled like offal, and the exhaust fan was not turned on. Zheng Ren frowned, really not used to this smell, and said, "Teacher Li, don't you usually turn on the exhaust fan?"
"Why are you driving that thing? If I hadn't waited for you, Boss Zheng, to do an autopsy, I would have done it in twenty minutes." Li Zhaosen said, "The smell hasn't even dissipated yet."
Zheng Ren really didn't know how to describe Li Zhaosen.
"And the dead people who were autopsied smelled much better than the anatomy teacher. Especially the anatomy teacher who had just been fished out of the pool, smelled like formalin, and after the autopsy, he looked like he had just lost his love."
"Do you have a girlfriend?" Zheng Ren asked casually as he watched Su Yun dissect his heart.
"No, with my job, no one is willing to marry me." Li Zhaosen didn't care and replied casually.
"The heart rupture occurred in the posterior wall of the left ventricle near the apex, and there was an acute large-scale 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... "
As he spoke, he hesitated.
"Boss, do you think anything is weird?" Su Yun asked.
"Open the three coronary arteries and take a look. Are you sure? Don't cut your hand." Zheng Ren said.
"Tch!" Su Yundao said, "I have performed 122 cases of coronary artery bypass surgery."
"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 rare. When I did the autopsy, I felt strange." Li Zhaosen said, "I have done autopsies on patients with myocardial infarction, and the conditions of the elderly people in their 70s and 80s are not as serious as his."
Su Yun did not directly dissect the coronary arteries as Zheng Ren said. He began to examine the heart.
"What are you thinking about?" Zheng Ren asked.
"The smell is unpleasant." Su Yundao said, "It smells like rust. Is it caused by some kind of chemical poisoning?"
"The liver has been dissected and there are no major problems. At most it's a bit of alcoholic liver disease, but it's not very serious." Li Zhaosen said.
"Strange." Su Yun changed his heart.
"Ignore the coronary arteries first and dissect the left heart. The overall heart is too large and the ventricles are hypertrophic, especially the left ventricle." Zheng Ren suddenly said loudly.
An adult's heart is about the same size as my fist. A fist as big as a sandbag is just an adjective. Generally speaking, a heart is not that big.
Especially since a large part of it was in Su Yun's hands, it was difficult for Zheng Ren to see the size clearly.
"I just said something is wrong!" Su Yun said, "This is my first autopsy, and I forgot such a big thing."
As he spoke, he began to dissect the heart.
Su Yun's use of the scalpel is different from Zheng Ren's. His technique is more exaggerated, or more dazzling.
"The whole heart is enlarged, and the volume is about 10% larger than normal. Especially the left ventricle, which is dilated and hypertrophic. It is considered that the deceased was accompanied by left heart failure when he died. There is bleeding in the myocardium, and a large amount of myocardial fibrosis!" Su Yun explained while dissecting.
"Myocardial contraction band..." Soon, his words stopped.
"Necrosis?" Zheng Ren's eyes narrowed.
"I was just about to look here when I received a call from you, Boss Zheng." Li Zhaosen also saw this at the same time, and he immediately explained.
Necrosis of the myocardial contraction band means a very important thing - basically only methamphetamine abusers will have this physiological change.
Not occasional use, but abuse, long-term and large amounts!
"MD!" Su Yun cursed excitedly, "Boss, I know what this weird smell is!"
Zheng Ren also wanted to know what it smelled like.
People who smoke methamphetamine have a smell.
There is a huge gap between Zheng Ren and Su Yun's social circles and such people, and they rarely see such people, so they did not react immediately.
Li Zhaosen is in the same situation.
What you see in books are just boring words, which cannot replace the smell through your nose. Li Zhaosen hurriedly ran to turn on the exhaust fan. It wasn't until he heard the buzzing sound that he seemed to feel better.
"The mechanism of cardiomyopathy is multifactorial, including catecholamine excess, coronary artery spasm and ischemia, increased reactive oxygen species, mitochondrial damage, changes in myocardial metabolism, and direct toxic effects."
Su Yun was chattering while dissecting. Zheng Ren knew that he was thinking.
Things have turned around, even reversed.
"Chronic poisoning can cause changes such as myocardial inflammatory cell infiltration, myocardial hypertrophy, myocardial fibrosis, dilated cardiomyopathy, accelerated atherosclerosis, aortic dissection and even cardiac rupture." Su Yundao, "Now it can almost be determined that methyl The heart rupture caused by amphetamine poisoning has nothing to do with trauma.”
"You are too subjective." Zheng Ren said calmly: "The court will not believe your subjective opinions."
"Then find objective evidence." Su Yun turned around and smiled, not recognizing his relatives with black hair floating on his forehead.
"Take the subepicardial tissue and send it for pathological biopsy." Zheng Rendao, "Focal lymphocyte infiltration in the subepicardium, coronary arteries and aorta, myocardial myolytic necrosis, inflammatory cell infiltration and fibrous tissue hyperplasia. It is the most objective, The strongest evidence.”
The room was deserted, and Zheng Ren's words were like stones, hitting the surrounding walls, making a buzzing sound.
"Okay!" Su Yun replied firmly.
