What kind of patients are usually sent here for you to dissect? "Zheng Ren asked.
"Most of them are people who died in the hospital. There are also a small number of 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'll go to the city bureau, "Li Zhaosen said.
"Are you afraid?" Zheng Ren glanced at the deceased. The chest and abdomen had been dissected and had probably been seen.
Su Yun put on his clothes, put on gloves, and began to dissect.
"They're all dead. What's there to be afraid of? The living are the scariest," Li Zhaosen said.
With the gloomy atmosphere here, his words were quite effective. And the corpse was like an annotation, silently agreeing with Li Zhaosen's words.
Su Yun walked directly to the deceased's side and put the knife aside. He picked it up, pulled out the heart, and began to dissect it.
"There's no problem with the general structure of the heart," Su Yun said. "There's no congenital heart disease or organic lesions other than myocardial infarction."
Zheng Ren did not chat. He stood behind Su Yun and watched Su Yun dissect.
He knew what Su Yun was conflicted about.
If the deceased died because of a myocardial infarction, it meant that Da Liu, who had a dispute with the deceased at that time, had a certain degree of responsibility. At least part of the responsibility could not be shirked.
However, if it was not a myocardial infarction but a myocardial rupture, the medical staff who did the heart compressions at that time had a certain degree of responsibility.
He was in a dilemma.
The room was filled with the smell of internal organs, and the exhaust fan was not turned on. Zheng Ren frowned. He was really not used to this smell. He said, "Teacher Li, don't you usually turn on the exhaust fan?"
"Why would I turn on that thing? If I didn't wait for you, Boss Zheng, I could finish an autopsy in twenty minutes," Li Zhaosen said. "The smell hasn't even spread yet."
Zheng Ren really did not know how to describe Li Zhaosen.
"Moreover, the autopsy of the dead smells much better than the cadavers. Especially the cadavers that have just been fished out of the pool, the smell of formalin. After the autopsy, it's like they have just broken up. "
"Do you have a girlfriend?" Zheng Ren stared at Su Yun dissecting the heart and asked casually.
"No, with my job, who would want to marry me?" Li Zhaosen did not care and answered casually.
"The rupture of the heart occurred near the apex of the posterior wall of the left ventricle. There was an acute large area of myocardial infarction in the rupture area. The rupture is irregular, about 1.2 x 0.8 cm. "Su Yun continued to observe.
"The scope of the myocardial infarction is relatively large. Myocardial necrosis …"
As he spoke, he hesitated for a moment.
"Boss, do you feel that something is strange?" Su Yun asked.
"Open three coronary arteries and take a look. Are you confident? Don't cut your hand, "Zheng Ren said.
"Tsk!" Su Yun said, "I've performed 122 cases of coronary artery bypass surgery."
"Just be careful." Zheng Ren said, "The range of myocardial necrosis is too large. The entire heart seems to be damaged, like a rotten peach."
"This situation is very rare. When I dissected it, I also felt that it was strange." Li Zhaosen said, "I've dissected patients with myocardial infarction. Even people in their seventies or eighties weren't as serious as him."
Su Yun did not dissect the coronary artery according to Zheng Ren's instructions. He began to examine the heart.
"What are you thinking about?" he asked.
"It smells bad," Su Yun said. "It smells like rust or something. Is it caused by some chemical poisoning?"
"The liver has been dissected. There's not much of a problem. At most, there's a little alcoholic liver, but it's not very serious," Li Zhaosen said.
"Strange." Su Yun changed the direction of the heart.
"Don't touch the coronary artery first. Dissect the left heart. The heart is large overall and the ventricles are hypertrophic, especially the left ventricle, "Zheng Ren suddenly said loudly.
An adult's heart was about the size of a fist. A fist the size of a sandbag was just an adjective. Generally speaking, the heart was not that big.
Especially since a large part of it was in Su Yun's hand, it was difficult for Zheng Ren to see the size clearly.
"I knew something was wrong!" Su Yun said. "It's my first time doing an autopsy. I actually forgot such a big thing."
As he spoke, he began to dissect the heart.
Su Yun's scalpel was different from Zheng Ren's. His technique was more exaggerated, or rather, more flashy.
"The whole heart is enlarged, and the volume is about 10% larger than normal. Take the left ventricle as an example. The left ventricle is dilated and hypertrophic. It is considered that the deceased had left heart failure when he died. There's bleeding in the myocardium and a large amount of myocardial fibrosis! "Su Yun explained as he dissected.
"Myocardial contraction zone …" Soon, his words stopped.
"Necrosis?" Zheng Ren's eyes narrowed.
"I was just about to look here when I received your call, Boss Zheng," Li Zhaosen immediately explained when he saw this at the same time.
The myocardial contraction zone necrosis meant a very big thing. Basically, only methamphetamine abusers would have such a physiological change.
It was not occasional use, but abuse, long-term and in large quantities!
"F * ck!" Su Yun cursed excitedly. "Boss, I know what this strange smell is!"
Zheng Ren also wanted to know what it was.
People who used methamphetamine had a smell on them.
There was a huge gap between Zheng Ren and Su Yun's social circle and this kind of people. They rarely saw such people, so they did not immediately react.
Li Zhaosen's situation was the same.
What he read in the book was only boring words, unable to replace the smell with his nose. Li Zhaosen quickly ran to turn on the exhaust fan. He seemed to feel a little better when he heard the buzzing sound.
"The mechanism of cardiomyopathy is multifaceted, including excessive catecholamines, coronary artery spasm and ischemia, increased reactive oxygen species, mitochondrial damage, changes in myocardial metabolism, and direct toxicity."
Su Yun nagged as he dissected. Zheng Ren knew he was thinking.
There was a turning point, even a reversal.
"Chronic poisoning causes myocardial inflammatory cell infiltration, myocardial hypertrophy, myocardial fibrosis, dilated cardiomyopathy, accelerated atherosclerosis, aortic dissection, and even cardiac rupture," Su Yun said. "Now, it can almost be determined that the heart rupture was caused by methamphetamine poisoning. It has nothing to do with external injuries."
"You're too subjective," Zheng Ren said calmly. "The court won't believe your subjective opinion."
"Then find objective evidence." Su Yun turned around and smiled, the black hair on his forehead fluttering in the wind.
"Take the tissue under the epicardium and send it for pathological biopsy," Zheng Ren said. "Focal lymphocyte infiltration under the epicardium, coronary artery, and aorta, myocardial myolytic necrosis, inflammatory cell infiltration, and fibrous tissue hyperplasia. It's the most objective and powerful evidence. "
The room was cold and empty. Zheng Ren's words were like stones, hitting the walls and making a buzzing sound.
"Okay!" Su Yun answered with certainty.
